Jeff, try a Drake MN-2700, you can find them in the used market. It is a
very solid tuner. Good luck.

> My tuner is the venerable Dentron DTR-3KA. I've had it a long time, and
> it is built stronger than almost anything. It can take lots of power,
> and is accurately resettable. It is simply a great classic tuner.
> Unfortunately, even though it was rated for 160-10, I know from past
> experience that it didn't do 160 too well, since if you ran power
> through it on 160 it would arc at abt 400-500 watts!
>
> Naturally, the arc would shut down my Alpha 87A. In the past, I would
> simply reset the amp and try not to repeat my actions. It's been two
> years since I've done that!
>
> Today I completed the installation of a 160 Carolina Windom, an antenna
> which is NOT resonant on any band, but which is supposed to play well
> through a tuner. Without getting into the attributes and liabilities of
> the antenna, I need to resolve a problem.
>
> I was setting the tuner up for 80, and had no problem, either with
> exciter or amp. When I got to 160, I set the tuner with the exciter and
> all was fine. Then I started to give the amp some juice, no reflected
> power - and I forgot that this would happen - when I got to 400-500
> watts, POP! Not only did the tuner arc inside, but it blew my 1000MP
> back to 40-meters (it's ok, just scared me) and the amp went into a
> fault mode and won't come out. I am now sure I blew at least a PIN
> diode. I am waiting for "the guy" from Alpha to call me tomorrow, and
> we'll see. So for now, I am in deep doo-doo. I'll live. Contest season
> (for me) is six weeks off, so my timing could have been worse.
>
> Here's my question: I certainly don't want to tune up the antenna again
> with the Dentron on 160 when my amp is working once again. I am ready to
> get a different tuner, one which can handle 160 MUCH better than my
> Dentron, and would appreciate any advice, from your experience or
> otherwise about the other qualified tuners out there. If you know of a
> better tuner better suited for 160, please let me know. It can be
> something curently in production or an oldie, doesn't matter.
>
> Thanks very much in advance.
