Hello to all, If you do Digisstv transmission you must use very small pictures, for example the Mini_Map.BMP file (in the Multipsk package) which dimensions are 80x70 pixels. To send this file, it will last: * 1 mn 15 sec in Packet 1200, * 3 mn 50 in Packet 300, * 6 mn in PSK220F.
It's not very rapid...this is due to the compression used. It's a Runlength algorithm which is applied line by line. The transform might be in two dimensions as in JPG to be more efficient, but this line transform permits to get the picture at any time (no block). PSE: in Packet, don't use "Immediate stop of the picture transmission". There is a bug on this button (fixed now). 73 Patrick ----- Original Message ----- From: Roger J.

What pixel sizes are recommended for MFSK images? Been so many years since I did it I no longer remember. de Roger W6VZV
