[Elecraft] Questions on the KRC2

[Bruce Thompson]

I've got some questions about the KRC2 box.  I plan on using it in my
vehicle to automatically select the proper filter setting on my SGC500
amp but there could be a bunch of other things that could be fun...

1.  Does it have a power switch?  Running power in my vehicle is always
a pain.

2.  How much current does it draw?  Is it something that could just be
left on all the time?  Does it have a sleep mode?

3.  Can it detect when the K2 is turned off or on and then do something
such as switch on one of the transistors?  (I'm assuming here that the
unit wouldn't actually detect the loss of power but the loss of
communication with the K2).

4.  Can the PC serial port also be an output?  I wouldn't mind
programming it to control other serial devices.

5.  It looks like there is an LED on the front.  Can it be programmed?

6.  Can the unit write something to the display of the K2?  (Useful on a
button press or some automatic function)

7.  Can it detect when the "tune" button has been pressed?  I'd like to
use that to turn off the amp automatically.

8.  How many outputs are available?  Can't quite read the PC board in
the photograph.  

9.  Are there any inputs?  Can the controller read the state of any
lines?

10.  It looks like the wires are passed through the square hole next to
the serial ports.  Is there any strain relief/shield ground on it?

11.  Can the unit be programmed to send things to the K2 to turn on the
sidetone?  This is really useful in a mobile environment if the system
could send CW messages out the speaker as to what it was going.

12.  What is the interior slider switch for?  I assume to put the
processor in program mode?

13.  How "programmable" is the processor?  (e.g. what language, what
development tools, remotely programmable, how much memory is available,
etc.)

14.  Will the buttons on the unit be able to detect tap as well as hold?

15.  Could the switches be remotely mounted so the box could be located
away from the operating position?  Important when running mobile.

16.  How much of the internal state of the K2 can it detect?  Such as
the real time clock?

To see what I'm talking about as far as my mobile setup, check out:

Most of the links are bogus but check out the photos to see what I'm
using.

Thanks in advance.
