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...

Re: Spike on 120.000 mHz

One of the RSP's converter oscillators runs at 120 MHz, so it may be that. Not sure about the RTL stick - probably something similar, maybe a clock oscillator harmonic.

Re: Bad Experience so far.

Don't feel bad. My experience with the team has been nothing but positive, with questions answered within hours and bug reports acted upon quickly. It seems you have been extremely unlucky.

Re: W6LVP active loop antenna

Good luck with the new antenna. I've been using a Wellbrook 1530 for many years and it has literally saved my hobby. The noise on my wire antennas (and the mini-whips I have built) is horrendous, but the loop just ignores most of it and it has dropped from s8-9 to s1. And as it's on a rotator I can ...

Re: Bias-T powered filter and an Active Antenna on Port B

There will only be a problem if the filter cannot pass DC through to your active antenna OR the filter has a DC path to earth, which would short the DC and possibly damage the bias T. Can I ask is the filter a MW rejector or a MW bandpass filter? And what band are you hoping to listen to? Cheers Andy.
