Would appreciate a confirmation...
Are the three (hold - second function) buttons just above the B knob user
programmable function keys?
Thank you.

I have one of the new SPE Expert amps on order:
http://www.linear-amp.com/
It requires 20W of drive for full output. Can one of the knowledgeable K3
designers/testers comment on nominal Po from 160--6M?
Tnx,

Drive power for the Expert 1K-FA amplifier
is Typically 20W for full output. Typically.
I would think it ambitious to expect full output
with just 20 watts drive. Just my opinion.

I've been seeing about 14-15 watts but have not checked on 6m yet. Will do so
this
evening and report back.
So far every contact has reported a very nice clean signal. Excellent CW note
and
audio quality using the 2.8 kHz filter for SSB TX. The TX EQ really makes a
difference as well.
Tom,
All the PSK QSOs so far have been at 3-4 watts.
A nice feature for PSK is having the focus displayed when you adjust the SHIFT
control. So if on your software you have a signal at 1000 Hz, you adjust the
shift
control to 1.0 and narrow down the filter and you get nothing but that signal
Yes. :-)

It would certainly violate the FCC's requirement in 97.317 of 15 dB
maximum gain (although with the loosening of amp restrictions I can't
understand why they left that one in place).

I'm concerned that my SSB output is not matching the set power level.
Reviewing the archive on a search by ALC, I found this note. It's been
years since I've looked to see what scopes are available. Any
recommendations - remembering that cost is a factor.maybe a Scope
that uses the PC.

Why not drive it at 10W and get a cleaner
The best recommendation that I can give for a 'scope is to contact Bob
Garcia at [EMAIL PROTECTED]
Bob is a Tektronics specialist who often appears at SouthEastern
hamfests (he is located in GA) and is well known as Mr. 'Scope. He is
an extremely fair person to deal with and has good 'scopes
Don: Following is not intended for you, but rather for someone without
much experience running an oscilloscope.
I would add one cautionary note. A 10X scope probe usually is rated at
250 or 300 volts, so you might think it's safe to use bridged across a
dummy load with a 100 watt transmitter,
I said the probe tip impedance is only a few hundred ohms, not the 10
MHz it is at DC or low frequencies.
Of course, that should be ... the 10 Mohms it is ...

I have K2 #2481 and just ordered the K2KSB2XTLS did I waste my monies?
I thought the K2KSB2XTLS was a more closely matched set that would give me a
better shape factor than the generic one
Sam,
First, you did not waste your money. It is the motional inductance
parameter for the crystals that is now better controlled (spec with the
xtal vendor) - the crystals have always been matched to the nearest 10
Hz as far as I know. The newer speced crystals are in K2 kits after SN

It's C22 on the control board, but note that the adjustment range is
rather limited and you will not be able to use several of the CAL menu
options after you have made the adjustment.
Will it be possible to configure a K3 to give CW/SSB and a choice of
bands to avoid needing to step through all the modes and bands?
That would be a neat improvement...

Forwarding this to Wayne for a future firmware request. Definitely will not
be
in the first production run firmware.but that's the beauty of a radio that
can
easily be updated.

Hi all:
Help me celebrate!
ARRL DX CW 2007 results are out and my 'lil K2 WON the QRP category for USA/VE.
After log checking:
696 Qso's
244 DXCC

Why am I so thrilled? Because according to the CLAIMED scores, I came
in 2nd. Yup, gotta love log checking! What a TOTAL
I've mentioned before that crystal filters are not perfectly linear
passive devices and can in fact generate intermodulation products. The
reason is that a crystal's motional parameters are not constants, but
rather are a function of the applied drive, something called drive
level dependency
The KPA100 has been spoken for..Thanks

Hello Elecraft QRPers!
I would like to trade my pristine Yaesu FT-817 (not the ND model) for a

There is NO(!) means of significantly re-calibrating the keyer

The Keyer speed control IS a POT... the ONLY encoder is the VFO knob.
