Title: A 'dead band'. But...
Post by: GM0LVI on October 20, 2014, 21:43:00 UTC
There was a solar disturbance late today and most of the upper HF bands had collapsed but late eveningI decided to have a hunt around to see if anything was about on 20m and much to my surprise found PR7AA/QRP calling CQ with a 579-599 signal with hardly any other signals on the band. I worked him (with 5W) and then was called by LU5FF but sadly didn't manage to complete the contact.
I suspect that enhanced grey-line had an effect as the RBN image shows.
The moral is that just because a band seems dead it's always worth a try even with QRP!

Congrats! What kind of antenna were you using and at what height?

Hi Joop!
The antenna is a 5 band 2 element quad. In this photo it is at its full height - about 11m, but I very seldom have it elevated, in fact I've only wound it up twice in the past year and normally the centre of the quad is at about 7 metres.

Very nice Dave!

Been using dipole antennas so far... Guess I should start thinking about erecting a beam or quad. I am going to buy a mast with a winch, so I can take it down easily when it's windy. Maybe a spider-beam will do, it is very light so I don't have to use any guys.

A spider beam could be a good option Joop. Nice and light and doesn't need a heavy-duty, expensive rotator. Reviews on EHam are very good and quite a lot of expeditions are using spider beams.
