[Elecraft] K3 and Icom PW-1

[Dick Dievendorff]

See also Top Ten Devices application note #3,
http://www.qth.com/topten/apnote3.htm

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.

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.
