[Elecraft] Sub Band Speakers on 15M Band

[Don Wilhelm]

Irwin,

Do you have the Main tuned to 20 meters and the SubRX tuned to 15 meters?
If so, the 20 meter Low Pass Filter is selected and will cut the 15 
meter signal to almost nothing.
The same thing can happen on other band combinations.  To avoid that 
problem, either set the SubRX to a band lower than the MainRX.
Or, use the AUX antenna input for the SubRX (that avoids the LPF).
