"Remoting" at T1

[Ken Alexander-2]

Folks,

My HF antenna consists of a 28 ft vertical with eight
20-foot elevated radials.  I use an SGC autotuner at
the feedpoint for multiband coverage and I'm very
satisfied with the setup.  Coax from the shack to the
antenna is buried.

When my K2 is completed later this summer I will
complete my conversion to 100% QRP by selling my Yaesu
FT-857 and the SGC tuner, but this wasn't intended to
be a For Sale message.

I'll replace the SGC with an Elecraft T1 (I want to
use it on an FT-817 as well).  I like the idea of
installing the tuner at the antenna feedpoint, hence
my question:  Has anyone "remoted" a T1 before?  I was
thinking of doing this by bringing the Tune switch
contacts to a small jack on the side of the case
(assuming there's room) and plugging in a relay that I
could energize from the shack, i.e., closing the relay
contacts would replace pushing the Tune button.  

I'll see the results on my SWR meter, so the LEDs on
the T1 wouldn't be missed.  The T1 would be installed
in a weatherproof cabinet, which could also house the
relay...and the slick way to do the switching would be
to send 12V down the coax.

I assume that this configuration would work better
than using the T1 in the shack for multiband
operation, but maybe I'm wrong.

Good idea?  Dumb idea?  Has it been done?

Thanks and 73,

Ken Alexander

Most of the SGC tuners will work at 5 watts.  I think the T1 is neat,
but why bother replacing the SGC, waterproofing the T1, etc?  You can
still build a T1 and use it for portable operations!

You're right. On those bands where the SWR and reactance are high,
having the tuner at the antenna base is an advantage.

Hi, Ken!

It's very easy to "remote" a T1.  There already exists a 3.5mm stereo
jack on the side of the T1's case.  Get a 3.5mm Stereo phone plug and
wire the normally open contacts of your relay across the "ring" and
"ground" connection on the jack (no connection to the "tip").  This will
duplicate the functionality of the "PWR/Tune" button on the front of the
T1.
