John: Well I knew it was something stupid - I had the carrier set at 1500
instead of 1000 Hz on the server. It should have twigged when I saw the
red cursor bars 500 Hz higher than the RX signal. With the strong test
signal I suppose the software detected enough signal on the edge to lock
into it sporadically. Now for the real world test - I'm going camping this
weekend about 75 Km from the server.

Server Software: Fldigi 3.20.28, Pskmail 1.0.3
Client: Fldigi 3.20.19, jPskmail 0.5.2

Thanks for the pointers and sorry for the trouble.

server), that the fldigi applications can exchange data properly. There
are a few macros in Fldigi that you can use to test that like a CQ. If
this does not work it means there is an issue at the sound system or
between the PC and the radio most likely.

check on both fldigis (the client and the server) that the ping frame is
received as it is sent. For that, check what is between the <SOH> and
the <EOT>. It should be for your call sign: "<SOH>00uVE6UQ:7 3C1A<EOT>".
