for 40 meters.
Since those crystals are reliable, I suspect that you have a problem
with the Pre-Mixer Bandpass Filter.
You need to have at least 200mV peak to peak signal (70 mV measured with
an RF Probe) to prov
Hello,

aligned the 20m filters, but on 40m there is very little noise, and the noise
does not change when there is an antenna connected. However, I have received

I have inspected the
Check to be sure that you have set the correct 30-meter band edge (10.0
or 10.1, depending on your chosen VFO range). See the manual's
instructions for setting the Bx parameters.
Some years ago I had a problem similar to your first one. It turned
