On Nov. 20, 1990 at 00:30 UTC Amateur Radio Stations WA3TLD and NS3U connected their stations over packet radio (TCPIP) protocol. The frequency used was 146.46 MHz. The rf output power of both stations was 20 watts. The total distance covered by the packet connection was 26 miles. The TNC's used were pk232mbx all mode terminal node controllers. The terminals used for communicating to the TNC's were HP48SX (on both sides of the link). QRZ HP (Are there any hams at the calculator division???) Paul WA3TLD

Paul WA3TLD ---------- What you're doing is exactly why I purchased my 48sx. I want to use the 48 as a terminal while making the first packet qso's from the top of Long's Peak. I had a RS Model 100 but that's far too heavy to pack 8 miles with 5000' elevation gain. So what terminal emulator did you use? Are you running with one of the standard cables or have you built your own? Have you ported the Ka9Q tcp/ip package to the 48sx yet? :-) Way to go!! Bill - WA7NWP Thanks

I just wanted to mention that Jim DeArras (WA4ONG) demonstrated two HP48's sending program objects and data to each other across Ace Metal Crafts' shop via packet radio back on the evening of June 2nd, 1990, following the formal Chicago CHIP group's HP Handheld User's Conference. (It's all on videotape, along with his informative talk on the new RS-232D standard.) Jake Schwartz
