RECENTLY I HAVE NOTICED A GROWING INTEREST IN PACKET RADIO ON USENET. IN ORDER TO SHOW WHAT IS HAPPENING IN THE WASHINGTON D.C. AREA I HAVE CAPTURED A SAMPLE SESSION ON THE AMRAD BRIDGE OR HF/VHF GATEWAY SYSTEM. THE SYSTEM WAS DEVELOPED BY BOB BRUNIGA, WB4APR/W3 AND IS ACCESSED VIA THE TWO LOCAL DIGIPEATERS (WB4JFI5 - AMRAD AND W3VD - AMSAT/JOHNS HOPKINS APPLIED PHYSICS LAB). THE BRIDGE HAS PROVEN VERY EFFECTIVE AT ALLOWING 2 MTR STATIONS TO COMMUNICATE WITH DISTANT STATIONS ON 10 MTRS. HOPEFULLY THIS DATA WILL BE SELF-EXPLANATORY. I WOULD BE HAPPY TO ANSWER QUESTIONS, BUT IT WOULD PROBABLY BE BETTER TO ADDRESS THEM TO EITHER AMRAD OR AMSAT. PLEASE BE ADVISED, I CAN NOT RESPOND TO QUESTIONS COMING FROM THE ARPANET.
