ALTERNATE MODES
Brief over view of experience and experiments with alternative modes of communication.

Using the well established soundcard interfacing technique I have developed a flexible interface between the computer and the TS430 HF transceiver and the FT736R VHF / UHF transceiver. This has allowed transmission and reception of SSTV (Slow Scan Television) on a variety of bands through HF to high VHF bands and RTTY (Radio-Teletype) and PSK31 on the 20 and 40 metre bands. The extremely narrow band nature of PSK31 has proven very successful on both 20 and 40 metre bands during the period of low solar activity with very large numbers of stations world wide taking up this mode over recent years.

I have also had limited success in at least monitoring meteor scatter stations using the WSJT software developed by Joe Taylor (KIJT). This is something that will need to be explored further in the future!

In mid 2007 I participated in a number of experimental contacts with Tony Langdon (VK3JED) using a new digital voice mode called FRMDV. Despite early difficulties we finally established a perfect high audio quality link, but that is the nature of real digital communication it either perfect or non-existent.
