[Icom] Mods for ICOM 756 PROII

Tue, 21 Jan 2003 22:24:34 -0500

Some pieces of ham gear are NTIA compliant. My TS-940S is compliant
because I added the SO-1 High Stability TXCO option when I bought new.
At the time I wasn't thinking NTIA, I just wanted to ensure I had the
highest stability possible. I lucked out. My IC-706MkII is also
compliant as I added the CR-502 High Stability TXCO option when I bought
that new. The IC-756ProII comes standard with the High Stability TXCO so
is compliant without the need to add any options. Very little ham
VHF/UHF gear is NTIA compliant, I have commercial gear (Motorola and
Tait) for VHF NTIA operations.

Here are a couple links to help sort out the NTIA issue:
