Re: [Flexradio] Radio locks up when pressing the TUN button

[Gary Warner]

Tim,

Thanks for the quick response.

I was trying to tune through my Palstar AT2K manual tuner.   You are 
correct that it does not lock up when using the internal tuner.   I 
wonder why that particular combination of frequency and power caused it 
to lock up when just a few kilohertz away it worked fine?   I assume 
that your recommendation for power is anything less than the power that 
locks it up?

The reason higher power levels are allowed when tuning is some 
external ATUs and amps need more than 10 watts.


We also use TUNe at 100 watts into a dummy load to verify the PA 
maximum output without have to hook up a key in CW mode to do it.

I am running a Flex 3000.   I was at 28.457 and trying to tune up the 
radio to my antenna with my tuner.   I had just tuned successfully 
just a little off this frequency and was just touching up the tune.   
I pressed the TUN button in Power SDR, and it totally locked up and 
continued to transmit.   The only way I could make it stop was to use 
ALT-F4 to close Power SDR (version 2.2.3), or to turn off the radio, 
which, of course, crashes Power SDR.   I tried changing the 
frequency, and it worked flawlessly on all other bands, and also on 
this band without any lockup, EXCEPT between 28.4558 and 28.4575 
where it consistently locked up Power SDR.


I finally tried reducing the tune power from the 50 watts my copy of 
Power SDR to 10 watts, and it seems to have made the problem go 
away.   I do not recall changing the default tune power to 50 watts, 
and now wonder why it is variable if it can cause Power SDR to lock 
up.   I see that the screen capture in the manual shows it set at 10 
watts, but why is it allowed to be changed?What else is TUN used 
for?
