Kit told me something I didn't know about the allocation of callsigns for APRS stations in the UK.
- All APRS station callsigns start with MB7U (for Unconnected, I would guess.)
- A single letter following the U denotes a digipeater (e.g. our local digi MB7UQ)
- Two letters following the U denote an iGate.
I hope Kit's new iGate will soon spark some activity in the Aberdeen area which up until now has been pretty much an APRS desert.
