Unfortunately the schematic doesn't seem to show up (on my browser), but I've seen the schematic before. It's the BCD to voltage divider network (with trimmer pots) that Joe mentions below. The schematic was once at http://www.qth.com/topten/icomencd.gif but the file doesn't seem to be there now. I'll forward this to Dave Hawes of Top Ten Devices; maybe he can get the image file restored. 73 de Dick, K6KR -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joe Subich, W4TV Sent: Monday, June 02, 2008 9:30 AM To: 'Bob Serwy'; [email protected] Subject: RE: [Elecraft] K3 and Icom PW-1 Bob, There are two approaches that will work to do automatic band switching with the K3 and PW-1. The first is to use something like the microHAM Band Decoder (or new Station Master which replaces Band Decoder) to convert the Elecraft (Kenwood) "IF;" CAT data to Icom CI-V Transceive broadcasts. The second would be to build a BCD to 1 of 10 decoder and use that to drive a voltage divider to create the Icom compatible "Band Select" voltage. The Station Master will be available off the shelf after Friedrichshafen. I can supply notes on the BCD decoder approach but have not built/tested any devices. That is a "low tech" solution and not something microHAM is likely to produce and I'm not inclined to get involved in building "one off" units since that is a relatively high cost/low return proposition. 73, ...
