There are still a few HF Gates that are not connected to directly to a
computer and APRS-IS. One is VK3MY-4, which uses a KAM XL TNC to Gate HF
posits to VHF. The posits are digipeated by VK3RMD-1 and by the IGate
VK3SB-1.

>From memory a 40mtr APRS network sprang up for a while with Gates in VK7,
VK2, VK4 and VK5. But I don't think 40mtr worked as well as people would
have liked. Mostly due to the higher noise floor. If you look back through
this lists history you may be able to get some hints on what happened
depending on who long the messages are archived for.

There is also some information on ZL HF APRS at
http://zlhams.wikidot.com/aprsinfrastructure:infrastructure#toc7

Here is one discussion that happened 3 years ago on this list in regards to
20mtr APRS.

hi,
may I suggest to cling to the international APRS- Frequency 14,103 LSB
(1600/1800Hz), which is also used by many ships around the world (INTERMAR)
