Got around to replacing the 4 5711 diodes today and problems are gone! Also
chunked a bnc cable that the shield came off the plug.
Thanks everyone.

My MFJ 4245 switcher doesn’t seem to be as strong. Its adjustable from 9-15V
Has a detent for 13.8V Except now in the detent its only 13.2V and that’s with
no load everything unplugged measured with my fluke 187 meter with fresh
batteries. Is it just my old senile mind or is something
Zack,
I think I understand what you want. Let see if this states it:
1) Flex-5000
a) output 160m-10m
b) output 6m
2) KPA-500
3) Two antenna:
a) Stepr 80m - 10m
b) Stacked 6m loops
You would like a switching system to allow either output of the
Flex-5000 to select the KPA-500, while the
I copied the wrong part number on the Surplus sales site:
s/b (KC) 12W1008 as the least expensive cross-over relay rated for 1kW
the CX800M has UHF connectors and works on 12vdc, whereas the relay
above is N-connectors and requires 28vdc.

1/ Tuner can select only for the output port in use, this leaves 'the
other choice' available for other radios. If the tuner is currently on
antenna port 2 then it does not drive the outputs associated with
antenna port1
2/ Tuner can remember previous tunings per selected antenna driver

I disagree. I have switched to full-time use of 200hz 5-pole filters in
both receivers for cw, configured as 300hz
Unfortunately, this scenerio is exactly what I expect many with
KAT-500's to actually try and tune. Unless there is some logic built in
to the tuner to inhibit operation for these crazy conditions, the future
is going to be full of toasted toroids.
The scenerio goes as follows. The tuner
Chuck,
I'm certainly no expert. But, I was facing the same delema, which
filters to buy. I have my main rec filled with 6, 2.8, 1.8,400 and 200
filters. When I recently added the sub-rec, I only bought the 2.8 and
200. So far, I've been pleased.
Good luck, you'll get a lot of comments on
I do not have need of a tuner for any antennas so I am looking at this from
a K3/K3/KPA500 configuration
The Magic Box to control:
- Minimum of 4 antennas per bank. Additional banks can be added so if you
have an antenna per band for bands such as 160-6M or more you can
accommodate them.
- There
Does anyone have any experience with Elecraft's KRC2 band decoder/switcher
and the Dunestar Model 600 multi-band bandpass filter? I'm contemplating
this combination for use with my K3 and would love the opinions of anyone
who has used this combination. I want to make sure I get automatic band

This seems awfully expensive.
Array Solutions doesn't spend that much for the relays inside their Six Pak.
Top Ten devices doesn't spend that much for the SPDT relay inside their A/B
station selector. That unit goes for $77, and that includes a nice box and
the connectors.
The T/R switch
Another option is a fun kit to build designed by KK1L. It is a 2x6 antenna
switch and SO2R band decoder board. The external switch has two inputs.
This will allow you to put the amp inline with ANT1 and ANT2 straight to the
second input. You can than select up to 6 antennas for either output.

Here's a very interesting reference for relays used in just this
application, along with part number and a picture:
This seems awfully expensive.
It is - but the Totsu DPDT coaxial or other transfer relays are
an off the shelf solution. The Totsu solution can be simplified
to two relays by careful choice if cable lengths and adding a
couple compensating stubs in the amplifier leg.
One can certainly spend
I removed the 500hz filter pair that I used to also have installed.
1.8 KHz and 200 Hz may be fine if you don't do any RTTY. However, for
either RTTY DX or contesting, you will want 500 Hz, 400 Hz or 250
Hz (370 Hz) filters.
