Hi Guys
I am getting the attached amplifier message when attempting to tune up on HF

experttune.jpg


EESDR says the radio temperature is 39c, and the fan is not even on. This only occurs on HF
Works as expected on 2m

Running 1.3.1 Update 6

Hello Rome

This now seems to be a hardware issue. I rolled back to Update 5 and it is the same. Every time i try to TX on HF it happens, switches off TX and there is a hissing sound from the radio. I have only just purchased this radio, and have contacted the dealer in UK to resolve issue

Hi, please don't rush it, we'll prepare an Update 7 next week, please check it out and let us know the result.
We suppose it might be related to the firmware.

Could you please make a short video of the issue, when it happens, what temperature level at the moment, and send it to us.

Hello Rome

I have attached a short video to show what happens. This is on all HF bands, VHF is fine. You can see that the temperature of the radio is 38C.

Hi,
Could you please try this test version of the software. Let it update firmware and then test it.

Hello Rome
Software installed and firmware updated, but the same result - see attached pictures - is this a hardware issue?

Regards
Charlie

In case we won't be able to help you on a firmware/software level, TRX either will be repaired a swapped for a new one.
