Tnx Bob! Once I thought I had figured that out yesterday I had a nice qso with a cuban on 40m psk using the vac. Very nice job indeed and the audio seems cleaner than from the hardware soundcard I was using.
One bit of suggestion I made when speaking with Eric (I call him "E" now). Would be great to have a control over the audio chain to and from the VAC independant of the AF control on the SDR. Right now, you have to adjust the AF to get the correct input level to the external program (MixW in this case). Having independent control over the audio would be able to optimize bothe rx and tx from the VAC without screwing around with the AF controls. Will also ensure a clean tx signal as you can adjust to match the output set on the radio and the drop it down just a bit so that you don't overdrive. Tnx agn for all you do....this BUD i'm drinking is for you.....BTW...it's a nice cold one! :) 73 Greg AB7R -----Original Message----- From: Robert McGwier [mailto:[EMAIL PROTECTED] Sent: Thursday, November 03, 2005 7:44 PM To: ab7r Cc: Joe - AB1DO; Flexradio@flex-radio.biz Subject: Re: [Flexradio] virtual audio cable issue Good point and it reveals an interaction between the various settings. If you choose 2048 on VAC and it is 8000 samples per second, this is turned into 12234 samples when resampled to 48000. If you get the phasing wrong (it will be random, having nothing to do with you personally) you could get unlucky and need to deal with numbers of samples in excess of 16384 in the ring buffers and that would do you in. The ring buffers are 16384 samples. I would use the smallest buffers for VAC that will work and we should make 512 the default. Bob ab7r wrote: >Thanks Joe, but that's not it.
