[Amps] KPA1500 Efficiency vs. RF-Kit B26

[Bill Steffey NY9H]

it's not just the two quiet fans on the HUGH heat sink assembly,,,, 
truly a unique design ....

724 DAYS    QUITE COOL  very quiet receiver... & love the third preamp 
on 6 ...&   many step attenuation...

you can VNC the entire set of screens from a computer  or tablet.... via 
wifi, Ethernet //// VERY REMOTABLE

TO SAY THE AMP IS QUIET IS A LARGE UNDERSTATEMENT...      unlike any of 
the jet engine equipped LDMOS amps.

As far as a comparison, I was just looking for the beginning of the 
thread,,, with the B26 RF kit in the subject line, and any info provided.
