[Trlog] SBDVP question

[Charlie Ocker]

I'm trying to get TR and SBDVP up and running.  Built and tested the 
N4ZR "Simplest Sound Card Interface" (tnx, Pete!) and it seems to work 
FB.  My question is:

Does using SBDVP with the PTT option (-p1 in my case) preclude full 
duplex operation?

I'm getting inconsistent behavior in my test setup.  I have a 
SoundBlaster compatable sound card (ASound PCI Express AA-1815).  I have 
the BIOS setup for "plug and play", as this system is a dual boot 
Linux/DOS.  The sound card appears to configure correctly upon boot 
judging by the messages it sends out.

My test setup is using a footswitch for PTT via the mic jack, and TR 
controlled PTT via back panel (PTT in parallel).  PTT works fine in CW, 
but *sometimes* it works in SSB when playing back DVP messages, and 
*sometimes* it doesn't.  Also, after loading DVP messages in TR, exiting 
TR, then unloading SBDVP via -u option; I see the DVP messages written 
to disk, but when starting TR again (first doing SBDVP -p1), I cannot 
play the previously recorded DVP messages.

Any ideas?

Thanks es 73,
