What follows is a small trick which allows to maximize the performance of the LoG (Loop on Ground) antenna, I won't add details about the antenna since it has been discussed on SWLing, but if one doesn't know about it, the infos about such an antenna can be found on Matt Roberts' page, here http://w...

the someone is me, guilty as charged, your honor

seriously, wanted to test the function since as you wrote, it's an important one

what puzzles me is the fact that, if the switch was used in those "field containers" it doesn't (seem to) have some kind of support flange or the like

Great advice! Too bad there are only 2 types of hams, the guys who read stuff like this and the guys who complain about their PA doing strange things (and blame the PA for it) in partially unreadable transmissions because the in-shack RF is destroying their modulation. :mrgreen: I have a guy who's ...

Ok this one is more about tx than rx, still this old trick is easier and quicker than assembling an RF ammeter; in short, if one suspects about "RF in the shack" a quick way to check is to find the band where the problem(s) are more evident, at that point, pick a run of insulated wire and ...

A note. Thomas, what about some section dedicated to the SWLing post blog ? I mean, a section with automated posts and links to new blogposts, it will act both as a reminder and to allow people to further discuss the topics

And that antenna switch? That thing is INSANE! What a find indeed. I may re-post this as an article on the SWLing Post. I'd love to learn if there are other BNC switch alternatives out there. Cheers, Thomas Hi Thomas, sounds like both SWLing and QRPer got their forums, I just wonder if it would hav...
