    Hi Derek
    The unit is only tidy on the outside :) using the ILI9341 3.5" with adafruit lib, has lots of nice fonts to choose. The serial interface does generate RFI though.

    Hi Derek
    I have your audioSDR running with good SSB reception. I compare to the RSP1A. AM is not so good, odd 1kHz noise on top of signal.
    Now looking at signal strength and panadaptor next. Any...

    Now have some audio! not sure what fixed. Added SDR.init() and toggled SDR.setMute(false).
    Is getAGClookup(int); the correct function to read AGC level?

    Hi again!

    Have loaded the audioSDR code, pretty sure all the functions are setup correctly but no audio output, not even noise. I used BareBonesWSPR.ino as starting point.
    I'm happy hardware...

    Hi audiomath!
    I used the adafruit library for controlling Si5351, will see how this controls the PLL and dividers. Thanks, very useful info.

    Hi
    A nicely presented audioSDR project, I'll begin implementing and try.
    I presume this is still using the weaver method? My current setup is the basic phasing type which is ok but needs more work...

    Ah, thanks for the link. A lot of comments there.
    General opinion is that the device is good for SW receivers. It's true that the PLL's are slow to lock, so this should reflect when tuning, but I'm...

    Hi Frank

    I am assuming the Si5351 behaves similar to softrock Rx (Si570) which i have played with and found tune stepping to be somewhat clunky, time to settle. These are dual PLL's with up to...
