Hi John. I love loops. Tuned ones are nice to twiddle but the constant re-tuning as you move from band to band can get tiresome. Wideband ones are more convenient but need an amplifier as the loop produces a lower signal than a tuned one(I use a Wellbrook loop). When I was homebrewing loops, I found...
The block diagram and cct diagrams of the RSP-1 were published and I printed them out and filed them with the manual. As a retired electronics engineer I like to have these things. Are there any similar documents for the RSP-2? I'd love to see the changes to the front end filtering, antenna switchin...
Hi Larry. It's hard to think what may be happening, but a common mistake is to use 'reverse' SMA plugs. These look like normal plugs but they don't have a pin. Using these causes zero signal on HF and weak signals on VHF/UHF. This has caught out a number of people. Also make sure the AGC is ON (set ...
I think it should be made clear that the A and B antenna ports are NOT suitable for VLF (sub 100 KHz). I've just set my new RSP2 up, and after a few tests it is obvious that as the frequency decreases, the sensitivity via these ports falls away steeply and if the gain is increased you just get more ...

Hm, I would say most of the wishes for the RSP 1 have been recognized and the result is the RSP2. Only thing I don't like with the RSP2 is the high impedance antenna input for VLF and LF. I am using an active antenna there which has a 50 Ohms output. So the recent buyers of the RSP1 have funded the...
It's a shame that the MW notch is not operative on the hi-z input. I do quite a lot of listening in the sub-500KHz area and MW stations do cause images and stuff in this part of the spectrum. I've still ordered one though. I'll just knock up another LPF.

I took a 'rabbit ears' TV aerial with me on holiday, along with my laptop and my then-current toy the FunCubeDongle Pro+. I was into UHF satellites at the time and if I set the lengths of the ears correctly (one quarter wave each), reception of the 250 MHz sats was very good. At full length they wer...

Odd. I find SDRUno the easiest I've ever tried. Just download and install and it works - no extra drivers or EXTIO files, just so simple. And I speak as someone who always falls victim to any and every installation bug out there....
Welcome aboard. I'm sure you'll be impressed once you've got used to the various features. As for your aerial, is it tuned or wideband? If it's wideband you may see various images or 'ghost' signals appearing where they shouldn't be. A tuned loop would reject these, but a wideband one will let every...
Hi HB There's an additional LNA above 60 MHz, but there is a switchable LNA on the tuner chip that works on LF/MF/HF. Whether it benefits reception probably depends on signal level and your local noise level. I've just had a fiddle around and it is of no use on MW as signal levels are high anyway. O...
