On the APRS tab you find the togglers for Beacon and Autolink.
When both are OFF jpskmail will not transmit.

Have you tried IS0GRB-3/SM0RWO on 10147?

I can hear IS0GRB-3 until 22:00 UTC, but 5W is too little to work on 30m in the 
Have you tried to use DA5UWG on 80 meters? VK2ETA uses THOR22/THOR11 in the 
evening on 80,
PSK modes have problems there because of Doppler and multipath resulting in 
deep QSB.
I am living near Eindhoven airport, and when a plane starts I cannot use 
PSK500. PSK500R has a 
lot less problems with that.

The server is OH9RHF. Unfortunately it is listening on PSk250, PSK250R would be 
a lot better for QRP.
You can use modes like MFSK16 or THOR11 on the multispeed servers on 10147. 
With jpskmail- RSID 
TX will be on automatically while sending a beacon.

Problem is that the Intermar servers on 10148 are not (yet?) using FEC. The 
servers on 10147 running PSK500R are less 
sensitive to QRM/QRN. We are also thinking about asymmetrical mode operation, 
where QRP stations can 
transmit on a narrow mode while the server uses e.g. PSK500R/PSK500. This will 
take some time though...
