1. Set offset to 0.0

2. Select VFO (A).

3. Press and hold [SIMP/DUP] and [NOR/REV].

4. Dial in desired frequency.

5. Release [SIMP/DUP] button.

6. Select the other VFO (B).

7. Repeat steps 3, 4, and 5

if VFO (B) can not be set, transfer VFO (A) VFO (B) using the [WRITE] button as described on page 7, item 6, of the owners manual.

Note: [SIMP/DUP] must be out when the VFO is changed.

If the tuning knob is turned again, the radio will revert back within the normal band range.

The following modifications provide the following facilities.

- base band audio output, to utilizing digital transmissions such as AIS etc.
- a CTCSS filter insertion point, to eliminate annoying hum from the speaker Both these mods are best tackled at the same time.

1. Undo the screws holding the IF unit in position. Disconnect interconnecting cables.

2. As as indicated by the circuit diagram & board layout the baseband signal is taken from the discriminator output via a 10K resistor. Solder the 10K resistor to R97 on the solder side of the board and solder the other side to the inner braid of some thin audio coax cable. Connect the other end to the spare connector on the rear panel. Use some 3mm heat-shrink tube to cover the 10K resistor & hold in position with some hot glue. Connect the earth braid to a convenient earthing point with some insulated wire.

3. Remove C86 & connect some thin stereo coaxial cable (red = filter input & yellow=filter output) to each now empty pad. Connect the earth braid to a convenient earthing point with some insulated wire. The coaxial cable should be long enough to reach where the filter is installed. In my case I put this at the bottom where the IR receiver & Speech unit can be mounted.

4. Re-install the IF unit by screwing it in position & restoring the interconnecting cables.

5. An essential requirement is that both the input & output of the filter are capacitively coupled. For the filter unit, I used a recovered a CTCSS board from a Motorola SYNTRX FM radio. It contains the essential HP filter required to filter out the CTCSS tones, but in addition it contains a LP filter, which I will use to feed a CTCSS detector/display ( for info purposes). I used a hacksaw to cut off only the circuitry that I wanted. Alternatively a filter could be home brewed.

6. A switch could be provided to to enable straight through audio should this be required.

There are several ranges that can be selected by arranging diodes. First you can choose to only open up some areas and leave other frequencies (non amateur bands) locked.

40m amateur bands expansion (7.00MHz - 7.300MHz) : remove diode D1517
60m band expansion (5.255MHz - 5.405MHz) : remove diode D1515

Intro:

After returning home from purchasing a used (but in good condition) ICOM IC-745, initial check out revealed the transmitter did not function in AM transmit mode. A look and the owners manual revealed: "AM Receive Only" What!!!??? This is supposed to be an ALL MODE RADIO! In reality the words used were..."ALL BAND HF RADIO"

After analyzing this perplex situation I came to the conclusion ICOM must have been doing their part in trying to save precious spectral bandwidth by not incorporating AM transmit in this particular model.
No one really utilizes AM mode these days (including myself) but this radio has every mode ever conceived and to leave AM transmit out really aggravated me!

Below is the Mod of Mods for IC-745 owners:

(All Modifications administered to the "MAIN UNIT" board located under the top cover of the radio.) (Except for R21 Removal on the logic board for the Power Mod.)
Parts List:

8 pin diodes. Factory Diodes are P/N 1SS53. 1N914's are fine.
3 10k resistors 1/4 watt.
1 NPN TO-92 pkg. switching TX, 2N3904 or equivalent is fine.
Source Voltage Terminology and Locations:

R8 = 8 Volt Receive Mode Source
AM8 = 8 Volt AM Mode Source
FM8 = 8 Volt FM Mode Source
CW8 = 8 Volt CW Mode Source
RY8 = 8 Volt RTTY Mode Source
USB8 = 8 Volt USB Mode Source
LSB8 = 8 Volt LSB Mode Source

THE MOD

1.

Pull up the anode end of Diode D44. (located by TX Q39) Build the additional circuit below. This will enable the B+ to the product detector and 9 Mhz BFO oscillator.
The 9Mhz osc will now be working for AM transmit as well as BFO Rec.

       
                      C 
                        o to AM8  (Where the Anode of D44 was)

      to R239 o----|<----/    2N3904 or Equivalent 
                  D44    E 

2.

Remove R66. (Located by TX Q13) Relocate and solder one end of R66 to the bottom of the board. (The end that goes to R23 and R30)

(The schematic shows a "BREAK" in the land. By removing the resistor from the PC board this simulates the break.)

Solder two 1N914's to the other end of R66. (Cathode ends of course)

Note: All pin assemblies will be connected on the underside of the Main Unit PC board.

This is part of the Mode selection process, and turns off the mike shunt in AM mode. (So audio can pass to the Balanced Modulator.)

                            10K     pair 1N914's (add) 

3.

Solder one 1N914 diode (Cathode end) to the cathode connection of D15 (by TX Q19) under the board. Connect the anode to AM8.
This will enable the B+ to the Mic Amp stages and VOX ckts.

4.

Remove R31 (Located by TX Q8) Relocate and solder one end of R31 to the bottom of the board. (The end that goes to R30 and the base of Q8)

(The schematic shows a "BREAK" in the land. By removing the resistor from the PC board this simulates the break.)

Solder Three 1N914's to the other end of R31. (Cathode ends) Tie the Anode ends to LSB8, USB8, FM8. Function: This portion of the mod will turn Q8 off in the AM mode to unbalance the balanced Modulator (IC1) for AM full carrier operation.

5.

Remove R24 (Located by TX Q7, "Mike Shunt Ckt") Solder a 1N914 Diode (Cathode end) into one of the pc holes that R24 came out of. (The one end that connects to R65 by Xtal X1.) Tie the anode to AM8.
This will enable the 9 Mhz CW xtal to generate the correct center frequency for AM.

6.

AM Power Level Adjust (optional)Due to the duty cycle requirements of AM, output power of 40/50 Watts RMS should be the limit. Use the Front panel RF adj to reduce the output from 100 Watts or do the following:
1.

Connect a small 22 gauge (or so) wire from AM8 to the anode of Diode D26 by TX Q20. Add a series 10K resistor.
                AM8 o------\\/\\/\\/\\---------- o-->|-----o to Q20 
                             10K             |  D26 
               |________________________|    o 
                        Add this             o S1 
                                             | 

2.

Set the 50/100 Watt power switch (S1) in the 100 Watt Position if you desire 100 watt operation of SSB,CW,RTTY.
3.

Adjust R116 (in AM xmit mode) for a power output of 40 Watts RMS.
4.

What were doing here is using the 50 Watt low power ckt as the AM power adjustment control.
Paralleling another connection to FM8 will allow FM to be reduced in similar fashion (as well as AM) instead of the factory 100% duty cycle.
                FM8 o---->|-------/\\/\\/\\/----o 
                        1N914    |  10K      | 
                AM8 o---->|-------           o-->|-----o to Q20 
                        1N914                |  D26 
                                             o 
                                             o S1 
                                             | 

Note: When 10 Meters is selected port 28M (pin 47, IC3 on the logic unit) goes high, this turns on pin diode D27 on the main unit. This ultimately turns on the 50 watt (low Power) ckt allowing only low power operation from 28-30 Mhz?
I don't know why Icom did this? My guess is for 10 Meter FM overlooking the fact SSB/CW will be running reduced also. You may want to remove R21 (10K) on the logic board to remedy this situation. After R21 is removed you can limit the duty cycle on AM & FM as follows:
          FM8 o----\\/\\/\\/\\----->|---- 
                     10K   |   D27   | 
                           |         | 
          AM8 o----\\/\\/\\/\\----->|-------o to Q20 
                     10K   |   D26 
                           | 
                           o 
                           o  S1 
                           | 

Low power Adjustment R116 will now adjust output power for FM as well as AM.

Operation/conclusion:

The above AM/FM power mod is recommended. Higher power levels (Greater then 70/80 Watts RMS) result in severe distortion of the AM output signal.

Surprisingly the audio quality is quite good on AM xmit. (40/50 Watts) Several on the air discerning ears concluded the fidelity was quite acceptable. (Even from the Johnson Viking Guys on 3.880 (+-)).

For you skeptics wondering how an AM signal can sound acceptable through a 3Khz wide 455Khz SSB filter....................???

A quick turn to the schematic on the IF board depicts filter F-I1. (Ceramic filter CFW-455IT) This filter is a 6Khz wide ceramic filter used for AM receive mode. After the completion of the Mod this filter will be used for AM xmit also, by default! >>> It's in there!!

(Wasn't that a commercial once?)

Filter F-I2 (ceramic Filter CFT-455K14) or the optional FL-44A (SSB filter) is in operation for all other modes except FM. The optional FM board employs it's own filter arrangement.

That's it. Your all mode radio is now all mode!

I have scanned the Main Board and Logic Board to depict the electrical changes made to the circuits. I tried to nicely re-label all the changes using VISIO technical, but I ran into some offset problems.

The hand written changes will have to do for now until I can get Visio to work right. If you have any questions about this Mod feel free to ask via e-mail only (I'm hard to get a hold of) e-mail = n2fan@glensummit.com

This is not an easy cut the wire mod, you will need to have some good electronic technician skills. PhD's forget it! ...............

This Mod works, I still have my IC-745 after 8 years!

Notice: ICOM does not guarantee this to expand the frequency.

How to change full coverage transmit:
Remove the W805 jumper chip on MAIN board with a soldering iron.
Locate the jumper matrix located near the IC803.

What to do:
Remove bottom cover of ICOM IC-756. On the MAIN board you will see IF filters and a daughter board (DSP filter) on the right side. The W805 jumper and IC803 chip is lohoneyed under the DSP board. You have to remove the DSP board (carefully) and look for the part labeled IC803 and the line of jumpers (little green parts). When done, unsolder the W805 jumper. Install the DSP board and put the bottom cover back.

For Ham Mod remove the lower RIGHT diode (d14) from the pcb behind the lock button. it looks like this:

[d12] [d13]
[d11] [d14]

For TX expansion you have to leave (d11) intact and take the diode (d14) that you removed and install it at (d13).

http://www.hamradio.cc/images/forum/mods/icom_ic-77_Ham-TX-exp-1.jpg

If the diodes are all gone and no original diodes can be obtained normal 1N4007 diodes or similar can be used.

To extend frequency range (high end)from 135.975 to 136.975 MHz on the Icom IC-A20, proceed as follows:

1. Remove 4 screws holding back panel,
2. Remove 4 screws holding battery clip,
3. Remove battery clip and separate front and rear halves of radio
4. Remove 4 screws holding VOR unit mounted on the front panel so as to reveal Logic Unit.
5. Looking at the component side of the Logic Unit(opposite side to buttons and display), locate D711,

After the power transistor 2SC1971 blow up Adnan Al-ZADJALI replaced it with another 2SK3075. This transistor was more available and easier to get, and at the same time it also added a little more power, from 68 to 71 watt.

IC-7200 Band Voltage Modification
If you want to connect an external unit which can be controlled by the band voltatge from [ACC] connector, the modifihoneyion is necessary as in pdf attached.
The band voltage appears from pin 5 of [ACC] connector after modifihoneyion (1) is completed, or the regulated 8 V appears from pin 1 of [ACC] connector after modifihoneyion (2) is completed.

Performing this mod is the customer's responsibility. Icom does not guarantee this modifihoneyion's result.

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.

The following information was received from Wolf, ZS6AQC, concerning new Eproms for the PK-232 PAKRATT, plus a modification to eliminate noise from the op-amps. On recommendation of OM Piet, ZS6AQC I checked the noise in the power bus to the MC34074P op-amps and found (just like he said) that there is a lot of rubbish between the pins 4 and 11 of U23, 26, 28,30, 32 and 34. So, I placed some 1 microFarad caps across them and my receive noise is much less (measured on a mark=space scope cross display). In fact, I can now even copy some steady signals that don't even raise the S-meter needle. Hope you can improve yours also? This was received from OD5NG: he made this mod and results were outstanding.

Then Clark, W9CD made the modification and was pleased with the results. Consequently, I bought from Radio Shack 6 each 1 MF tantalum capacitors ("condensers" to Old Timers), and mounted them on the bottom of the board, with the shortest possible leads in the positions described above. The results are OUTSTANDING!!! RTTY signals I could not copy before are now perfect copy, even when you can barely see the traces on the scope. ARQ links, which could not be made before, now flow smoothly. The only thing I don't know if the mod will work if the latest version of the PK232 firmware upgrade is not installed, but I would think that it will. Give it a try and you will be pleasantly surprised.

P.S.: The part number for the referenced capacitors is:
Radio Shack # 272-1434, 1 MFD 35 Volts (Tantalum). Cost $ .59 each.

If you have one of these RS-232 to RS-485 converters (probably bought from E-BAY):
 Arduino rs-485 to rs-232 Converter

You will probably get a description like this:

* It is able to convert RS-232 signal to RS-485 balanced differential signal and extend the communihoneyion distance to 1.2km.
* It uses a particular pump to gain power from RS-232 signal (RTS, DTR, TXD) without initializing the RS-232 series interface.
* This interface converter does this without requiring any AC or DC power.

You will have problems with this converter from the arduino unless you read the spec sheet. Unfortunately the sellers will probably not give you the schematic or tell you how the circuit works.

I used this converter along with an arduino using the TX and RX TTL output to a MAX232 circuit, then this plugged directly into the RS-232 to RS-485 converter which in turn was connected to the power meter.

The response from the arduino was perfect. Not problems. But the power meter was not receiving the correct data.

The problem that the sellers don't tell you very clearly is what is needed to power the converter.

The trick here is to read this sentence a few times to understand it: "It uses a particular pump to gain power from RS-232 signal (RTS, DTR, TXD) without initializing the RS-232 series interface." So in order to get this RS-232 to RS-485 converter to work, you will need to hook the RS-232 serial port's DTR and RTS pins to the 5V Pin on the arduino (or another source if you have it), pin 5 of the serial port to Ground on Arduino, and the TX and RX from the Arduino to the corresponding pins 2 and 3 on the RS-232 port.

Pin 4 (DTR) - Jumper these two pins and hook to 5V from arduino
Pin 7 (RTS)

Once this is done, the RS-485 device will have enough power to send the correct data through.

*You could get around all of this by just purchasing a RS-485 plug in module for the arduino. It will save you a lot of time since these modules will convert the data for you without having to go to a TTL to RS-232 conversion, then to RS-485.

Hi, I developed a kit to replace the display board for the FT- 301D. No SMD were used and the kit can be assembled by a radio amateur in about an hour . The new display has, in addition to the frequency display, various advanced features. For example, the supply voltage of the FT- 301D can be measured or the band limits according IARU can be signaled. For disabled HAMs the displayed frequency and voltage is output in Morse code. With an IR remote control parameters can be changed. The software can be updated via the USB interface. A user manual is available on http://shop.elcon.ch/pd-1503415091.htm?defaultVariants=searc h0_EQ_Bausatz_AND_{EOL}&categoryId=1 . The selling price of the kit, depending on demand, is about $90 plus S&H. If you are interested, please write me to hb9gaa@arrl.net 73 de HB9GAA, Roland

New frequencies after the modification:
136-174 mhz RX/TX
400-480 mhz RX/TX

1. Open the upper shell (speaker)

2. Lithium battery located on the left side

3. Identify positive symbol on lithium battery

4. Remove resistance as shown in photos

5. Perform a CPU reset (page 61)

The software mod did not work at all. Then I initially cut the track leading from the resistor, without actually removing the resistor. This opened up the 1.2m band (220 Mhz, which was not available prior to cutting the track)but did not expand the other bands.

Later, I actually removed the resistor. This opened up the other bands, the 2 meter band now has a working bottom edge at 140 Mhz, everything (including ARS) works.

I suspect that the software mod would now also work, and I could change the country code as described in an earlier post, but I haven't bothered as there isn't anything in the 130 - 140 Mhz range I am currently interested in. If anyone has a similar experience and also tries changing the country code via the software mod I would be interested in hearing about the experience.

Yaesu FT-230R Problems
NO RF OUTPUT : The PA module is a common failure on this unit.

NO RF OUTPUT WHEN HOT : PA.

NO RF OUTPUT IN THE LOW POWER POSITION : Check the PA.

RF OUTPUT INTERMITTENTLY FALLS OFF : I have seen two or three cases where the PA has intermittently gone into oscillation. In both cases this was due to internal faults within the PA module. It should be noted that this oscillation can be sufficient to blank out a nearby TV, and this fault should be suspected if there is a complaint of TVI. It should also be noted that the PA continues to oscillate and draw current when returning to receive, and EVEN IF THE FRONT PANEL POWER SWITCH IS TURNED OFF.

NO AUDIO OUTPUT : Suspect Q07 - the audio o/p IC.

MUFFLED AUDIO ON RX : Note there is an internal tone control (VR1001) on the main PCB. A lot of people don't know it's there.

OFF FREQUENCY TX AND RX : If this is only slight then align the PLL. If the error is significant then the local osc xtal should be checked.

BADLY BROKEN UP ON TX+RX : Check X03 (5.76MHz) in the PLL.

ERRATIC TUNING : Tuning step switch.

144-148MHz OPERATION : On the micro board there are spaces for four small tinned copper wire links next to each other. In normal UK versions, two links, J1 and J4 are made. Cut J1.

S-METER READING FALLS OFF AS UNIT WARMS UP : See Yaesu mod sheet.

Still have my old SAR radios and pulled them out after years of being put away. Still work but I need a manual or someone who knows how to program them. I also need to know where I can get new batteries for them. I am doing mounted patrol work now and would like to have these with me in case we do a recovery or event.
Any help would be greatly appreciated.

I will be controlling a 12V Fan with a Raspberry Pi and a DS18B20 waterproof thermometer. The DS18B20 uses 3 wires even though they call it a 1wire system. The one wire is actually what makes the communication the other two is power and ground. I purchased the DS18B20 thermometer from ebay and they were pretty cheap. The DS18B20 thermometer was in a waterproof shell. The only problem I had which took me about 2 nights worth of playing around with the coding, the Raspberry Pi, and the 1wire DS18B20, was the wiring diagram that was on the Chinese seller's website of the DS18B20 stated that the yellow wire was ground and the green wire was the data line. This was wrong. Usually green is the common wire and I was a little skeptical at first but figured it was from China so anything is possible.

Of course, I didn't have any other 1wire devices to test on the Raspberry Pi. I couldn't test to make sure the Raspberry Pi was not functioning or the 1Wire DS18B20 was not functioning. Finally I took a chance and reversed the ground and data lines and it worked like a charm.

The 12V fan will also be controlled by the Raspberry Pi. A 555 timer will be used in conjunction with a digital potentiometer to adjust the fan speed.

Project pictures and circuit diagrams will follow.

The Rigol DS1052E 50MHz scope arrived and it has been sitting for about a year (I guess maybe it is out of the warranty now anyway, so time for the HACK!) We finally got around to hacking the 50MHz beast to 100MHz. The unit came shipped with 00.02.05 SP1 firmware. This was tricky because RIGOL knew about all of the hacking going on. They put a stop to downgrading the firmware with the 00.02.05 firmware version.

The only way to hack this unit is to downgrade it to the 00.02.02.02 firmware. This firmware allowed you to change the serial number and model number which changes the scope to 100MHz. To do this, you need to use a USB or Serial port with special commands. Any newer firmware than 00.02.02.02 supposedly removed this feature. The trick was to take the 00.02.02.02 firmware and change the header on the file to reflect a larger firmware version. RIGOL also obscured the firmware version in their new firmware (02.05) so it isn't as easy as changing the numbers intuitively. With the right combination and a hex editor, the firmware was patched to make the scope think that the firmware was newer, but in fact, it was the old 00.02.02.02 firmware! Nice hack that actually works!

Linux was not playing well with the serial port and USB port, so Windows was used to make the serial/model number changes. After wondering why Windows was only recognizing it as a hard drive, the option for "Computer" was found in the "I/O Setup" for "USB Device". Once that was changed to "Computer", Windows recognized the RIGOL unit and the numbers were able to be changed. I bet this was the only problem with Linux also. But the job is done and there is no need to go back to try Linux at this point.


I wonder if the hack actually increased their sales or lost them money due to everyone purchasing the same unit for half the price? I know the purchase of this particular unit was because it could be hacked to 100MHz so my opinion is they gained more business and publicity from it.

I had the same problem many people are having with the GeForce 7600 GT video cards. I had 2 x GeForce 7600 GT cards in the same machine (...running 4 monitors...). The 1500uF capacitors are all crap. They probably cheaped out on them when manufacturing. On one card I had 2 caps blown across the inductor. But I pulled all of the 1500uF 6.3V caps on the board and tested them all. ALL of them failed their leakage test. So the best thing to do on those is to replace them all. Even if they look good, replace them. The 1000uF 16V cap tested fine. Cards work great afterwards...

here it is I am sure a question you are shaking your heads at but oh well. Just purchased a Yaseau 767GX looks to be in good shape. Anyway Put it on an swl antenna I seem to be receiving beacons and so forth. The problem is when I first turned it on the VFO dial would move the radio thru about 1 mhz and then repeat. Now it wont move the readout at all I can use the up down button and tune thru the band but I am sure its way to course to find anything. Just need some help figureing out id the dial is OK and if so how to get it to tune. If not a suggestion for getting the radio gone thru so I can get on the air. Working on an antenna to be able to transmit

Extended RX/TX for Alinco DJ-162

1. Remove the battery pack. Remove the battery plate from the bottom of the radio.
2. Remove the back cover from the radio. This is a tedious process. You must take the knobs off the top and remove the top plate first.
3. Under the Battery clasp on the side of the radio (The little sliding thumb switch that keeps the battery from falling off the radio) you will find a yellow loop of wire. This loop is small and hard to get to. You will need a very small pair of cutters or scissors.

--Cut this wire.

4. Put the radio back together

5. Reset the radio. (You will lose your memories)

6. Go to the VFO mode.
Pressing the 'B' key on the keypad will now allow
you to cycle through the extended rx bands. It will cycle from 2 mtrs, am aircraft, to 800. The radio does NOT have the guts to receive 800. It just happens to be in the processor so don't waste your time listening.

7. This same jumper also opens extended transmit.

The new Alinco DJ-160 Radio will receive between 137-174 Mhz, and transmit in the 2Meter band only (144-148Mhz). A simple modifihoneyion to the radio will enable it to transmit in the full range it receives currently. I have not tested the output power on other frequencies (Due to my one and only watt meter getting fried) however I have tried setting a weather receiver a small distance away, and I did hear the radio in the receiver. To make the mod, the following must be done: (I assume that you have some experience with electronics and that you can tell a wire from a resistor, from a transistor)

1) Take the battery of the radio by lifting the battery release button. If you look at the bottom of the radio, there will be a metal plate that is held on with 4 small screws. Take this plate off, noting exactly how the clip was held on (like the slot for the battery release clip)

2) On the back of the radio there are two screws that hold the back of the radio on, take these screws out.

3) Now you should be able to lift the bottom part of the radio by the battery release button slightly apart. I was told that you should take the top knobs off, but I found that I didn't have to.

4) If you take the Battery Release Button and turn it about 90 degrees, the button should come out easily. After you get the small piece of plastic that is the button, you should see a yellow wire behind where the clip was.

5) Take a small wire cutter and CUT this YELLOW wire. You should probably make sure that the wire doesn't have bare metal showing from a lousy cutter, because I don't think that grounding this wire to the case would be HEALTHY for your radio. Smile

6) After You cut this wire. Assemble the radio, and just before you turn on the radio, do a power reset by holding the FUNC button while turning on the radio. This will reset the radio to ALL of the factory set parameters. YOU WILL LOOSE PROGRAMMED REQUENCIES that were programmed into the memory mode of the radio, so just write the frequencies down before proceeding with the above instructions.

7) The radio should be just like new, except that the transmit will be enabled for ALL frequencies! GOOD Luck!

If you use these mods for ILLEGAL purposes, pity upon thy sole, for you do not belong in the ranks of Amateur Radio. This
information is only supplied for Legal and Informational Purposes
only and I can NOT be held responsible for anything that you do with this INFO. And if you screw up your radio, TOO BAD. I can't be held responsible.
