Frequency in SDRUno and hardware drift apart
Posted: Thu Dec 29, 2016 2:19 pm
Bought my RSP2 Pro from MLS yesterday, spending today getting into it.
A couple of niggles so far, the most important being that the frequency displayed in SDRUno seems to get out of step with the hardware.
At startup, all is fine, but during the process of changing frequency through a combination of typing in directly or using the mouse to point at a peak in the spectrum (and I'm not sure when this happens or how long it takes), I find that the software and hardware don't line up anymore.
When encountering this today, I was trying to tune to Shannon Volmet on 5505kHz (having tuned in fine earlier) and heard nothing. I exited SDRUno and reloaded, the software still showing 5505kHz, but this time I could hear the broadcast.
In other circumstances, I've spotted a peak in the spectrum and clicked it to find an English language broadcast that I know for sure is on a different frequency to that shown in SDRUno (and verified no such station is on the shown frequency using a different receiver). Close and reload SDRUno and the station is not there, retune to the actual frequency using the keyboard and the station is there in its proper place.
It doesn't happen all the time, but you don't know when it does - so if I hear nothing on a particular frequency, I don't know if there really isn't anything broadcasting or if the hardware is actually tuned somewhere else.
The other niggle is when the main window opens, a number of the buttons including Play are rendered in free space off to the right of the window. If I move or resize the window, the buttons jump back to where they should be inside the window.
