You make some very good points. Since you sent this to me directly, no one in

I'm sure Elecraft doesn't intend to compete with MFJ, but I don't think they
are in the Alpha league either. The K3 is a good product at a good

FWIW, the 6M-on
I'm not so sure. It's the same size as the K3, which is absolutely tiny.
Including the
built-in power supply, it's relatively light. So for operation in the field,
that is a big
plus. For those who operate 6 meters, that's imperative. For those who want QSK

While "Stupid Yuppies" may be a bit harsh, Jack has an excellent

It is full QSK, but silent, using PIN diodes rather than vacuum relays.

It looks like Elecraft may be abandoning their traditional "most bang
for the buck" market position in favor of selling over priced "matching
accessories" to stupid yuppies.
Unlike the K3, a $2000 500W amp is not going to be in the "best value"
position in anyone's analysis, although I'm sur

The ALS-600 price (about $1250) includes the power supply. BUT - no

Together, this combination just breaks $1500. It works superbly with
the K3. The KPA-500 is expected to be priced around $2200. Worth every
penny I'm sure and I'll be among the first wave to order it. But, it

What I learned at the Elecraft booth
at Boxboro Convention is that there is
no ATU built in to the KPA500. I do not

After 45 years on the air, I'm finally getting an itch to bump my power over
100 watts; 500 - 600 watts seems like a reasonable amount of 75 meter power
for me. I'm seriously looking at amplifiers and tuners, but hesitant to
make a purchase decision before getting at least some warm fuzzies about

The The KPA500 power transformer toroid is rated for operation at 50 Hz

Hi Wayne and thanks for the info re KPA500 power supply
The toroid transformer in the KPA 500 takes up most of the space available
in the K3-sized cabinet and it is amazing that the developers managed to add
a linear regulator and even a 500W amp etc. – hi!
Now toroids are a bit "hard" on the inr
Yes. The KPA500 has an internal 60-V linear DC supply based on a
toroidal transformer.

What are the comparitive amounts of heat produced in a solid-state amplifier

Guess it depends on operations and locations, but I see the KPA-500 meeting
some broad operating needs.
I frequently operate portable, for contests, and enjoy a power boost above
exciter level power.
I've looked at the somewhat portable ACOM 1010, but it lacks 6 meter coverage
