Where the incident is not
within VHF range the
radio link must be made
on High Frequency.
Any network station in the
world that can be reached
may be used.
There are more than 50 HF

How do Hams do that?
WL2K HF MODES NOW INCLUDE
PACTOR 1,2,3 – Firmware-based data modems.
Legacy multimode TNCS (KAM+, PK-232, etc.) support P1.
More expensive ($700+) SCS PTC units provide P1, P2
(up to 8X P1 speed), P3 (up to16X P1 speed.) and P4
(non-ham frequencies)
WINMOR – New soundcard-based protocol provides up
to 2.5X P1 (500Hz BW) and 10X P1 (1600 Hz BW).
