I Suggested a timed beacon system, a long time ago , similar to the
g3plx 5 meg monitoring system , where stations simply took an available
time slot and transmitted a long pulse ... monitoring software then
simply looked in the slots and gave a real time s/n reading , also
enabled stations could be in rx mode during there 'off' period ....
Then wspr appeared .......game over ..or is it ...
So what about a timed beacon system that uses allocated time slots and
the monitoring system keeps track or who is using which slot ..
what a strange idea .. but for LF may have big advantages
All on the same frequency -so no problem with Ae Q / B/W leaving the
band open for other modes
NO need for silly long tx periods , melting station accessories
ONLY needs rudimental time lock
OH and one little oversight .. all you need is a -CW- transmitter ,
no frequency shift keying , no audio to rf translation ,
Down side . needs some one to write the control software ........in fact
Andy , ran the basic idea on 500 for quite a while , using -one- of
the three time slots of the g3plx system, with Gary providing a off-air
on line monitor 200 miles north

Hi Rik,
The idea is fine. But, the problems I have with this are (1) Stations
don't always notify us who they are and what they are up to (Mike, G3XDV,
is a perfect example of how it should be done, keeping us FULLY informed),
and (2) is where I agree with Stefan, what about listeners (lookers) who
are not on this refelector? Two letters are of little use to them. I know
two stations near me who look on 137 but are not on here - for various
reasons.
You just can't beat a full callsign, even if you do sometimes only get
snatches of it. As it is, stations are often 'identified' by frequency
with very dubious visual evidence!

Hello Mike, all,
for propagation test purposes (sound much better than beaconing) all we
need is an unambiguous identification. A single character will lead to
confusion, but 2 characters should do the job.
So what about using the 2 last characters of the callsign ?
That would make most ID's more or less of the same length.
G3XDV would use "DV", OR7T would use "7T", DF6NM would use "NM" and so on.
I cannot see any conflicts right now (= 2 stations active in propagation
tests with identical 2 last characters).
Is national law requires a full id it can always be send in 12WMP CW.

OK, it seems that most people want full suffixes to be sent. I
believe I had good reasons to use a short ID, but I am happy to go
along with the majority view.
Of course the final straw was Mal threatening not to talk to me!
Beacon tonight (in addition to, and not instead of, real QSOs) will
be on 136.177kHz, 'XDV' synchronised with the start of each hour.
