@W5VO yeah, I read something about that too, and some people claim that when you install the 100mhz option they will be tuned to 100mhz and everything is fine... I was mostly wondering if there are some quality/calibration things that were not passed so something gets the 50mhz stamp.... I saw no credible source yet that compared a "real" 100mhz with the hacked 50 one
