    Re: KX3/PX3 Stands

    I find that when using the PX3 portable I often need to set it's angle to minimise reflections from the screen. Invariably the built in legs will not support it at an appropriate angle (which is...

    30m 2 element wire beam.

    Yesterday I put up a couple of 30m inverted Vee antennas. One was driven, and the other was a passive reflector positioned ~1/4 wave behind and about 3% longer.

    It was set up to beam...

    The more I think about this the more complex it becomes ! On reflection I think it should be left to common sense. Claimants can ask for decisions as and when they arise. That way "case law" can...

    I think there are several aspects to consider. I'll give it some thought.

    I think 6 digit squares are a bit big for this as they are over 2.5 miles a side! I have some spots I use that are with the same 6 digit square. Does this mean that you can only use each 6 digit...

    Re: Portable antenna for 40, 60 and 80 m

    I see. I have a wire up the centre of mine so it goes the full length. An SGC ATU at the bottom will tune it on all HF bands above 40m. I think it will tune on 80m as well, but I don't think I've...

    Re: Portable antenna for 40, 60 and 80 m

    Did you mean 40m 1/4 wave ? Mine is resonant on 40m and with the addition of 8 x 10m radials it is a near perfect 50Ω match as well.

    Re: Portable antenna for 40, 60 and 80 m

    Use thicker wire then ! ;-) That will get the ratio back the "right way round" :-) Radiation efficiency is far more to do with the earth system than the pole height. That's why I wrote "with lots...

    Re: Portable antenna for 40, 60 and 80 m

    A trapped inverted L with lots of radials might be a solution. 10m Up and 10m Out for 80m, 60m trap half way along top section, 40m trap at junction of vertical and horizontal sections (at top of...

    Yes, but don't forget that you can return to a site multiple times as long as there is two weeks between activations and you visit other sites between reuses.

    I don't think so. The only case where an activation can be used for more than one thing is given below.

    Re: Out /P for club top band net

    I'm working on a MkII with what I hope will be an improved loading coil. A bit more "fiddly" to build but might provide a better coil. I'll write it up when I've built it.

    Out /P for club top band net

    My local club is trying having a top band net, Tuesdays at 19:30 (BST) on 1925kHz.
    I put up a 10m center loaded vertical with 5x20m radials. I was one of the strong signals on the net :-)
