As hinted to in Don's comments there is another reason for going with the KPA-100.
I love the fact that the KPA-100 has an integrated solid state T/R switch so you can run full QSK. Most of the imported amps are relay driven via the PTT line or RF sensing with a time delay and are not able to be keyed at normal keying speeds. Of course you could always buy an old B&W or Johnson tube T/R switch but now your running 3 boxes with cables etc. The KPA-100 is the "neatest" solution. - Tom K2TA K2 #1117 ----- Original Message ----- From: "Don Wilhelm" <[EMAIL PROTECTED]> To: "Fred (FL)" <[EMAIL PROTECTED]>; <elecraft@mailman.qth.net> Sent: Thursday, December 07, 2006 8:37 PM Subject: RE: [Elecraft] Barebone K2 Amplifier? > Fred, > > Elecraft has the KPA100 which offers automatic bandswitching and a lot of > other features.
