Re: My PA0FRI active loop receiving antenna
Boy I am with you !? To me github is unbelievably user hostile. Gedas, W8BYA EN70JT Light travels faster than sound..... This is why some people appear bright until you hear them speak.

Re: My PA0FRI active loop receiving antenna
Please. Could you post to something more "friendly" than github. Just a bunch of numbers and tables to me. Dave - W?LEV [email protected]> wrote: -- *Dave - W?LEV*

Thank you for pointing that out. That makes them marginally affordable, so I might get a couple of the one DIP version they offer. In the meantime, I came across the BFU520Y. It's not a monolithic

My PA0FRI active loop receiving antenna
Hi Folks, I recently built the PA0FRI active loop receiving antenna for HF (shortwave) use. The reception results have been highly impressive, especially considering the extremely constrained space

Re: Why not a resonant loop?
I live within long walking distance of the Homebush Bay, Sydney medium wave transmitter site. The signal strengths are high. With wideband antenna systems, the radio exhibits desensitization. A tuned

Re: Why not a resonant loop?
Great, but it's narrow banded! Again, my interests in loops range from below the submarine comms. (Schumann Resonance) through 160-meters. I have a tuned loop for 40, 30, and 20-meters, but here at

I am referring to any external balun or common mode choke (CMC). As you're aware, my application as a ham addresses both receiving and transmitting. For the longest time, a couple of years, I placed

Everett, I have one of your loop boards and have lost the instructions. I am going to resurrect my broken loop tht I pulle ddown a couple of years ago. I can't find an email address for you so would

Reply to Mikek: I use an 11 turn flat (pancake) wound loop to chase broadcast-band Dx in the US. ?The loop tunes from about 700 hHz to a little over 1600 kHz. A small silver mica cap can be switched

Re: Why not a resonant loop?
Bob, ?One of the major reasons to use a Broadband Loop vs a Tuned Loop, is that most people these day are using SDR? Receivers, with some being able to see up to 24MHz of bandwidth, at one time.

Hi Bob, I like messing with tuned loops as well. It was with Bertha (my first multi-turn tuned loop) that I was able to hear my first LWBC transmissions after several years of trying with numerous

Re: Why not a resonant loop?
With receive antennas, Signal To Noise is the important factor, and not absolute signal strength. However, it's very easy to be fooled into thinking that a weaker signal has a subjectively better
