ICOM IC-2720H MARS/CAP mod
To modify the IC-2720H for extended xmit (MARS/CAP), remove the two diodes shown in the drawing and picture.
The drawing shows a cluster of 8 miniature diodes and which two to remove.
My IC-2720H (US version) ONLY HAD THESE TWO DIODES INSTALLED. The other 6 shown in the drawing were already removed.
I took a picture of the area before I removed the two diodes.
As you can see in the picture, they are the only two installed in that 8 cluster area, remove them both.
Extended transmit freqs after removal are:
VHF: 136.000 - 173.995
UHF: 400.000 - 469.975
I removed the two diodes and powered up the radio WITHOUT reseting and the extended xmit was available without loosing any memories.
