[aprssig] FWD: Re: HF APRS igates

[Joe Bennett]

I think there is confusion between the APRS format and the JS8CALL format. If the APRS format was used to send in JS8/FT8 it'll take 30 minutes to send the packet. I'm being facetious but it will take a LONG time... The JS8CALL format is converted somewhere else in the network to the APRS format and then dumped on the APRSIS. I'm guessing after its forwarded to JS8NET?

> It might be better to use a correctly formatted APRS message, so that other APRS clients would be able to interpret your packets once they are I-gated. Packets starting with @ are position reports with timestamps, and have a specific format of timestamp, latitude, longitude, and APRS symbol code. If you want to identify your position by Maidenhead grid square, either the Status packet format (started with > ) or the obsolete Maidenhead position format (started with [ ) can be used as well.
