[hpsdr] Hermes Initial results and TX Question

[Joe Giacobello, K2XX]

Thanks for the info, Tim and Ken.  I found the info on the DJ6AY (Gerd) 
switch in the wiki, but his Ebay sales no longer seem to be active.  I 
wrote directly to W9KFB and he is no longer affiliated with Gerd.  I 
have sent DJ6AY an e-mail via Ebay and am awaiting a reply.

If Gerd is no longer is supplying and unless someone has some better 
ideas, it seems like it might be necessary to build an external switch 
with a 5V PCB relay powered from the Hermes and activated by its PTT.  
If one upgrades the Hermes with the ANAN 10, do separate RX and TX ports 
become a non-issue?  I would like to try the Hermes as a QRPp 
transceiver with my existing antennas.

Regarding the PowerSDR temporary freezes, I did see the reference to 
DPCs in the VK6APH manual.  I haven't downloaded the diagnostic software 
yet, but I did stumble across a diagnostic tool in Win-7 that showed 
that there are indeed DPCs.  The problem seemed far less frequent after 
I upgraded to PSDR 2.5.5.

I am waiting to receive an Ethernet switch.  So I currently use a direct 
connection to my PC from the Hermes.  There is no wireless or second NIC 
card.  I can confirm, however, that communication between Hermes and the 
PC does not work if one just uses a hub.:-[

Thanks, again, for your help.

73, Joe
