Re: The Belka DSP/DX appreciation thread

Short of bothering Alex with that certainly annoying question I just asked my bank and it looks like they have suspended their service with Alfa too. :( Re the Belka DX Max - the markup is 80€ and of course there is some profit margin in that price but you also get some upgrades for the money, the m...

Re: The Belka DSP/DX appreciation thread

I really need to take mine out more; it's so much fun using a high-performance receiver in an electrically quiet spot. Believe me, I'm not a big fan of walks, particularly in fall, winter, spring and parts of the summer. :) But then again, this radio occasionally made this so rewarding that I walke...

Re: The Belka DSP/DX appreciation thread

Here's what gave me the urge to create this thread: I usually have the Belka (now the DX model) in the breast pocket when I do walks and when I'm listening to hams in SSB, I'm often shocked how much true DX (IOW stations from another continent) I can hear, often stations from the East Coast ragchewi...

Re: The Belka DSP/DX appreciation thread

given the state of the world where the Belka comes from, at this moment it is very unlikely that I can get my hands on one. Same here. Alex'' shop )https://www.belrig.by is still there, Belkas are in stock and I think the (US and EU) sanctions against Belarus are not affecting this kind of private ...

Re: The Belka DSP/DX appreciation thread

Well, let me start by writing that the belka deserves appreciation, then, this same thread may also be useful to post comparisons between the belka and other receivers and discussions related to external antennas which fit well or poorly with that little wonder :) Absolutely! :) Speaking of the rev...

The Belka (-DSP/-DX/-v3) appreciation thread

Introduction Maybe it's good for Alex (EU1ME, the maker of the Belka) that his radio is not all that easy to obtain and also not that easy to comprehend what it really is -- otherwise he'd probably be so swamped with orders that potential buyers end up on a wait list. :mrgreen: To the uninitated, t...

Re: 104's log thread

@104: The thread you posted on had the topic "what's your favorite (type of) utility to chase", so that's not the right place to post your logs. I have moved the OT discussion into your own thread and will merge your other logs into it now. Edit: Done, nice opportunity to try the split/mer...

Re: LoG antenna trick

Just a note, the LoG with a perimeter of (about) 18m will mantain its pattern up to about 10MHz, willing to go further up in frequency you'll need to reduce the loop size, the image below shows the patterns at 18MHz for two LoG antennas log18.png to the left you can see the pattern of the 18m LoG, ...

Re: LoG antenna trick

Ollie, a bit of warning here; NEC modeling may be addictive and you may start modeling an antenna and adding to the model wireframe models for buildings, trees and so on :lol: I couldn't stop playing with it all afternoon, good point! :) OTOH, I understand very little of it, likely not enough to us...

Re: Matching an external antenna to the Belka-DX?

I have used a Belka DX outdoors and recently compared the supplied telescopic with a 75 foot circumference loop on ground. My tests have not been rigorous or extensive but it was immediately apparent that there was a clear advantage to the LOG in SNR. It was enough that on a weak signal it could ma...
