Tom, The KRC2 is just great - lots of function and opportunities for you to be creative with your antenna switching.
I worked out a plan for automatically switching my antennas with it - and I am switching a lot of antennas in 3 selection banks (some even appear in more than one bank). The KRC2 drives my own diode matrix which takes advantage of the 'wire-or' capability of both the negative and the positive outputs. When I have everything completed, the antenna selection will follow the K2 band and I will be able to switch from one bank of antennas (horizontal polorization, vertical polarization, or beam/broadband set by tapping the Fx buttons on the KRC2. Yes, in addition to the KRC2, I need 12 remote relays in the antenna field and 3 relays in the shack, and these relays are controlled by 'logic' provided by using the KRC2 positive and negative outputs together along with the 'wire-or' function afforded by simply tying to outputs together - the use of a positive output along with a negative output on a relay coil provides a logical 'and' function available for use. Jack Brindle has been generous to offer a special configuration program for me because the configurator program is not yet available. I believe Jack has one working for the Mac, but Jack does not 'do Windows' (I hope I am not 'telling stories out of school') - in the meantime he seems to be willing to provide special releases of the KRC2 firmware for those who need it. I am using mine in K2 mode only since I have no Kenwood gear. The computer serial port connects directly to the KRC2 and software control of the K2 is available through that connection (no need for an extra K2 to computer cable). The KRC2 and K2 works with all the K2 control programs that I have tried. No problems with HRD and several others but I have encountered difficulty with the N4PY program only when used with the KRC2ACC version, the standard KRC2 handles N4PY control nicely. 73, Don W3FPR > -----Original Message----- > > I don't think I've seen any comments regarding the KRC2. > > Ever since my K2/100 booted my Orion out of the shack I have been > using my Array Solutions "Rat Pak" auto-antenna-switch in manual mode. > > The KRC2 would put me back in auto-antenna mode again. > > If I connect the KRC2 to my K2 I assume I can control the K2 from > PC software transparantly from any software package that controls > the K2 now.
