[TenTec] Paragon problem

[Wade Staggs]

*Far from being an Expert myself, The first place I would look would be the
RX High Pass Filter Board ( 81330 ) At the Antenna Input to the High Pass
Filter Board, there are two LC Coils and a Diode ... Any of which could be
Shorted or open in the case of the LC Coils. You should be able to inject
signal or an antenna input on each side of the High pass Filter Board. I
would use a Clip Lead and touch my Antenna to the output connection from
the board and see what happens. The High Pass Filter board uses Switching
Diodes to select the correct Filter for each Band. I am believing that like
Ivory Soap, 99 44/100s percent sure that the problem is somewhere on the
High Pass Filter Board.*
