Thanks for your interest in my LF
preparations. You are probably thinking about Martin
GW3UCJ who was asking recently about getting a Velleman audio amplifier running
on LF.
I was lucky earlier this year to obtain a
Decca 5501 (Many thanks Mal). It is now tuned to 136 kHz thanks to the very
helpful and detailed notes posted on the internet by Jim M0BMU, Dave G0MRF and
Mike G3XDV. The antenna is an inverted L with one end in a tree 22 m high about
90 metres from my shack with a 13 m mast. Will try to get a neighbours
agreement for a 300m loop. For loading, two large clear-plastic
“mixing” buckets giving 800 mm height and 300 mm width. I should be
able to get 200 turns using a combination of Litz wire (thanks Mal) and
Flexweave. Not sure if it will give enough loading or what the variable tuning
arrangement will be.
A lot of work to do before LF Txing, so it
was good to have the 7 MHz X-Band QSOs this weekend with Mal on 136 and 500 kHz
to give me a try at LF ops. If any other LF op can do X-Band I would like to
test and there are probably other LF listeners who might like to try an X-Band
test. If you can do X-Band to 40m or other HF band I’m sure you would create
a lot of interest as your beacon is probably one of the first amateur signals
new LFers hear.
Unfortunately no amateur operation for me
today (Sunday) as my XYL wanted our grass cut between the Welsh rain storms
(also missed the openings on 4 and 6).

Where does the audio amp business come from. DK7FC
is always on BEACON mode, no chance of a QSO there. QSO only via Telephone or
email.
He cannot hear me although my signal is
audible/visible in the USA
to the west and Russia
to the East.

Terry,
What kind ogf antenna will you use and what is the L of your coil? Will you
start using QRO or will you use the audio amp in the first attempt? The latest
LF activities are very encouraging and i think we could go to a positive circle
to increase activity on that band. Furthermore you may be in a very good
position to try to leave a signal in Venezuela.
The last days there was no chance for me to leave a trace there but now Martin/YV7MAE told me he has time and bought some parts
for a loop antenna, so we will go on there very soon!
When will you come on air?
73, Stefan/DK7FC

I am still winding antenna loading coils for 136 kHz. My CW
is very rusty!!
I see you QSX 7033
for 502 – do you do the same for 136??

Join in. I can work at any speed that suits you. So
nice to QSO in CW where information can be exchanged in a few minutes.
Around EU CW has always been a suitable mode for
communications on LF. There is no need for long winded QRS when the signals are
fairly strong and both ends have suitable antennas.
