I have one of these: https://picclick.com/Yaesu-TCXO-9-High-Stability-Crystal-for-FT-897-FT-857-201488442119.html Of late my FT-897 has been drifting off enough to be annoying on SSB and probably

Have you tried to clean the relays? To perform the Relay Cleaning Procedure: Power down the radio. Hold both the [BAND UP] button and [BAND DWN] button (Buttons #12) simultaneously while turning on

Right, it's the same path I want to take. The forum has reached its limit. jeter.d.barron@...> ha scritto:

If the full factory reset does not get you going I believe you will have to actuallyt open the radio up and troubleshoot. The TX indication shows me that you are getting into the transmit mode and you

Do a master reset! Here's how: To perform the master reset: *Hold the [HOME] button (Button #4) while turning on the rig with the POWER button (Button #10)*. The radio will be reset to factory default

This is a long shot, but I've had several issues of the the years with radios receiving but not putting out an RF power due to poor power cord connections.? In some cases at the power supply because

this may also be an option, but the relay switching noise is heard. Both from the PTT on the microphone, and from the PTT on the device

correct colleague, I too am almost convinced of this. the power amplifier will be in order but it is not receiving power. Unfortunately, I am not a technician and I do not have the necessary equipment

Unfortunately, no carrier starts: When I press the PTT the red TX / BUSY light turns on and the fan starts, and I repeat it does not absorb any current from the power supply. Tested in all TX modes:

Is it possible it was bumped into SSB mode and won't transmit until you talk? Randy (KE5EOT) ARRL, QCWA, ARES, RACES, ROWH http://ke5eot.webs.com

If 500mA at tx is confirmed the tx chain has not power supply or tx bias. Start digging from this fact.

A very good question above was if the transmit indication was being activated. If the transmit indicator is not showing transmit mode then the problem could be in the PPT circuits either mike or

Is there anything plugged into the CAT or DATA ports on the rear? If so remove them and re test. I have seen where a Tiny Trak 4 was connected to my FT 857D and it stopped the PTT on the mic from

Apologies in advance if this was already checked. Does the radio show red light for transmit, and what mode are you using? Only CW, PKT, or FM will transmit a carrier without modulating like speaking

No TX on all bands and the receiver works OK on all bands means that there will have to be some troubleshooting involved. First try a factor reset to see if something has been miss-set. After this you

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
