Re: VFO & LO for dummies

You are right on the definitions. LO LOCK does exactly that. It locks the LO frequency so now when you scroll with the mouse wheel you will see the VFO move up and down the spectrum, but the LO frequency does not move. So from the hardware perspective, nothing is changing. You are just selecting the...

Re: VFO & LO for dummies

One relates to the hardware (LO) - this is the centre frequency that is ALWAYS used by the hardware to tune to the chunk of spectrum you want to work with. The Sample rate defines the amount of spectrum bandwidth that you can see centred around the LO frequency. The VFO is a frequency that you can t...

Re: SDRuno 1.23 with hackrf one

I think he means 1.22 - that's the latest release.

Re: CubicSDR 0.2.3 released. How about updating links???

but if you only built a new copy of CubicSDR after a new release came out that would be a net improvement. There is no need for me to produce a build after a new release as it will be available on https://cubicsdr.com release page. I will keep the website updated with links to CubicSDR releases. If...

Re: CubicSDR 0.2.3 released. How about updating links???

I am genuinely trying to understand what is being asked. Up to now I produce Mac builds of CubicSDR (which we have no hand in developing) when I can, probably every few months. CubicSDR official builds are made once or twice a year. The code is updated on a weekly (if not, at times, daily basis) I'v...

Re: Does SDRuno Software Allow For Continuous Tuning ?

Also, please note that port A and B of the RSP2 are only spec'd down to 1.5 MHz - if you want to get good performance at VLF, you are better using the HiZ port.

Re: Does SDRuno Software Allow For Continuous Tuning ?

You have a sample rate of 2MHz and a decimation of 8 which gives you a total sample rate of 250kHz and the IF bandwidth is set to 200kHz. The LO is set to 342kHz, so you are just seeing the edge of the IF filter rolloff.

Looks normal to me.

Re: CubicSDR 0.2.3 released. How about updating links???

We provide the same support on non-Windows platforms as we have ever done. We have always maintained the API for developers to use on Windows, Mac, Linux, ARM and Android. We support SoapySDR which is cross platform and recently gr-osmosdr has been updated, which again is cross platform. CubicSDR is...

Re: Does SDRuno Software Allow For Continuous Tuning ?

If you are using a RSP, then the LO can tune between VLF and 2GHz without the need to press Stop/Start - if you are using other hardware with the ExtIO version of SDRuno, you will need to check with the hardware manufacturer on what their product allows/requires.
