Just yesterday, Rob Sherwood gave a Zoom presentation to the local
SLAARC titled "Transmitter Spectral Purity." He spoke at length about
the evils of fast rise times and cited the optimal rise time as between
6 and 8 ms.

That's I do, sort of -- I use my #1 K3's 12V accessory output to drive a

The K3s are fed with short, fat

I’ve always found and was taught that one should not just dump the power on

Beginning with the earliest K3s, all Elecraft rigs use carefully shaped
keying to minimize clicks while maximizing readability. Wayne
Hello,
This subject came up in a recent conversation, and I had to admit that I do
not know the cw rise time of my K3. It's s/n 444, and does not have the cw
rise time mod that elecraft sells. The firmware is the current version.
I read somewhere that the rise time was decreased in a previous
I do not. The repair invoice from Elecraft only indicated a faulty I/O board
which was replaced.

Hi,
We have openings for two different technical positions at Elecraft!
1. Technician position for our product test group.
- This position requires good analog and digital skills with debug and repair
capability to the component level. Involves use of Spectrum Analyzers,
Oscilloscopes
Do you know just what failed on the I/O board? Was it possibly due
to static discharge?
I tend to leave an antenna connected, except during active weather,
but curious if there is something sensitive in the P3 I/O area that
can fail easily from a surge, like the old RS-232 circuitry in
Thanks to all my relay stations.
Very few signals on 40 meters.

Hi Dave New,
It does help, and thank you... Mine has come back to life as well,
(power cycling it), and I am worried about turning it off now as well...
I will get an RSA from Elecraft and send it in... I'll report back to
the list what they find, and how long it took to get repaired.

One of the first tests I did after the dual-fuel conversion of my Honda gen
was with the KPA-500. Worked flawlessly, and I highly recommend the
conversion. It only takes minutes:

I had a similar problem with my P3 with SVGA. I had to cycle through the
on-off switch a few times before it would fully power up. Once powered up,
everything was working and stable. I tried reseating the ribbon cables but
that had no effect.
I contacted Elecraft technical support and they
I've been experiencing intermittent failures of the internal
display, as well as loss of at least one setting (Track/Fix).
I've been leaving the K3s/P3 powered on continuously, but recently
started turning them off, to save some 'always on' energy while trying
to figure out why our house
Rick,
A further thought on this... Next time your P3 fails, can you try and
grab an image from it using the utility? I just thought of that, mine
will not grab an image, when it is failed, so it is probably not the
backlight on mine.

Rick,
Thank you! I appreciate the datapoint in this. I was just looking over
the schematic and came to the same conclusion... It looks like a
backlight problem to me as well... I tried to find a datasheet on teh
4538 IC that appears to control it, but alas, nope. I got mine to come
back
My P3 does the same thing. If i keep cycling power it eventually comes
on and works. I suspect there is a bad capacitor in the LCD backlight
power. I have not actually looking into it yet.

A bit more data:
1. The (3 utility can talk to it.
2. If I try and capture an image, it goes through the motions, but no
image is captured.
3. It accepts commands via a keyboard.
4. A load from the last config file did not correct things.
5. A full power off and on did not correct things.
Hello,
My P3 seems to have had a display failure. The SVGA is working, as I
can control the K3 via macros fired at it via the keyboard input. It
failed to light off once before, but that seemed a one off thing, not it
seems permanent.
Has anyone seen this before? If so, what was the
