Again, Demtre was talking about IP/PACTOR, not IP/HF. IP/HF has been done for
years by hams using conventional packet radio protocols, and I'm sure there are
any numbers of ways of achieving it satisfactorily.
The card in your brother's PC is extremely unlikely to be operating on HF, let
alone 25 MHz. Far more likely to be a point-to-point terrestrial VHF or UHF
spread spectrum system.
