I was scanning around and found similar signals popping up primarily between 27.500 and 28.000 Mhz. There were several of these with random signal strengths. Any idea what they may be?

i’m new. what’s this?

Do any of the world's national shortwave stations ever broadcast CW?

I prefer the minimalness of a CW-only receiver, but I want to listen to international HF broadcast, for the variety.

I want to do shortwave DXing so should I put a lower random wire antenna from my room to a tree or should I put a loop antenna on top of my chimney for shortwave listening

Hello

I am trying to copy RTTY on various frequencies using my IC 7300 and inverted V antenna. The standard amateur radio settings don't work. What is the Mark freq and shift width I should be using? I tried all different settings but all I get is gibberish.

Hello all, this is a bit off topic, I apologize. I’m looking to buy a portable “international” receiver that doesn’t require ham license. I’m currently located in USA but want to listen to radio stations from my home country: Ukraine.

Original design is from Harry Lythall, SM0VPO

I like the design, size, and my build ability for this antenna. How would it work for SWL outside of the 40M band? Would I want to connect my DX-390 to the feed loop or to the capacitor skipping the feed loop.

I would like to eventually use this for the 40M band but first need to upgrade my license.

Is there other square spiral loop antennas out there similar to this for SWL. I don’t really want to get into winding baluns but buying a balun and/ or capacitor at a reasonable price is fine.
