Matt, well sorry to hear that they are no longer supporting those parts for the 857 as I have 3 of them. If you are having problems with yours's I would try one of the crystal-controlled ones as I use

It seems like the 2 470 ohm resistors right after J1025 PIN 7 and PIN 8 where blown. I replaced them and now everything is working normal again. Not quite sure, why MIC DWN was pulled down to 0V, but

In case anyone has the same problem: My buttons aren't working, because MIC-DN (PIN 8 on J1025 / PIN 3 on J1010) gets pulled down permanently somehow. There should be 5V when there is no button

Hi Troy, Unfortunately, Yaesu stopped selling the TCXO-9 quite a while ago, and new inventory at the various radio suppliers was depleted long ago. 73s Matt VE3MXG

Yaesu would most Lickly your best bet for an original replacement. Troy KE4SKA FYI: I have 3 of the clones in 3 different radios and have had no problems.

Hi Giulliano, Thank you for replying. Unfortunately, I do not have a TCXO-9 to rework or adjust.? I am looking for my first TCXO-9 for the FT-857D. I have heard of the issues with the clones.? I

Matt, I experienced in the past the tcxo failed to oscillate due to component aging. I corrected the issue adding a smd resistor at emitter of oscillator transistor, doubling the bias

Hi All, I am looking for a TCXO-9 for my FT-857D (used original TCXO-9, not a third party copy).? If you have one for sale please let me know. 73s Matt

Yes right , in DB9 case there is plenty of place for components …. after that use an USB/ RS232 convertor having all command pins for RS232 ( not only RX and TX ) Good luck Dan

Dan-san, I’ll try the schematic. One NPN TR and one resistor can be set in the DB9 connector case, I guess. Thanks a lot. // HIRO, JJ1FXF

Not insured. I am now out of balance as an Emcom guy. I had two FT-857D radios. One for portable. One for car. A FT-897D for the home QTH. I keep waiting for a new 100W all mode all band shack in the

?Hope you'll get this b* and kick his teeth him !!! fingers crossed my friend, Thierry

Very sorry to hear this. Was it insured? Peter G0LQU Keith wrote:

Hi, I used in the past this simple solution: http://www.ok1ti.cz/w-rigmanuals/yaesu/ft817/FT-817-FT-857-FT-897%20Interface%20for%20CAT%20and%20Audio.htm 73. Dan, yo3gh

Does anyone know where I can find a specific schematic for USB-Serial/CW-Key Interface for FT-857? I would like to send Morse code from PC via USB-Serial RTS/DTR. Thanks in advance. // HIRO,

Thank you for the suggestions, but unfortunately it's not the lock key. The lock button is also not working and there is no lock symbol on the display.

Have you tried the lock button on the lower right side of the panel? -- Leonard K. Pennock (AD7AS)

Could it just have the Front Panel locked out with the Lockout key? If you see a small key icon bottom right of the display press the bottom right button to the right of the large tuning knob to turn
