Basic Introduction to APRS


 

¿ªÔÆÌåÓý

For some perverse reason, my replies to N2PEZ's question on this topic are not going through the groups.io remailer properly.? His original post gets forwarded but not my reply. ?

His original post was:

I am relatively new at using APRS (mostly Aprsdroid for public service tracking) but have experience using VARA on HF for Winlink and the DTN.
?
Is there a basic introduction to APRS with VARA on HF that I could read to get started?

---- My response was/is:-----

I have just updated and re-organized? the gateway page on my web site devoted to APRS topics.??? This may serve as a partial introduction to APRS, including APRS-over-VARA.????

There had previously been numerous references to APRS using MFSK and APRS-over-FLdigi on these pages.? These were topics related to earlier experiments with non-packet transmission modes for HF APRS.???

I have removed all the references (I think!) to APRS-over-MFSK, and have replaced them with links to APRS-over-VARA (a vastly superior data mode for HF) instead.? The revised web page on my site is:

Just that the title of the webpage still refers to FLDIGI, although most of the page refers to VARA. Just wondering if this an oversight, or intentional. Looking at it more closely though, I see that there are still references to FLDIGI on the page.
