[Elecraft] QSK Relay Box

[John Huffman]

I have just finished building the QSK box designed by Phil Silas AD5X.  It 
really works great!  I use my K2/100 and ASL-600 combination for smooth 
break-in.  Nice to have quiet relays and to be able to hear what's happening on 
frequency while I'm sending.  This will be super for chasing DX.

Phil's plans are at

I use Tom N0SS's T-R relay in the K2 as it is plenty hardy enough to switch the 
QSK box relay and I have the KPA/100 in an EC2 under the desk

This is a great alternative to the Ameritron QSK-5 box as it costs only about 
$100 to build if you buy new parts, and it isn't sensitive to static buildup 
like pin diodes.

Highly recommended.
