Alternatively remove the insulation from the wire feeding Pin 1 then solder to the wire the
flying lead from the converter and apply insulating tape to protect the connection.
STEP 4
Connect power & a speaker to the receiver, power it up and test. Sensitivity should be far
better than 1uV (-107dBm) for 10dB S/N on AM and 12dB SINAD on NFM.
Airband converter: Guaranteed frequency coverage is 108 - 146 MHz (airband & 2m
HAM bands).
Marine converter (general): Guaranteed coverage 146 - 165 MHz but likely coverage is
108 - 165+ MHz (the top range accepted by the AR3030 microprocessor being 173.99999
MHz).
This means that the marine converter will also cover the 2M HAM band and VHF
airband. However, due to the wider frequency coverage there is less band pass filtering
incorporated than in the airband version of the converter.
Refit the bottom and upper case halves remembering to plug the speaker lead back into
the RF PCB (close to the external speaker socket). Remember that the side case halves
use cheese-head screws and the upper lower surfaces use countersunk screws.
