*(33.333 must be replaced by 33,000. Antennas need to be glued from the outside to the side plates)

There are ICOM2 clones with the same manufacturing errors. You can understand this by the amount of memory or if R195 = 0kom

Such a board has exactly the same errors. R119 is installed 10kom instead of 1kom. This disables one memory bank.

Test and feedback:

Reset switch works, resistors replaced, serial changed. Icom now sees 256 memories, managed to update ICOM Next to version 03.15.04. Now icom starts up faster.
