Re: [Elecraft] KSYN3A Synthesizer

[Dave Cole (NK7Z)]

Hi,
I was actually very fortunate-- he upgraded from his Collins gear to the 
Elecraft K3, then to the new synthesizers.  He only got to use his K3 
gear for a year or so, then he passed suddenly.  His son in law got the 
K3, and loves it, so the rig got a good home.


73s and thanks,

Re: [Elecraft] KSYN3A check

[Ian White]

Hi Ian

First, make sure that CONFIG: TECH MD is set to On. You won't ever
need to change that again.

Got to CONFIG: DDS FRQ.  If the display shows 3.58something, then
you have the older KSYN3. If the display shows - - - - then it's a
KSYN3A (which doesn't have a DDS).

Use a 5" or 6" TMP cable and hook it from J6 on the KREF3 (same as old

[lstavenhagen]

It would be the graphic in figure 12 on page 15 of the instructions. It hooks
up with just one tmp cable and the long one isn't used. 

It all looked like spaghetti to me too when I did the upgrade on my K3, but
that's the figure that shows the hookup for no 2 meter module and no 2nd
RX.

Re: [Elecraft] KSYN3A and QSK

[Guy Olinger K2AV]

Yes, RIT is off as are some other features for QRQ mode.

With the new syn QRQ mode becomes finally what it was intended for, a
speciality mode for doing 80 WPM full break-in. And the ridiculous less
than one millisecond TX RX TX state change budget, required to hear between
bauds at that speed, mandates a no-frills necessities only lean and mean
state change task list in the programming executed between bauds.

I would think that it's time to drop the confusing old/new QSK distinction
if new Syns are detected. Or keep and call them smooth/sharp or some such,
sharp being I want to hear as much as possible between bauds, smooth being
hear as much as can without clicky or popping sounds.

Non QRQ mode is significantly improved with the new synthesizer and many
think contest operating to 35 or 40 WPM don't gain anything by switching to
QRQ mode.

OK.  It works with headphones, and Craig at Elecraft told me to change
SPKRS=2 to SPKRS=1, and now it works.  I think it probably never worked
with the speaker, and as I always use a headset, I never noticed before.

Thanks to Craig for the help!

Chemicals intended for use around electronic components, including PC
boards, have been formulated according to an industry-wide "Non
Aggression Agreement". This aims to ensure that chemicals such as flux
cleaners and contact cleaners will not damage the plastics that are used
in the majority of components. In return, component manufacturers try to
avoid using plastics that would be damaged by solvents in common use. 

Undiluted acetone is not part of that agreement because it's simply too

Re: [Elecraft] KSYN3A mod problem

[David Woolley]

PCBs (FR-4) are glass reinforced epoxy, not polyester (I think the old, 
brown ones (SRBP) are paper reinforced urea-formaldehyde).  Also the 
resin component is cross-linked, whereas the article is talking about 
thinning the uncured (un-crosslinked) resin. (Glass reinforced polyester 
is used in car body repairs because it is cheaper than epoxy.)


I'm not saying that acetone is a good thing to use on electronics, only 
that the rationale in relation to PCBs is flawed.


Incidentally, methanol, an alcohol, softens, but doesn't dissolve, cured 
epoxy.

Polyester resin, also called gel coat, in case you don't know, is the stuff
PC boards are made of. Leave acetone in the paint department where it
belongs. I suggest alcohol, any kind as long as it pure, be used for
de-fluxing PC boards.

When you purchase alcohol to use as cleanup it's best to get the highest
concentration you can get, else, there is a risk of it leaving a residue and
the evaporation rate is much slower. Most drug stores sell 91% or higher if
you ask/look for it. 60% is more common. Higher % is better for cleaning and
evaporates more cleanly.

Chemicals intended for use around electronic components, including PC
boards, have been formulated according to an industry-wide "Non Aggression
Agreement". This aims to ensure that chemicals such as flux cleaners and
contact cleaners will not damage the plastics that are used in the majority
of components. In return, component manufacturers try to avoid using
plastics that would be damaged by solvents in common use. 

Undiluted acetone is not part of that agreement because it's simply too
aggressive, as Fred describes. 

Although electronics-grade solvents are more expensive than bulk commodity
solvents like acetone, for peace of mind they are worth the extra cost.

Not quite.  Pure ethanol is a *practical* impossibility.

 https://en.m.wikipedia.org/wiki/Everclear_(alcohol)

It comes in 75.5 percent (151 proof) and 95 percent ethanol (190 proof) 
varieties.  Sale of the 95 percent is banned in some states.

The 91 percent drug store denatured alcohol would be as good a choice for all

Re: [Elecraft] KSYN3A mod problem

[David Christ]

One other thing to consider that can make a difference in some cases.  There 
are three types of alcohol commonly available.  Methanol often used as shellac 
thinner, ethanol, booze if you wish, which EverClear is, and isopropyl which is 
often found in rubbing alcohol sold in drugstores.  They vary in toxicity and 
can react differently with some materials.  You chemists out there can 
enlightens further.

Re: [Elecraft] KSYN3A mod problem

[Hisashi T Fujinaka]

You can get denatured alcohol from the hardware store, but I think that
can contain methanol which I wouldn't suggest using because of toxicity
and because it melts more things than ethanol. Methanol will go through
your skin so you need ventilation and the correct gloves.

Rubbing alcohol from the drugstore can contain some oils that you don't
want.

If you can get Everclear in your state and you can afford the tax on it,
I'd say buy that.

Re: [Elecraft] KSYN3A mod problem

[Fred Townsend]

Gentlemen: 
Water is not a problem. You want the water to pick up the water because
alcohol is a non-polar solvent meaning it does not pick up the ionic
contamination. The water picks up the ions and alcohol picks up the water.
Conclusion rubbing alcohol containing water works just fine although the
50/50 cheap stuff now sold is not as good as the 70/30 or 91/09. Best way to
clean is to blot and or air squeegee the liquid off. Don't let it evaporate.
That leaves the sold residues behind. When finished cleaning if you still
have worries about water then bake out your board at 90 to 95 degrees C. 30
minutes is all that is needed.

Nick,

Yes, but it fails when it cools again - something is not making good
contact, and it may be residue from the cleaner.  I can't be certain of
that, but I would get that cleaner residue off and try again.

I would suggest that you remove the cleaner residue from the contacts with
acetone - apply it with a brush or cotton swab and immediately wipe the area
with a clean cloth of paper towel.  Do only a few pins at a time, and do not
let the acetone dry on the contacts or board.
You may want to mate and unmate the front panel and RF board several times,
cleaning between each to hopefully clean some of the 'goop' out of the
female header.

If you do not have gold pins on the connector to the front panel, consider
asking Elecraft for the gold replacement pins.

Yes, alcohol can do a good job of cleaning flux too, but needs to have the

Dip an opaque object in alcohol and remove it with a paper towel - note that

Besides, the job for the particular problem stated was not flux removal, but

Re: [Elecraft] KSYN3A mod problem

[Don Wilhelm]

Nick,

I don't think it is related to the synthesizer, but go through the other 
things you did (cleaning the Front Panel connector and some other 
boards) - you should unplug those, and depending on how you "cleaned" 
the connectors, wipe them carefully and reassemble.

Work on each connector one at a time and test again after each one.

Don W3FPR

Hi,
have replaced old synthesizer in my K3 for new KSYN3A and have problem with

Changing frequency by VFO A or VFO B several kHz up or down switches mode
to reverse
(CW to CWR, USB to LSB), frequency on display jumps 1 mHz lower ( ex.
14015.00 > 13015.00,
1830.00 > 0830.00 etc.) and band pass filters relay click can be heard at
the same moment.
After switching 1 mHz lower rotating VFO A frequency changes as it should,
nothing clicking, mode is not reversing but radio is far away from amateur
band.
After keeping radio an hour or so on and warming it up problem disappears.
K3 has no sub receiver installed. Firmware 5.33
Front panel connector and some other on boards around synthesizer were
cleaned.
When I put original synthesizer back problem didn't disappear and was
exactly same as with new unit.
I would appreciate any ideas to locate and fix this problem.
Thank you in advance

Re: [Elecraft] KSYN3A dead?

[ok1rp]

Hi Enrico,

The correct status for KSYN3A boards in TECH MD: ON is OK! So you should see
SYN1 OK and SYN2 OK if you have both installed. The latest KSYN3A boards
should work with 5.14 or later.

Please open K3 and at first check if your cables are connected to right
boards (not swapped by accident) and if all connectors are properly plugged
in and have proper contacts please. It is common issue the TMP connectors
has bad contact on the synths boards.

Hope it helps,

73 - Petr, OK1RP

Re: [Elecraft] KSYN3A dead?

[Enrico Lorenzoni IU3AZC]

Hi Petr, I have two ksyn installed, and both worked fine for some months.
I did not open my K3 in the last weeks, and two days ago my K3 was ok, 
so this happened without touching anything.
An italian OM had another problem with a deprogrammed SYN. I wonder if 
Elecraft is aware of this and who's gonna pay the cost to reprogram it?


thanks for the reply

Hi Enrico,

aha, so it sounds like more serious issue. 
I never heard about the issue with erased synthesizer but if it happened to
your friend then its time to contact Elecraft.
I am so sorry that I can not help you more my friend.
Let us know please about the progress.

Re: [Elecraft] KSYN3A + KSYN3

[Thomas Schaefer]

I just went thought this process and the new KRX3 comes with the new synth. I 
had to pick up a new synth to replace the old one in the main receiver as they 
have to match. 

It only took 12 hours to do it all including redoing the filters in the 
receiver because I did not read the manual close enough and my 
mis-understanding of the implication of “optional steps” regarding the 
connection to the KAT3 tuner for the KRX3.

Hence, I am the cautionary tale about not reading the manual :)

But, I will say that doing this work makes me sorry I did not buy the kits for 
both K3s--that would be the plural of K3 versus a K3S :). It was GREAT FUN to 
install the sub receiver. I really enjoyed the fact that when someone was 
explaining routing the TMP cables, and installing the new pre-amp, I could see 
the exact parts and how they fit together. It made something abstract quite 
real and I like that.

Re: [Elecraft] KSYN3A + KSYN3

Russ,

If you install the KSYN3A for the main and then add the KRX3, you must 
have the KSYN3A for the sub as well.

You cannot mix the synthesizers - they must both be the same.

Cheap/thrifty/cost effective does not matter, they both need to be the same.

Per the KSYN3A Installation instructions:

You cannot have a new KSYN3A synthesizer and the original KSYN3 in the 
same K3!  If you have the KRX3 sub receiver installed, you must install 
two KSYN3A synthesizers.

Re: [Elecraft] KSYN3A + KSYN3

As a cautionary tale, reading the instructions is really not optional with this 
stuff :)

If you decide to install the KRX3 for example, there are lots of little gotchas 
in the KRX3 install that are easily avoided by reading the directions. Not 
doing so is certainly at your own peril.

Re: [Elecraft] KSYN3A

I installed two new SYN3A's yesterday in K3 #1255

A very positive surprise: The diversity mode has improved a lot. The 
'woosh'  during tuning has competely gone! Super.

A negative surprise: Tuning noise on 40m (S3 !) plus birdies.
I will install the tuning noise reduction mod (of 2009) now and see 
whether that helps and i'll move the TMP cables around to improve on the 
birdie problem.

Re: [Elecraft] KSYN3A tuning noise on 40m

[Wayne Burdick]

The K3 has very high dynamic range, requiring a high-level local oscillator 
(the synth). One way to minimize spurs (birdies) in a superhet design of this 
type is to include very narrow-band filtering, which we used throughout the 
radio. The ham-band filters are all just a bit wider than the ham bands 
themselves, there are multiple I.F. rejection traps, and there's a very narrow 
triple-tuned filter on the noise blanker.

The other way to minimize spurs is to enclose every subassembly in its own 
shield and connect them when coax cables. While we use shielding where 
absolutely necessary, we tried to avoid extensive shielding because it would 
have dramatically increased the size, weight, and cost of the K3. Instead, we 
used careful PCB layout, just the right number of coax cables, and balanced 
low-pass filtering in the first mixer that rolls off the VHF and UHF synth 
harmonics. The combination of these techniques results in very few spurs within 
ham bands.

Those spurs which persist are generally very low level, inaudible with any kind 
of antenna connected. For any fast-tuning (VFO harmonic-related) spurs that 
remain above the noise floor, we provided the CONFIG:SIG RMV menu entry -- a 
variation on spur-mapping that can be quite effective. 

It's not surprising that certain very low-level spurs would change in level 
with repositioning of the coax cables, since they typically arise from UHF 
harmonics of the VFO.

Wayne

 My experience has been that the tuning noise is strongly affected by the

 I had heard some slight tuning noise on higher bands with the old KSYN3's, 
 but only with no antenna connected, which is not a realistic test. After I 
 put the new KSYN3A's in, at first I had much higher tuning noise (a buzz or 
 rapid clicks when turning the tuning knob), but I opened up the rig and 
 repositioned the TMP cables and since then the tuning noise has completely 
 disappeared, even with no antenna connected.
 
 I do not have the VFO tuning noise reduction mod installed.
 
 As for the rapidly tuning birdies (the ones that can be eliminated with the 
 CONFIG:SIG RMV option), I have not done a careful check. However, while they 
 may appear at different places than they did before (perhaps that might be 
 related to a reference oscillator adjustment), they do not seem to me to be 
 any worse than they were with the old synth boards.

Is this with or without an antenna connected?  What's the nature of the 
noise on your spectrum analyzer? Broadband or with humps every 10-20 
kHz? Do the peaks drift? Remember that our world is full of switch-mode 
power supplies spewing out trash on harmonics of their square waves, and 
the lower we go in frequency, the stronger they are.

Re: [Elecraft] KSYN3A Synthesizer problem?

[Wayne Burdick]

Roger,

More on this...

Since KSYN3A buyers may not always see the FAQ, we'll be adding something like 
this to page 1 of the KSYN3A installation manual:

* * *

Note on K3 low-frequency (100-400 kHz) receive coverage with the KSYN3A 
installed:

With a KSYN3A installed, the K3 VFO can be tuned as low as 100 kHz. Sensitivity 
will be very good in the 600-meter band (470 kHz) if a KBPF3 filter module is 
installed, and the antenna is connected to either the RX ANT IN or XVTR IN jack 
on the KXV3 module. However, below 300 kHz, sensitivity starts to decrease 
quickly, because the K3's receiver was optimized for use on higher bands. 
Typical sensitivity at 300 kHz will be about -100 dBm. The preamp should be 
turned off at very low frequencies because it is not useful here; it will only 
increase noise level.

* * *

Let me know if you think further clarification would also be helpful.

Thanks,

Wayne

Re: [Elecraft] KSYN3A Synthesizer problem?

[Wayne Burdick]

Hi Roger,

The noise floor is coming up because the RX circuitry was optimized for use 
from 250 kHz and up. Multiple sources start contributing significant noise 
below 250 kHz.

Even though the new synth tunes down to 100 kHz, we tried to make it clear in 
the KSYN3A FAQ that the receiver isn't very sensitive in this range. It does 
very well in the 600-meter band (472 kHz), and has reasonable sensitivity in 
the 300-450 kHz range where there are many LF beacons.

To quote from the KSYN3A FAQ:

 Q: What is the K3's 100-490 kHz receive sensitivity?
 
 A: With preamp OFF, we measured about -125 dBm at 475 kHz

At 250 kHz the sensitivity is about 10-20 dB lower, and it will go down from 
there. Yours is better than our baseline measurement. 

The FAQ entry continues:

 We have not measured MDS below 250 kHz, but the receiver will gradually 
 become less sensitive as you go lower in frequency due to band-pass filter 
 roll off (in the KBPF3, which is required for operation below 160 meters). 
 These tests were made with the signal routed through the RX ANT IN or XVTR IN 
 jacks on the KXV3 option module.


It would be possible to redesign the KBPF3's lowest-frequency filter to improve 
sensitivity below 250 kHz. However, the receiver uses PIN diodes extensively, 
and the rolloff from this band-pass filter helps prevent intermod in the diodes.

I can see that we should clarify this topic further in the FAQ and installation 
manual.

73,
Wayne

Re: [Elecraft] KSYN3A newest firmware : VCO:MD menu entry still there and delivers error

Eric, thank you.

I think I have read in the release notes that the item VCO:MD does not 
show up at all if the firmware has taken notice that a KSYN3a is installed.


Maybe something more for the todo list .. :-)

Re: [Elecraft] KSYN3A Install

And also make sure you download and follow the revised instructions and 
Errata from the Elecraft website.  Do NOT follow the printed 
instructions shipping with the boards (unless they match the website 
revisions).


Note also that if you have the 2-meter phase-lock option, the REF OUT 
cable is removed from the 2-meter module and not used.

Re: [Elecraft] KSYN3A Install Doc Suggestion

[Gary Smith]

If that ain't the truth!

What I do with things like putting those split washers into a hard to 
access situation is to take a piece of tape, put the sticky side on 
my jeans, pull it off with the accompanying lint and then pressing 
the washer onto the tape. It'll hold the washer in place and let you 
align the washer properly but won't grip onto it so tightly it's a 
problem to pull out after all is in alignment. Hemostats are 
invaluable to holding the tape just so.

As you mentioned, we don't have to do this when installing the 
replacement boards but it's a neat trick that works great. Just 
thought this would be a good time to mention this little trick, when 
you do need to deal with that kind of an issue, it saves a lot of 
swearing...

Re: [Elecraft] KSYN3A and below 490 KHz?

[Edward R Cole]

Would not an external preamp designed for 100 KHz not improve 
sensitivity?  Many operators use small loop antennas with preamps on 
both 600m and LF.

The latter. Sensitivity gradually decreases as you do down in 
frequency, and you start hitting a practical lower limit for the 
receive chain.


The preamp is not useful below 500 kHz, and will actually introduce a 
loss when turned on, so it should be left off in this range.

Ross,

There a quite a few (50 or 100) hams happily operating on 600m, 
currently.  Not as hams but by obtaining an FCC experimental 
license.  If that seems too daunting a prospect, help is available 
for filing out the application from those who have already done this.

Re: [Elecraft] KSYN3A - installation question

[QUENTIN COLLIER]

I apologise for this being off topic, but this (which my son told me - I blame 
the parents...) had me doubled up.

Schrödinger has had a bad day at the lab, and is driving home somewhat 
erratically. So a policeman pulls him over and breathalyses him. The policeman 
says well you're sober, but do you mind if I take a look around the car? 
Sure says Erwin. A couple of minutes later the officer comes back and says  
well, the car's OK, but did you know there is a dead cat in the boot? (Perhaps 
I should say trunk, as this is predominantly a US website...) Well, yes, there 
is NOW says Schrödinger.

One day I will make a useful contribution to this list

It is quite easy to swap the synthesizer boards without removing the KRX3 module. I did it blindfolded with a long-haired cat on my lap and the latest Tom Petty album blasting away.

The total shipping cost to a company consists of not only the cost of 
packaging materials and postage, but also the salaries of the staff who 
take the order, process it and the hands that put the items in the 
package and apply the shipping label.

Re: [Elecraft] KSYN3A

[Anthony Scandurra]

I also suggest that everyone should consider the other shipping options
available.

I chose USPS Priority Mail, and it was significantly cheaper than UPS
Ground.

It pays to look at all the options.

 I consider the handling part of Shipping and handling to be
 equivalent to the effort assembling a part  paying the company for
 doing that. The shipping is a fixed price for a company and the
 company has to pay staff. Not to charge for that order acceptance and
 handling time means the company donates that money from their budget
 and processing that order is a loss for them.

 I too noticed the cost of shipping when I ordered the two KSYN3A and
 AM filter but I go back to my earlier post where I said I want
 Elecraft to succeed and prosper. They can't prosper giving away the
 order department and shipping department's services.

  The total shipping cost to a company consists of not only the cost of
  packaging materials and postage, but also the salaries of the staff who
  take the order, process it and the hands that put the items in the
  package and apply the shipping label.

Re: [Elecraft] KSYN3A - installation question

[Jim's Desktop]

 I looked it over and the only reason you would have to remove the KRX3 
is if you had it installed but were only buying one KSYN3A.  You must 
have the same synthesizer installed for both receivers.  If you just 
change out the main receiver's synthesizer, you then must remove both 
the old 2nd RX synthesizer AND the receiver or you will confuse the K3's 
MPU and it won't work.  That was the gist of the previous thread.

Re: [Elecraft] KSYN3A

[Ray Sills]

13 ounces (the limit for First Class Postal service packages) is  
0.8125 pounds, so it might be possible to -mail- the new board and not  
use UPS.The postal service would be cheaper, but you'd have to add  
insurance, so the price might be a toss-up vs. UPS.  If the board  
would fit into a small Priority Mail box, (likely), the cost would be  
less than First Class.

Re: [Elecraft] KSYN3A (shipping)

[GRANT YOUNGMAN]

I find it a bit humorous that the subject invariably arising for a $200 (or 
$1000 or $10,000+) item ends up being about chump change on shipping costs.  
We’ll drop a bundle on something and then spend hours quibbling about a few 
bucks on shipping.

I’m not a terribly sophisticated user of my K3 compared to some of you, but my 
K3 has all of the available options, all of the mods installed, and the latest 
revs of everything (I know about).  I have two of the new KSYN boards ordered.  
Last thing I worried about when I placed the order was shipping cost.  

Maybe it’s just a need to find SOMETHING to grumble about.  I spent more on a 
few (losing) PowerBall tickets that garnered nothing in return.  At least I 
know I’ll get a box in the mail from Aptos :)

Grant NQ5T

 
 Actually Priority Mail travels as first class and the flat rate boxes and 
 envelopes are good for up to 70 lbs.  Comes with tracking.  The limitation 
 is size.  The envelopes and small box are under $6.  Where they can be a 
 real bargain is if you need to mail something to Alaska or Hawaii.  Same 
 price as across town.
 
 $50 insurance is included, $200 is $3.30.

Re: [Elecraft] KSYN3A - installation question

[Harry Yingst via Elecraft]

I found that installing the sub reciever is a lot easier with the handle side 
of the K3 removed.

 Subject: [Elecraft] KSYN3A - installation question
   

First question that came to my mind when I saw the announcement was
whether the KRX3 had to be removed and reinstalled in order to replace the
synths.  I found installing the KRX3 exasperating when I assembled the K3
- success came on about the 12th try.

My K3 is 100 miles from where I am right now, so I looked at the photos in
the K3 assembly manual and those in the new synth instructions, from which
it appears that the swap could be done without removing the KRX3.  Could
we confirm whether RR is required?  Message below says it is.

If the sub does have to be RR¹d, anyone have suggestions about how to
reinstall it without the major fuss I experienced?

unplug it and remove its ?old? synth board.  . . .

Actually Priority Mail travels as first class and the flat rate boxes and 
envelopes are good for up to 70 lbs.  Comes with tracking.  The limitation is 
size.  The envelopes and small box are under $6.  Where they can be a real 
bargain is if you need to mail something to Alaska or Hawaii.  Same price as 
across town.

$50 insurance is included, $200 is $3.30.

I doubt it ... there is not all that much room between the front

the need to reroute some of the cables with may not be possible if

Re: [Elecraft] KSYN3A (shipping)

[Doug Turnbull]

Dear OMs,
 I certainly see your point on shipping charges.   However the K3 is not
being made obsolete by a newer radio.If you have a single receiver the
price is pretty reasonable and if you have two radios what do we expect.
Elecraft makes money and I hope they continue to do so.

 The demise of R.L Drake was bad enough.The ham market is not that
lucrative and the likes of Wayne and Eric deserve their rewards.Then
these gentlemen never present themselves as anything other than brother
hams.  After all we are all members of the Loyal Order of Water Buffalo.

Re: [Elecraft] KSYN3A (shipping)

[Joe Subich, W4TV]

 Where they can be a real bargain is if you need to mail something to
 Alaska or Hawaii.

Actually, a Padded Flat Rate Envelope is a real bargain for many uses.
It's an 8 1/2 x 11 edge loading bubble pack envelope that will often
hold two or three 1 thick small boxes suitable for the K3SYNTH, PR6,
PR10, XG3, etc.  The envelopes are truly flat rate and will take
whatever you can stuff into them without regard to thickness, etc. as
long as the envelope remains intact.

The Padded Flat Rate Envelope is much more flexible than the
traditional document or the Legal Flat Rate envelopes.

If you want to save on the shipping, Just bunch up your orders.
Order 3 filters at a time instead of one at a time.

Elecraft has even combined my orders before to save my shipping cost.
Then need to change the line from Shipping to Shipping and Handling
The items do not Pack Themselves and the box does not address it's selfThey

Re: [Elecraft] KSYN3A FAQ

[Eric NO3M]

What is the passband of the filtering engaged in the KBPF3 when 
operating at 630M?  The concern at this band in many locations is BCB 
intermod, and generally an LPF is used in the RX chain.  Is it not of 
concern based on on-air tests, perhaps KBPF3 is on the table for an 
upgrade, or an outbound LPF recommended?

A:  With preamp OFF, we measured about -125 dBm at 475 kHz and -90 dBm at 250 
kHz. We have not measured MDS below 250 kHz, but the receiver will gradually 
become less sensitive as you go lower in frequency due to band-pass filter 
rolloff (in the KBPF3, which is required for operation below 160 meters). These 
tests were made with the signal routed through the RX ANT IN or XVTR IN jacks 
on the KXV3 option module. The preamp is not effective in this range and must 
be turned off. A sub receiver (KRX3) fitted with a KBPF3 should have similar 
performance, whether the signal is obtained from the main path (KXV3) or from 
the sub's AUX RF input.

Yes. While I've seen statements (I hate the word claim in this kind of

not seen ARRL measurements to confirm that.  I suspect that part of that

Re: [Elecraft] KSYN3A FAQ

[Wayne Burdick]

The KBPF3's lowest-frequency filter has a nominal passband of 0.5-2 MHz. The 
rolloff is not particularly steep, but this is the reason that the MDS at 250 
kHz is -90 dBm, while it's -125 dBm at 450 kHz.

Intermod should rarely be a factor because of the K3's very robust front end.

Those living practically on top of an AM broadcast station typically have been 
through this drill already and have notch filters. If not, we can design one 
for you (you get to build it, though :)

Re: [Elecraft] KSYN3A FAQ

[Wayne Burdick]

Another interesting issue regarding the Flex 6xxx series (and radios with a 
similar direct-digital-sampling RF architecture) is that A/D Limit descriptor 
in the blocking dynamic range column in Sherwood's chart. An ADC limit is a 
hard one; it does not gracefully soft-limit in the presence of strong signals, 
like an amplifier stage. Multiple signals in the passband can cause additive 
peaks that hit this ADC limit sooner, causing ghost signals (IMD) to appear. 
3-tone (or higher) testing may be needed to quantify the effect of the ADC 
limit in DDC receivers. Perhaps A/D Limit can then be converted into a useful 
number.

 Consider yourself lucky.  In my real world, it's an IC-746 and legal
 limit amp 0.65 miles away!
 
 Yes. While I've seen statements (I hate the word claim in this kind
 of sentence, since it implies that the person making the statement is
 a liar) that the latest Flex series radios are as clean or cleaner,
 I've not seen ARRL measurements to confirm that.
 
 No, but one can infer that from the Receiver data published by Sherwood
 on the Flex 6700 (receive LO Noise = 145 dBc/Hz).  Given the design of
 those radios the phase noise is generally clock jitter and would be
 reciprocal in transmit.
