[Elecraft] Design flaw in K3s

[James Michener]

It isn't a matter of if your K3s will fail, it is a question of when.   
The radio's current sense resistor (SMD 1206) is rated at 1/2 watt,  
while (depending on options) will dissipate nearly 2 watts at 10 watt 
transmit.  It took several years but my resistor drifted from 0.05 ohms 
up to 0.068 ohms triggering HI CUR errors whenever I turned on the sub 
receiver.  I am glad it didn't unsolder itself.   I did this write up on 
the web.

Note:  The original K3 has a higher wattage current sense resistor and 
should be fine.... they cheapen the K3s
