Digimodes


Manuals
 

I have just started to use "DigiModes", and confess to being a complete novice. As such, I welcome any information, or comments about my activities in this area.

My main operations have been with "BPSK31" and "RTTY". However I have just started to receive"SSTV" images.

I use a home made (supplied by G0TSG) soundcard interface to operate these modes, with reasonable success.

This was a cheap interface, purchased from junksale. It is very primitive, with a manual TX switch for keying the radio (because my radio does not have VOX). The input and output levels from the unit are also poorly matched, and require the soundcard in my computer setting to almost Zero for both MIC input and speaker output. I was going to try a little more experimenting, but as I would prefer an interface with automatic switching, have left it while I go in search of a more sophisticated interface. The interface by G0TSG has served its purpose well, as it has enabled me to explore digimodes, and opened them up as an interest for me to explore further.

Software

I currently use two programs. My choice was dictated by the one important criteria, in that they needed to be free.

I use the excellent PSK31 Deluxe for PSK, and the comprehensive MultiPSK for everything else.

The user interface is very cluttered and not user friendly. I also find the way it shows text being transmitted a little awkward. (I prefer the PSK31 Deluxe way of showing all the text, and crossing off sent text, as you know where about you are up to in the transmission.

MultiPSK is not very intuitive here, and reading the instructions (yes occasionally I do do this!) hasn't helped. I think more research is required.
