Re: What is on everyone's SDRplay V2.0 wish list?

The only one that springs to mind is much-improved front-end filtering. The images of FM and DAB that 'get in the way' are numerous, wspecially around the 250 MHz satellite band. External filters can get around this, but it's messy. Some tight up-front filters would be most welcome. Oh, and two sepa...

Re: Airband

I have no images, but very low signal on airband. Im using a Airband vertical antenna 5/8. On my single RTL, the airband signal is great, bur on sdr-play is poor. That's strange. I listen to airband occasionally and find the RSP just as good as my AR5001d receiver, in fact it can be better as I can...

Re: Airband

The SDRPlay has good sensitivity across its coverage. Its weakness is image responses, usually in the form of unwanted FM broadcast and DAB appearing at unexpected places. It's due to the conversion regime. Try selecting a different conversion frequency from the advanced menu, this might clear it. I...

Re: FM stations appearing in many bands

Some of the unwanteds are due to the conversion oscillator (just like a normal superhet), but others a traceable back to harmonics of the sampling frequencies. Sometimes you can make an unwanted response shift out of the way by moving the centre frequency (I guess this moves the LO frequency), but o...

Re: FM stations appearing in many bands

John This is a known phenomenon with the SDRPlay, as it is with other types of SDR. There is no way around it except by using an Band 2 rejector filter in the antenna feed. You may be able to move the FM responses out of the way by choosing a different sampling rate or another LO frequency (look und...

Re: Where is the bfo ?

If the Tecsun has a 'bfo' control, you've got used to adjusting that for correct voice pitch. In common with most other 'serious' receivers, the SDRPlay does not have a BFO control, it is fixed. Fine tuning is done with the main tuning control in small steps by hovering the mouse over the 10 or 100 ...

Re: SDRuno opens in tiny nonexpandable window

I may have the wrong end of the stick, but it sounds like you are describing the 'start' window that appears when you first run the software after installation. From this small window, you open up the main waterfall/spectrum window and the control panel. Together, these can fill the screen and you c...

Re: Another strange one.

good morning Hombre.
I'm not complaining. We all need to report bugs so that they can be dealt with. If the team does not know about them, they cannot fix them.

Another strange one.

I recently spotted this when tuning around MW. When tuning below (about) 3 MHz and with a bw of 0.2 MHz, if I press the 'perf' button in the main window I get lots of spikes appearing, spaced just a few KHz apart. This behaviour lessens with increasing frequency and is gone by 5 MHz or so. It is ver...

Re: Odd behaviours spotted so far.

I've tried that, Jim. I first increased it to -40 and that seemed to stop it, but it started again later. So I took it the other way and once again it stopped...then came back. I seem to recall that in its early days, the SRP had this problem with SDR# but was corrected with updates to the EXTIO file.
