Someone had sent me a link and comments on an antenna what had three legs either
side of centernot three wires cut for seperate bands.
I lost the email and since it's been after 1990, the short term memory loss
thing has set in.
Anyone have a link to the information? I recall someone
Thanks to all for the reference to p.25 of the KAT100 manual on this

Chastised myself - chalk it up to reading the pdf file on slow computer :)
and the page scrolling by me in a chunky way I guess.

I have a question about AM receive bandwidth options. I don't see in the
manual a definition of the allowed DSP BW for each mode. I know that the 6
kHz xtal filter is suggested for AM, but wonder if the DSP bandwidth can go
wider, perhaps 10 kHz for BC and solid SWBC reception? If so, can the FM
For tuning amplifiers many of us use a string of high speed dits so the amp
can run at full instantaneous power while keeping average power down. It's
easier on the tubes and you don't need such a stout dummy load. TRLog has a
feature to do this -- no matter what your keying speed is set to, you
Dealing with the last unresolved problem with my K2/100:
When using the K2/KPA100 on CW, regardless of power setting (above 11 watts,
that is), the power output fluctuates above the set power level by about
10%. With the power setting at 90 watts, the output will alternate between

Joel,
I just updated this topic on the FAQ a couple days ago. Please take a look and
let
me know if you have any additional questions. As far as doing a mod on the
filter
slots, I don't think Elecraft at this time would endorse this, but Wayne or
Eric
would have to comment on it.
...Alternately, can a coupling
capacitor be used across the filter slots to just use DSP for AM BC?
No, a roofing filter is required. Please see my remarks the other day
about IF image response.

Is it possible to buy only bare boards from elecraft? I'm thinking
about a KIO2, but i already have all the parts in my junk box, and $90

FM filter in AM. (With relaxed image reject specs.) I do this on all my
other radios. In that case, what is the max DSP b/w?

This is already discussed in the FAQ. AM RX is OK with the FM filter.
You can also copy AM through an SSB filter in SSB mode; the K3 is
extremely frequency stable and opposite-sideband rejection very high.
You can optionally use the RX EQ menu entry to cut the bass frequencies

Hi Matt,
We do not sell raw PCBs without the parts. The price we sell a product
for is not just based on raw component cost. It also includes our
amortized engineering development costs for designing and writing code
for each product, the overhead to purchase the components and carry them
in
too bad the FCC recently allowed the AM digital to run at nightime,
which makes adjacent channel listening rather difficult. With too
wide a receive bandwidth...will not the IBOC digital streams come

If the 'regular' contacts are the same as what was previously
supplied with the various Begali magnetic paddles, they have
problems with many keyers, including the K2's internal keyer,
the Logikey, and others. So the gold contacts are a very good
investment.
The issue with the regular
That is correct, and also the K1EL Winkey keyer. Steve provided
me with a chip fix for the Begali Simplex Mono which had the funny
material for key contacts. Steve did considerable research and
finally declard the Begali contact material was acting more like a
diode, creating a peculiar problem
Or how about just a little do it yourself gold plating of the standard
contacts?
The issue with the regular Begali contacts (as well as those used
by Schurr and others) is that they appear to be of an alloy that
forms a semi-conducting surface.
The solution is to add a schmidt trigger
In the past day or two I have noticed a change on the K3 order page.
The KFL3B-FM was previously listed as a 7-pole filter at $99.00.
It is now listed as an 8-pole filter at $120.00.
Is this an error correction or a change in the specifications? If
this is a change in the specifications,
Hi Joe,
We've decided to go with a 8-Pole FM filter manufactured for us by
Inrad, instead of the lower performance discrete 7 pole xtal filter we
were planning on designing and using. The 8 pole filter has an excellent
shape factor and better ultimate rejection than the 7 pole discrete xtal

I stand corrected! :-) Thanks for the info.
Those that paid the old price of $99.00 for the 7 pole FM filter will
still get the 8 pole FM filter for that price. (not $79) New orders will
be at $120.

Does anyone here operate Pactor I via soundcard? If so, what

Respond directly or via this list. The more info the better!

Personally, I cant hear anything above about 4000 Hz, that
would be 8Kc bandwidth on AM.
The R390a had 4Kc (slightly too narrow) to 8Kc then 16Kc.
4, 6 and 8 Kc are the most useful for me, as that gives 2, 3, and 4Kc
audio output if tuned dead on carrier.

Like many others I was expecting the first ordered
batch of K3s to be delivered in equal sized groups,
over the 5 weeks or so that the guys predicted K3
deliveries.
Rather, we've seen very few deliveries up front with a
close watch for feedback, allowing for revisions in
the process that is
Sorry, my main point was to say that I managed to get

You might want to try some Caig DeoxIT Gold on the contacts if they're clean.

Hi Guys,
I put up Bobtail Curtain antenna for 20 meters for the CQ DX contest
this afternoon. It is fed at the center vertical element. Here is the
problem. It requires a matching network (tank circuit) at the feed
point. So I took my MFJ-269 antenna analyzer out to the feedpoint and
tuned

Sounds like a judgment, but it's probably just a nudge. You're right.
I should'a stayed up the night it arrived and finished the assembly,
but my job won't allow that. At least with my boss out of the country
