In MSK144 the T/R periods for meteor scatter are normally 15 seconds on 50 MHz,
so it is important for all stations to have their clocks as accurate as they

You will get spikes with no antenna where they are not covered up by band

turning down the NB level in THE PX3 or turn the PX3 NB OFF.

David,
This happens when SSB + CW is enabled. In CW WGHT menu tap 1 to toggle between
SSB+CW (enabled) and SSB - CW
Tapping Keyer/Mic knob toggles between Keyer speed and Mic Gain rather than
Meter Scales CMP/ALC and SWR/RF. The CMP/ALC scale is still shown temporarily
when CMP or Mic Gain
Barry,
You can set the KX3 up for single button message send.
* FAST MESSAGE PLAY: A long-hold of MSG (~3 sec) puts the KX3 into FAST PLAY
mode. In this mode, the BAND+, BAND-, and FREQ_ENT switches can be used to
play/repeat messages 1, 2, and 3 immediately, without the need to first tap
George, check that Data is set to DATA A. (Change it using the VFO B knob).
Also widen the filter passband when in DATA mode and it should work. Also make
sure that you have DATA A set to USB and not LSB ( Hold ALT to change it from
one to the other). There are advantages in DATA rather than
I seem to recall they could produce cyanide fumes. Best to use good ventilation
and a fume extractor fan with filter if you are doing a lot of them. I like the
smell of solder flux, but after reading about the health problems they can
cause I invested in a fume extractor here.

Hi John,
That is normal, as the KX3 is a direct conversion receiver and the LO can
radiate through the antenna, however to reduce this Elecraft have put in an
isolation preamp which you can enable and should reduce the level of this. Try
changing RX ISO to ON in the KX3 menu.

Hi Oli,
I agree it looks like there is no point in paying for the TCXO-3 if you have a
reliable constantly available 10 MHz external reference. Perhaps they recommend
the better TCXO as a better fallback if for any reason the external ref is not
available, I can't think of any other reason for
Oliver, I was wondering about this, I guess it is just that the short term
drift is lower so it won't drift as much between frequency measurement
corrections which are made for 1 second every 4 seconds according to some info
recently published. I doubt it matters much though. I would be tempted

Coincidental I think hi. Yes Aurora on 144 MHz here this afternoon and the
magnetometers showing the impact too.

Dick,
I found the reference to that figure I quoted, it is in the K3EXREF manual:
The K3EXREF option locks the K3's reference oscillator frequency to an external
10 MHz source by automatically controlling the REF CAL function. While locked
to the external source, the K3’s reference oscillator
