Re: Kite lifted antennas
If the UnUn is DC shorted, like this one http://www.jumaradio.com/The-challenging-Unun-Transformer/ and if the ground goes to a decent ground stake, there shouldn't be need for a bleeder since the antenna would effectively be connected to ground at DC; alternatively one may try a galvanic transforme...

Re: Best beginner CW transceiver kit to start with
4StateQRP is a great source alright. I've built a few of their kits with good results. Check out the transceiver kits at "qrpme.com" they also have ALOT of other useful and quirky fun kits to learn building with. Be prepared to spend some time at the site just looking around. 72 W5GUS Dal...

Re: Counterpoise with TX500
if using an EFHW then you won't need a counterpoise (ok, a short one may improve radiation but it isn't mandatory), on the other hand, if using an EFRW (a so called "random") then you will need a cointerpoise to both improve radiation and matching through the necessary (in this case) ATU I...

The perfect POTA/SOTA rig
ok, perfection isn't of this world, but let's just try to play with some imagination, start with an existing or a non existing rig, and add all the features you feel important for a POTA/SOTA activator or for a hunter, come on, let's raise some holidays dust :) P.S. keep real, don't ask for dilythiu...

Re: Portable 10M Yagi ?
Andrew, How would you go about constructing the jungle job? For 28MHz, you'd need about a 16 foot reflector. Do you make it out of aluminum pipe or PVC with wire inside (or outside)? To me, it sounds a lot more difficult than a Moxon with a 3D printed hub - maybe because I've already printed the hu...

Re: Portable 10M Yagi ?
A moxon may be a nice antenna, but... please see my observations; and then, a "Jungle Job" is really easier to build and deploy in almost half the time needed to deploy a moxon and is much simpler than the mox if you think at it for a second, plus ... well want we talk about performance of...
