Hi Chris,
not changable, it's by design. :-( The "clipping" sound is due to the NF
stage which limits at about 4 kHz. The KX3 is much much better in that
respect.

On your filter setup in the K3 utility, set Freq Offset to zero to start.
Set bandwidth to 13, and check "FM Enable".
Also make sure that the FM filter really IS in slot 1, and that it is
properly seated.
73, and good luck

I have just started using 2 metres FM on my K3 #685.
The receive audio is rough and distorted, it sounds as if its being clipped.
The FM Inrad filter is .in slot 1 and FL1 is showing.
By comparison, my Yaesu FT3000 and FT817 are qute undistorted on the same

K3 SSB audio is fine.

Fred,
What that means is that at 30 MHz, the amplitude is reduced by 3 dB.
Usually, such a 'scope is useful for determining if there is a signal
(assuming the 'scope has adequate vertical sensitivity), but should not
be used to measure signal voltage with accuracy above about 10 MHz.

Ron,
Welcome to the Elecraft reflector.
If your 'scope is capable of seeing a 50 MHz signal of 100 mV peak to
peak amplitude, yes you should see a good 50 MHz signal from the
oscillator Z2.
If you have no oscillator there, and you measure 2.7 volts in Z2 pin 4,
you may have a bad oscillator -
Ron I have no comments about the KX1. However I do seem to recall the Tek 422
has a 30 MHz bandwidth with a P6006 probe.

For beaucoup power from a KX1, you can use a 4S1P A123 pack, and even recharge
it remotely with a small solar panel and a Genasun controller. Mine puts out
well over 5 watts with this setup, however Wayne has said this much power can
endanger the finals. So far, no problems. It is a bit bulk

Rich is correct. The K3 shifts the carrier frequency between AFSK and
AFSK REV (of FSK and FSK REV) but fails to account for the the exchange
of mark/space tones.
To be rigorous, MMTTY and the K3 should probably use 1275 Hz Mark in
AFSK (lower tone = higher RF frequency) and 1445 Hz Mark in AFS

In AFSK A the K3 displays the actual Mark frequency on its dial, not the
suppressed carrier or BFO frequency as it does in DATA A.
I believe what is happening is the following (this is the same as what Joe

Mike,
Do you have MMTTY set for 1445Hz Mark *and* the K3. Hold PITCH button
to check/change.
That would make a difference in AFSK A, but not in DATA A mode

Using DATA A, which really does swap sideband results in a near 3k

switched from LSB to USB.
It is.
It looks like keying is reversed but shifted in frequency on the
waterfall by one keying shift value eg 170Hz. However, whilst

Guru's,
Trying to get a handle on a problem with frequency reporting in MMTTY.
Not an operational issue, I just don't take any notice of MMTTY

There is no Y cable needed for the RS-232 interface. The RS-232
connector from the microHAM cable connects to the P3, the P3 connects
to the K3 via the Elecraft RS-232 cable supplied with the P3.
For best results configure the K3, P3, microHAM Router and your logging
software to operate and 38.
I am in the process of interfacing my new microKeyer II to my K3, P3 and
KPA500. I would like to correspond with someone that has an operational
system of this type. I believe I might need an additional Y-cable for the
RS-232 interface. Please respond off line to orville @ rubyglass.com.

John,
That is not normal. You might want to check a couple things.
First, connect an external wattmeter and monitor the actual output - set
the power control at 50 watts and see how much power you actually have
on CW keydown.
If it is much higher (greater than 100 watts), you have a problem wi
Remember that there is an option on the KPA100 to have the fan run
continuously at low speed. This keeps it cooler and cuts down on
number of times it kicks into high gear. Still sounds like a 747
winding up for take-off in those instances, but it does help.
Maybe a large, quiet, external mu
I ordered a new top cover for my KX1 and installed two LiPo batteries into
it. Though the exact model of battery is no longer available I'm sure there
are others that will fit:
