In reply to GW8OGI:
“snap decision”, “<100mW” and “10GHz” don’t live very comfortably together in a paragraph I’m afraid; especially from Wales. I have done several such activations on 10G but have only made contacts by making a nuisance of myself on the UK uW reflector and on KST, and having a mobile phone loaded with numbers of likely 10G QSO partners. Even lengthy “trails” of activations on the uW reflector only give a handful of contacts (and then only if you are lucky). The most useful person for you to get to know is likely to be Russ G4PBP. He has saved my bacon several times by being my only contact. He has a good site, a good system - and likes making contacts.
By far the best fun is to be had during the UK uW group cumulative contests where it is quite possible to make lots of contacts. There are five sessions each summer. If we manage to get a few more SOTA people active, co-ordinated S2S contacts would be a lot of fun - and even quite easy on many long paths. The other essential ingredient is talk-back. 2m is only monitored by uW people during known activity periods and KST is (very) hard work on a hilltop.
I suspect my comments above may explain why Richard 'ERP was not active this year. I think that Mike 'BLH has found it hard going as well. The uW people are not interested in chasing summits; and it appears that many are not really interested in having contacts!
All that being said, 10G is still a lot of fun and does represent an interesting challenge. I can only recall one time where I did an activation and made no contacts (Knott - N Lakes). With a bit of luck and a lot of effort some really amazing contacts are quite possible. But don’t expect them to come easy!
Looking forward to our first s2s. I can sometimes get out on 10G at short notice so feel free to e-mail me for contact details. Good luck!
