COMMON MODE RF can cause loss of regulation (low voltage, high voltage,
supply shutdowns) of Switch-Mode power supplies,
Such as the SMPS models you have listed, that you are using.
1. TEST with a 50 ohm resistive dummy load
2. Correct your Antenna System. You mistakenly believe

Can anyone tell me what this
I decided to take my K3 up to the 40 meter phone bands this evening.
The first contact for the K3 was with the Peter Spaeth, KX2X (Uganda) running
his Elecraft K2 (I assume, unless he also has a K3 by now).
Not bad for the first K3 phone contact !

David,
Thank you for that correction.
In addition, I left out these 2 paragraphs,
the second is critical for proper WCC103 sensor replacement.
The Weller WCC103 temperature sensor is actually an iron-constantan
thermocouple
(possibly a Type J). Weller used Type K thermocouples for its EC

For a variable temperature soldering station -- and using 60/40 (Sn/Pb)
solder -- stay within the range of 650 to 750 degrees F (345 - 400 degrees
C).
Personally, I always set one to 700 F degrees (370 C) --- since I learned my
techniques in 1970s with the Weller TCP series with 700
Get your wish list in to Santa (Wayne and Elecraft staff) early this year !
Sounds like you will have something under the tree !
