[hpsdr] PTT and CW with Penelope

[Roger Rehr]

Thanks Willi!

I will give your suggestion a try.  I am sure the DB-25 on Ozy will  
work for PTT, as you recommend.

The CW works fine for me; I was already using the DB-9 connector for  
it as you recommend.

My point is just that the PTT connection on Penelope does not work as  
it should in CW mode, at least for me, and unless I am doing something  
wrong, others will be adversely affected when they go to use the PTT  
connection on Penelope for PTT in CW mode.  Since the PTT on Penelope  
works fine in voice modes, and since it works in CW mode with other  
PowerSDR/hardware configurations it would seem to possibly be a  
software or firmware error that may be correctable.  While the Ozy  
connection is a 'work-around', it would be nice to be able to use the  
PTT connector on Penelope as one would expect to be able to use it.

Also, I would just prefer not to have to rewire 5 nicely done HPSDR  
cables because of a coding error, if one exists and if it can be  
corrected.  Things look so nice at present, and won't look as nice if  
I have to rework the cables  ;)

Thanks again,

Roger Rehr
