Subject: LF: Lighthouse MF activity from OH next weekend
Hello,
I'm hereby announcing that OH1AH (The Top Radio Club) will bring 630m
equipment for the yearly lighthouse activity at Utö in the Finnish
archipelago.
We hope to make some daytime groundwave QSO:s over the Baltic Sea as
well since the Darlowo NDB in Poland was a good mid-day signal last
year.
Last summer we made some rough plans for how to put up a fairly decent
TX antenna and located a few old radials from a decommissioned
maritime NDB plus some thick general grounding wires heading for the
sea. There is almost no soil at the site so "artifical" ground is
brought up from the seashore at about 100m distance.
The International Lighthouse Lightship Weekend activity is 17-18
August 2013 - Duration 48 hours from 0001 UTC 17.8.2013. We will start
building the station on Friday morning, August the 16th and may be
testing in the same evening if all goes well. Due to travelling
arrangements we will have to take down all equipment on Sunday morning
as usual.
I have made a compact "expedition tuner" with a 600uH variometer,
universal impedance matching transformer and an antenna current meter.
The TX will be a JUMA TX500, 60W max. The setup was tested tonight at
my QTH and good signals were received at 350km distance so now it is
up to what kind of antenna we can produce on-site.
Utö is in the locator KO09QS
Due to the traditional activity on the HF bands this will not be a
pure MF operation. We will try to announce MF activity on dxsummit.
Unless local QRM or other factors favour another QRG we will try to
stay around 472,5kHz.
Comments and suggestions are welcome.
BR and hope to make at least a few QSO's
Paul-Henrik, OH1LSQ
