The KRC2 is usable with the K3, and provides a lot of capability, however, you can also use simpler systems. There's BCD-encoded band data and you can get an antenna relay driver for about $20. that'll work with that- http://www.unifiedmicro.com/decoder.html.
I'm planning to build a little circuit to take those BCD outputs and provide the ICOM band select voltage for my older ICOM amp. I'm starting the testing and calibration phase of the basic K3 assembly now, having started yesterday AM, and taking plenty of time out for other stuff, including nit-picking the manual. 73, doug Date: Wed, 24 Oct 2007 05:29:00 -0600 From: John Reilly <[EMAIL PROTECTED]> Is the functionality of the KRC2 built into the K3, or is it still necessary for interfacing to amplifiers and antennas? - 73.
