Rudak To Carry Packet Radio
RUDAK-2, the second generation packet-radio experiment to RUDAK, now is completed, tested, and fully integrated into a Soviet geological research satellite, known as GEOS. It will fly in July and carry not only a Mode B linear transponder for SSB and CW contacts, but also a variety of packet-radio experiments. The digital communications capability of RUDAK-2 is astounding five different data rates from 400 bit s to 9600 bit s using various modulation schemes. Radio amateurs will have the choice...
Hf Packet Radio With Psk Successful
Earlier this year, Walt Kaelin, KB6BT, and Julius Breit, W9UWE, got several multimode TNCs that have phase-shift keying PSK modulation.

Both stations are using TASCO TNC-24 MKII TNCs and Kenwood TS-440S transceivers with power outputs of 50 watts into vertical antennas. They are 4000 km apart. Much of the...
