[1000mp] FT-1000MP Mk5 Field Problem

Mon, 17 Jun 2002 09:05:04 -0400

Hi Bob,

Many Thanks for your reply.
Well I love to operate full QSK CW and always enjoyed it with
my trusty TS-940.  I guess I will have to get used to the Field but
I am disappointed that Yaesu didn't take the trouble to clean up
the QSK operation on these rigs.  Other than that the Field is
a great rig...
