For a fixed installation - looks like a worthwhile project! For portable usage and small spaces, well -> SULA!

At times I regret not having gone down the DIY electronics rabbit hole and I still find the thought of making simple but powerful radios interesting. What curbs my enthusiasm though is the mechanical side, how to make not only something that works well and looks good, but something that has a proper...

Reddit, the self-proclaimed "homepage of the internet" is known to be a pretty toxic place. Since it has some "subs" related to all of my hobbies, e.g. r/shortwave, r/amateurradio and r/hamradio I occasionally read the newest posts there anyway, but more for the entertaining crin...

I figured this would fit best here, even though it could also fit in "Utility" or the "SULA" thread(s): Last Monday I took the chance to compare the Belka and its whip with the IC-705 and the SULA (and also the whip against the SULA on the Belka alone), with some results that cou...

Doubt a relay or airtime broker or pirate would fire up square on 10mhz. Certainly not intentionally! If not overload, a mixing product. Weird thigns happen when bombarded with strong signals or a peice of your gear failing. Well I'm pretty familiar with these failure modes. "Mixing" and ...

I'd say alaska, bar none! That could be true, due to low population density (low noise and plenty of space) and being on top of a ring of continents framing the Pacific ocean with e.g. interesting MW activity, so a lot of true DX targets with nothing in between. Your very high latitude (62°N) offer...

Hi Paul, Nice to see you here on our little board! Of course intermodulation is the first thing coming into mind when you hear something like this, that's why you can see me turning down the RF gain (which acts directly on the RF input stage on this radio) in the video. But besides intermodulation p...

Ah yeah I know that super fine brown Sahara dust, I have it on my car every early summer but that's not it. Apparently high electric charges under rain clouds long before they reach the thunderstorm charge levels are known, for example I found kite surfers reporting that they got shocks when they en...

I just had a scary thing happening at the dike: When I arrived there this evening, I could already see that the rain forecasted for 0:00 local was about to arrive an hour earlier. I parked and stuck the Belka + whip to the side window anyway. After a while I noticed that the AGC was triggered (gain ...

A few weeks ago I stumbled upon 12365kHz - I heard a coastal weather transmission in English at the dike, with a signal that made me believe it would be from the UK or the US. Back home it turned out it was - of course - VMC Charleville (Queensland, eastern Australia), the sister station of Wiluna R...
