I'm using the R820T based turners. The PPM values on these tuners are probably
relative to them. I have one that requires 48, and another that need 61.
I've gotten the scope tuned pretty close to the desired frequency, but it's just
not acting right. The Fine Tune slider does work. When viewing the spectrum scope, I can
see the dismal spike shift +-3k as you would expect. The scattered constellation cluster
circles around in 360 degrees from center while fine tuning as well. The Signal Gain
slider also functions properly as well.
I noticed the scope app seems to stutter quite a bit too. The osmocom_fft doesn't do
this running at high sample rates(2Mhz). Could this be the cause??
