Wow that was a close one. I was planning to buy a loaded K3 + P3 as a back-up

There appears to be more demand for this than we thought, so we're
looking into it again.

I have not detected birdies in the K3, but have not used it a 28-MHz
so far. Until I have a VHF transverter I will not be able to examine
this very well, but I will be using 28-MHz as an IF for both 144 and 1296 MHz.
But is the stiffener standard on radios after spring-2010? My K3 is

Dear Elecrafters,
How to decode almost correctly the NCDXF/IARU beacons with a different pitch
than 700~800Hz
I'm using a pitch of 450Hz in order to use less bandwidth and it is more softer
to my ears, especially on long runs.
I can hear clearly the beacons with the 450Hz but even I'm shifting
I have a pair of Radio Shack Minimus-7 speakers which I've had for 20
or 30 years. They have wonderful fidelity for speakers of that size.
For a long time I used a 30 watt stereo amp to drive them. What the
Minimus-7 does NOT have is any degree of efficiency. They are, in a
word, spectacularly
I think the problem is, as you say, the decoder isn't sensitive on weak
signals. But what's the point, anyway? There are a number of programs which
will tell you what beacon you will hear at any given time, so you don't need
to decode it, just know that you heard something.

I've been told that it is good practice to clean a completed PC board
with either acetone or denatured alcohol and a small toothbrush.
I could not bring myself to do this when I completed my KX1 - it just
seemed (at least to me) somewhat risky to be brushing a liquid with a
nylon toothbrush
Being curious I checked my K3 (4043) which I run with an external
speaker (an old National 1950's era 10-inch speaker -probably 4 or
8-ohm). Comfortable audio with volume set at 9-oclock. Turning on
NB does not affect the level. NR lowers volume which requires
adjusting volume to 11-oclock
When I was working for HP/Agilent, the rule was that you NEVER clean a
board that way because of the risk of ionic contamination.
The rosin flux used in multi-core solder is normally the mildly
activated (RMA) type. That means it includes a moderate amount of the
acid that is used to remove the
The noise signatures in Bill's link are very characteristic of switch-mode
noise. For example, take a look at the 80m NW sweep. Classic switch-mode
noise where 'bumps are seen at precise intervals of the power supply's
switching frequency. At roughly -110 dBm, my guess is the source is not

Stan,
Do NOT attempt to remove the flux - it is not conductive and will cause
no problems, even though it may look slightly messy.
In fact, attempts at removing flux can result in unanticipated
problems. If the flux residue plus solvent gets under connector headers

Take a look at Faros by VE3NEA: http://www.dxatlas.com/Faros/

Too much solder, usually using solder too big in diameter, is one of the
fastest ways to end up with excess flux all over the place.
For PC board work I rarely use anything larger than 21 gauge (0.032) and
often solder half that size (0.015).

Yes, there is an adjustment - there is a felt washer behind the knob,
