Re: 122?
I had been holding out for David Minchin's 122GHz thing, but I am not sure what's become of that. It looked excellent in Dubus and I think would be my preferred solution for 122GHz, I think it is

Re: Commercially made Yagi for 2.3 & 3.4GHz
I had a special three section boom made for my 112 element 'Blowtorch' QLP to enable shipping. I also provided my own trombone support.
When I tried to bring the original back through Dallas Fort

They may do a decent discount on 9cm loop yagis now the US have lost the band, but heaven only knows what the shipping would

Re: Commercially made Yagi for 2.3 & 3.4GHz
For 3.4GHz you may do better with a flat plate antenna.
30cm square, gain ~ 21dBi
Not sure if you can get them for 2.3GHz

Commercially made Yagi for 2.3 & 3.4GHz
Folks, I have now got transverters running for 13cm and 9cm. I have successfully used them with small PCB yagi's. My ultimate goal is to make a feed to a NOS 1.2m Andrew dish sitting in my shed,

Re: 2320 PA Modifications?
I was right to think I had more power than I measured. Dumbkoff here just looked at his lead to power meter which still had attenuator attached. I thought I'd used a 20db with my good 30db

Re: 10Ghz last night
My 50cm dish was up at 60ft above ground,, 13cm Yagi at 75ft. QTH is 700ft asl. Clear in nearly all directions.
IC-9700, Kuhne transverter, DL2AM PA, 5w, Procomm dish/feed, GPS locked, Positional

There was mention of some zoom or such on using 122Ghz soon.
Where and when?

Re: 10Ghz last night
Hi David, NBFM works well when there is a very high level of doppler spreading from rainscatter, which can make SSB almost incomprehensible. Obviously you need a fair bit of signal to get it to work

Re: 10Ghz last night
I also extend my thanks to all who tried last night in what was my first 10 Ghz nb experience. I was QRP with just 100mW at the waveguide probe. G4ZTR was a massive signal with me but he did not

Re: 10Ghz last night
Well 0.1 deg precision and resolution. I doubt if it's accurate to that but it does seem good to the 1 deg that I wanted - at least it gives a consistent reading for the level of my

Re: 10Ghz last night
If it works it works Jerry sounds like a good fast easy fix. When I did 6m /p every month last year I used several rolls of gaffer tape over the season to solve problems you would not dare do at home

Re: 10Ghz last night
Hello,
When i go /p with my µwave equipment, i use a yaesu 550 EL rotor. Because the controller box isn't accurate enough, i got myself an electonic water (spirit) level. Taken out the display-sensor
