This reduces the pressure required to key the mic to about
half or less. (Sorry I do not have any measuring instruments). Perform
at your own risk.
- Turn off radio. Leave Mic connected to radio and radio connected
to power. This will reduce the chances of static discharge blowing the
IC behind the cover. Ground yourself.
- Remove the 3 screws from the back of the mic and gently remove
cover. Inside the large PTT housing you will notice a spring with
BLACK foam in it as well as a piece of RED foam that comes in contact
with the actual PTT micro switch.
- From the bottom of the PTT pull upwards until the PTT housing
comes out of the MIC housing. Take care not to damage the RED foam.
- Pull the spring with the BLACK foam out of the PTT housing. Store
in a safe place as you may not like the difference it makes.
- Carefully reinsert the PTT housing, again taking care not to
damage the RED foam.
- Replace the rear cover. DO NOT OVER TIGHTEN SCREWS. Test PTT. Test
APRS messaging from Keypad. This will verify the IC has not been
damaged.
Hope it works for you!
