@Kc7noa I created a Pothos layout a while ago for receiving my local FM radio statio at 103.6 MHz and re-transmitting it at 104.6 MHz. File (FM Re-Transmit 04.pothos) for download is here: https://hackaday.io/project/20500-cell-phone-signal-repeater-booster-femtocell

It worked pretty well except that the audio came out rather garbled. I’m kind of thinking that if my Lime was properly calibrated then the audio should come out nice and sweet. That being the case, could I manually adjust the I and Q settings in limesuite until that happened? Could this be a useful work around?

There was a patch for limesuite because the rx calibration would break tx calibration…
That might be what happened
