APRS frequency world map

sbd sbd

Hi all

I want to update my world map of VHF frequencies. You might have seen the map sometimes modified but sometimes with my callsign G6UIM still there.

Anyway I want to check if frequencies are still the same and if there are any errors in it, I think there are as some of the info was really difficult to obtain, such as what the national radio society says and what is actually in use.


So the request is if you chat to someone on HF or via APRS please could you let me know, their APRS frequency


Will obviously release copyright free
