Subject: Alinco DR-430 Extended TX modification. SB ALINCO @ WW $DR430.TX DR-430 Extended TX mod. This is the Alinco DR-430 Extended TX modification. This modification will expand TX coverage to 403-499 MHz. Please follow the steps and do the work CAREFULLY! This modification works great in my rig and I assume this modification will work on almost all 430's (no warranty implied). 1) Unscrew the 3 small screws on the top cover. 2) Gently remove the top cover. 3) Cut the little loop wire (blue) that's located just behind the display, 2" left from the Power button. 4) Reassemble the radio. 5) Reset the radio's CPU by turning power ON while pressing the F key.
