Dear Elecraft and List,
I got home from a trip yesterday to find the P3 had arrived. A
pleasant and quick build and an afternoon of playing and I am wrapped.
I love the Elecraft approach for top end radios of allowing no solder
kits, it connects me with the technology and architecture in a way
I use the Heil MD2 microphone which has an electret element. I have both
compression and mic gain set to 25, and mic set to front panel low with
bias.
I have far more 'talk power' than I have enjoyed with any previous radio.

I use a small plane / helicopter pilot's headset and my settings are similar:
- bias on
- low
- mic gain ca. 10
- compression between 20 and 25
- reduced bass with the tx equalizer (my voice is very deep)
The lack of SSB-Umph was solved a long time ago, and that BCC report
we wrote way back
**Without using enough compression** (CMP), a lack of SSB average power
level occurs because the ALC does not act the same in the SSB mode as it
does in other radios. This makes the audio sound thinner or less powerful
because there is less very short term (fast speed) compression to level

Try putting a low pass filter in the 28 MHz output path from the K60XV.
Most any with a cutoff frequency above 30 MHz will do.
Sometimes the transverter couples a bit of its output frequency energy
back into the K60XV and overwhelms the power detection circuit. If that
happens, the K2

I've pretty much cut all of the lower frequencies out on my TX EQ and have
gotten very good audio reports. K3 can sound good on SSB but has to be tweaked.

Who uses the Elecraft hand mic? I do and mic gain has to be set low; i.e.
around 8 or 9 to prevent clipping and flat topping as viewed on a monitor

that the hand mics are a tad hot, but mine seems to be excessively

Of course you have to use compression to get any kind of decent punch in your

Why bother? The K3 already provides all of the capability of the

I use my w2ihy box for two reasons

If you're sure you want to step down, you might check out the Ten-Tec
Omni VII.
No complicated menus and very straight forward to operate.
Good QSK. Not as nice looking as the K3. ;-)

Susan,
I am no expert, however I sold an Icom 756ProIII and bought a K-3.
I would not move down to a ProIII if I were you. The K-3 is light years better,
that is of course just my nonprofessional opinion.
Cheers!

Some power supplies, like the Samlex SEC 1235, have no built-in overvoltage

Linear supplies are particularly susceptible, since the pass

Hi Susan,
I love my K3 and it may be worth you trying a little longer to get used
too.
And if I were going to step down in quality to me the next best rig
is the Elecraft K2...not as complicated but a great CW rig.

The K3 actually has a couple even larger transient suppressors built-in. While
they have high peak current ratings, a failed power supply could make them
dissipate hundreds of watts continuously, and fail. If they failed shorted,
the rest of the radio would be protected, but I'm not sure you
Susan,
I think that the days of having background noise from SSB to CW sound exactly
the same are over. They went out the door with DSP, how it processes a signal,
and what it ends up doing with it to improve the quality of reception.
I can only assume what you are trying to say is that

I'd like to clarify this a bit.
While the K3 does have some protection against over voltage on its supply, we
do not garantee it will survive an overvoltage event in all cases.

I'm pretty much done with my testing on decoding PSK31. Using the method I

The noise will normally be different, Susan. The bandwidth is typically
narrower for CW, which means the noise will sound different and be lower in
amplitude for CW.
You aren't the first to complain that the rig is too complicated, but it
need not be. The issue is usually there are too many
I also found my P3 panadapter screen frozen after a period of about 3

Susan, someone else mentioned the Ten Tec Omni 7. I recently used one of
these for several weeks and found it a refreshingly simply rig to operate. QSK
cw is really great and the internal keyer is about as good as the one in the
K3.
There appear to be no major bugs or problems with this
I have completed the last assembly steps leading to Alignment and Test Part
3 and started the testing. Everything went OK until I keyed the transmitter

meter is .5 watts. I do see the current draw rise to about 0.44 amps
I had a thought for a future feature request. For those of us who use RX
antennas (active and/or preamp). It would be really cool if the 12v output
on the K3 could be triggered by the PTT. If the 12v output jack could be
set in the menus to 0v (OFF) on PTT we could power our preamps via that
Hi Rich,
You could control 12 V to an external RX antenna or preamp using the
KEY OUT signal pretty easily. This signal floats (open, or hi-Z)
during receive, and goes to 0 V (ground) during transmit. The timing
is perfect for such an application, because there's a delay between
Something like that (a glow-in-the-dark trim ring for the tuning knob)
could actually be useful on the KX1. Just the thing to make it easy
to find the rig in total darkness without putting additional drain on
the batteries.

Help:
I've finally focused pretty much on what I want for my main
operating station. Until now, it's been pretty
willy-nilly, with different pieces of equipment being
switched on and off the main table. Since Elecraft's
inception, I've been a big fan, and have all their
radios--even two K2's.
