What is the best FM tuner with remote tuning?

Fanfare FT-1A.

Not really the best tuner for DX'ing, but if you're looking
for remote capability then DX'ing is probably not your main
concern.

I have not heard a better tuner on medium/strong signals
than the FT-1A. There are certainly (a few) equals, but none
better.

Gotta disagree Brian, but that's what's great about this
hobby! I agree that both the TU-717 and T-2 (especially the
T-2) trounce the Fanfare in DX'ing. No question. If DX'ing
is of primary importance then I'd say a vintage analog tuner
such as those mentioned by Brian is definitely the way to
go. But when receiving medium/strong signals I don't think
either comes close, let alone in the same league. I have not
heard better bass from FM than with the Fanfare locked onto
a strong signal, except maybe the Day-Sequerra Ref. Even the
MD-108 falls short here (although I like it's top-end a
little more).

I use the tuner section of my old Yamaha CR-2040 for my DX sessions. The sensitivity on that thing is crazy. Not the
best sounding tuner but given the distances of the stations
I usually try to bring in with it that point is moot. I'd
say the TU-717 is a little sweeter sounding than the T-2
but not by much.
