Re: Calibrating SDRUno

'An eighth of an inch' doesn't mean a lot Max, as it depends on what span you have selected and any zoom you are using. Can you say how many KHz it is? The RSP2 and 1a are usually very close to their claimed frequency (with in a few hundred Hz at VHF) and anything bigger than this may indicate somet...

Re: Looking for a Wellbrook LF1010

It's worth remembering that the LA1530 works down to at least 20 KHz. There's a group of 4 or 5 data sigs around 20 KHz that come in well here in NW England. I suspect the response is dropping by this point though, so if you need to hear down to 10 KHz, maybe the LF1010 would be better. I've attache...

Re: SDR PLay RSP2 Characteristics

I can't answer any of your questions except the reference frequency. It is 24 MHz on all models.

Re: New to this and my RSP2 keeps switching antenna inputs

Kenny - be prepared to spend some time getting used to it. The RSP's are all fine receivers which will receive just as much as your analogue radios. In many ways they are better, as you can set filter widths and gain levels to suit your tastes with far more flexibility. I was just like you - old-sch...

Re: First setup VHF 118-160 MHz

Neil The RSP's use SMA antenna connectors. If your antenna cable is big & heavy, I'd recommend an adaptor lead rather than a rigid block adaptor. This will take the strain off the system. There's a company called Sinequanon that do ready-made leads and their prices are reasonable. I don't know w...

Re: Saving screen layout

The method of saving your workspace has changed. It's detailed on page 13 of the manual, available via the OPT menu.

Re: circuits

Basically yes. The chipset is the Mirics in all versions but the antenna signal routing is different and the RSP-1a has extra (and better) bandpass filters. Also the RSP1a makes use of a hidden feature which can use an extra 2 bits of ADC resolution, but I wouldn't expect this to make a big differen...

Re: Sangean Portable Antenna for RSP1A?

Remember that the Hi-z connector is best when using a short-wire antenna. It also has by far the best response at LF if that is your interest.

Re: sdrplay1

Welcome. The RSP's are all sensitive and well-performing receivers, and most performance issues are due to a bad choice of settings, poor antennas or incorrect operation. A good read of the manual and getting basic operation right before trying all the bells & whistles is recommended. When you s...

Re: How to change Freq step

If you are using SDRUno, there is a bug which erroneously selects 100 KHz (instead of 100 Hz) when in LSB. You can correct it by following the normal procedure for step size selection as per the manual. The manual is available via the OPT menu. Or you can hover the mouse over the relevant digit in t...
