[Elecraft] Heil Proset w/ K2

Tue May 6 22:46:00 2003

Mike, Ron,

Thanks for the responses.  They've given me useful information. =
 I'm still hoping to get a response from one of the Elecraft duo=
 to get the "official" word on accepted mods to make the Proset=
 work with the K2.  I'll post any relevant private communication=
 that I get directly to the board.  Mike, what's the Kenwood "red=
 connector"?
