Audio recordings SM7LCB in JO86GH
Last updated 4 August 2010.
Welcome to listen
to my audio recording during NAC 2 m contest 3 August 2010!
During the spring 2010 I installed
a 2 m yagi antenna which is Vårgårda 6 el yagi. But just 6 hour before
the NAC 144 MHz contest in August 2010 I connected this antenna to my
remote station. I have a 2 m output on one of my switch boxes before
the transverter line for the microwave bands. This output comes from an
ICOM IC-706MKIIG set for about 20W output at the station. After that
follows about 50 meter for coax to the switch box and then extra 14
meter up to the antenna. At the switch box output I have about 4W so
it's less then 4W at the antenna feed point. We say 2W so total loss
from station to antenna of 10 dB (20->2W). This gives a bad noise
factor of the receiver also with 10 dB of attenuation before the poor
receiver. I will during the winter try to build a needed preamp and
also a solid state power amplifier.
When I first switch in the
antenna I wounder i anything was connected at all. But I found the
beacon OZ4UHF and also SK4MPI so I think the antenna was connected and
some strong signals were possible to receive without the preamp. When
the contest started I also find signals from station calling CQ on SSB.
But the 2W or so output didn't give any QSO's. Switched to CW and then
some QSO start filling the logbook for the first time with remote 2
meter operation from SM7LCB in JO86GH. I have worked some QSO before
but that with local station (IC-290E) connected to my vertical antenna.
QSO was nice during this evening but best was OH1F KP01 (640 km). After
that it was really nice to listen on the aurora signals after the
contest. It was long time ago I listen to this and now I'm happy to
hear it again. I think the aurora and ES is the driving force to start
operation on 2 meter again. And of cause the high activity. But for me
I logged less QSO on 2 m then I do on 23 cm. Maybe the poor output
power and lack of preamp have something to do with it.
