I know practically nothing at all about xcvr internals but just wanted to throw out: T/R relay?

it would be too beautiful and simple if you could solve it as you suggested ....... a bit of optimism comes from the fact that the radio has 2 HF + V-UHF power amps and it seems impossible to me that

For WFD, a club member brought a club-owned TEN-TEC in because it wasn't putting out any power on TX. They hooked it up to some test equipment and started diagnostics. Indeed, there was no TX power

Did you try the radio with another antenna or dummy load? Also check your coax center conductor to the outer shell of your coax connector to see if you have a short. Good luck.. Best Regards Hanford R

No TX Power on all bands While tuning a V-UHF antenna the output power dropped to zero. Now by pressing the PTT, on all bands the transceiver absorbs approx. 500 mmA from the power supply. IF filters

Hai Thierry At present I can manage the disply of 857D but in a short time it needs replacement. So i am using the external display as a standby only. Thank you for your findings &3s and regards Unni

I am using 9600 but 38400 works also on my FT-857D (after changing need to switch off and on the radio). Anyway as Unni wrote and it is something I have never noticed because I always use cat display

Hi Steve, I can’t find the interface you mention on the page you sent. Can you send a link more specific? Thank you 73 Alex VK2PIR Sent: Tuesday, 25 January 2022 12:43 PM To: [email protected]

Mark Of course I was trying with 9600. This I will try and see how it works. Thanks a lot for the suggessition 73s regards Unni VU2TE

What cat speed are you using? I was using one of his catknobz with my FTDX10 and it seemed unresponsive until I changed it to?38400.

Try calling yaesu directly. When I did my radios they were cheaper that other places that where selling the display. That was in US though so EU and CA maybe different. Leonard K. Pennock (AD7AS)

Dear Thierry I am having one of the same ZL1CVD's disply. They are not that fast responsive with the changes and radio. I am using it but not satisfied 73s and regards VU2TE Unni [email protected]>

Yes Antoon. It is out of stock with Radio world. Will try some other alternatives. Thank you for the response 73s and regards Unni VU2TE wrote:
