K3 so2r advice please

Strongly thinking of getting into so2r primarily for cw. With 2 K3's, what external hardware do I need? I realize this info is out there, but I really want some practical real world advice.

Thanks,

Joe

Probably the best is the YCCC SO2R Box. It's a club project, sold as a
kit. Reasonably easy to build, lots of soldering, but no SMT. 5-6 hours
by the time you make the cables. They've done a half dozen group
purchases. About $200, I think. Send email to Dennis, W1UE, if you're
interested.

Joe, this is a tough question to answer. Hardware requirements are
driven by several things.

I was lucky and found a nice used Microham micro keyer 2r+ for less than
half of new. I really like it as it's very powerful (and trust me I am
no expert on the subject, I'm still learning). The SO2R box was the
easy decision.

The biggest challenge for me is antenna switching. I run tribanders for
10,15 and 20 so I needed a good filter/triplexer setup. I ended up
going with a full set of high power 403A filters and the triplexer. I
used the high power filters as I wanted the filters on the amplifier
output. For antenna switching I'm using a hamation 2x8 switch and
integrated controllers.

If your running monoband antennas you could use 200 watt filters between
the K3 and amplifier with out the need for the triplexer.

The alternative is a 4O3A filter just for the tribander to provide a
separate feed for each band and a set of monoband low power filters
(e.g., the 5B4AGN kits) between the exciters and amplifiers.

There are multiple options for SO2R controllers - you need to be able
to switch a single set of headphones, mic, PTT, CW and potentially FSK
between the two rigs. On the "simple end" is the microHAM micro2R,
or TopTen DXDoubler ,the YCCC box is middle of the road, and the
microHAM MK2R+ is the "high end" with built-in sound cards and basic
station automation functions.

You need a pair of bandpass filters, such as Dunestar 600.
You need a means of distributing all antennas among 2 radios, such as the WX0B Six-Pak.
You need two band decoders, such as W9XT, for the BPFs/Six-Pak.
You need an audio box (Dunestar makes one) that can select:
left radio in both ears.
right radios in both ears.
left radio in left ear, right radio in right ear.
You should have a Winkey USB for 2 radio CW and all-mode PTT.
You also need one antenna per band, or two tribanders, or one tribander and a triplexer.
You need two amplifiers.

That's all I have.

Re: K3 so2r advice please

Thanks... I have the antennas to use, I just don't have all the other stuff.. I'm planning for upgrading over the next few months to support SO2R, so this is good info.

Joe,

See photo of KE7X doing SO2R from my station in the photo section of the
Elecraft webpage for his set up.
