I just finished the 'upgrade' of my VFO to frequency shift keying. Tonight
(29 november) I will try to do some test transmissions in DFCW (Dual
Frequency CW) between 20 and 21 UT on 137700Hz. Dotlength will be 3
seconds, shift will be 8Hz (highest frequency is 'dash', lowest frequency
is 'dot').
For those who want to look : 'dry-test' have shown that the 'screen-speed'
of GRAM should be set to the double value as you would use for 3 sec. / dot
If dots are too short on the screen it is a bit more difficult to separate
a series of 'dots' or 'dashes'.
Test will be done at low power (250W RF / 70mW ERP).
