Re: Suddenly getting "Unsupported Packet Format" looking at raw packets with TT4


 

¿ªÔÆÌåÓý

"Unsupported packet format" is just aprs.fi reporting that it's parser doesn't understand that specific packet.?? It doesn't affect (AFAIK) other packets from the same station.

Why are you using a non-standard "to-call" or destination callsign??? You're actually specifying that you want to run in the "K2CZH" alternate network.?? From aprs101.pdf (a document you should read and study if you're going to be reading raw packet formats):

Any other destination address not included in the specific generic list or the other categories mentioned above may be used in Alternate Nets (ALTNETs) by groups of individuals for special purposes. Thus they can use the APRS infrastructure for a variety of experiments without cluttering up the maps and lists of other APRS stations. Only stations using the same ALTNET address should see their data.

Thanks!? Somehow I missed that.? I'm still getting occasional errors but nowhere as many.? I wonder if all the unsupported packets was why I wasn't appearing on aprs.fi maps (even with a 50' high antenna at 25w and watching the HT recieve the outgoing packets).? Now its getting through alot more often.

Thanks,
