Is there anyone who can help me get an Icom 781 working on FSK RTTY using the
W3YY FSK/CW board, MMTYand DxBase 2007? I,m wired as in the attached connection
diagram.
PROBLEM
1. Cant get rig to properly switch ON/OFF using the com 1 serial port.
Transceiver shows rtty signal power going out but it sounds like its in a fast
cw breakin mode rather than in a continuously ON transmit mode. When the
transmit switch on the rig is manually thrown, then in the output monitor it
sounds more like the rtty signal should sound.
Com Port #1 is being used to do this switching. What are the settings for the
com port?
Bits/sec -
Data bits -
Parity -
Stop bits -
Flow control -
Use FIFO Buffers - yes/no (Advanced Setting)
3. Is it necessary to make settings in the Icom 781? If so what are they?
Address
Baud Rate
Mark/space are set at factory defaults 2125 mark, 2295 space freq, shift 170
Any help would be very greatly appreciated.
