Using SB 200 With KX-3

[Ken Schillinger]

 

Hi,

My name is Ken / ke7hge and I'm new to the group.

I haven't purchased a KX-3..yet. I am on the cusp.

One question I have is regarding the possibility of connecting the KX-3 to a
Heathkit SB 200 I have setting here. I bought the amp, installed the Harbach
(sp?) soft key and soft start mods with the idea of using it with my Yaesu
897d. I have never hooked it up, but then again I have 100 W available with
the 897. I'm considering selling my 897 to partially fund the KX-3, which
would leave me at 10 - 12W which is fine, except.sometimes higher power is
desired. What does everyone think, will the KX-3 and SB 200 be compatible,
and if so; will I be able to drive the SB 200 to a point where I will get
60-70 W output?

 

Thanks for your consideration, Ken / ke7hge

 

 

I lead a well ordered life; random is an order.

Hi Ken:

There is a Heathkit forum you could try this question out on.  From what I
have been reading, 10-12W is a little low on the power curve for the amp
and getting it tuned up would place some stress on it.  When I use it, mine
likes to run at 50-60W input from my K3.  Gives me approx 500-600W out.

I believe there will be a matching amp for the KX3 coming out.  That may be
more in the cards.

Your mileage may vary, however.  As noted by Wunder below, there are folks
out there who are doing it.

Good luck.

You can set your FT-897 to 10W and try it. That is what this person did, and
got 110W out:

It should work fine.  I was able to get about 100W out of a Drake L-75.
  Just tune the plate and load controls for maximum RF output. (There's
not much point in trying to dip the plate current.  Since almost all the
current is resting current, you don't see much of a dip.)

Ken,
 
Try driving your SB-200 with just 10-Watts output from your FT-897D. RF is  
rf, no matter the source
for such purposes! It would help if you had an accurate Wattmeter to see  
the results! I think you'll be
pleasantly surprised.
 
Bert, N4CW

I happen to have a KX3 and a SB-200 (with Taylor 572B's) on my bench.
Without trying to hard, I was able to get ~110W out on 20m.
