Propagation blackout predicted 21/12/07

For the incredulous, an E layer supported propagation blackout will occur from 0600z onwards Friday Dec 21 2007. Why? Experience has shown that because those of us gainfully detained at respective QRL’s during daylight hours might have chance to be by radio by late afternoon Friday the propagation...

Re: Buddipole antenna's

For those interested in the OzziPole, I've now been using one on-and-off for a few months when portable. RX's very well considering and considering it's size the TX perfromance is acceptable. Is very quick to set up (under 10 minutes) once initial measurements have been completed. http://lh3.google....

Re: Remote / Automatic station for record purposes

Owen This was a subject that over the last two cycles received a reasonable amount of attention within the 6m DX fraternity... and spurned a magazine article about 'Intelligent beacons' by Chip Angle (and forgive me if I'm wrong - Steve OT do you remember) utilising CW for TX/RX. The concept was to ...

I suggest, and am biased, that regardless you need 'gain' to succeed. Be it at the cycle minima when you need everything to...

Re: Buddipole antenna's

You can now get an Aussie version - the Ozzipole. Its a kit being distributed by the Coffs Harbour club (I may be wrong here) and it was advertisied on VKHAM (<$100)

It sure aint a gain antenna, but might get you on air quickly in a remote situation.

Kevin, Latitude plays an incredible part in this, what you can achieve at the latitude of QG48 (21 degrees south) is vastly different to that which can be achieved at QG62 (27 degrees south), and then for VK2 and VK3 it's even more pronounced. We cant draw comparisons between such significant variat...
