Greetings All.

IF and it is an IF the RS-232 is fully implemented, at least + and - 12V on transmit and a full receiver, ie 1488/1489 pair, then it is very surprising how far one can go with RS-232.

I have done it inside factories at over 800 ft regularly and I run an RS-232 line into a RG-59 Coax here on my Island qth and it goes for over 1200 ft with excellent results at 4800 bps.

It is good to see everyone who tries running a Pegasus or any form or radio over a LAN (or the Internet) is hurt by the latency and absolute delay issues, this is NOT an issue if one uses standard PC MODEM's and runs over the telephone switched network.

Good Luck to everyone doing things new ways....
