I have the DX engineering loop (formally Pixel), which is an active loop similar to yours. I have mine located about 50 feet from my TX antennas. I run anywhere from 100w to 1kw. The DX loop has a PTT

Generally speaking the loops are unlikely to be damaged. However you raise a good point about any receivers that may be connected to them whilst you are transmitting. Most receivers will withstand up

Hiya Hope this is suitable for this group. I've been using a couple of Wellbrook 1530 active receiving loops for the past 20+ years for shortwave listening with FRG100 and AR3030 receivers. Finally

If one is designing a loop amplifier from scratch or modifying a design, then test equipment (big name brand, low end, or homebrew) is desirable, but if duplicating a well known and highly regarded

Hi Bob, the diagram on that page only shows a SDR and Transceiver sharing a single antenna. It doesn't seem to separate 2 antennas one for tx and one for rx.

Yes, I have a fellow ham who is making a 4-meter diameter transmitting loop for 160. He has yet to make a contact. He is building it to be taken apart for mountain topping. I've warned him about the

Hi is there a tx/rx switch for the?lz1aq amp so I can use my EFHW for tx and the?lz1aq loop antenna for rx on a HF radio that doesn't support a separate rx input. Kind regards Steve VK4SJB

Hi Dave Ok 1m dia.. in which case I would not even bother to try it on 160.. bandwidth will be soooo small it will be nigh on impossible to tune.( let alone the efficiency) .I suspect 80 is equally as

Hi Chris You may never find it, or if you do cure it..solar cells on roof? possibly, no chance there of course of asking neighbours to remove it.. My i suggest buying/ building a noise cancellation

The primary use of my transmit loop is on 40 meters. Once in a great while, it gets tuned for 80-meters. 160-meters is only an academic exercise. I use it during lightning season to get on the air on

Thanks, Mike. I'm with you. Dave - W?LEV

So to sum up: building a DIY loop is really cheap, once you've already shed 1000 commercial loop-equivalents in cash to gather all the necessary equipment and build an electronics shop in advance My

Hello Sean, Tuesday, January 11, 2022 Thanks sean and everyone who has replied so far. I am sceptical as to it being a washing machine as it has been present for eight hours today, with no more than

Hi Dave Why not nust make the loop bigger then use the 1200pf vc?

Hello all, This paper, with help of radioamateurs might be of interest:

Unfortunately a lot of machines and appliances these days are changing over from using traditional AC induction motors (which were relatively RF quiet) to variable speed DC motors, which require an

Hi Chris, That is a washing machine making that pattern – it’s exactly the same as ours, which is an Indesit so it’s probably the same across the other makes that employ the same motor system. I
