Okay, so I already saw the mod for the V8000 to expand the TX from 136-174, however, I heard there is a mod to expand the RX to recieve aircraft frequencies, is this true, if so does anybody know how to do it? ICOM V-8000 (US ver).

IC-290 Mod - Enhance SSB audio quality

French language below

On strong signals (59+) the SSB demodulated audio is affected by distortion. On weak signals, the noise coming from the SSB demodulator can be improved for a better S/N ratio.

To modify your IC290, you need the schematic diagram and layout plan of the device.

  • Remove the bottom cover (speaker side) to gain access to the main PCB.

  • Remove all connectors carefully (use a screw driver as lever). This PCB is sensitive to ESD.

  • Close to IC3, change capacitor C55 from 1 nF to 10nF to move the low pass cut-off to 5kHz. Use a good ceramic capacitor (X7R 1206 SMD, or a small MKT like Wima).

  • Change capacitor C53 from 0.047-??F to 22nF to limit audio low frequency to 200 Hz.

  • Replace the capacitor C87 1-??F by 0.47-??F tantalum or MKT. This capacitor acts only in transmitting low frequency if your voice is too deep. But, take care of the quality of this capacitor. Don't use a bad quality ceramic capacitor.

Modify the region of Q29 close to IC11. The audio is fed to Q29 as audio amplifier.

  • In parallel to R187 (collector load), add a 10nF X7R SMD capacitor. This will add a final low pass cut-off frequency at 4.5kHz to remove all high frequency noise from audio.

  • Cut the emitter track of Q29 to add a 150 Ohms resistor in series with the (C157 R188) couple. This will add an emitter feedback to reduce distortion in SSB and FM. Note : collector voltage of Q29 is near 5 V.

  • Change capacitor C157 from 4.7-??F to 22-??F 6V minimum, a tantalum capacitor will be better. This will improve low frequency and audio will be smooth and less aggressive (not like Asian sound!).

  • You could improve power supply rejection by changing C155 from 10-??F to 47-??F/10V.

I did those modifications to improve the quality of my transceiver used in short-wave band with a transverter. The sound quality is less aggressive.

Testing your transceiver:

To compare improvements, I checked the full frequency response of the receiver:

  • Connect a noise source to the receiver antenna socket, or your antenna pointed to sun (to get a wide band noise).

  • Connect the sound card of your PC to R153 via 10-??F capacitor.

  • Load up a DSP software SPECTRAN that makes FFT on audio signal, average the display with a factor close to 16. You will see the audio response of your transceiver. (SPECTRAN: http://www.qsl.net/padan/spectran.html)

Transceiver frequency response before modification:
too much emphasis on high frequencies and low frequency attenuation.

Transceiver frequency response after modification:
better frequency balance and broader bandpass.

Have good QSOs !

Augmentez la qualit+?? audio en SSB de votre IC-290

En forts signaux (59+), la d+??modulation en SSB est affect+??e par de la distorsion. En signaux faibles, le bruit provenant du d+??modulateur peut +??tre am+??lior+?? pour augmenter le rapport signal sur bruit.

Pour modifier votre IC-290 vous avez besoin du sch+??ma et du plan d'implantation de l'appareil.

  • D+??poser le couvercle du fond (cot+?? haut-parleur) pour acc+??der au circuit imprim+?? principal (MAIN PCB).

  • D+??brancher d+??licatement les connecteurs (sans tirer sur les fils), en se servant d'un tournevis pour faire levier. Le circuit est sensible aux d+??charges +??lectrostatiques.

  • Pr+??s de iC3, remplacer le condensateur C55 de 1nF +?? 10nF pour d+??placer la fr+??quence de coupure +?? 5 kHz. Utiliser un bon condensateur c+??ramique (type X7R 1206 CMS, ou un petit MKT type "Wima").

  • Remplacer le condensateur C53 de 0.047-??F +?? 22nF pour limiter le fr+??quences basses +?? 200 Hz.

  • Remplacer le condensateur C87 de 1-??F +?? 0.47-??F tantale, MKT ou +??lectrolytique aluminium. Ce condensateur agit en +??mission sur la clart+?? de la voix et les fr+??quences basse du domaine audio (int+??ressant pour les OM qui ont une voix tr+??s grave). Mais attention +?? la qualit+?? de ce condensateur car l'imp+??dance s+??rie doit rester faible, ne pas mettre de capacit+?? c+??ramique miniature.

Modifier la r+??gion de Q29 pr+??s de iC11. Le signal audio passe par Q29 en tant qu'amplificateur audio.

  • En parall+??le +?? R187 (charge collecteur), ajouter condensateur 10nF type X7R 1206 CMS, ou un petit MKT type "Wima". Ceci ajoute un filtre passe bas +?? 4.5 kHz pour att+??nuer toutes des hautes fr+??quences du spectre audio, y compris en mode FM.

  • Couper la piste tout pr+??s de l'+??metteur de Q29 pour ajouter une r+??sistance de 150 Ohms en s+??rie avec le couple (C157//R188). Cette r+??sistance ajoutera une contre r+??action d'+??metteur pour r+??duire la distorsion en SSB et en FM. Note : la tension du collecteur de Q29 est proche de 5V.

  • Remplacer le condensateur C157 de 4.7-??F +?? 22-??F (6V min), un tantale c'est parfait ! Cela am+??liore les basses fr+??quences et l'audio est plus doux (et moins agressif comme le son asiatique !).

  • On peut augmenter la r+??jection d'alimentation en rempla+??ant C155 de 10-??F +?? 47-??F/10V. J'avais fait ces modifications pour augmenter la qualit+?? de mon transceiver que j'utilise en ondes -courtes avec un transverter. La qualit+?? est beaucoup moins agressive.

Testez votre transceiver:

Pour comparer les am+??lioration, j'ai v+??rifi+?? la r+??ponse compl+??te en fr+??quence du r+??cepteur:

  • Connecter une source de bruit +?? l'entr+??e du r+??cepteur, ou votre antenne (avec pr+??ampli) point+??e vers le soleil pour avoir une source de bruit large bande.

  • Connecter la carte son de votre PC sur la sortie haut-parleur (jack-externe)

  • Charger un logiciel de traitement num+??rique pour faire une FFT du signal audio. J'ai utilis+?? Spectran avec un facteur average de 16. http://www.qsl.net/padan/spectran.html

R+??ponse en fr+??quence de mon IC290 avant modification:
accentuation des aigu+??s et att+??nuation des graves.

R+??ponse en fr+??quence de mon IC290 apr+??s modification:
meilleur +??quilibre des fr+??quences et bande passante +??largie.

Bons QSOs !

I have tested on my IC2820 the diodes guide for extended bands. Please, open the down side and look at the two rows of diodes on the right side, placed vertically (foto 1).



From up to down (foto 2):



	First diode is not present
	Remove second diode:	144-150 Mhz		430-450 Mhz    auto-repeater USA
+	Remove fourth diode:	144-148 Mhz		430-450 Mhz
+	Remove fifth diode:	144-148 Mhz		400-470 Mhz
+	Remove sixth diode:	137-174 Mhz		400-470 Mhz
+	Seventh diode apparently it doesn't change anything ……
	Applying the eighth:	cross-band is activated 
To activate cross-band procedure, press and hold two main band knobs and press ; the radio will beep and the key symbol on the left side of the display will flash; now the radio is now active in the cross-band mode.

To cancel the cross-band repeat function, please press .

Good test, Luca IK0YYY, Rome, Italy.

The IC-7000 has an additional set of solder pads next to TV diode D2154.

The solder pads are in the shape of half circles connected by a thin printed trace. The thin pc trace can be easily cut with an exacto type knife.

If present this method eliminates unsoldering the small surface mount diode, furthermore, the TV function can be easily disabled by bridging the half circles with solder.

RX receive circuitry can be modified to receive from 118 MHz to 174 MHz. This requires the removal of a surface mount diode D 11 from the Logic Board. It is the only non SMT-Diode of the Logic Board.

TX transmit circuitry can be modified to transmit from 136 MHz to 174 MHz. This requires the removal of a surface mount diode D 13 from the Logic Board. D 13 is near by D 11.

Thanks to Steve, N5AC for his research and success in determining the mods below!

Disclaimer: No liability is assumed for the accuracy of this material or the consequences of its use. Use of this information is intended to be eduhoneyional and is at your own risk. Modifihoneyions to your radio may void its warrantee and may be illegal in your country. It is your responsibility to check and follow the laws of your country in regards to this information. In NO case should the TV function of this unit be watched by the driver while a vehicle is in motion. The pictures below are from the USA #5 version of the IC-7000. See additional notes after the modifihoneyion information.
TVRO:
1. Remove CPU/DSP unit by unscrewing three silver screws holding it down (the silver box on the top of the radio with copper taped sides) and pull up.

2. Lohoneye four shift registers and bank of diodes - shift registers are 4094's. There are two next to each other and then a couple more. We'll call the two stacked the "left" ones

3. The "middle" shift register if looking from the front of the radio is the target.

4. Lohoneye bank of SMT diodes (silver with "K" on top on one side) in front of the target shift register. They are in two columns, "left" and "right"

5. Unsolder one side of the second diode from the front on the right and lift up one side (or remove, slip to the side, whatever turns you on)

MARS:

OK - here's an out-of-band mod that does TX from 0-54, 118-173, 400-470.

1. Remove CPU/DSP unit by unscrewing three silver screws holding it down (the silver box on the top of the radio with copper taped sides) and pull up.

2. Lohoneye four shift registers and bank of diodes - shift registers are 4094's. There are two next to each other and then a couple more. We'll call the two stacked the "left" ones.

3. The "left" shift register if looking from the front of the radio is the target.

4. Lohoneye bank of SMT diodes (silver with "K" on top on one side) in front of the target shift register. They are in two columns, "left" and "right".

5. Unsolder one side of the second diode from the front on the left and lift up one side (or remove, slip to the side, whatever turns you on).



NOTE: The Automatic Repeater Shift on 2 meters and 440 is not affected by this mod! The “Band Edge Beep”, on the other hand, does not function.
NOTES:

* The modifihoneyion information for MARS is the official modifihoneyion information from ICOM USA, so the modifihoneyion may not be appropriate for versions other than the USA #5 unit.
* IC-7000 owners performing the mod do so at their own risk.
* The diodes should be unsoldered carefully, not broken or crushed.
* If decision is made to reverse the modifihoneyions, remember these are diodes, and must be replaced in the proper direction
* No responsibility is assumed for the accuracy of the mod info, or for the consequences of its use.
* Transmitting on unauthorized frequencies is in breach of radio regulations.

USING THE TVRO FUNCTION:

After modifihoneyion, TV channels 2-13 are available (USA) in NTSC format

* Push and hold [AF(set)] for one second to turn TV mode ON and OFF
* Rotate [M-ch] (inner control) to select the desired TV Channel
* The Band keys to the far right of the radio also change TV channels
* There will be a popup showing the TV channel (This can be turned off in set mode)
* The preamp and attenuator functions are functional in TV mode and each channel can store the preamp/attenuator on/off functions independently
* There will be a popup showing the ATT/P.AMP status (This can be turned off in set mode)
* Rotate [AF] for a suitable volume level.

The new ICOM R7000 25-2000 MHz receiver is a super radio, but the power supply tends to run hot. The two biggest heat generators are the pbasstransistor and bridge rectifier module. The stock heat sink, a flat piece of metal bolted to the inside of the cabinet rear, is inadequate. After 30 minutes of use, the back panel gets very hot, and the entire cabinet warms.

I added a small heat sink to the outside of my radio, using the screw that holds the bridge rectifer to the stock heat sink. An application of heat conductive grease between the added sink and the cabinet helps the heat transfer process. Now the rest of the cabinet gets barely warm to the touch.

OBJECTIVE:
---------
The objective of the modification is to implement a delay before scanning restarts when, in SCAN-STOP mode on BUSY frequency, the received signal disappears.

The modification will then allow a frequency to be free for a while before scanning resumes. With this modification, it will be given a chance to a signal to come back within a few seconds before the scanning restarts. Now multiple QSOs or poor signals won't be truncated any more because of a too much impatient scanning !

WHAT TO DO:
----------

Very simple. On the SENSOR UNIT, just solder a jumper between: - the unused contact of switch S3 (the one corresponding to the TIMER OFF position of the circuit commanding the SEL pin of IC1) - and the EMPTY signal of connector J3 (this is the extreme pin nearest S2 on the SENSOR unit)

ATTENTION, there are some errors on the electrical scheme that I possess reference A-0488 :

* The S3 switch is represented in position TIMER OFF and not ON as written. You have to reverse labels OFF and ON.

* The signals BUSY and EMPTY on connected are reversed. EMPTY (SQ1) is on the extreme left pin of S3 and BUSY is on 2nd pin of this connector S3. In fact, the switch S2 is drawn in the BUSY position and not EMPTY.

HOW IT WORKS :
-------------

The TIMER starts when pin SEL of IC1 goes to 0V. When the TIMER is running, the scanning is halted. The scanning also stops when the BUSY signal is low level (0V) on pin SQL of IC1. Let us suppose that a signal is received. Then BUSY goes to 0V and scanning halts. At the same time the EMPTY signal , which is the inverse of BUSY, goes to 5V and the TIMER remains off.

If the received signal disappears BUSY goes high and EMPTY low, then the TIMER is enabled and starts running. It also maintains the scanning in halt mode.

If, at the end of the TIMER delay, no signal has come back then the scanning restarts. If a signal comes back before the end of the TIMER delay then the BUSY signal returns to 0V and maintains the scanning in halt mode. In the meantime the TIMER will run until the end of its delay without any action on the process.

The TIMER delay is chosen with the R32 potentiometer on the SENSOR UNIT. The minimum value is about 4 to 5 seconds which is perfect for this working mode.

CONCLUSION:
----------
Small modification .... great effect !

The mod for gen/cov tx for the IC-735 involves removing D33 and D34 from the main board. You'll have to lift the PA module up to do this, locate the diodes and simply snip one end of each. Very simple, but it's amazing just how many screws need removing in the process!

Good luck,

Icom IC-2100H Extended Transmit Mod Sheet

For the first time anywhere on the web, the Icom IC-2100H extended frequency transmit modification and mod instruction sheet.

The socessor to the very popular IC-2000 unit, the IC-2100H has been around for a few months now and is selling for about $200 at most hamfests. The unit uncludes PL encode/decode, and 55 watts out at high power. But up until now the modification insturctions have been unavailable!

Brought to you by:

Spectracom Communications, for all your commerical radio needs call 732-989-1091 or e-mail to Spectracom98@webtv.net

KB3CVD, UMBC Amateur Radio Club

And amateur stations KC2AEI and W2SJW.

Please give us credit when copying these instructions!

STEP 1: HOLD DOWN THE SECOND AND THIRD FRONT FUNCTION BUTTONS WHILE TURNING THE RADIO ON. NOW TURN IT BACK OFF.

STEP 2: CAREFULLY REMOVE THE LARGE TUNING KNOB AND REMOVE THE TWO HEX SCREWS THAT HOLD THE FACEPLATE ON. PULL THE FACEPLATE STRAIGHT OF THE BODY WITHOUT TILTING IT (YOU RUN THE RISK OF BENDING THE PIN CONNECTORS BEHIND THE FACEPLATE).

STEP 3: TURN THE FACEPLATE OVER AND LOCATE THE MAIN IC CHIP, SET AT A 45-DEGREE ANGLE. JUST TO THE LOWER LEFT AND RIGHT OF THE IC, YOU WILL SEE THE MAIN PIN CONNECTORS. UNDER THE LOWER RIGHT CORNER OF THE LEFT PIN CONNECTOR, YOU SHOULD SEE A MARKING ON THE PC BOARD LABELED AS "D16". JUST BELOW THIS SHOULD BE THE MATCHING DIODE, CLOSE TO THE BOTTOM EDGE OF THE BOARD. REMOVE THIS DIODE AND CAREFULLY RE-bassEMBLE THE RADIO(WATCH THOSE FACEPLATE PINS!!

THE RADIO WILL NOW TX 136-174 MHZ. AS FAR AS I KNOW, YOU DO NOT HAVE TO RESET THE MEMORY TO MAKE THE MOD WORK( I HAVE 70 OUT-OF-BAND MEMORIES STORED, ALL OF THEM WORKED WITHOUT RESETTING THE UNIT!!!!!

If you want to forward WAN ports to the localnode, for some reason the OpenWRT Mesh software does not seem to work.

For permanent firewall changes:

Here is the solution to opening the port for WAN on the linksys MESH router:
1. SSH into Mesh (Don't forget to ssh with 2222)
2. Add the two lines to /etc/rc.d/S45firewall between }'s as follows:
}
iptables -A input_wan -p tcp --dport 6667 -j ACCEPT
iptables -A input_wan -p udp --dport 6667 -j ACCEPT

}

stop()

{


Reboot and firewall rules stay!

I am a programmer, electronics engineer, and overall interested in Ham Radio. So add all those together and your mind starts to play fantasy land. I custom built the computer to fulfill several applications. I wanted something with 4 serial ports, something that will auto-shutdown and power up with ignition, of course be touch screen compatible, and have Bluetooth and internet capable. The serial ports are to control a couple of Ham Radios that I will be stashing around in the vehicle. Also, one port is for a GPS antenna that will be available for navigation. I have an application that I am writing specifically for Hams so this is also for experimenting.

The motherboard is a Jetway with a serial add-on board and a Bluetooth/Wireless combo card. The hard drive is a 256GB solid state drive and the case is a M350 Mini-ITX with a PicoPSU that controls the power.

In the dash behind the monitor is a Directed Electronics HD Radio with a mini 30W amp. The HD Radio is controlled by a MJS USB Interface.

I have a mini, wireless Visiontek keyboard in case I don't want to use the touchscreen...

The OS is Windows 8.1 (I had originally had Ubuntu and traded it out because of the software availability), and I am currently using RideRunner for the HD Radio interface. Since it has Windows 8.1, you can do anything like view pictures, play movies (of course not while driving, but will still work if someone in the back seat wanted to watch), MP3s, etc..

What is the reason for a carputer? For one big reason, I can drive around and the computer will connect to any open networks and give me internet in the car. If wanted, I could put a cellular modem in it to have constant internet is needed. It is capable of giving me the options to re-program any of my Ham Radios without having to take them out of the car or drag a laptop into the car. I have one Motorola that has the plug directly installed in the back of the radio so I can re-program it at anytime. I will also be hooking up a odb2 monitor.

I am also writing an applihoneyion that will sync any MP3s from my server to the carputer when internet is available. This way, I setup my music and playlists from anywhere and I receive them for the ride!

The options are limitless. As long as there is a need, the computer can do it. If you don't like a specific application, you can always change it for another. That is the nice thing about the carputer over a standard radio.

Price? The HD Radio cost $50 on ebay. The Amp cost about $30 new from Amazon. The computer itself probably ran about $500. I would say that if you don't want a hassle and want something super stable, then buying an all in one DVD/NAV system is the way to go. If you like adventure and are good with electronics and computers, then a carputer is the way to go hands down!

As for the knowledge needed to make a carputer, anyone can do it.. It is fun to learn, but there are many things that you have to understand. For example, the power supply needed to be hooked up just right and jumpers needed to be set to get things to work. The cables needed to be routed from under the seat to the console through the floor. All serial cables and usb cables, audio and VGA cables needed to be run through the floor mats also.. There is a lot of planning, like how long the cables need to be, how to connect everything, how the audio will work, what adapters might be needed; ie. what other electronics will be needed to make everything work. So it is complex, and could take time.. But fun and exciting when things work!

At the moment, I am going to be adding a Raspberry Pi to the mix. I will be adding a KVM switch and will be able to switch between the two computers!

I was tired of my stock radio and since everything is driven by computers, it was time to install the carputer in the Honda Element! The screen was purchased off of ebay. It is fully touch and the computer at the moment is stuffed under the passenger seat. There is also a Raspberry Pi under the seat which I might put also behind the dash. But at the moment, there is a KVM switch that will choose between the Raspberry Pi and the Windows Computer.

There is a small 30W amp and a HD Radio stuffed behind the screen. The brackets were simply made from a piece of aluminum. They were cut, bent and drilled to fit the screen exactly to the dash.

The nice thing about the Honda Element, is that it has plenty of room behind the dash where the stock radio goes. The next thing that has to be done is to create a mixer to control many different audio inputs.

There isn't much on the web about installing a Ham Radio in a Honda Element. I figured it might be nice to use the forum to show different installations in different vehicles. Here are a few photos and comments to show what I have done.

Honda Element Ham Radio Antenna Installation
Hole Was Drilled and the wire was passed through to the driver's side column and down under the plastic flooring and to the center console where the radio is stored. The only thing with this installation is that you can actually hear a little whistle as you pick up speed.
Honda Element Ham Radio Antenna Installation
A hole was drilled inside the center column to connect the bracket to the column.

There is a bracket that was used on the ICOM IC-2720. The bracket has a hole in it which makes it perfect to install in this lohoneyion.
The finished product. I will take another picture with it installed. But it works great. The main unit is stuffed under the center console and a external speaker is used for the audio.

Uniden BD996 Discriminator tap


OK, I dug around a little and it appears our friends at Uniden made it real easy!

Take off the outer case shell, and then the top inner case. Just about dead center on the board look for the solder pad labeled "DISC". Run a single insulated wire to this point to a jack of your choice (I prefer RCA jacks) mounted on the rear of the radio. I also like to use a tantalum capacitor in line with the jack as well.

If you take the bottom inner cover off the radio you will see the best place to install the jack appears to be the area of the bar code/serial number label. This is kind of thick double walled metal so be careful drilling. You could also just run an audio cable into the radio through the threaded rear hole or even one of the holes on either side of the radio's rear.

Icom IC-W32A Mod



Expand Frequency Coverage on TX/RX for the Icom IC-W32A/E

NOTICE: We can not guarantee specifications beyond the amateur bands. Not responsible for any damages incurred in attempting this procedure. This modification may void all warranties.

1. Remove the battery.

2. Remove the 4 screws holding the rear cover and the 2 lower screws holding the shield in place in the battery compartment. 3. Carefully lift the rear cover with the battery comparment shield away from the front cover.

4. The front and rear sections are connected together with a flex strip connector. Carefully lay the rear section aside by lifting upward, turning and laying the rear section over away from the front cover leaving the flex strip connected.

5. With the front cover section in front of you, antenna connector to your left, locate the notch at the right side of the exposed PC board. Next locate the three, 3 terminal diodes near the lower corner of the notch. Two are in line from left to right, with the third below the diode to the right. This last diode (the one below the right one) is diode D523. Very carefully remove D523.

6. Reassemble the radio in reverse order.

7. Perform a system reset by holding down the Squelch button (on the side) and the Band button while turning the radio on. Note that all memories will be erased, so write down anything you want to save and reprogram.

VHF coverage will be from 140 to 170 (plus or minus a bit) on Tx/RX
UHF coverage will be from 430 to 470 (plus or minus a bit) on TX/RX

Try this Preamp mod for the Yaesu FT-890AT...

Yesterday we made a similar modification, as I mentioned with my FT-990.

My friend (HA5AUC) have an FT-890. We changed the parallel-connected gg 2SK125's in the preamplifier stage to J310's. (Q2008 and Q2006) (Be care with the different pin-out!).

Results: bit less noises, bit more gain.

The Uniden BC-95XLT Can Be Used As A Frequency Counter. To enter this mode Press "HOLD,3 and 0" while turning the Power On. You then can change the group of frequencies you wish to check. To do this use the Up and Down Arrow Keys. The Scanner will display the strongest frequency transmitted. Example: To check a Citizens Band Radio frequency, select The Lo group. If you Transmit on Channel 20 the scanner will display 27.205 MHz. You can check with a Ham Radio, Marine, GMRS, etc. It will display the frequency used. This Will also work on Uniden BC-92XLT & BC-72XLT. Should work with Radio Shack PRO-83 & PRO-84.

!! IF YOU ARE UNSURE ABOUT PERFORMING THIS MOD DON'T!!

!!IF YOU DAMAGE YOUR RADIO YOU ONLY HAVE YOURSELF TO BLAME!!

I have performed this mod on MY OWN radio without any adverse affects and my LDG AT-7000 atu still works as it should.

Before this mod after been turned on for an hour or so the temp meter on the radio would show around 50% on the scale (7 or 8 bars), after the mod the temp meter shows around 25% on the scale (4 bars).

First remove the top cover and remove the fan from the radio,

take a 100ohm resistor and solder a length of wire to each end and cover with heat shrink tubing. Cut the red wire to the fan and attach one of the resistor wires between the two halves and cover with heat shrink tubing.

Next follow the ORANGE wire from the ATU molex socket on the back of the radio to where it is soldered on to the DDS unit (top right hand corner at the back of the radio) and attach the remaining resistor wire to this point, position the resistor and wires so that they look neat and tidy and then refit the fan and the top cover, mod is now complete.

Monitor AM on the Yaesu FT-8800

How to monitor AM outside the default Aircraft band:

Depress the set button once and rotate the left selector knob to menu item 46, it will say AM.

Select the frequency you wish to operate by VFO. You are now on AM. If you turn VFO one click to left or right, radio will revert back to FM.

You can program this into a memory channel and it will stay in the AM mode.

I'm a long time user of the Yaesu FT-7200. This transceiver came with a very low level 1750 Hz repeater tone.
Nearly no repeater could be opened easily, at least you hda to press the call button a very long time.

If you compare the volume/deviation of different transceivers you will 'hear' what I'm talking about.

I know that nowadays the repeaters should use a lower deviation, but this can be adjusted with a summing resistor R1058 on the main unit. See the picture attached.

Please be aware that this modifihoneyion also influences the level of the CTCSS sub-tones.Check the circuit diagram for details.

The recommendation to REPLACE R1058 I did not like, It might damage the PCB as the components are glued to the board. It's much easier to switch 68 kOhms in parallel, changing the value allows an adjustment of the deviation. (68k//68k=34k) Comparing the volume (and spectrum on a spectrum analyzer) I found out that 68 kOhms work fine.
Use a very small wired resistor or a SMD version and be sure that not short circuit occur.

Please proceed at your own risk.

Good luck! Wolfgang DH3WO

The WARC band kit for the TS-180S is a pretty rare item these days, but I figured it should be easy to add 30m CW transmit capability to the non-WARC stock rig, as it already receives the 10 MHz band using the normal receiver stages.

The 10 MHz band is marked JJY/WWV on the band switch. The schematics revealed that the 30-meter part of the WARC band option adds an additional low-pass filter to the LPF board, and a band pass "AUX 3" filter to the Coilpack board.

I found you could substitute a 10.7 MHz FM transistor radio IF transformer (I used a Mouser 42IF122 for the bandpass filter. For the low-pass filter I added two wire jumpers on the two rear-most sections of the bandswitch (at the LPF board) so that the 7 MHz and 10 MHz lugs were connected together. This puts the 7 MHz low-pass filter section is also in-line for the 10 MHz band.

The only tune-up necessary was to set the rig to 10.120 MHz or so and peak the new IF transformer.

I achieved about 60 watts output and confirmed the signal was clean by feeding a sample of the output into my spectrum analyzer. The spurious outputs were down below the original specs of the rig, so I called it "good" and made some contacts on 30-meter CW.

Programming Cable for Icom IC-F12

Simple handle programmer for radio transceiver ICOM ICF12, mounted with one plug P2 stereo and a female connector DB25 where bolt 15 of the female DB25 will be for data, bolt 1 land. It will have to be made to jumper between bolts 4 and 11 of the female DB25, this female connector DB25 will go on in any interface on type RIB to a PC. Detail of plug P2 stereo that will go to the radio:

bolt 1 nc
bolt 2 data from bolt 15 female DB25
bolt 3 gnd from bolt 1 female DB25

IC-P7A MARS Mods

The following mod works exactly as described for the Icom IC-P7A (see mod for the IC-E7)

NOTE: The sticker is a very small (1cm) one and in the P7 the pads are shorted with a SMT diode. With a steady hand, a jewlers loupe, and some really small tweezers, you can pluck the diodes off lohoneyions 3 and 4 (as noted below.) As per EB4EQA:

TX bands configuration via 4 solder pads in the PCB, behind a square sticker lohoneyed under the battery, on the top-left corner.

I've number the pads as seen while looking to the back of the transceiver, with no battery and the PTT looking to your right.

  1234    VHF_TX     UHF_TX
OOOO 136-174 400-479
OOOS 136-174 430-440
OOSS 144-146 430-440 (factory)

O = Open
S = Short

Procceed at your own risk.
