10Ghz in EI today... update!


Tony Gallagher <tony_g_ireland@...>
 

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, which was pretty nice!
I headed to IO52MT on Woodcock Hill Limerick, unfortunately no qso was possible here, distance was about 130Km and we were both over 600-700ft ASL. I was a little disapointed!
What was interesting was we both heard each on very quick burst on FM, about S6, The bursts were about 5 seconds and had alot of very very fast fluttering.
I wonder was this tropo or some sort of scatter?

For setting the dishes bearing, I used Martyns method of standing infront of the dish. This worked perfectly!!! Thanks for that.

I think my next purchase is a cw beacon keyer for setting up. Can anyone recommend something cheap? I'm getting hoarse calling and calling!!

Regards

Tony

130km is a bit ambitious for a first contact, and the propagation you describe sounds very like aircraft scatter.

If it had been rain scatter, that would sound more like an Aurora signal.

The classic way to describe aircraft scatter is that you hear a 'chuff, chuff' type of noise. Often described as being like an old steam train moving away from a station.

The one I went for was the one designed by G4FRS and G4DDK see http://hamradio.lakki.iki.fi/new/Software/PIC/Beacon%20keyer/

The great thing about this design is that it's not expensive and you can decide what you want to have programmed into the message.

If you have the programming board (which I decided to buy as well for other PIC projects) then you can program up any number of chips with various messages on them.

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. But no steam trains.

Can anyone confirm if the steam train effect happens on 10GHz?
