[Elecraft] K2/100 question

Mon Feb 25 22:13:00 2002

I would venture to say that the decision to have the threshold at 11w was
based on not running the K2 QRP finals at full-tilt for 15w when the PA
can "loaf" while producing that output.

It's the same reason I drive my amp with 5w to run 100w RTTY instead of
operating the TS-2000 full-tilt 100w barefoot in 100% duty cycle.  It
allows BOTH the TS-2000 and the AL-811H to "loaf" along not doing any
damage to either in a duty cycle that is generally quite harsh to rigs.

PS: K2 #2490 will be on the air soon!  I finally got a soldering station,
panavise and an oscilloscope. (OK.  I didn't need the scope but a 30Mhz
dual channel, dual trace scope for $299.00 brand new was hard to pass up!)

Here's where to get yours! http://www.web-tronics.com/30mhzosos289.html
(Oh, they're also giving away DMM's with most orders!)
