Older option boards from K3 upgrade

michaelstringfellow
I successfully upgraded my late model K3 with the new synthesizer board
(KSYN3A) and KXV3B and have the removed boards with hardware. I guess
there may still be some demand for these - is this a good place to ask?

Re: Older option boards from K3 upgrade

Guy Olinger K2AV
I tossed my old synthesizers, in accordance with my dropping my old
closet hoarder policy of keeping any and all for 40 years to see if it
might be of any use. I actuarially doubt I will see another 40 years.

The synthesizer mod has met with such documented success, that I
routinely advise someone looking for a used K3 not to bother unless
the new synthesizer(s) are in it. Or to work a discount on any K3
without them to offset the cost of the synthesizer(s) to be done
immediately.

All this became apparent very early on after the new synthesizers were
introduced.

Anyone who is adding a KRX3 sub RX to a K3 which still has the old
Synth for the main RX, I tell them to do the synth mod right then,
because the easy time to do that is when the space for the sub RX is
not occupied.

A fully modded K3 is an awesome piece of used electronics, a very good
value. I have noted, watching eBay and sales via this reflector, that
compared to the overall K3 count of nearly 10,000, that only a small
percentage in the low single digits appear to have come up for sale
overall. These days you see one for sale every one or two weeks, which
goes quickly. 25 to 50 units for visible sale out of a universe of
10,000 is a tiny number less than 1%.

I'm sure there are more than that which trade privately. People sell
their K3's to friends and members of their own radio club.

I haven't done the new board that has the built-in sound card and USB
interface. That's because I already have all the stuff working and
debugged to do all those functions without that board, such as true
serial cards in my PC etc. If any of that stuff gets zinged (not
hoping for that), leaving others in a questionable state, I'll do a
wholesale switch to the USB upgrade and remove some number of cables.
Buying a K3S outright requires a financial negotiation with the war
dept, and is highly unlikely unless fire or lightning has turned my K3
into an insurance reimbursement.

In the meantime, my limiting factor is better 160m RX antennas to feed
the remarkable sound-stage diversity possible with the K3/K3S, made
even better with the new synthesizers.

All this contributes to the effectively zero value of the old synthesizers.

73, Guy K2AV

Re: Older option boards from K3 upgrade

Wes Stewart-2
I've seen these rave reviews about the new synthesizer many times.  Has anyone
actually done an A/B comparison in real time with two otherwise identical radios.

I have a K3 with the original synthesizer (the actual one used to develop the
stiffener plate) and a K3S.  I have not run them side-by-side since I don't have
any test equipment with sufficiently low phase noise to use.  Anecdotally, using
them one at a time in day-to-day operation, I haven't noticed a difference.

Wes,

I know of no A/B comparisons, but the Sherwood chart shows a significant
improvement - he has rankings for the K3 with and without the new
synthesizer.

The lower phase noise may be apparent to you when picking a station out
of a pileup or on a contest weekend with many close-in signals.

The transmitted phase noise is also reduced, so your ham neighbors might
notice a difference in the width of your transmitted signal.

73,
Don W3FPR

Many times, with spectrum analyzer screen prints, etc. Some of those
in the near-astounding category.

At this point can't refer you to them but you can find them with some searching.

A 3 dB improvement in TX strength will not be noticed either, until it
is used in a situation where you're close to or in the noise.

Close neighbor hams with a sequence of installing the syns, and screen
prints in the reduction in phase noise sidebands for each step, and
noticeable improvement in interfering with one another. For me that
was the killer demo.

The "news" aspect of the syns is pretty well past, so don't see much
about it any more.

Ok,

Since I'm the one in the pileups, don't contest and my line-of-sight contesting
neighbor runs an ICOM IC-756 PRO III to an ALPHA 8410 he deserves whatever he
gets:-)

Seriously, if I can figure a way, I'll try to do some real world comparisons.

Guy:

All noted.  I just hate to trash perfectly good boards when there might
be someone who could use them.

Not everyone will need the latest KXV3 if they're not too bothered about
ten and six meters and it's possible someone could even use an old
synthesizer board.  They are still installed in the majority of K3 rigs
out there and, as others note, work perfectly acceptably for most users.

Re: Older option boards from K3 upgrade

Guy Olinger K2AV
Roger that. I missed the KXV3 in your post. I upgraded to KXV3B and
gave my now spare KXV3 to a friend filling out a K3 he picked up.
Friend had to pay for the shipping plus a cool one for the trouble of
going to the post office.  :>)

Don't throw away the KXV3. Just throw away the Syn boards.

The improvement in QSK performance and elimination of jitter in CW timing was immediately noticeable even without an a/b test. Night and day.

Re: Older option boards from K3 upgrade

Guy Olinger K2AV
The second K3 listing from top on the Sherwood (old syns) vs the first
K3 listing from top (K3 modded with new syns) is as good an A/B RX
test as you will ever get. Note: there is a separate K3S listing.
Print out the first page of the Sherwood listing in landscape mode,
and then fold the paper to put the two listing lines next to one
another.

It is quite true that many typical and ordinary ham situations will
not demonstrate the difference, but weak signal work on any band,
those improvements will make a difference, because phase noise is not
additive, it modulates band noise. This will have more effect on
signals from low signal RX antennas that are not pre-amped.

My K3 with the new syns is better in sound stage diversity, but that
is in the brain and I don't know the mechanism for the improvement,
hence entirely subjective. I suspect something related to allowing
band noise to come through less modulated by phase noise, but
absolutely zero proof.

On a diversity sound stage, noise is scattered around the "horizon"
with some discrete noise taking fixed positions. The noise sounds less
"muddy" with new syns, that's as good as I can describe that.

I'm still trying to find a series of attachments showing a progression
of phase noise on steady TX carrier with one at a time syn changes
between two close K3 owners. I'm now thinking it was on one of those
Tiny URL kinds of things and perhaps not widely distributed. I don't
have email with attachments regarding that synthesizer test.

And I'm one of the worst at figuring out the secret word to pump a
google search.

And yes, the diff in CQ shaping was obvious in seconds after syn replacement.

There is some stuff on Elecraft's Nabble searchable list showing A/B keying.
