I'm considering the acquisition of a KRC2-unit, but I'm not sure it
will
fill my needs in my specific contest configuration.
I want to use the KRC2 with a K2 with a KPA100, a KAT100 and a linear
(SB220) as first radio, another transceiver as second radio, a
PC-contest-program (TR-log or similar), antennas swiching-relais (to
switch
antennas back and forth beetween the two radios) and other switching
devices
for keyer and headphones.
My question : is the KRC2 the unit I need ?
The KRC2 does not currently support two radios connected at the same
time. In other words, if you want to connect a K2 and some other
transceiver to determine which antenna is selected, the KRC2 will not
handle this directly. It _will_ other rigs besides the K2, but only one
at a time.
You could accomplish this with a pair of KRC2s, one controlled by each
radio, using the outputs to control relays for antenna switching. It is
relatively easy to connect the KRC2s and relays so that an antenna
relay will not be energized if both radios select the same band.
I do not know of any automated antenna selector currently available
that handles more than one rig at a time.
Another question : the KRC2 manual mentions a "daisy-chain" to couple
the
KTA100 to the KRC2. What is this ? Another word to say parallel
connecting ?
Your guess is correct. The KRC2 allows you to connect the K2 to one DB9
port, and the KAT100 or other accessory to the second port. If you have
a KAT100, the 'Y' cable that is built with that unit would connect to
this port.
Thank for your help
You are very welcome!
