Hi Dimitris,
I have another idea:
[ -F ] Factor . Factor is a Multiplier for the output frequency and
DFCW shift. Factor = 1 if not set otherwise in the command line. You
know, some PAs use an /2 or /4 divider (e.g. CD4013) to generate a
opposite phase rectangular signal with a perfect 50% duty cycle.
I have modified the wspr.c file with a (fixed) factor 4 to 4xwspr.c.
This works very well...

There could/should be a number of options like
- [ -B ] beacon mode
- [ -E 0500 ] stop time is 05:00 UTC
- [ -S 0.2 ] 0.2 Hz DFCW-shift (if this parameter is not used in the
command line, i would choose a certain ratio of DFCW shift and dot
length. Then the DFCW shift is set automatically)
- [ -R 2.5] Dash/Dot ratio is 2.5 for QRSS (3 without setting this
parameter)
So, for example:
sudo ./[mode] [dot length] [frequency] [parameters] [message]
e.g.
sudo ./dfcw 90 136172.5 -B -E 0630 "dk7fc "
=> transmits a DFCW-90 beacon on 136.1725 kHz until 06:30 (system
time) with the message "dk7fc "
