Re: [wsjtgroup] Sound Card for Windows 7
- Hi Joe et al,
Thanks for all the comments and suggestions!
After much investigation of the various sound cards to make sure that I could find a
Windows 7 64 bit driver for it, I finally ordered an Asus Xonar D1 sound card, which
can be selected to sample at 44.1K/48K/96K or 192KHz @16/24 bit. I decided that
would give me the greatest flexibility for future use. I can use the 44.1K sample
rate for WSJT, the 96K for MAP65 or the 192 KHz with my LP-PAN. I still am not sure
what the suggested sample rate is for WSJT, but I assume that 24 bit will be best.
For now, I am going to try to get MAP65 going with my SDR-IQ and other Windows 7 64
bit computer (which has a Delta 44 Sound Card with a seemingly effective Windows 7
driver). I have not been able to get it to work yet, but I am sure it is just a
question of getting the software to recognize the correct place where the packets are
being sent from SDR-RADIO.
The new computer will be my main computer, and the one that I use now for logging,
rig control, WSJT, etc. But in the future it will have the capability to run the
functions from the other "monitor computer". I also currently use an E-Mu 0202 on my
main computer with my LP-PAN to provide a spectrum display with TRX-Manager (TRX-PAN)
and apparently there is a Windows 7 64 bit "beta" driver now available for that, so I
should be able to transfer that over to the new computer.
Thanks again for your help! VY 73, Lance
