Eric & All: Here's XJ on 137.78~ kHZ with a 50dB pad on the output port of the HD-1420....still greater than
10 dB above the background noise in EN90xn.

No copy on MP at that 50 attenuator level, but
Mitch's MP signal is copyable here with 40dB of IF attenuation.

ARGO tracks dBs well as Eric was -31 with no attenuation and -80.6 with the 50 dB pad in line
