Re: RR501 receives the rf signal, but won't send to other units

["Anand" <ardhuru@xxxxxxxx>]

I'm almost certain of whats happening, going by the symptoms and my
very similiar experience; there is a small transformer near the 120V
outlet that generates the outgoing 120 kHz, and also couples it to the
mains.

You could confirm this by checking your unit against the schematic
available at http://www.geocities.com/ido_bartana/

My bet is the winding in that transformer has opened up.
