Re: Best AGC for digital modes?

I use VMP and the Behringer 202HD and see almost the same numbers as Tony. I actually see 60db under the same conditions you just described Scott. I think this is just a difference in gain in JTDX vs. WSJT. I frequently decode all the way down to -26db signals and work them with JTDX so I know the s...

Re: Angelia (ANAN-100D) Protocol 2 test pilots: please check in

Hi Gary, I wonder which way you adjusted your bias to improve the IMD? I found that by increasing the bias on the PA in my Anan some time ago the IMD without PS running improved from the -20's to the -30's. This also resulted in an improvement with PS running. If I recall correctly, I changed the bi...

Re: Resampler Adjustment

Hi Brent, I've also been working with Thetis and playing with VAC. What I have found so far that works at a setting of 192k is a buffer size of 256, port audio both set to manual and zero, and both ringbuffer settings of manual and at 25. This seems very stable with quite a lot of other things runni...

Re: Diversity Operations

I tried out the diversity option on Thetis 2.6.4 last night on 160m and it seemed to me to be easier to find the null than Protocol 1 versions. I did notice an anomaly though. Several times, when I had nulled out interference, I found if I pressed the Disable button to disable diversity then pressed...

Re: Protocol two across a LAN

Joe, next time it happens, if you haven't before, make sure you not only power down but also turn off the power switch on the computer power supply for about 30 seconds. Just shutting the system down doesn't kill all the voltage to the motherboard.

My 160m USB, 2.7khz daytime noise level with the meter on sig avg runs -107/108dbm on my RX antenna system. The gnarly spur is around -98 for this mode and bandwidth so it is easily heard as it is about 10db above the noise level. Fortunately, my spur is out of the band so it doesn't matter to me. I...

Re: Unstable, wide, nasty spur

I use an 8000 board and I have exactly the same spurs you show; the large gnarly one is at 2.0 mhz on my 8000 and the two smaller ones are exactly where yours are so if there is something defective with your 7000 it is also defective with my 8000.

Hi Larry,

I've never used MicroSoft Sound Mapper but I just opened Audio-Vac1 and set the Driver to MME and then looked at both the input and output and see the "Microsoft Sound Mapper" option for both. Don't know why you wouldn't see it too. I'm using PowerSDR version 3.4.9.

Hi Conrad,

It happens with the 8000. That is the board I use. Perhaps it is more difficult to hear on HF due to the higher noise thresholds.
