Hi Rein, I guess there must be a misconfigured server somewhere then.

Regarding the audio glitch, when I look at the playback stream from jpskmail in Pulse Audio Volume Controller I can see the audio glitch that kicks the vox in the signalink. It doesn't seem to happen with fldigi or wsjtx. The glitch occurs about 1 second after the end of the outgoing waveform.

I'll see if I can reproduce it on the laptop that I was using previously.

Hi Darren,
the N0CAL comes from an Igate which has not yet been configured.
A solid tone with the duration of a frame normally comes from fldigi

I don't have any audio problems with jPSKmail V1 (with fldigi) or V2.
Can you hear it in your headphone when you transmit?
Maybe an audio configuration problem somewhere? Does fldigi do it right?

I think there might be a pskmail server or something else responding to
my pings and beacons with a carrier, about 100Hz below the centre
frequency on 10.148MHz. The duration of the carrier is consistent with
the length of a data frame and it seems to start very swiftly after my
transmission ends. I don't know if this is related to the station that
is igating my beacons with a NOCAL in the path. I don't think there's
any other response to my pings at the moment.

My other issue is a quirk whereby there is a short unexpected
transmission of some audio that causes the SignalinkUSB's vox to twitch
the PTT line to my radio. This is sure to interrupt any immediate
response from a server. This seems to happen with both the 2.0.33 and
the 2.1.0-i jar I just downloaded. This is all running on a fairly new
linux box, not the laptop which on which I've previously been running
the jpskmail client. I've tried other progs such as fldigi, and they
don't seem to generate this audio artifact that causes the rig to key up
a second time.

Has anyone alse had any similar experiences?
