Notes:
1.
Channel 6 beat is the interfering product of fRFpix, fRFsnd - fOSC of channel 6 at 42 MHz.
2.
Channel A-5 beat is the interfering product of fRFpix + fRFsnd - fOSC of channel A-5,fBEAT = 45.5 MHz.
The possible mechanisms are: fOSC - 2 x fIF or 2 x fRFpix - fOSC. For the measurement VRF = 80 dBV.
