I'm using an SDR Play and slowly getting to know it. I managed to listen to digital radio in Band III OK but now trying to see digital TV. I downloaded Mirics software. Although Mirics has a console f

Hi Simon Yes, pretty rural, north of Rowridge at BH23 8DU I’m receiving the 522MHz DTG-3 signal perfectly. There’s a similar mux on 498MHz also DTG-3 carrying BBC1 etc but cannot get that one I initia

I tried an old portable TV aerial Jim. One of those where you can adjust the angle and length of the elements and adjusted it for best signal strength at 495MHz. A rescan gave me 140 channels so that’

I've been Investigating spurious responses using a long wave broadcast. Below for comment and for general interest are the results I'm using SDRConsole (V2) Build 2381 and a new SDR-Play location BH23

Hi Bernard It’s a wooden cross with three square loops on a wooden pole 20 feet high One loop wound for long waves (about 3 feet side), one for medium waves (about 2 feet 8 inch side) and one for 80m

Thanks for the info Rob I’ll take it into the workshop where I have a spectrum analyser and some half decent test gear. I’m a little unsure though of my use of a varactor diode for RF amp tuning as th

I'm near Bournemouth in the UK and, after experimenting with my new SDR Play and V3 of the excellent SDR sotware with various pieces of wire, I connected up my wideband discone aerial. Much better res

I noticed an audio problem Simon. V3 build 570. With the aerial unplugged from the SDR Play there’s always a spike at the centre of the screen. Noise floor -125dB, spike -95dB. If for example 198KHz R

Hi John I’ve been building PCs for over 20 years and use a local importer, Spire. http://www.spire.co.uk/ I notice that they now only supply Asus and Asrock motherboards which might suggest these are

I thought I’d send a picture of a shot of the medium waveband here in the UK just as it was getting dark. You can see every single channel in use even though some of the transmission powers are exceed

Is the power supply OK? Why not treat it as an ordinary radio? Plug in a signal generator and check sensitivity that way but sounds like the connection between the circuit and its aerial plug is open

I’d still check the connections at the antenna connector inside just in case there’s a dry solder joint or a short circuit Chinese stuff often isn’t soldered properly Allan G3PIYT From: sdr-radio-com@

Hi Barry I’m new to SDR but decided I’d spend enough money so I wouldn’t feel disappointed with the results. On the grounds you get what you pay for I decided on the SDR Play rather than a cheap dongl

Why not fit a small tuning condenser and a coil in a tin box and null the offending signal… You can basically use the receiver as a spectrum analyser to get the best L/C ratio Allan G3PIY From: sdr-ra

I tried a small 500pF tuner in series with the first coil I picked from the junk box (40 turns on a quarter inch former), a couple of 20pF caps for in and out and a pair of BNC sockets. It worked arou

If the problem is that your USB socket can’t supply enough current, maybe try another port on a different hub. Your computer should have a couple of hubs on the motherboard. Maybe try it on a laptop?

The answer’s probably elementary, but can someone explain why I see the broadcast on 198KHz (much attenuated) sitting at 58KHz when I’m tuned to the Time Signal on 60KHz if the view shows 60KHz on the

I see Doug has already replied to your noise spike problem Joe. If you look on the following page you’ll see something similar to your problem http://www.radiomuseum.co.uk/emc.html In this case the ma

Quite right Brian I’ve been working with computers since 1965. Two things though… first steer clear of any products that are not recommended by a friend otherwise you’ll end up in trouble. Ensure that

You should have noticed the custom install option Alex although it took me a couple of attempts before I noticed it. There were something like 20 optional programs and features which I declined to ins
