[Elecraft] 14.03 MHz Continuous Tone/Carrier?@#$

[David Cutter]

This comes under the category "unintentional radiator" and there are legal 
limits that must be met.  One problem I can see is that the equipment could 
be tested and approved without wiring it into a "system" and it might meet 
the requirements, but when fitted with all the accessories it may not, but 
these may be deemed to be in your domain not the manufacturer's (I'm 
guessing and supposing).

You need to find whether the interference is coming directly from the box 
(unlikely in my view) or is radiated from attached wiring, most likely. 
Snap-on cores on these wires, including the supply wire to the wall wart, 
should cure the problem.  You may need more than one pass through each core; 
up close to the router.
