The Mighty KX3+KXPA100 Into a Hi-Power Linear

Tell me I’m not thee only wacko doing this: a KX3 into a KXPA100 into a high power linear. In my case, Ameritron ALS-600S. Took a lot of balancing and RF/SWR hygiene work. But it has settled into a wonderful balance. Got my little rig for my back pack when I want, and the hi-power home rig when I want. Nice. Anyone else doing this?

Haven't gotten there yet, but I would love a BuddiPole. But heck, I think people have just thrown long wires up over a big tree and done well with a tuner. Infinite possibilities.

Re: The Mighty KX3+KXPA100 Into a Hi-Power Linear

In reply to this post by David Ahrendts

I have run KX3-KXPA100-KPA500-KAT500 and it was seamless QSK on CW. A beautiful thing to behold--until I saw what looked like a tear forming on the lower right side of the K3 display.

Re: The Mighty KX3+KXPA100 Into a Hi-Power Linear

I realize this approaches blasphemy, but just a quick note to say I'm
getting a tad under 500 watts (steady whistle) out of an Icom PW-1 when
driving it with my KX3 set for 12 watts out. At this drive level, I didn't
bother to connect the ALC but the amp still has it's SWR etc. safety
features enabled. It didn't like it when I had my 40M dipole selected and
tried transmitting on 14 MHz.!

The PW-1's are going for around $3k and DO have a decent antenna matcher
inside. Admittedly, this makes for a much larger station package, but if
you get a good deal on one, it might be an alternative. Especially if you
also own a K3.

That said, remember, if you're 20 over S-9 at a kilowatt, you'll still be
S-5 at 100 milliwatts.

73, Charlie k3ICH
