Re: TV Rabbit Ears Works Well

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...

Re: Impossible To Install

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....

Re: Newbie coming to the party!!!

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...

Re: LNA for SW and MW?

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...

Re: TINY homemade UHF ant. WORKS

Connect them to the braid somehow and either let them dangle down (this will make the antenna more like a dipole) or make them stick out horizontally (this will make a ground-plane antenna). Those little V pieces sticking out aren't doing anything, they could be removed.

Re: Would wrapping the unit in AlFoil tape help shield it?

Well, there are many 'web sdrs' online. Some do only amateur bands, others cover 0 to 30 MHz. Hope the noise goes away BTW.

Re: TINY homemade UHF ant. WORKS

That's about the right length for ~450 MHz, but those little stubs aren't going to have much effect either way. I see you have nothing attached to the braid of the coax, so the antenna will not be working at its best. You need to make another two 6-inch lengths of wire and solder them onto the braid...

Re: AM broadcast stations on evry band to 30 MHz?!

Heinrich
The early SRP's used an F-type connector. I bought my SRP early on and it was in a blue & white case with an F connector for the antenna. I actually prefer it as it is far less fiddly than the SMA type!

Re: S meter adjustment ?

Main panel (the one with the 'play' button) > SETT (button in top of frame) > CAL.

Most people find the meter reads too high and a setting of -15 to -20 is about right.

Re: Signal mirrors all over the band.

Have you tried choosing another converter LO setting? If these FM stations won't go away no matter what you do, an outboard FM rejector is the only answer.
