Dear Keith,
Many thanks for an enjoyable evening plus the meal and drink. I'm sure I
will return the favour at some point.
It was also good to see some new folk that I haven't seen or spoken to before
at the pub.
As for the radio, my Kenwood THF7E worked well. The second harmonic made things
so much easier when I was close by. However the transceiver would only go to
1.3GHz so I couldn't quite the third harmonic. I did knock a quick 10db
attenuator which I don't think was enough. Next time I will go higher and maybe
use the variable attenuator I was making. The new 3 element antenna (even with
oversize aluminium) worked well. My handle made the use a whole lot easier but
it does make the size bigger and not so discrete.
Maybe if the next fox hunt is on a free weekend then my second hunt maybe
better although I'm proud to have made out Keith's location after walking up
and down TW common 3 times from starting high up on Mount Ephraim.
73 de M0NAY
Regards from Chris Pegrum
