[1000mp] Key Clicks Solution?

Sun, 1 Feb 2004 14:14:39 -0500

Hi Harry,

I want to do the Inrad keyclick mod to my MK-V Field!!!
I understand that Inrad does not have instructions to do the
Mk-V Field.  Can you tell me how you did the Field mod???
The component designations seem to be different between the
MK-V and the MK-V Field...
Thanks in advance and 73,  Ted  K2QMF
