If I'm reading it right I think you are tuned to 1440 MHz, Missiletech.

The spike in the middle is the local oscillator and is normal, but it should be well-suppressed (ie only small) when everything is working normally. As for the other problem, I wonder if your PC is lacking enough 5 volts on the USB?

It's also a good thing to use as little RF gain as possible, rather than going for max. This will reduce the effect of strong local signals. Another way is to choose a small RF bandwidth (low sample rate) so that the interfering signal is off-screen and outside the IF b/w. As Glovisol says, the new ...

illlm - the DAB notch filter will only appear if you have the RSP1a or the RSPDuo. Other models do not have the hardware to implement it. My RSP2 only shows notches for MW and FM.

I raised this issue yesterday after I discovered that I could no longer fit the RX Control, Main and Aux SP windows across the top of the screen without serious overlap. I contacted HQ and the bug is now on the 'to do' list. Great service once again.

It's amazing. There's a temptation to think that LW signals are very stable and not affected much by conditions because of their low frequency, but things like this make you think again!

Wide FM is too wide for these PMR digital modes. A narrower setting of NFM 12 KHz or so should do the trick. WFM will let through adjacent channel signals which will corrupt the one you want.

Excellent!

I use SDRUno on a mid-spec i5 windows 8.1 laptop. It has an Intel processor at 2.4 GHz and 4 GB of memory. I find it runs just fine right up to the full bandwidth. I've never tried running more than one VRX though. My old P6200 laptop (2.1 GHz with 1GB memory) used to choke above 6 MHz b/w but was p...

I can't understand what's going on here. Perhaps it's time to go to the support centre and open a ticket. The developers are very friendly and will sort it out quickly.
