ANT2 port w/o Tuner

[Edward R Cole]

Ross, etal:

This had been discussed when I first got my K3/10 last spring.  I
chose not to get the tuner since I was also not getting the 100w
option and have a 300w ext. tuner.  Subsequently, I bought a 2kW
manual tuner for future use with amps (300w sspa and possibly a HB
8877 later on).

I have 17 antennas at my station so there are certainly more than the
K3 can switch, but I do run separate amps/antennas on HF and 6m and
that entails manually switching cables.  A second antenna port (call
it ANT2) would really be useful for quick switching.  I have a 6-pos
coax switch for selecting my HF antennas.

I kept an e-mail suggestion on how to implement a second ant (can't
put my finger on it right now) with thoughts of building it (and if
there was interest offering it as an aftermarket kit).

But there was some involved circuitry to handle switching so not sure
what it would cost.  If I would guess it would likely be $100-150 so
would anyone chose that over just installing the internal tuner?

I am really overloaded with other projects so this one will not see
daylight for another six months, at least.

What I'd really like to see is a second antenna port that I don't have
to pay $300 for since it's bundled with an antenna tuner I don't
want/need....

Ed,

I did the internal even though I use a remote tuner at the antenna feed for
several antennas as well.  The internal tuner matches the load from the
transceiver as the impedence does change when going through the amp, but the
biggest deal is that I get a low power tune to the remote tuner before I
bring the amp on line.
