[hpsdr] A state of shock.

[Jeff Cook]

Dear All,

I am in a state of shock and feel bereft, my beloved HPSDR is not 
working correctly.  I had it running for about half an hour earlier on 
today when suddenly it switched into TX mode and then back to RX, it did 
this several times intermittently over a period of about one minute and 
then stayed locked in TX.  Clicking the MOX button on PowerSDR does 
nothing and the software shows that the hardware is indeed in TX mode.  
I removed the microphone lead and replaced the USB cable that joins OZY 
to the computer but to no avail.

I have found that by going into PowerSDR Setup and into Options, that by 
placing a tick in the Disable PTT box I can then switch the unit out of 
TX by pressing the MOX button, and like this the unit transmit and 
receive is normal.  However of course I lose the ability to switch into 
TX mode via CAT Control.

HPSDR will not function at all when attempting to control using the Kiss 
Konsole, I assume that this therefore rules out a software problem and 
means that I have a hardware fault.

Any help you can offer me in fault finding would be greatly appreciated, 
I have to admit that I don't really know where to start, I can only 
guess that the PTT circuitry that is initiated via Cat Control has 
developed a fault.  I have the Pinocchio extender panel, I knew there 
was some reason for buying it!

Thank you.
