Re: LoG antenna trick
Thanks for the .nec file! That gave me an opportunity to finally install 4NEC2 and be utterly confused by it! :) I changed the geometry to reflect my plain 20m circumference loop and I was particularly curious on A) the influence of ground conductivity / dielectric constant on gain and B) elevation ...

Re: LoG antenna trick
That's exactly what I bought this switch for.

Re: LoG antenna trick
Testing YT embedding BBCode here (having a rough start on this, 'youtu.be' URLs will not work)... :) Here's a video I shot last year using the passive 20m LoG antenna before I shot the pics above: https://www.youtube.com/watch?v=EytGtqm3lXE That's 16,000km away from my secret LOG testing ground, on ...

Re: What's your favorite utility to chase?
Pretty much all of utility is a nice change from the usual to me, I like hunting NDBs or DGPS beacons in winter, DXing NAVTEX stations and of course VOLMETS and the NAT track frequencies, particularly when this gal is on duty: https://www.dropbox.com/s/vs74o2bb4d7wftr/Nice_gal_NY_LBR.mp3?dl=1 :) Edi...

Re: Matching an external antenna to the Belka-DX?
^^ What he said. :) I've used the Belka with very good results with various random wires, active and passive large loops and active whips... The only exception with the Belka is when the antenna is very lossy (has very little output) like an NCPL (e.g. the YouLoop), then the mismatch leads to rather...

Re: Unusual interference in Russian language on 7055khz
Welcome to the board! The 40m CW segment has been haunted by clandestine stations for a long time now, also jamming and OTH radars, so it's not unusual to hear broadcast-like transmissions there.

Re: The cardioid loop
Thanks! Yes, the more the merrier, the sense/loop arrangement came into my mind first because that's what I have in my trunk all the time (vertical fiberglass pole and some loops) but I'm also curious on (small) arrays in general, particularly a LoG array. So much to play with, so little time!

Re: The cardioid loop
Thanks for that! This is absolutely something I want to play with, it's easy enough. Couldn't you have posted that before I bought this expensive phasing unit to make experiments with the original ADF antenna principle (loop + sense antenna) at the dike?

Re: Malachit SDR (CHN clone) + Sony AN-LP1 ampl. loop
Like that?
(That's a YouLoop with a LANA-HF, temporarily mounted on a boom outside for a test. That's all plastic cable duct profiles off the local DIY store, very easy to cut and held together with small screws and zip ties)
