[Elecraft] K3/Icom amp interface

Your question has two answers: 

 For the 2KL a BCD to 1 of 8 decoder can switch the necessary 
 voltage dividers to create the analog (stepped voltage) band 
 data signal needed to switch bands with the 2KL or 4KL.  The 
 W9XT "BCD-10" is capable of providing the necessary "switch 
 to ground" signals to easily drive a set of voltage dividers 
 in this application. 

 However, unlike most of the other Icom accessories, the PW-1 
 will not switch bands based on the analog (stepped voltage) 
 signal and requires specific frequency data from the Icom 
 CI-V "transceive" broadcast. .  

 I know of only three devices in current production that will 
 translate Elecraft (Kenwood) CAT data to the Icom CI-V format. 
 They are: microHAM Station Master (PA control function),  the  
 microHAM microKEYER II (auxiliary CI-V output) and microHAM 
 MK2R or MK2R+ (accessory serial function).  The now discontinued 
 microHAM Band Decoder is also capable of providing the CAT 
 translation if you can find a used one.
