This mod. was very straightforward and was finished within 1/2 hr.
Listen here for before and after audio (recorded on the ICOM 756proII -signal at 40db over s-9 with some overload):
Before the mod.....TX on 7027, sweep down from 7030 to 7025: Yaesu7027up30dwn25.mp3
(listen for the tell-tale machine gun, ticka-ticka-tick sound below and above centre)
After the mod.......TX on 7027, sweep down from 7030 to 7025: Yaesuclickfix7027up30dwn25.mp3
(still some overload, but the clicks are all but gone)
