Don,
The KPA100 is new -from Elecraft in September 2010 - and it therefore is the new
design with the blue toroids @L16/RFC1. The shield is installed as instructed,
using the 2 solder lugs to the SO-239 socket.
I took the KPA100 off the top of the rig, as you suggested, but there is no
differenc
APF works well I think and its button access is properly placed on the front
panel. What would make access easier for those who think changing between APF
and Dual PB on the fly is necessary, would be to make the Config Menu remember
its last setting after a power cycle.
One could then leav
Just info how I am using APF on/off:
I am not using XFIL/DUAL PB button for APF activation/deactivation
during standard operation.
I have pre-set NORM I as 400Hz roofing w/o APF and NORM II as 1khz
roofing with APF.
So only switching between NORM I/II activate/deactivate APF, then I
can change w

And this will also even work when config DUAL BP is switched to normal. You
will have APF on/off on I/II and Dual BP on Long Press of XFIL. That's how I
use APF.

Holger,
There is the possibility that the wattmeter in the KPA100 is not
properly balanced and calibrated, and deserves to be re-checked.
Calibrate the wattmeter at 80 watts rather than at 100 watts for best
results.
You can expect some variation in the response of the wattmeter diodes

Re-transmitting (on-the-air) an SSB signal that has been recorded on-the-air
results in a very "pinched" audio through the DVR monitor and a slightly
pinched audio reported by those receiving the play-back. The re-transmission
is no longer the faithful reproduction it used to be.
However, the

John,
At this point, check the audio drive and the SSBA menu parameter - which
should be at 1 for the MH2 (or other electret microphone). SSBA = 2 and
SSBA = 3 are both the same and are normally not used with these microphones.
If you have any audio preamplifier installed, remove it for use
Yes, this has been a problem here since I got my K3 about a year ago.
Others have noticed it when their audio is played back to them making
playback on the air almost useless for quality reports.
I have reported this problem but nothing has been done to solve it.
Hopefully the problem will be fi
I think I posed this question before. Does the DVR audio recording get
passed thru the TX EQ currently set? Or does the TX EQ get set
temporarily to "0 0 0 0 0 0 0)? I think this would be the best IMHO. I
have made recordings with two different mics, and then they were
played back, they did
The DVR is AFTER the receiver filters (so ti records what
you hear) and BEFORE the tramsmitter filters (so your
voice sounds the same as if you were using amicrophone).
Thus Rx EQ, notch, APF, etc affect what you record, and
Tx EQ, compression, etc., affect what your transmit.

Hi,
I have a problem with my KX1, I notice that if apply some minor force to the
covers my audio level will vary. This sometimes appends if I tap the main knob.
I did a full soldering rework and still no solution.
Any ideas please.
Best regards,

A quick and easy search of the archives brought up this reply from Lyle
dated June 22 to an earlier post:
"The DSP treats all TX audio sources the same: FP MIC, RP MIC, Line In,
and DVR. TX EQ and/or CMP will be applied if active in the current mode."

My view is that the RX situation is fine i.e. you want to record
what you hear. However, I think on TX it would be useful to have
the option of either:-
a) Replaying exactly what you heard - e.g. for other station audio
b) Replaying through the EQ, Compression etc - e.g. for contests

Do you have the KXB3080 (or KXB30) option installed? If so, be certain
the wires on the top of the option board have been flush cut and the
square pads are in place. If the transistors under that board are not
down flat against the main board, they will not allow the KXB3080 board

OK, sorry I missed that in the archives.
Maybe this question is covered before as well, but here goes. When
recording with the mic to make a recording to re-TX, is EQ applied to
this? I'm trying to determine if the EQ is applied twice, or just
once. Maybe I should make the recordings with TX

doesn't boot which results in no audio out but when I power the

The speed is right but even strong sigs it´s hard to find the point and decode
it.
Also the manual says to move the WIDTH from.50 to 100-200hz but

Greetings Fellow Elecrafters,
With great anticipation I finally got around to assembling my P3 (SN 211) last
weekend. Assembly went great and power on tests were encouraging.
Unfortunately, it fails to display any output from the IF output port on my K3.
Nothing. Every function seems to work

Forgive the implication of stupidity :-), but you are connected to the
correct bnc connector on the back of the P3 are you?

Dave,
Behavior like that is "by definition" intermittent (sometimes it works,
sometimes it does not), and usually can be traced to some connection.
Do not ignore the connectors. Usually, they will wipe off any oxidation
by simply removing and re-seating, but at times, more drastic action is
Scott,
We will have to narrow things down a bit to be helpful - so we need more
detailed information.
You say you can "change bands", but you also say that the relays on the
RF Board do not operate - those two statements are not consistent - the
relays must operate to actually change bands.
