RC2 - high side and low side different

Can the RC2 controller be set up so the high side driver configuration
is different than the low side?

Thanks and cheers,
Fred KE7X

Re: RC2 - high side and low side different

Fred;

If you mean the KRC2, the high and low side drivers are locked together in hardware, so no they cannot be separated. With 16 configurable selections, it meets most folks needs.

This is also a good time to remind folks that the final KRC2 configuration tool is on the Elecraft web site. The text may say "beta", but it is the real thing.

Re: RC2 - high side and low side different

Thanks Jack. I figured that was the case. What I want(ed) to do is drive
the 6-pack x-bar switch which has a tribander on it so 10-15-20 will be
mapped to the same output PLUS drive a 6-band bandpass filter which
needs to have separate outputs for 10-15-20. Any ideas?
Cheers,
Fred KE7X

Re: RC2 - high side and low side different

Fred,

You can wire "OR" either the high side or the low side.
If you are running the tribander on the low side, just connect the 10,
15, and 20 outputs together, and drive the bandpass filter from the
separated low side outputs. Swap 'high' and 'low' if required.

Re: RC2 - high side and low side different

Thanks Don. With diodes that will work great.

Re: RC2 - high side and low side different

Fred,

With the KRC2, no diodes are needed, just connect them together.

Re: RC2 - high side and low side different

Thanks Don,
I guess not normally but I need to drive two separate devices -- the ant
switch with the tribander and a 6 band bandpass filter. 10-15-20 can be
wired together to drive the ant switch but need to be separate for the
bandpass filter.
Cheers,
Fred

Re: RC2 - high side and low side different

Fred,

Your first post indicated that you could drive one from the high side
and the other from the low side. If that is the case, then diodes are
not required. If both must be driven from either the High side or the
Low side, then yes, diodes would be required.

Re: RC2 - high side and low side different

No diodes, no extra connections. Just use he KRC2 utility to change the band map so that a single output is dedicated to the tribander, and others to the band pass filter. I do this in my own system - I have one output that selects my A3, leaving other outputs for other purposes. It is very useful to use the XVT outputs for this, or others (say 60m) that might not be used normally in your station.

Download the KRC2 Configuration Utility and play with it. You will get a good idea as to what all you can do, and may discover something really useful!
