[Elecraft] K3 with a PW-1

[Joe Subich, W4TV]

The PW-1 will bandswitch based on CI-V data or a variable 
DC voltage.  The microHAM Band Decoder (if you can find 
one) and microHAM Station Master can provide the K3 CAT 
to Icom CI-V conversion.  microHAM microKEYER II also has 
an auxiliary CI-V output that will provide current frequency 
data to bandswitch a PW-1. 

If you so not want to do the CAT conversions, it is necessary 
to build a BCD to variable voltage decoder.  I have done as 
design that will provide either variable voltage for the 
Icom 2KL/4KL/PW1 or one of six output for the TenTec Hercules 
or Ameritron ALS-600 but it is not available in commercial 
form.  QST determined that an article on the interface 
"would not be of sufficiently general interest" and I have 
not had time to arrange to have the project turned into a 
kit.   Send me a direct e-mail and I'll send a copy of the 
schematic.
