Model 6 Receive Sensitivity
Set the Model 6 FFSK receive sensitivity by performing the following steps See Table 8
for initial jumper settings. See
Table 9 for potentiometer information. See Figure 29 for
locations.
Tip
If there is an external control on the radio transceiver that allows
people to alter the receive audio level going to the Model 6, this
control must be locked in some way after the adjustments are
made. Changing the level of the receive audio presented to the
Model 6 can compromise the decoding of FFSK data packets.
