It's called PKTMON12. The program is avail- able from ftp.funet.fi, listed as PKTMON12.LZH. I'll convert it to a ZIP and upload it to DRIG BBS this weekend. This program works great and is FREE. The op-amp interface circuit is shown in the documentation of JVFAX6.0, HFFax, and HamCom30. Just connect the 741 input to the receiver speaker leads and start copying packet (1200 Baud.) The system also will decode HF packet although I haven't tried it yet. ============================================================================ The opinions expressed above are my own and do not reflect those of my employer or my wife.

Subject: Software to drive a radio data modem? To: ham-digital@ucsd.edu Hello friends, I've got a Satelline-1AS Radio Data Modem here on my desk. This is not a Hayes compatible thing. It does half-duplex communications. By switching DTR on on the RS232-port, the Radio Modem is powered on. (signalled via DSR). When CD is switched on, there is something to receive. To send something switch on RTS and wait for CTS. This can take a while because it's possible that the radio channel isn't free yet. This Radio Modem is from a Finnish company and is also known by the name MOBIDEM. Does anyone has a piece of software to test this thing out, before the application for this thing is written? Is there a FAQ for this group? My appologies if my question is inappropiate for this group. Greetings, Harrie. ------------------------------ End of Ham-Digital Digest V94 #293 ******************************
