BEACON ON 136.150 KHZ
I have put on air an LF beacon, running H24, on 136.150 khz. This is of a
temporary nature and the frequency can be shifted to accomodate those who
have a problem with their xtal freq transmitters or who have local
reception problems.
I would very much welcome reception reports on these transmissions, my
callsign, EI0CF, is repeated continuously.
Checking with other LF operators, my transmit power has been increased
from low power to medium power on this test. Antenna current is 2 amps.
The rig is my normal Mosfet one, running with a much lower voltage. There
are a pair of IRFP450 in the final.
Loading coil inductance is 1200 uH.
NOTE. This transmitter uses a vfo, so there will be a certain amount of
drift, but I have set it up with a freq counter and I will try to keep the
transmitter running on this declared frequency. Initial drift took it up to
136.156 khz but it seems to remain quite close to 136.150 khz.
Once again, I will be delighted to hear from those who can hear this
transmission and under what circumstances they are receiving it.
Best regards

Hi Finbar,
I will try to copy your baecon tonogh or tomorrow morning and let you know
the results. Maybe it would be interesting to add 2 long dashes (10
seconds, separated about 3 seconds) every 2 or 3 minutes. This would make
the detection of you signal using DSP (Spectogram) much easier for those
outside the audible range of your signal.
As I'm writing to the LF-group I add a short weekend report:
heard (seen) in slow-CW : G3XDV (539), DF3LP (529)
heard in normal CW : G4GVC (549), G3KEV (579), GM3YXM/P (539), PA0SE (589),
DL3FDO (549), G3BDQ (539), OZ1KMR (559), OZ5N (529), G3AQC (529, DF8ZR (429)
73, Rik
