ANAN200D problem

Postby F4EGA » Sun Jun 20, 2021 9:46 pm

Hi all,
I had not used this tx for a little while and this morning I decided to turn it on, strangely I had half power, I tested on all bands and on a dummy load, for a tune at 100w i have 50w on all bands.
I reset the database but without success, the problem is the same.
Do you have any idea where this could come from?

Hi Patrick
I have had this happen on my 200D before. If you haven't done so already it is best to update to the latest Thetis (v 2.8.11) and firmware (Orion v 1.9). Possibly you may need to reset the gains in PA Settings tab to give the correct power output on each band.

Hi Dave,

I have been using thetis 2.8.11 since its release with Orion 1.9.

Everything worked well so far and overnight the power is divided by 2 !!

I recalibrated the PA but it's the same.

Hi Patrick
If it is not firmware or Thetis then maybe you could look at your PSU to check that the voltage is correct and that power cable connections to the rig are not limiting current on TX. Check your current at 100 drive if you have a meter on your PSU. I see 16A on 20m to give 100W out with a gain setting of 47.9. It is strange that it is half power on all bands. If you increase the gain (actually decrease the spinner value) do you see an increase in power?

Bingo Dave!!

My mistake, the voltage button has been moved and the voltage output was only 9V!!

Now with 13,8V all is ok!!

Thank you so much!
