Re: Anyone ? - An SDRplay Radio Used As The Core Module

Hi Paul. I did something like that with my original RSP1. I took the RSP's PCB and fitted it into a small diecast box with a homebrew filter bank. From memory I had: LPF for < 100 KHz LPF for < 500 KHz LPF for <1.7 MHz BPF for 160m amateur band HPF for >2 MHz for general SW listening. You may have g...

Re: RFI

Hi again Paul. Closely-spaced spikes are often the product of computer displays, TV's and data transfer devices like PLA's and USB cables. First, eliminate your own stuff by unplugging everything, or if you can run your setup on batteries, turn off the main breaker. How is you antenna fed? Hi-z wire...

Re: SDRUno squelch question

I suppose it's a matter of taste, but to me it seems wrong to use squelch on SSB. SSB is generally a DX.weak signal mode and it would be a very tricky thing to set up so it opens reliably on a weak SSB signal.

If you haven't already, maybe it's time to start a support request with the team.

Re: Does SDRuno Software Allow For Continuous Tuning ?

Paul WB5AGF. If you use the 'band' buttons, the LO will lock at the centre of the chosen band and the sample rate/decimation will be set so the band is framed properly. With the LO locked you cannot tune out of that band. If you want to tune freely, the LO lock should be OFF. With it off you can tun...

Re: Does SDRuno Software Allow For Continuous Tuning ?

I can't make that link work, Paul. But I tend to hover my mouse over the required digit and click to tune and then use the mouse wheel to move up & down. Maybe that's the difference.

Re: Does SDRuno Software Allow For Continuous Tuning ?

That's interesting, Paul. I do a LOT of scudding around the NDB band and lower, but I've never had this happen!

Re: Does SDRuno Software Allow For Continuous Tuning ?

Just leave the LO unlocked and tune up or down as required. You should be able to go anywhere without any locking or unlocking being necessary.

Re: Does SDRuno Software Allow For Continuous Tuning ?

AFAIK, there is no requirement to stop anywhere and re-calibrate. You can just keep tuning and the LO will position itself as you go.

Re: Access to raw data of RSP1

I can't answer most of your questions but I do know that the RSP's are tuner-based hybrids. That is they use superhet-type techniques to produce a low IF (or zero IF) signal which is then sampled. Link to schematic: http://www.sdrplay.com/docs/SDRplay_RSP_Schematics_r2p3.pdf The MSI1001 is a tuner c...
