K3 add on kit idea

Recently there was a request for ideas for kits that could be useful to
accompany a K3.

When we use diversity mode antenna switching becomes a different problem
than I have run into before. The usual antenna switch routes many antennas
to one radio port. Some of us have many antennas that need routing to two or
more radio ports.

So I could imagine a useful kit would read K3 band decode and map something
like 6 or 8 antennas to 2 or 3 ports and makes sure the K3 does not transmit
into the other radio ports.

Some attention to stations using two K3's or a second receiver might be
useful also. Not sure what this would entail because I don't operate that
way.

Re: K3 add on kit idea

Partial answer to your desire is the Z1300 antenna multicoupler. One
input, and either 4 or 8 outputs. Isolation between each output port and
frequency range of 20 KHz to 50 MHz with very good IP2 and IP3 performance.

It's still under development, but I'm on the second round of prototype
PCBs, with a target ship date around the end of May.

I'll have more details and photos and performance measurements and
pricing at my web page when the ship date is a bit closer. Available as
a kit or wired/tested, and with some options, although the early release
may not have all optional boards available.

Array solutions has such a product called Six Pack. You will like the product, I think, but you may choke at the price.

Re: K3 add on kit idea

The Array Solutions SixPak is an antenna switch, but I don't think it
decodes band line input, at least the one I have doesn't. I was thinking of
their DBS-1 and DBS-2 or "BandMaster" products.

Re: K3 add on kit idea

Actually the KRC2 should be able to do this now. It has up to 16
outputs that can be mapped to switch antennas whichever way you would
like, based on the band your K2 or K3 is tuned to.

You _do_ bring up some rather interesting ideas...

Re: K3 add on kit idea

In reply to this post by Dick Dievendorff

I think you are correct, it is an antenna switch that allows multiple antennas and multiple connections. Such a product that decodes what antenna you want and what connection you want would be a really ambitious product. The SteppIR antennas with a transceiver interface might be a solution. I have the SteppIR and the K3, but my antenna selection is all manual. I don't even have the Six Pack.

Re: K3 add on kit idea

Bill,
We have one of these at P40L-P49Y in Aruba. It works great for switching
beverage receive antennas between two radios. But it's not intended for
transmitting, so it may not fill the bill. For transmitting, we use band
decoders feeding a SixPak (and, as noted, the Yaesu decoder works fine with
the K3).

I believe Mike's original question (not morphed) had to do with
switching RX antennas for *diversity receive*...not for transmitting.
See below:

#########################################################

You can connect up to 8 RX antennas to the RAS 8X2, and then feed the
two outputs to RX ANT (Main) and AUX RF (Sub). You can then choose
any combination (even including the TX antenna on ANT1 if you tapped
RX ANT off on Main) without running the risk of RF being accidentally
sent into the K3 during TX. This would only work for one TX antenna
at a time however unless you added additional switching. Of course
this also assumes you have some reasonable level of isolation between
your external TX antenna and all the RX antennas. If you didn't have
that, the RX antennas probably wouldn't work right in the first place
due to interaction effects.

I am not sure the Six Pack will do the job. From a review of the Six Pack I
found this little piece of information:

"There is one scenario that the user must always be aware of. For example,
if Radio A is on the 20-meter position and Radio B is also switched to 20
meters, Radio B is interlocked out and therefore is disconnected from any
antenna."

I am not really sure that I read this as a limitation for a single K3 or
not. The price is too high anyway.

What would also be nice is to have an option to map memories 0-9 to the KIO Band Outputs.

This would allow for instance, selecting remote antenna matching networks within "the same band." Seventy-five and 80-meters leaps to mind. Switching directional antennas might be another possibility.

Re: K3 add on kit idea

In reply to this post by Mike Scott-7

Like the antenna's...my idea has to do with a lot of paddles / keys. I like a box with 6 or so inputs (stereo plugs), in which i can plug either straight keys or paddles. It has to accept all wiring possibilities. By pressing the straight key down, or paddling first dot and than dash, the input has to recognize the proper wiring. Output has to go to two or more different transmitters. I would love such an add on!!
Tried to program it in a PIC once but as i am no programmer did not succeed fully. A small display can be added to the device. What an innovation for CW, never saw such a device!

This is not a limitation of the six-pak - it is a design feature. The
issue is - the six-pak is designed for SO2R (single operator, 2 radio)
use, and is designed that way so you cannot connect two radios to the
same antenna at the same time. Bad things can happen if you do that.

As noted, there are different solutions for use with receive-only
antenna solutions.

Do you mean something like this

Bill,
This is close but for selection of receive antennas only. All of my current
