Also for practical reasons, the popular marine bands is near to the I.F. of
K3.
Using K3 for marine communication seems not quite appropriate.

Unfortunately, even if the K3 could be made to operate on marine
frequencies, unless if is type accepted by the FCC for that service, it
is still not legal to use it, whether or not you have a license. As far
as I know, the K3 could not pass the acceptance requirement in it's
present form. T
I know someone who is about to embark on an around the world sailboat
cruise. She is not currently licensed on HAM frequencies but is going
to have a marine operator license. She is about to acquire a marine SSB
radio. Most of those radios are also capable of operation on HAM
frequencies.
Jim and all,
Some just have not "gotten it". The K3 is soundcard digital ready.
Just connect the computer Line in to the K3 rear panel Line Out, and the
computer Line Out to the K3 Line In, and set the "mic sel" menu for data
modes to Line In.

You just spent $20 on something that you could have done equally well

All signal sources are phase locked to this reference, Mike.
The other factor is synth DDS resolution, which is about 1/5th Hz, and
can lead to about a +/- 1 Hz error, worst case, during operation.
However, in diversity mode, both synths are set to the same DDS

Hi Mike,
If you have an appreciation for the elimination of high end artifacts and
overall smother sound, the answer is clearly, 'Yes, it is worth it.' Prior
to the upgrade, I kept the top edge of the filter about 2.35 kHz as that was
about all I could take. Now I have no problem running the
Hello Mike,
The upgrade is a 'must'. I sold my K3#46 and bought back a much newer one with
latest DSP installed. I noted that improvement was far more than described
in Elecraft web page.
The upgrading work is not difficult and well within your expertise.
cheers,

Is it worth it? I have seen some people say yes and others that say no.

I agree. While the website says it meets carry on regulations, it clearly
doesn't. So, if flying with this as carry-on luggage is planned, the

I have just installed the latest production firmware (4.30) and my 2M S meter

Can anyone else confirm this?

Hi Andrew,
Yes. Since the bare enclosure must be ordered as a separate set of metal
from the fabricator (not the same run as the K1 case) and because demand
on the bare case has dropped over time, it does not offset the cost of
ordering and stocking the sheet metal in production quantities.

This is only if you feel the need to have PTT with the hand trigger. I
stick with VOX and just plug everything in to the back connectors. Really
neat and avoids the front clutter. K3 vox is great. Another option might be
