I think this is likely correct.  I used Astrons in an environment loaded 
with RF (1500 watts into an inverted L a few feet away on 80/160) and 
never had any problem.  However, 20 amps is marginal for a K2/100 and 
the Astrons defnitely do cut out when you exceed their current ratings.

Everything else electrical in my house suffered from the RF, including 
some terminating resistors in my alarm system that appeared to be 
*vaporized!*.  But the Astrons did not hiccup.
