Re: 10Ghz in EI today... update!
Dave
I have not heard anything sounding like that on 10GHz. I have heard occasional strong pings and fairly constant level signals drifting with Doppler - both of which I assume are due to aircraft.

10Ghz in EI today... update!
Hi everyone,
Worked EI3IX/EI7FAB/P today from Galway IO53PK or there abouts. They were in IO53LU
Distance was about 50-60Km. Signals 9+ were exchanged. Tried FM on 10Ghz for the first time today,

Re: beam and coax
Hello Chris - if you new to 23cm then *welcome* - it is one of the best microwave bands..
Keep the *rule of thumb* for any coax loss at 1dB or less - not sure of antenna prices in the UK but here in

Re: beam and coax

It all depends....
How much space do you have on your mast for the antenna? If it is limited then a single long yagi would be a good bet (eg the 67 ele Wimo/SHF or 55ele Tonna). If you have

Re: beam and coax
Ecoflex 15 is very easy to handle and the loss is very nearly as good as
LDF450. You will probably need a mast head pre-amp unless your coax run is
very short.

Re: 24GHz in GW
Hi Dave
Your nearest bcn on 24 GHz is probably GB3ZME inIO82RP. 1 watt PA, 10+10 slot. It got a bump during erection, so nominal freq.( 24048.910) has gone a bit AWOL - around 24,048.780 atpresent.
