So I remeasured my ubitx this time with my oscilloscope FFT.? Not sure how accurate those are?
It shows a lot less spurs but does still show a spur only -20db down when transmitting at 7.150MHZ somewhere around 21.5MHZ or so (I didn't zoom in too far so plus or minus ~500khz .? (I tested connected to the scope through coax -40db attenuator).
It tends to confirm of the rtl-sdr which saw one about -30db down or so.? I didn't notice the large amount of IMD within 750khz range as I did with the RTL-SDR though there was a lot of noise (might have to up the averaging to see if I can filter that out).
