Hello All
Grateful thanks to all who have posted reports on my 501.3
khz beacon.
The problem at this location on the South West coastal tip
of Wales
is massive noise pollution from the adsl broadband connection.
This takes the form similar to the “galloping horses”
effect that were previously experienced from Loran sidebands on 136. Receiving
on the Tx antenna is impossible.
Having constructed a shielded loop to a design developed by
Finbar GI4DPE, I find that although I can null out a certain degree the qrn it makes
weak signal reception still virtually impossible.
I have on a temporary basis, access to a noise free area
about 80m from the house. To date, I have only heard and worked the 2 GI’s
and my near neighbour GW3UEP who is about 50km NW of me. We exchange 599
signals. I have yet to hear any signals across “the border”
Hope to locate the loop in the quiet zone at times
indeterminate over this weekend, chores etc permitting. The obvious
problem with the loop is that if called by someone on whom I am not “beaming”
I don’t hear them!
Trust this explains my lack of response in the past.
Final comment—136khz was much easier!
