[digitalradio] CMSK successful tests on 600m

[zl1bpu]

I ran 200W of CMSK8 for two hours last night, with 100% copy at VK2DDI (2200km 
range) and good copy with very deep fades at ZL2AFP (500km range). Copy was 
good in VK2 well before sunset.

Later in the evening a test with 50W of CMSK63 was also 100% copy for long 
periods at both locations.

The transmissions were on 508.150kHz. I used a Redifon DU505 exciter. The 
transmitter is Class D H-bridge and the antenna a base loaded inverted L with 
7.5m upwire, and three 30m top wires.

Both receiving stations used PA0RDT mini-whip antennas.
