[hpsdr] PowerSDR v 1.19.3.1.diversity2

[Joe Martin K5SO]

Hi Kurt,

The Firmware version for Mercury should be reporting 6.0 if you have  
loaded the firmware in the download package for PowerSDR  
v1.19.3.1.diversity2.  Mercury v6.0 firmware will run the PowerSDR  
v1.19.3.1 version and KD5TFDs version too.

However, the Tx OC PTT problem you (and I, now) observe doesn't seem  
to be associated with that at all.  The character of the problem  
pulses that appear on the Penelope J6 PIN 13 OC PTT line seem to be  
dependent upon the sample rate that is selected (192000, 96000, or  
48000 on the PowerSDR>Setup>Audio panel).  At 48000 Hz sample rate the  
pulses do appear much like a clock, hihi, but at 192000 Hz sample rate  
the spurious pulses are much fewer in number and much narrower in  
width, at least on my system.   Looks like maybe a timing problem in  
the USB comm link to me.

I do not see any such pulses on the PTT line when I run the W5WC  
PowerSDR v1.19.3.1 program and activate the PTT line so the issue is  
certainly due to my diversity Rx mod code additions somehow (maybe  
indirectly, actually).  Perhaps the extra processing time is creating  
some kind of timing problem and some tweaking of the buffer sizes may  
need to be done.  The xmit audio sounds fine here even when the PTT   
line pulses are present.

I'll stay on it until I figure it out and get it working properly.

Thanks again for the feedback!

73,  Joe K5SO
