Thanks for all the good words about Belka! Now new version of Belka is available - Belka DX. I would be glad to answer any of your questions about it!
Hello, I would like to ask, what is maximum bandwith on IQ output for possible processing signal in soundcard for panadapter or IQ recordings?
Thanks a lot

Greetings Alex! Thank you for communicating with BELKA-DX buyers and interested hobbyists here.

Interestingly, I used my PayPal debit card for buying the BELKA-DSP and now the BELKA-DX from your site. Maybe your country's regulations consider PayPal's card as a bank card, and allow it to be used. Not only did the transactions process successfully, I did not have to confirm the purchases through a security inquiry or similar. It was all very smooth and quick.

A question--will you be emailing purchasers when the BELKA-DX speaker accessory/modification is ready for purchase? I'd be happy to write a SWLing Post article about availability if you'd like me to announce it through that site.

We will inform all the Belka-DX users that speaker kit is available as soon as it happens. Hope it will be in December. I'd be happy if you write an article to a SWLing Post. If you have such desire, I'll highly appreciate this.

Well, I just received my Belka-DX today and I am IMPRESSED! I have power lines across my back yard, high voltage transmission lines 2 streets over, and a 60kW AM broadcast station a few miles from my house. This little radio cuts through all of the noise and I am pleasantly surprised. I have only had about an hour to play around with it, but I can receive San Francisco Aero as well as HF-GCS traffic sitting on my sofa. The menu takes a little bit of time to get used to, but not difficult by any means. Of course, this is not a $1,000 HF rig with an LP on a mast, but I can hear stuff on it which is more than I can say for just about any other portable receiver I have owned.
Thank you Alex!!!!

No issues using my card for the purchase. If you are concerned, I think some banks now will give you a one-time virtual card number for purchases. Might be worth investigating.

Hey there. Belka DX with built-in speaker or back cover with a speaker (for those who have already purchased Belka DX) is available now at our store

We now have a wiki page for this radio, viz.


It's a good start, but can use some fleshing out on how the I/Q output is used; what connections are needed, programs you can use, restrictions (up to192 khz - but what limits this?) and more. There are YouTube searches, but there are many more combinations that I didn't list....Mike

You may use any stereo shielded cable and such programs as Power SDR, HD SDR and similar programs. We're preparing documentation necessary for using of IQ output. Hope it will be ready soon.

Hi, Alex -

I ordered the Belka DX via your website earlier this month; it was a nice, easy process. Is there an online way to check shipping status?
I ordered one last week. No issues on the website. Chrome translated it well.

I'm really looking forward to this little radio. When I'm in the house and don't want to use headphones, I'm going to feed it into the line input of my CCR3. It should sound great on that big speaker.

What about the Belka DX and the use of an external antenna? It seems all the write-ups and reviews I've seen have all been with the included mini-whip antenna. I already have my share of portables (Elite Satellit, PL-660, ATS-909X, GP5-SSB) and one lugable (2010).

The Belka works really well with an external antenna on its BNC connector without overloading and there are videos showing this. In order to achieve maximum performance out of the whip its input impedance is not the typical 50 ohms. So there will be some mismatch when connecting it to a larger antenna but this will be compensated by the added gain provided by the antenna to the point that you will find it convenient to apply a bit of RF gain reduction to reduce the noise.

Appreciate the reply. This is a tempting piece of kit for someone who really doesn't need something new.
Yes, you already have other portable receivers, but this one doesn't look like anything else. It's so small and light that you can carry it in your pocket and then it's an SDR. You would be impressed. I ordered it in February 2020 from belrig.by without any problem.

I just ordered mine (w. Speaker and feet) from Boris.
This RX seems to be quite unique.
Can't wait to get it.
