have been about people using it for more than that ... like camping and
restrictive locations. I'm just saying those folks could get more out

I wish Elecraft the best of luck with the K4, and I am sure they will
sell a lot of them. I am keeping my loaded and upgraded K3, serial
number 0007. I am sure the K4HD would provide slightly better
performance and probably an improvement in usability, but my K3 is
already more than good
Dear Charlie,
be noted that even if the radio shows K3S on the front panel it does not
have to be the K3S inside.
There is possible to buy K3S "facelift" kit on eBay which allows to your K3
looks like K3S...:)
(...they say "K3S esthetic upgrade kit")
Also note that K3 serial numbers ended in the 9### range. K3S serial numbers
began with 10,000.

FWIW .. this question is for Wayne or Eric, could the K60XV be
redesigned using currently available components, or perhaps something
that would allow easy use of the transverters?

I typically run my KPA500 fan on #1 when operating FT-8. It will ramp
up to #3 when the temp reaches 60°C and during extended exchanges, but
quickly ramps back down to #2. I don't find this at all
objectionable. I've never seen the TEMP above 60°C or so. And at

Don't sell the K3 short. The basic K3 is still one of the finest radios
ever made and the difference between it and newer radios is hardly

Go out and operate, experiment with antennas, including the AX1, and see what
has been discussed in this thread is best for you
The point you're missing is that the AX1 wants (needs) a wire
counterpoise to work very well at all, and since it's that counterpoise
wire that is doing most of the actual radiating you're better off trying
to optimize what you do with it. I don't see how that is so difficult
to understand,

It is easy to cancel the radiation from the 'counterpoise' - use 2 equal
length wires running in opposite directions from the base. The
horizontal radiation from each will cancel, and all you have left is the

It is interesting that the seller of the K3 from that estate does

It seems like the K3S has been grouped together with the K3. The K4
will be a different animal. Like K3ICH, I have three K3S's and with
any software I have to select K3 as the rig. The K3 has been out of
production for years. I have seen a number of K3 ads listing the radio
as K3S, here is
Yes, of course. I know how things work. And I agree with Don’s comment that
came in in another email while I was typing. That does NOT mean the vertical
element is the “counterpoise" to a long elevated wire (or more than one) a few
feet off the ground. Yes those wires may radiate, but
What makes you think the wire isn't doing the bulk of the radiating just
because it drags across the ground? Actual RF ground is usually some
distance below the surface, sometimes several feet.
There is a way to prove me wrong on all of this. Connect two AX1's to a
Tee connector coming
Dave's observation is about how the antenna actually works, as
determined by Mother Nature, and, depending how the antenna is rigged,
he's probably right. Antennas work by carrying RF current, any end fed
radiator needs a counterpoise, which, because it's carrying the same RF
current as the
An upgraded K3 (synth, other) is far better than a mere 90% of an S. Where’s

As K9YC said in his reply to you, equal currents go in both directions

simply physics, and it's true unless currents on the

It is always important with an Elecraft radio to pay attention to the
details - Serial number,options installed (including filters), and
upgrades installed are always the minimum essentials.

Of all things this weekend I picked up a late model K3/10 (7928) bare bones

You can reach the trimmer with the band board and tuner in place. Just
put the OFS jumper in place and follow the instructions in your original
manual. The newer K1s have a switch on the bottom instead of the OFS pads.

Not trying to start a disagreement here, but I don’t see the point.
If you want to run a wire antenna, then, good gracious, run a wire antenna.
They work pretty well portable. I carry two in my bag. But I fail to see the
rationale of using the AX1 as a “counterpoise”.
For quick low profile
I ran some comparison tests on 20M with the AX1 against my Buddi Stick
vertical when I first got it. I found the best performance was with the
AX1 on a table top tripod on a picnic table with 2 resonant radials. The
AX1 was about 1 S-unit down compared to the bigger antenna over a 22

The high-value, low-temperature-coefficient trimmer capacitors leveraged in the
design are no longer available. Unfortunately we don't have staff available to
redesign the board to do it in another way, and demand is low.
The transverter interface by itself could live on a smaller board.
Concerning the output variation, I’ve noticed that when I change bands while
the amplifier is hot, the output on the new band starts out high, then
gradually drops. This would seem to indicate that the LPF is heating, and that
the loss in the filter is several hundred Watts. That’s no big deal
I think you'll find that for a short vertical radiator and a single
counterpoise wire the maximum radiation is in the direction of the wire. EZNEC
confirms this and I've tested it with a friend the length of California on 40 m
where with the counterpoise pointed away from him I could barely
