Dear Dave & Trev,

Somehow I missed Trev's reply on the reflector, Thanks Dave for including
it in your reply.  I have to reply directly, not on the list when I'm at
work.

Let me thank you fellows for your time & effort giving me your thoughts.
You seem to be with the VAST majority of the consensus, i.e. in good
company.

I do believe your emails have "turned the tide" for me and I now know my
future course of action.

Thanks Again,

TR WB6TMY
S/N 0838

P.S. If one of you could forward this reply to the list, it might help to
set this thread to rest.  Thanks!  Otherwise, I'll post it at 7 PM when I
get home tonight.

Trevor is absolutely correct.  A Timtronized Ranger, for example, can
produce AM audio that anyone can be proud of.  If you're interested in AM,
I would advise not trying to make a duck of the K2; it isn't an AM rig.
Get yourself one of the Johnson line.  They're great rigs when properly
cared for.

best wishes,

dave belsley, w1euy
