HI Ron:
On a quick look, this PS looks attractive, but my concern would be if
it is designed to power electronic devices. Most of the write-ups
deal with people who are powering a 12V DC picnic cooler, where the
purity of the DC power is less of a worry.
I think there are better units
I have had this K3 up on the air for a few days now. I would be curious to
know how I can get more lows or bass out of the TX on SSB with my PR-40.
The audio reports I get from other stations are that I have a lot of highs
and they can't open up their filter to get enough bandwidth on my signal
Try bring the lower four setting up to zero. The way it is now, to me,
seems to not allow much drive of the low end audio frequencies.

Recently, I sent the KPA 500 in for a repair ( probably my fault ) which they
covered under warranty.
When the amp came back I noticed these Mods and upgrades:
Replaced 39PF 1kv 17 meter mod cap with a 2kv. Added fan and side handle
spacers.
Would the spacers help any with fan noise?
By lower four settings you mean the 50hz - 400hz parts?

The rule of thumb in the world of professional audio is that you
should -cut- rather than boost frequencies to achieve the sound you
want when using equalizers. So, if you have a lot of highs... cut
the highs. Adjust overall gain upward to compensate if the overall
level becomes too low.
I've looked at several small 2-5 amp switchers for possible use with my KX3
(whenever it arrives). All have been pretty RF noisy. I haven't looked at
the Fry's or Amazon units, but I'm a little suspicious and I'm getting tired
of spending money!! So far, my Gamma HPS-1a seems to be the way
I haven't got a KX3 yet but when I do I will power it the same way I power my

a very nice size for powering the small equipment like the KX1 or

I don't know where Bob gets those settings. I've got a Gold LIne and

First of all, you probably don't need an external equalizer, because the
K3 has an 8 band equalizer built in. The standard 2.7 kHz filter can be
made to sound acceptably good, but
Hi,
I have a couple K2 items here, but no K2. I wonder what the value of
them might be.
1. K2 100 watt PA..KPA100 assembled...Ready to go.
2. KAT100-1 150 watt Auto tuner Assembled with DB-9 cable set.
I believe that neither of these units have had much if any use..
Thoughts...Interest...
Keep in mind that the PR 40 microphone is very sensitive to 'proximity
effect' (where close-talking the microphone results in a significant
rise in low frequency output). I'd suggest that you keep at least 3 to 4
inches away from the microphone while speaking, and keep that distance
*constant*
I have a KAT100 and KPA100 for sale. Both enclosed in the EC2 enclosure and
in perfect condition. Work without issues with my K2, but I only use the K2
at low power, and do not need the amplifier/tuner. I purchased both from a
ham/builder in December 2011 for $750.00. Will sell shipped/insured
I would start at zero across the board, lowering the low end and
adjusting the mids and highs *slightly* upward until you get a good
balance of decent lows and good presence on the mid to high end. With
a little patience and a good ear, you'll get an excellent sounding
signal out of the K3.

Those are good recommendations, Joe. I agree with working close on

There's a reason those low frequency ranges in the Human voice are called
the drone. They carry virtually no information but are simply a background
sound.
The problem is that the human vocal apparatus cannot modulate such low
frequencies effectively. They work on the higher-frequency harmonics
I could be wrong, but I think that the Dyson bladeless fan has, in its
base, a regular ol' fan, with blades. As I understand it, that fan
blows air out of holes in the trailing edge of the circular airfoil.
Aerodynamic effects cause a larger volume of air to be dragged through
