Hi Frank, take a look at the mixer and oscillator infos. There is a high
performance mixer , a SHF Oscillator ideal for the 13 cm band, and info about my
HF VCO , which was divided down.
1KHz -108dBc
10KHz -130dBc
100Khz -150dBc
Noise floor -155 dBc at the output frequency 45 to 75 MHz

What are you using for mixers these days? I want to look at h mode. Also I
find roofing filters are the IP3 limit not the mixers.
My RA6830 synthesizer is 40 to 71 MHz so I was looking at using a VCO at X2
or X4.
