Elecraft makes a XG1 Receiver Test Oscillator which puts out a 1 uV and 50
uV test signal on 7040 KHz. The little oscillator is not very expensive and
is an excellent stable signal source for adjusting the roofing filters on
the Orion. They should be available directly from Elecraft.

It seems that one really needs a stable steady
signal, both in frequency and level to do this job.
Short of homebrewing a crystal calibrator (since
these seem to be few are far between these days,
even on ebay), what do people use for a good steady
signal source for this job. Off the air signals
seem to have enough QSB to be a problem and without
a second rig to use for a source, I was curious
what other people used...
