Re: VFO & LO for dummies

Hello Paul, There should be no difference in signal power between Low IF and Zero IF modes. One thing to be aware of though is that the IF bandwidth will be different. So for example, if you have set your sample rate to 8 MHz in zero IF mode and your LO to 4 MHz, the spectrum between 0 and 8 MHz wil...

Re: VFO & LO for dummies

Hello folks, Apart from the lack of a DC spike, there are no fundamental advantages of LIF over ZIF. There is no difference in noise performance or overload performance. The differences that Mike2459 at LF are all caused by the different frequency plan that is used in LIF mode where the synthesizer ...

Re: SDRuno 1.23 with hackrf one

Unfortunately, we don't even have sufficient resource to cover our current backlog of development work in a reasonable time frame. We would like to get around to enhancing the ExtIO version, but it is not easy as there has been a major branch in the code base and many of the features of the RSP vers...

Re: SDRuno 1.23 with hackrf one

Hello paddel57,
The maximum sample rate supported in the ExtIO version of SDRuno is 2.5 MS/s. RDS is also not supported.

In the RSP version of SDRuno. DC offset compensation is implemented in the API which you will not be using with the HackRF.

Sincerely

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

OK, I have been watching this thread with a growing sense of dismay. Andy (Chief software developer and SDRplay Support) has been genuinely trying to understand what it is that people have been so upset about- apart from the fact that we have not yet managed to produce a fully fledged equivalent to ...

Re: Access to raw data of RSP1

I/Q data can be saved into a .WAV file format using SDRuno. This has been processed by the API, but it is possible to use SDRuno to turn off features such as DC offset compensation and I/Q correction that are implemented within the API.

Re: Spike on 120.000 mHz

All RSPs use a 24 MHz clock, so 120 MHz is the 5th harmonic of the reference clock. You will always see spurs at harmonics of the clock and odder order harmonics tend to be stronger than even order harmonics. All radios will exhibit this effect due to finite cross-talk isolation. The Xtal oscillator...

Re: SDRuno Unable to tune above 412MHz

This is a bug that only occurs if you select Gain mode. It does not occur in Gain Reduction Mode. It also only occurs at the lower gain settings. The bug will be fixed in the next release of SDRuno

Re: Bad Experience so far.

Hello ilektranik Jon Hudson had a missed call from someone in Nashvile, Tennesee at 1.39 am UK time this morning, but no message was left. We are not sure whether this was from you or not. If it was, we don't understand why you did not have the opportunity to leave a message, but there is an active ...

Re: Bad Experience so far.

Unfortunately, the posts and phone call were very late/middle of the night UK time. I don't think this customer was necessarily aware that this forum is moderated from the UK. We will be reaching out to him in an attempt to resolve his issues.
