Kenwood TM-D700A (TM D700A TMD700A) MC53-DM MIC PTT Spring tension MOD

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.
  1. 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.

     
  2. 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.

     
  3. 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.

     
  4. 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.

     
  5. Carefully reinsert the PTT housing, again taking care not to damage the RED foam.

     
  6. 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!
