The most common reason for Q121 to blow out is that R122 was often stuffed with a 4.7k resistor instead of 2.2k, which forces the VGS of Q121 to about 4 VOLTS all the time! That makes it dissipate almost 2 watts continuously. The fix is to either pull the board out and change R122 to 2.2k, or, to simply add a 4.7k resistor from the gate of Q121 to ground, which brings the bias down to around 2 volts, and the idle power down to under 200mW. Lowering the power via the menu on the radio will not change the idle power! You can measure the Vg to ground on Q121 to see if your radio has the issue. If you read around 4V, you need to fix it ASAP. So many IC-706MKIIG are just about to fail due to this error. I will post a video shortly on the details, but the fix is simple and can be done by anyone with a little soldering experience. 73 and great video! de W6EL

Great video and radio. Only problem I've had is VERY intermittent receive being very weak on 2 meter ssb. I think it might also happen on fm, but it's been a long time since I've used this radio on 2 meter fm so I don't remember. It's never been frequent enough to warrant taking it apart and quickly goes away when you quickly key the mike a couple of times. I love the vfd display on the LP-100A. Looks like a nice piece of test equipment. Best regards.

Coming to this very late in the day! However an excellent description showing how to replace the burnt out pre-driver driver FET Q121 in the the 706mk 2 g. It would have helped me if I'd seen this before same fault occured in my 706 (s/n 16566) after many years of good service I inadvertantly left it on TX for half an hour it failed. After replacing the FET the fault occured again but only after a short period of TX (Q121's relies on the PCB as a heat sink which it seems is less effective if the PCB is burnt) . The problem appears to be due to R122 in the gate bias circuit of Q121 being factory fitted with a 4.7k resistor instead of the correct value as shown in the circuit diagram & parts list as 2.2k . This sets the bias at about 4v instead of 2v. Q121 then draws too much current eventully fails out if left on TX for too long. Other 706 owners have it seems had the same fault. Were only706's from a batch affected or does it apply to all Mk2g's ? I believe that some 703's may have had a similar fault. 73... Ken G3LVP

Good outcome on a job that many technicians would probably not touch. Burnt PCB, dubious components, evaporated traces. Not a good start! My question would be why that pre-driver FET suddenly went short circuit. Your guess that the 5.6 R was incorrectly labelled was a good one, and if that source resistor had been 5.6k the maximum current through the resistor would have been 2 mA but as it is 5.6R, the current is over 2 amps and power dissipated in the resistor would be almost 30 watts, no wonder things got (too) hot! 73 Andrew VK1DA.

Hi Peter...I think its Peter, most interesting video and good to see you get the radio working. I've just done similar repairs but my damage was much worse!....L232 supplies 13.7 Volts to the VHF/UHF Power FET because this draws 12 Amps at full power it gets pretty hot...its taken over 10 years but just last week this connection into the PCB was slowly breaking down to finally result in a small electrical fire that created a 6 mm hole right through the PCB!....I had to use Solder Wick Braid to replace damage tracks, I've only just placed power on and all seems okay albeit the power appears a little low on VHF. I lost a small ceramic SMT capacitor that sits just under L232 between ground and the Drain of Q231 but its not shown on the parts layout diagram on page 59 of the Service Manual. In your video I could see the capacitor was fitted, I wonder if you might have information that indicates what its value is and or its circuit reference?....CheersClint - VK3CSJMelbourne

KD0CAC Hi John, well that is not so complicated. In this case it was enough copper left, so I cleaned the pat that we can solder again on it. Then solder the component first and then put a drop super glue to the pad that's it. If the damage is bigger you take copper foil cut it out like you need it and glue it on the board. Carefully do the through connections and after that put the new component on.. Hope that helps a bit.. Thanks for comment 73 Peter

This problem ive seen before..i burnt out on of my 706's just like this one but with more severe damage than meant the board was not repairable..burnt boards are sometimes resistive, carbon conducts and worse at RF , so even if the track is at the correct resistance to ground via resistors, it could have serious problems at RF frequencies. one has to ask why the pre driver gets so hot that it burns its tracks and fails in the first place.. ive had 5, 706's and they are great radios, cooling is a major issue, the internal fan mod, that we did even on new radios was to add a resistor to the switchable fan supply ( that increases cooling during transmit ) direct to the 12v supply (13.8v) so that the fan runs a little faster all the time and keeps the radio cooler. I even did a 2nd upgrade to my current radio last year during a heatwave as shack temperatures were so high i decided to increase the air flow.. by reducing the resistor value further to increase fan speed.. this mod is recommended for many small high power radios where cooling is critical. I've repaired boards by inserting a new section having cut out the burnt section and making a copy section from another board , de populated to be able to photocopy and etch a replacement section. not an easy task but its been done with success. having a good section of PCB under the components is necessary to assure sufficient cooling and heat dissipation after the repair. Thicker copper plated boards are better for heat transfer and rebuilding burnt tracks with better boards is recommended. good repair..

really discouraged with icom. i literally order approx $22,000 a year in gear with the icom name on it ... i order from gigaparts which is excellent... one time i have a problem and icom will not stand behind it .. i order 2 icom 718 radios at a time, one time recently i get a case that is dented, " not the box the case" so i know it happened at icom , i do not blame it on gigaparts, there is no way it happened at gigaparts, it happened at the factory . was told i had to purchase a new case lid for $36.00 .. nice staff at icom but when it comes to customer service i am really truly disappointed. over not making it right they are willing to lose a customer that spends so much money on their product. .amazing......Attn icom. This will be posted in every area of the web i can find to copy and paste..

Do I hear a Dutch accent or should I say German accent. They are both similar but not the same.

Hi sir, my Icom IC 706MKIIG doesn't power. When I switch it on, I can only hear clicking sound. Any suggestion sir. I am Florence Selvestian (9W6AI) from Kota Kinabalu, Sabah (North Borneo) Malaysia

Just curious if it is possible to courier to you to be repaired. Thanks very much

I had the same problem - sent it for repair - was a pc board trace, eaten away by adhesive. Not a big problem. It prevents proper voltage and causes the power cycling/clicking of relays. It's a known issue, and may be what you're experiencing.
