Solid state QSK amp to pair with K3

[Allan Taylor]

Reflector folks.

I am currently using a Tentec Hercules II amp with my K3. I would like
to check out options for a solid state amp of
1000W or more and QSK capable. I have a Quadra but it pairs nicely
with the MP and I wish to keep it separate from
the K3 setup.

I have seen a nice amp by an Italian mfgr capable of 900W, QSK, and an
internal tuner. Are there any other options?
My realistic budget for now is about 3K. (I may need to wait until the
used market comes along)

Alan, my vote would be for one of the Tokyo High Power
amps.  I have one here and it interfaces nicely with my K3.

Array Solutions is a dealer...

The present choices are:

  1) Tokyo High Power:  HL-1.5Kfx (1KW 160-6M)
     HL-2.5Kfx (1500 W 160-10M) - available from HRO
  2) Yaesu Quadra - any Yaesu dealer
  3) Icom PW-1 - any Icom dealer
  4) SPE Expert - from SteppIR
  5) Ameritron - ALS-600 (600 W, 160-10M)
     ALS-1300 (1KW, 160-10M)

The alternative is to build a BCD to 1 of 10 decoder
(W9XT BCD-10) with drivers or reed relays to provide
the band switching control for your Hercules II (or
buy a commercial band decoder).

73,

   ... Joe, W4TV

Burghardt is getting out of the retail business. They have some PW1
units in their remaining stock for sale at under $3K.

I've used a PW1 with my K3 (and K2) with good success. You'll want to
use a band decoder with it to get automatic band switching, and should
modify the K3 ALC circuit to accept negative-going ALC (to set a
protective drive limit, not as a power control signal).

Another nice amplifier is the SG-500 SmartPowerCube, which puts out
500-600 watts on HF (no 6m). It uses positive-going ALC and protects
itself well from those who would do it harm.
