The 2m 'multispeed' gateway HB9AK-1, that is offering packet radio access to the WINLINK network with different modulations and speeds (AFSK 1200 Bd, BPSK 1200 Bd, BPSK 2400 Bd, QPSK 2400 bps, QPSK 3600 bps) has now added VARA FM (both 1200 and 9600) as additional modes of operation. The gateway listens in all modes for connect requests and answers in the respective mode. VARA FM (9600) reaches a throughput of up to 80 kBytes/min, a more than ten fold increase compared to conventional packet AFSK1200.
For over a year an elusive noise floor of 15 to 20 prevented any real use on 80 and 40 meters.
A bad power supply was located and replaced.
Noise on 80 and 40 now usable for RX.
XE1VP is in the city so 80 meters still a bit high, but will see how it goes.
