[TenTec] Jupiter/LDG AT-11MP Tuner

[Alderman, Chester]

WOW...return it!!

If the tech gave you than advice, in my opinion, you certainly do not want
to deal with them or their equipment. You SHOULD be able to adjust a tuner
at ANY power, up to its rated max. When a vendor starts blaming another
vendor for compatibility problems, they, in most cases, are not someone I
would want to deal with.

Just my personal opinion.

Subject: [TenTec] Jupiter/LDG AT-11MP Tuner

I bought the subject tuner Saturday for use with my Jupiter.

It has been acting a bit "squirrely" I guess. It tunes for a good SWR on 
low power  but that SWR seems to increase as output is increased.  In most 
cases I can touch up the SWR (under higher power) using one or both of the 
Cap and Ind. Up/ Down switches. These increase or decrease those two 
elements in incremental amounts (fine tuning  I guess you would call it.)

I called LDG today and was left with two thoughts:

1.  I should not try to reduce the SWR at power levels any greater then 25 
watts or so.

2.  He mentioned that there has been some reported "problems" 
(un-specified) with the tuner working properly with Ten-Tec rigs. Part of 
it apparently related to the fact that the TT rigs do not "fold -back"  at 
higher SWRs.

I am sort of inclined to return this tuner, but thought I would ask here 
and see if there is any "real world" knowledge on the compatibility (or 
lack thereof)  between these two pieces of equipment.  I know Ten-Tec was 
marketed a internal version of the AT-11 in kit form for use in the 
Jupiter. I guess that made me assume that the external version would also 
insure a large degree of compatibility.

Any comments would be appreciated..  I subscribe to the digest so, if you 
have timely comments that you think are significant in helping me decide 
what to do.. please email me direct.

Thanks..

Bill, W6WLB
