Hi Joe and All,
I have checked JT65-HF 1.0.9.3 and JT65-HF HB9HQX v2.0 TX audio using virtual
audio cable and r6404 for RX.
JT65-HF 1.0.9.3 in my setup transmits dirty signal with the multiple glitches.
JT65-HF HB9HQX v2.0 has mostly clean signal, but small spectrum spike at the
end of tran

No. Most definitely, audio glitches are NOT usual behavior when WSJT-X

That's a good one to check...along with looking at DPC Latency and ensuring
background process have priority.
I'll let you know what we find.

Hi Mike & all,
another cause of audio glitches is USB hubs. The USB audio streaming

Hi Mike,
you need to do Joe's test or similar. You can do this:
Set the following on the transceiver:
• Mode: CW
• AF control: Center
• Menu No. 34 (CW RX pitch): 800 Hz
• SHIFT control: 800 Hz
• RIT function: OFF
• Break-in function (V
Looks like he's got some 1kHz interval birdies in his audio chain
(RigBlaster).
He only has about 2500Hz bandwidth so it's not from the rig.
He has a TS-590S
I worked with him some more...he has a dual-core dual-monitor with 4gig
memory and it seemed a little stressed out.
So I bumped up wsjtx to

Another thing of note is a strong peak at 4kHz on the last file but no
sign of that on the f

In addition to the discontinuities I hear a buzzing noise on the signals
and I would get him to check the physical audio connections. It may
I didn't think to check his system for CPU usage or such. He's using a
RigBlaster.
A test procedure would very nice Joe

Helping out somebody and he seems to have periodic problems decoding.
These 3 wav files don't decode at all.
He does have good time sync
He does have 48kHz sampling.
Apparently things go well for him for a while and then decoding fails. So
there has to be something funky with the audio here that
