Internal Jumpers
There are 9 jumpers inside the RX SHARE Jumpers H1 through H9. Access to the inside is done by
removing the four Phillips head screws that hold the case together.
Audio Impedance Jumpers H2-H9
The audio impedance jumpers select different winding configurations of the audio isolation
transformers to vary input and output impedance. Most radios and headphones will not require
changing jumpers H2-H9 from their default 150 ohm position. If the headphone audio is loud
enough and does not require turning the receiver AF GAIN controls to an extreme position, you do
not need to move the jumpers.
Jumpers H2 & H3 are for Operator 1 output audio from the RXSHARE.
Jumpers H4 & H5 are for Radio 1 input audio to the RXSHARE.
Jumpers H8 & H9 are for Operator 2 output audio from the RXSHARE.
Jumpers H6 & H7 are for Radio 2 input audio to the RXSHARE.
