Omni VI 2nd order IMD Mod

[John Morris]

Would appreciate hearing from anyone who ever installed the subject 
modification in their Omni VI.

This mod involved changing 2 resistors on the BPF/Front End board and was 
supposed to improve 2nd order IMD from 40 dBm to 60dBm.However, TenTec 
advised that "precious few hams in the U.S. would gain anything from 
improved 2nd order IMD".

If you installed the mod:

1. Degree of difficulty?
2. Any noticeable improvement or difference?
