Re: FT857D No TX Power on all bands

 

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

?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 can't be because they were replaced 3 years ago and then they don't produce this symptom.

Please suggest me some solutions

Re: FT857D No TX Power on all bands

 

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 both are burned at the same time. it is much more likely that the pre drive driving both power amplifiers has burned out.

So I appeal to all owners of this radio who know of this rare problem.

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 out on the expected frequency.

After trying many things, someone finally realized that the radio was in split mode. It was transmitting on the VFO-B frequency. The TEN-TEC display simply wasn't definitive enough to make it perfectly apparent to people who weren't used to operating it.

Sometimes it's the easy solutions... just sharing this story in case you haven't verified that the radio isn't operating in split mode.

Not sure of your online shopping access but below are two options/links. The first link is to a guy who refurbishes FT-857 control heads (all with original Yeasu parts too). If you are more adventurous DIYer, the second link is to order an Yeasu FT-857 replacement screen so you can do?the repair yourself.? There are several YouTube videos out there on doing the repair yourself.? Hope this helps and good luck.
