The radio is on a chip. You put power in, RF in, get audio out. Everything is done by the chip. Your only job is to tell the chip what you

Hi Lamont, I have just ordered 10 x 500pf varicaps via ebay.co.uk to use in (I hope!) a varicap tuned indoor frame loop. They only cost 1GBP from China, of course. There were many other vendors

Maybe I need to refine my question a bit. The discuss was about if a radio is designed today, will it incorporate a receive chip.  It all started with someone saying Varicap availability is

All digital radios use DSP chips, but Tecsun's analog radio's also use an Integrated Circuit. Specifically, that I know, are the R-911 and R-9012. These use a CXA-1622B chip IIRC designed by SONY.

Recently I have purchased a large A/B audio switch box, this is being used for direct audio / signal testing of various radios. I have mounted this in a large case and have run two 3.5mm audio

Thanks Richard. It is something that I am really interested in and enjoying.-- Paul - Moderator UltralightDX

"Mostly" is pretty vague. The Tecsun line all seem to be built on the Silicon Labs, maybe better known as SiLabs, chips. Silicon Labs is a fine American company with operations all over. See the

Paul: Thanks for posting the article. I’ve been FM DXing since 2010 using barefoot Tecsun ULR, primarily a PL-606. To date I’ve logged 876 stations from across North America. I have tried using

I'm following a thread on a group with an argument about whether new AM radios are now mostly designed with a chip for the radio receive circuitry. Does anyone have a website with either a list of

Thank you, Gary!

Hello Igvitk, Litz wire and ferrite optimized for the MW frequencies really isn't recommended for SW performance. Especially in a sharp-tuning FSL antenna, going outside the recommended frequency

Hi all! I was trying to make 3 inch FSL antenna for MW band, but I ordered less than necessary of AWG 250/46 litz, and did not get the required inductance (just 180 uh instead of 350 uh). As a result,

Portable Ultralight Radio DXing Case - March 2020 - An Update After building my latest case, I found a couple of issues. I needed to protect the screens and cases of my radios and I also had an

Paul, I was keen on radio as a child, inducted into the hobby by my father from the age of about 6. Whilst still at school, I applied for a monitoring position at the BBC’s Caversham Park site.

That sounds very interesting and something I would have loved to have done. Paul -- Paul - Moderator UltralightDX

Just curious to see if anyone else here has made a career of radio listening. I have been doing it professionally for about 40 years. I started out when I joined the US Army Security Agency and
