http://www.pskmail.com You probably hear DK4XI-80. The mfsk is RSID. You can see what happens when you use Fldigi. 73, Rein PA0R Big data signal on 3.588 , some form of data signal .. 200 /300 hz wide .. 2 / 3 second burst , but with a odd short narrow mfsk type of short pulse

From Kenwood's booth at the 2009 Tokyo Ham Fair, posted on YouTube in August, 2009. It shows a mock-up of Kenwood's next mid-range (US $2,000) 160-6 meter HF radio that targets most of the Elecraft K3's specs. A real one should be at Dayton 2010. One assumes it will be as easy at digital

[digitalradio] Need manual/schematic NX2P Radio Multiplier II (RM-2)

Hello and thanks for reading, I am in need of a manual and or schematic for a Radio Multiplier II (RM-2) from NX2P Electronics. It is an interface to connect four packet radio TNCs to a single transceiver. TNCs connected to the radio get a receive signal from the radio, but the radio will
