[R-390] (no subject)

[Johnsay Johnsay]

Hi All:
I would like to introduce myself to the group...    I've have had several receivers of the Collins family pass through my hands over the years (R-388,  R-392 and R-390A also 52S-1,  75S-3 and 75S-3B).   
I've been monitoring the group for a while and I've been pleased to see some really great information passed along.   Currently I'm working with an R-392 and a recently 
acquired Motorola R-390A.  So I may need to tap into to the assembled wisdom...
John,  W8KX
