I just did it at about 2225z over the east coast of the USA. There will be many more passes tonight! Uplink is 145.99 and downlink is 145.80. Here is how to operate via ISS! 1) Do not attempt a connection to any other station. It is a fruitless exercise and only adds QRM to a very busy channel. 2) ANY TNC: Set UNPROTO to CQ VIA NOCALL. Then go to converse, and TYPE greetings or messages to others that you see on the downlink... If you see your packet digipeated via NOCALL, so did everyone else... 3) Kwd D700 or D7(G): Set one of your program memories for this application. Set data TX on band B to 145.990. Set data RX on band A to 145.800. Set packet to 1200 baud. Set path to NOCALL. Go to MSG GROUPS and add the wildcard "*" to the list so you can see messages to anyone. Operate normally. (D7A users see below).. 4) APRS: Turn off ALTNET filters. (In APRSdos set CONTROLS-FILTERS-OTHER) Set unproto path to NOCALL. Set radio to transmit on 145.99 and receive on 145.80. You can send messages to anyone you see. SHARING THE BAND. If you see your OWN packet digipeated (MY PACKET) then everyone else in the country also saw you, so no need to repeat that packet for at least 2 or 3 minutes.
