Thank you, this helped me greatly to get RX back on frequency. Now, do you know what tuning capacitor to adjust to make a fine adjustment on TX?

Hi. My encoder is all floppy. It has never frozen the display yet. Have you had any luck finding a suitable replacement encoder?

I think signal intelligibility on the 235 is better

Great video and explaination. Thank you. I have FT-757GX and it JUMPS frequency about 500 cycles back and forth and looks to be off frequency on 10 meters. Thank you for this great video.

A bad contact due the oxidisation is a typical problem not only in FT-757GX, but in many old models. Some of them works well after only a few triming moves, some need a chemical cleaning with "Contaclean" or other similar spray, depending a capacitor type. Few years ago I replaced a 3 trimming capacitors in a FT-767GX because they were uncleanable.

This helped me quickly repair my FT-757 GX II. Thanks so much for supplying your troubleshooting knowledge to save others a ton of time!

Why do you not use internal generator 25khz on cw-n and s-meter level? It will be easier to drive.

@inboxpm 10 ай бұрын

FT-757GX have a digitally controlled PLL, working from one reference oscillator. This model have no internal calibrator. Only an older radios with mechanical VFOs have them. And need check and trimming with the same method.

Ok, but you can try nanovna stimulus-start 14mhz-stop 14mhz generator on radio input with ATT ON. Work good for me.@@inboxpm

Hello from Australia Prakash I have exactly this problem with my yaesu and wonder can you help with part numbers of the modern components you used for the repair :) thank you sir

@prakashsmg Жыл бұрын

Dear Matt, Good day, Pls Try 2 actions: 1) Replace all Existing Tantalum Capacitors on PA Unit with any brand Electrolytic Capacitors 10mfd 35V or above. And try Power On Rig, if did not work, you need to check Relay coil & power supply circuit for Power On Relay operation. 2) For Power On Relay function circuit the components you need to check and replace are a) Q10 Transistor 2SD892R or any simple NPN transistor can work. b) D10 & D12 Diodes Si 1S1555 or use any high speed Diodes 1N 4148 The second action may not be require for many cases. Download FT757GX Service Manuel from web. Good luck & feel free for any other info on [email protected] 73 de VU2KPU Prakash.

@@prakashsmg thanks very much prakash I will dl the service manual and try the above advice, I did not realize we can swap the tantalum for electrolytic! It may be a while before I get to this but will write back once I have tried everything 😃 thank you sir

What voltage are the original bulbs? Did you put your own resistors on the LEDs, or did you buy voltage-specific LEDs?

@prakashsmg 2 жыл бұрын

Old bulbs are 12V. For LEDs resistor used in series.

@Francois_Dupont Жыл бұрын

V=RI it is the most basic stuff.

@teulis Жыл бұрын

I just did this same mod on mine, used 3v leds, with a 470 ohm resistor in series, worked very nicely!! Original lights ran at the same voltage as the radio, 12-13.8 or whatever your input is.
