Hi David, Glen and Jeroen, 10m, the RF side concerns me, the ionosphere is just not co-operating.
The MUF is not lifting up there so the coverage area isn't that good. Hence my concentrating on 20m as a max frequency. Using 20m a whole country can be covered. And it happens often enough, even daily for hours. Thanks Jeroen for the networking thoughts, as Full Duplex from one site on HF is realistically not possible. (I've looked at cavity designs for 100KHz split on 29MHz and you need about four cubic metres!!) As mentioned, I've picked up the Codan 8528 for a Codec2 repeater.
