Not necessarily -- it depends on the design. Some rigs have low phase 
noise on RX but not on TX.

REPLY:

Even with the computer turned off and the P3 also off, the problem is
still there. In fact it is getting worse. I tried it just now and even
when turning the VFO knob slowly, the frequency display is mostly
frozen, just moving a little intermittently.

There is nothing else connected to the K3.

Re: [Elecraft] Update to KSYN3A

My interest in this update is a reduction in interference in an SO2R
environment with two K3s. 

 

What is the conventional wisdom regarding the potential improvement in this
particular area?

[Elecraft] KIO3 problem

[Bob Towers]

I fired my K3 up in preparation for CQWW RRTY this weekend. I run MixW.

When I checked the CAT operation, it wouldn't work properly ie gave me 
some monsensical frequency readings in MixW's log. I thought it may have 
been a new motherboard in my PC, but checked the operation with my K2 
and it worked fine. The settings of the K3 are:


RS232 38499 b
KIO3 nor

MixW's settings are 38400 8 N 1, unchanged from the last time I used the 
rig.

COM 1 on the PC motherboard is set to 38400 8 N 1.

I tried a PCie dual serial port card in the PC motherboard - same problem.

I turned the baud rate down to 19200 in the K3, MixW and on the PC 
motherboard and all now seems to work as it should. I can live with 
that. But the question remains: is the KIO3 board becoming faulty?

The noise that we hear on transmitted signals, or through reciprocal
mixing in our receivers, is always the COMPOSITE noise - the vector sum
of both the Phase Noise and the Amplitude-Modulated noise. 

Most modern test equipment measures exclusively phase noise, so that's
what the equipment reviews quote as well. Then the advertisers jumped on
the bandwagon so now it's "Phase noise, phase noise, everybody's talkin'
'bout phase noise!" We are carelessly sliding towards labeling every
kind of noise as "phase noise" when very often it isn't. 

Don't ever forget that AM noise component. At some frequencies AM noise
can be even more important than the phase noise.  

If the transmit and receive paths use the same frequency-determining
signals (oscillators) then the phase noise - true phase noise, that is -
in the TX and RX paths should be very similar. Generically they should
be the same, so you'd need to identify some quite specific reasons for
PN to be different between TX and RX in any particular transceiver.

But a transceiver also contains many, many sources of AM noise - not so
much in the oscillators but in the TX and RX signal pathways. Because
those pathways are different, the levels of AM noise generically *do*
differ between TX and RX. 

Therefore we should always expect the *composite* noise to be different
between TX and RX - and that will probably be mostly because of
different AM noise levels.

Problems with AM noise on transmit are often made worse by designers
forgetting that the problem even exists. In older analog rigs, for
example, there may be significant AM noise on transmit because the TX
chain starts out at too low a signal level, and the designer forgot to
use low-noise techniques in that weak spot. 

In modern digital rigs, the analog TX signal comes from a DAC (Digital
to Analog Converter) which is heavily laden with AM digital noise that
needs careful filtering. There is an awful example in SM5BSZ's 2013
article on 'Band Pollution by Amateur Transmitters'
.   Figure 8 shows a very high
noise level at the output of the DAC (enough to make the sine-wave look
like a fuzzy caterpillar). Then that noise is insufficiently filtered,
leaving serious TX noise sidebands of only -75dBc at +/- 300kHz. Because
this is almost entirely AM noise, any test that focuses exclusively on
phase noise will miss it... and that particular manufacturer did miss
it.

In contrast, the K3 came top of the table for suppression of wideband TX
noise (Table 1, which pre-dates the KX3).

[Elecraft] K3EXREF upgrade

[George Dubovsky]

With all of this talk of synthesizer upgrades, if you are considering
adding a K3EXREF while your K3 is open, this is a shameless plug for a very
nice Trimble Thunderbolt 10 MHz precision source plug-and-play "appliance"
that I have posted on QTH. Thank you.

Re: [Elecraft] KSYN3A

[Gary Smith]

I second this. 

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.

[Elecraft] KSYN3A - installation question

[Dauer, Edward]

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 R&R is required?  Message below says it is.

If the sub does have to be R&R¹d, anyone have suggestions about how to
reinstall it without the major fuss I experienced?

I also suggest that everyone should consider the other shipping options

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

It pays to look at all the options.

[Elecraft] Remote Access to P3

[Paul Christensen]

I am looking at ways to bring back P3 panadapter information over the Internet. 
 Programs like VNC, Teamviewer, etc. appear to limit screen refresh to about 
once per second.  That results in a very "choppy" display that's almost 
useless.

Is there a means to bring back near-real-time P3 screen information over the 
Internet?  Since the output of the P3SVGA is designed to feed a video monitor, 
perhaps we could use a device that converts the P3SVGA output into a format 
suitable for streaming.  

Anyone know of such a device that's also bandwidth conscious over an Internet 
connection?

Paul, W9AC

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.

Even with the computer turned off and the P3 also off, the problem is

when turning the VFO knob slowly, the frequency display is mostly

There is nothing else connected to the K3.

[Elecraft] KX3 VFO leakage on antenna

[w...@msn.com]

Is anyone else experiencing leakage from the VFO via the antenna?
I had my FT-2000 on and could hear the KX3 VFO as I tuned near the KX3 
operating frequency on the FT-2000.  They were on separate antennas 
about 40 feet apart.  Varying the KX3 tuning knob varied the signal on 
the FT-2000.

Re: [Elecraft] VFO problem

[Matt Zilmer]

I would suggest it's worth the time to swap the VFO A and VFO B
encoder boards.  It could be the encoder itself or its contacts to the
front panel board, either of them.

If you take this course, you might want to check the encoder board
contacts on each of them, and also take a look at the contacts on the
front panel board.  There may be some corrosion, dust, etc. on the
contacts.

[Elecraft] FW Beta 5.10

[Jim's Desktop]

Just got around to installing 5.10.  Good thing I remembered Wayne's 
caveat to re-run the power calibration routines in the K3 Utility as I 
have a tendency to forge ahead without reading the "release notes" that 
carefully.


I had been having a few minor power output glitches when running the 
KPA500 amp, and the re-run of the 50 watt power out cleared those 
glitches up nicely.  Probably the newer FW had somewhat to do with it 
also.


I'd been putting the upgrade off as everything was working well enough 
for my operating style until I recently ordered the KSYN3A modules and I 
realized the latest FW rev I had was 5.01 so I figured I'd better 
upgrade to 5.10 at least.


Looking forward to the arrival of the new synthesizers, especially with 
the faster QSK switch times so I won't have to lose SPLIT when sending 
QRQ (my version of QRQ is only around 45 wpm as with my Tinnitus 
everything blurs beyond 45).  I used to be able to run 60+ and there is 
one guy (will remain nameless) who always calls me at 60+ when I call CQ 
and refuses to slow down to where I can copy him.  He seems to think 
he's helping me get faster but that's medically impossible now.

Re: [Elecraft] Remote Access to P3

[Paul Christensen]

Just compared Real VNC with TeamViewer (TV) over local LAN.  (TV) is faster 
and pretty much usable.  Not so for Real VNC.


Looks like the AverMedia Broadcaster video capture card (per Tom's input) is 
the best option although for the price, I'm not sure value is there.  I can 
see why some folks are opting for simple web cams.  The reality is that 
options are definitely limited.


Thanks to all for the feedback.

Is there a means to bring back near-real-time P3 screen information over 
the Internet? Since the output of the P3SVGA is designed to feed a video

into a format suitable for streaming.


Anyone know of such a device that's also bandwidth conscious over an

Re: [Elecraft] VFO problem

I think you are on to something, Matt.  On a hunch, I performed a
"percussive reset" as NASA calls it. I lifted the front on the K3
about an inch and dropped it. The problem went away for now. When it
comes back, I will do as you suggest. 

Many thanks to all who replied.

Re: [Elecraft] VFO problem

[Matt Zilmer]

Percussive resets are well-known for finding a general problem area.
They don't localize it, but it's a start.

Good luck with this.  An encoder board "SOL" problem happened to me
about five years ago, and I followed the same advice I gave you (which
came from someone else).  :}

Re: [Elecraft] VFO problem

[David Christ]

This was a standard technique used by TV repairmen back in the days of tube 
consoles and house calls.  For intermittent problems one waited until the owner 
left the room then lifted up one side about 6 inches and let it drop.  Usually 
either fixed the problem or caused a hard fault that could be troubleshot.  Now 
the owner just buys a new TV.

Re: [Elecraft] Remote Access to P3

[Paul Christensen]

Had a thought - I already own an SDR-IQ with SpecrtaVue software.  Tried it 
with TeamViewer and it works well.  No expensive video capture card needed.


SpectraVue has basic point and click frequency change.  Options are not 
quite as integrated when compared to the P3, but perfectly adequate for our 
remote station.

[Elecraft] looking for old style sub-receiver, maybe...

Since I was going to add the sub rcvr to my K3 SN 8760 kit (now building)
later this year,
it occurs to me I might want to expedite purchase of new or old.

RSVP off list if you have and old style sub ready to sell and we'll talk.
I will have to work out how that might affect warranty, though.

to continuously power cycle as long as the K3 is transmitting.  Generally this 
only occurs when driving my KPA500 amp beyond a certain output level which 
differs for a given band and frequency.  I am powering the KAT500 with its own 
AC adapter.  The problem can occur in both bypass and auto mode.

7-10 ferrite beads on the coax attached to the KAT500 solved the power cycling 
problem for my hex beam antenna and I successfully operate QRO in bypass mode 
on all bands and modes.  However the beads did not help with the wire vertical. 
 I can drive 300w into my dummy load with no ferrite beads on the coax and the 
KAT500 is fine.

The SWR is low enough I should be able to use these antennas to run the KAT500 
in bypass mode.  If I put it in Auto mode the problem is exacerbated.  I can 
tune the wire vertical just fine with the KAT500 in Auto mode at a tuning level 
of 25w from the K3.  However, if I try to transmit at 5w or more (SSB for 
example), the KAT500 starts to power cycle.

I have no problem using the wire vertical if it is connected directly to the 
K3's internal ATU.  I observed that in this configuration, I could still trip 
the power on the KAT500 even though it's not even connected to that antenna, so 
I do believe this may be a common mode RF issue in the shack.  Somehow noise is 
finding its way into the KAT500.  Several turns of the AC power adapter's cord 
around a few ferrite beads hasn't helped either.

I will at some point remove the KAT500 from the equation and see how things 
work by directly connecting the K3 to the KPA500.  I would like to keep it in 
service as I might need it at the extreme band edges of the wire vertical.   

The vertical wire is from W8AMZ.  I don't believe there is any kind of current 
Balun inside the feed point but I did place 10 ferrite beads over the coax at 
the feed point.  I'm running 100' of RG8X to this antenna.  The hex beam 
antenna is feed with LMR-400 and RG-213.

So I don't know if the problem is specific to my vertical wire antenna and 
feedline or if I should suspect a defective KAT500.

Before I take the KAT500 offline, can anyone suggest some further experiments 
to try?

Yes. The problem is that ferrite beads slipped onto a transmission line 
does NOT make an effective common mode choke. Those beads are inductive, 
and, depending on the length of the line and the operating frequency, 
many lines look capacitive. The inductance resonates with the 
capacitance, and the common mode current increases.


To be effective as a common mode choke, we need a high value of common 
mode impedance, and the best way to get there is with a high value of 
RESISTANCE. We obtain that by forming a low-Q parallel resonant circuit 
-- we wind multiple turns of the feedline through a lossy ferrite toroid 
or clamp-on. The number of turns needed depends on the ferrite material 
and the operating frequency. The best ferrite material for the HF bands 
is Fair-Rite #31, because it has the lowest effective Q over the widest 
frequency range.

Re: [Elecraft] My KAT500 seems very sensitive to common mode RFI

[Vic Rosenthal 4X6GP/K2VCO]

Don't know what kind of ferrite beads you are using, but many are 
intended for VHF use and are not helpful at HF. Also, it is usually 
ineffective to just put a bead on the coax -- you should wrap multiple 
turns through a large toroid. Good ferrite materials for HF are #31 for 
1.8-7 mHz and #43 for 14-30 mHz. Either one would probably work fine for 
both antennas.

Re: [Elecraft] VFO problem

My father, W1BML used to repair TVs and radios after his work was

electronics repaired (was W8QXF & then W3QXF when the area changed). 

I remember going with him on a house call and the unplugged TV was 
the problem. He wouldn't charge her & told me on the way home it was 
good PR & why that was worth more than the money that house call 
would be. He never lacked for business.

Re: [Elecraft] My KAT500 seems very sensitive to common mode RFI

[Jeff Hall]

Thanks Jim, I'll give it a read and order up some mix-31 toroids.  Does it 
surprise you the KAT500 is getting power cycled as I described?  Is it really 
that sensitive? 10 of the ferrite beads I got from DXStore (rated for 150MHz or 
lower) work fine for 10m-20m. But no dice on 40m, so I guess the frequency is 
just too low for them to be effective (or perhaps I'd need like 50 of the 
suckers!)

No Elecraft replacement for ... I plan to look carefully at the FT-991
tomorrow (Orlando Hamcation) as it seems to cover all the bases except for
1.2 GHz.  It would give me an excuse to replace both my token Yaesu

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.

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 R&R is required?  Message below says it is.

If the sub does have to be R&R¹d, anyone have suggestions about how to
reinstall it without the major fuss I experienced?

Re: [Elecraft] KX3 VFO leakage on antenna

[David Orman]

Glad this thread popped up, noticed this earlier when out portable with a
friend (or rather, he noticed it); this setting fixed it entirely. I'll
keep it off unless needed as the manual seems to indicate that's the right
way to go.

Thank you,

Re: [Elecraft] KSYN3A (shipping)

[David Christ]

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.

[Elecraft] Split

[Mike Harris]

Hi,

Occasionally DXpeds lose their split setting which causes chaos when 
running a pile. The usual comment is it's a K3 thing.  The question is 
why is it?


I use Logger32 and when I click on a spot whilst in split mode, the K3 
QSYs and split is cancelled.


At first I thought it was because that Config: SPLT SV was NO so I 
changed it to YES but this didn't make any difference.  Certainly I 
could change band and return and split was indeed saved.


Next I put the K3 in split and then entered a frequency in the same band 
in the L32 log entry window, the K3 QSYed and split cancelled.


Next restored split and entered a frequency from the K3 keypad, split 
stayed on.


OK, looked at what was happening on the com port serving the K3.  When 
L32 sends the frequency to the K3 it prefixes it with FR0 which 
according to the programmers reference cancels split mode.  So the 
response of the K3 was to be expected.  A typical example is:


Set Radio Freq/Mode: FR0;0001816;MD2;FA001816;

No idea what other software does in these circumstances.  However, if 
popular DXped software, N1MM or the like does something similar it will 
be easy for a DXped operator to unknowingly and unnoticed cancel split 
and go walkabout whilst tuning the pileup.


Clearly FR0 is a useful command, I use it in an RTTY macro to cancel 
split.  I guess that the L32 development team assume that if you enter a 
QSY you intend to come out of split so include the FR0, reasonable I 
guess for a home operation.  Users of alternative applications might 
wish to conduct the same tests.


The simple answer is better cockpit drill by the DXped operator.  But 
even having set up the correct band/mode/filter/antenna etc it is still 
easy to accidentally cancel split under pressure, it's a K3 thing, is it?


Have I missed something?

Your thoughts please gentlemen,

Mike VP8NO

Re: [Elecraft] KX3 VFO leakage on antenna

[Walter Underwood]

The RX ISO preamp draws a bit more current than the regular preamp, so it 
defaults to off to preserve battery life. As far as I know, that is the only 
negative.

KX3 models after the mid-2000 serial numbers also have a filter on the BNC to 
knock down some leakage in the VHF range. Mine has it — the tiniest toroid I’ve 
ever seen. Details about that upgrade for older KX3’s are here:

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.

No, it's a programmer thing ... the same thing happens with Yaesu (new)

command with those rigs as well.

QSY you intend to come out of split so include the FR0, reasonable I
guess for a home operation.  Users of alternative applications might
wish to conduct the same tests.

The simple answer is better cockpit drill by the DXped operator.  But
even having set up the correct band/mode/filter/antenna etc it is still
easy to accidentally cancel split under pressure, it's a K3 thing, is it?

Have I missed something?

Your thoughts please gentlemen,

Mike VP8NO

Re: [Elecraft] KSYN3A (shipping)

If you are shipping short distances (next state or two), the Regional 
Rate method
is even cheaper. I sent a Medium size box from Tucson to San Diego for 
under $6.

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

Re: [Elecraft] Update to KSYN3A FAQ (some measured dynamic range numbers)

[Chortek Bob via Elecraft]

Hi Johhny,
I'll probably get flamed for saying this, or someone more knowledgeable that I 
will point out how ignorant I am, but here is my layperson's understanding of 
this issue:
Assuming a MDS of -128 dbm, and an S9 signal equivalent to -73 dbm, IMD will 
begin to be a problem when two out of passband signals combine as follows:
IMDDR      Signal causing IMD = Noise Floor
55 db    S960 db    S9 plus 5 db65 db    S9 plus 10 db70 db    S9 plus 15 db75 
db    S9 plus 20 db80 db    S9 plus 25 db85 db    S9 plus 30 db90 db    S9 plus 
35 db95 db    S9 plus 40 db100 db    S9 plus 45 db105 db    S9 plus 50 db
You can see that if your rig has an IMDDR of 90 db, it would take a signal S9 + 
35 db before you would likely notice any adverse affects from IMD caused by two 
out of passband signals (at the required spacing).
So, a person who has a rig with an IMDDR of say 95 db would only notice an 
improvement in the IMDDR when they are exposed to two out of band signals 
causing an IMD product when those signals are more than S9 plus 40 db.  The 
question you need to ask yourself is, how often are you faced with that 
situation?  The constant pursuit for improved IMD performance, it seems to me, 
is a worthy goal, but whether it benefits a particlar amature operator depends 
on whether he or she is faced with two out of passband signals that combine 
with the spacing required to cause an IMD product in his or her rig, AND the 
number of times those signals are sufficiently strong to exceed the IMDDR of 
their rig.  For some contestants, this is a BIG factor, but for other folks it 
rarely matters. It all depends on your operating environment

I'm am sure this is not 100 correct, as I am not an engineer, but you should 
get the general idea

Hi all,

I've updated the KSYN3A FAQ with the following information regarding testing of 
a K3 with the new synthesizer performed by Rob Sherwood, NC0B.

* * *

Q: What is the approximate 2-kHz dynamic range (IMDDR3) of the K3 when using 
the new synthesizer?

A: Our tests show in excess of 105 dB with the narrowest filters, though there 
are many factors, and this should be considered approximate. (A very robust 
test setup is required to make these measurements.) Rob Sherwood tested a K3 
with a KSYN3A and obtained the following results:

    2-kHz IMDDR3 with 200-Hz roofing and DSP filter = 106 dB
    2-kHz IMDDR3 with 400-Hz roofing and DSP filter = 103 dB

Rob will be posting this information in his receiver performance chart 
(http://www.sherweng.com/table.html) after he completes his full suite of tests.

* * *

The above numbers were used with Rob's permission.

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 :)

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] Shipping and Handling

[Chuck Smallhouse]

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.

73, Tony K4QE


I consider that all who offer items to sale direct, and usually over 
the Internet, have already included the cost of the order 
processing/paperwork and the packaging.  You are not going to pick it 
up over the counter !  Otherwise I tend to consider the excessive P & 
H charges, as a form of 'bait and switch'.


Transportation costs from the dealer to the shipping facility, should 
not be considered, as all now offer direct pickup, even USPS.  I feel 
that it's only right for the shipper to offer their customers the 
most inexpensive method available, to the recipient's location.


I live in a semi-rural area and the local (35 miles away) brick and 
mortar stores, are always complaining about the unfair competition 
from the "mail order" business and how they should collect state sales taxes.


The savings that I realize in both $ and environmental costs, in not 
making that 70 mile round trip, can be enormous .  Generally the 
shipping costs are in the same neighborhood, as that of the sales tax 
I don't have to pay.  Although there are some that offer free 
shipping (no handling) above a certain sales amount.


Amazon has chosen not to fight our AZ State Tax Commission and are 
now charging (they only have a distribution center here) state sales 
tax on their orders, plus shipping costs.  I no longer am a customer 
of theirs !


For my own 'out' shipping, I either have to go 30 miles to an 
overpriced franchised UPS shipping center (the main UPS center is 50 
miles distant) or use my very friendly and helpful village PO and the 
USPS.  I'm glad to, as they need the business and  I've never 
experienced a better one !


Chuck,  W7CS

Re: [Elecraft] VFO problem

[Edward R Cole]

Reminds me of a similar service call for a TV satellite system that 
"totally would not work".  I was not smart enough to suggest looking 
at the ac cord so I drove the 120-miles and of course first thing I 
checked was power..."and the ac cord was unplugged".  Boy were my 
customers embarrassed.  They offered to pay my service call but I 
could not do that.  We settled for gas money ($1.50/gal back then).


Rules for troubleshooting: what are the symptoms (what is not 
working), check power inputs; check configurations (settings); 
look-feel-sniff; measure for required output - then get out the 
manual/schematic/tools.  An "old" tech once advised me that most 
problems were simple ones - so do not go off looking for complicated 
one's before doing simple tests.  (that drop test works)  Use of 
freeze-spray does the same thing.  So does wiggling and probing.

Re: [Elecraft] KAT500 - Auto Bypass for Non Ham Bands?

[Dick Dievendorff]

It depends on how the ATU learns about the frequency.

If you have your K3 connected to your KAT500 and the K3 provides frequency
information without transmitting, then the KAT500 can change ATU settings in
mode MAN on K3 QSY, without transmitting.   (This uses a 15-pin ACC cable
between the K3 and KAT500 and the K3 configuration menu for KAT3 is set for
"KAT500y" by pressing the 1 button the right number of times).

Otherwise the KAT500 senses Tx frequency, and presumably you won't want to
transmit outside the ham band for the KAT500 to learn the frequency  by
counting the Tx frequency.

The KAT500 Utility Operate page has the ability to store an arbitrary tuner
setting (including "bypassed") at the then-current frequency.

I just tuned my K3 to 14500 and on the KAT500 operate page I checked
"bypass" in the "others" group , just to the left of the "tune" button. Then
I clicked "memorize", and the utility stored a "bypassed" tuning solution in
the memory for 14496 kHz.  When you tune around, the ATU loads settings from
the nearest non-empty memory. When I qsy to 14350, the ATU loads my
not-bypassed settings for the high end of 20.  When I qsy to 14425, the ATU
changes to "bypassed" because the nearest memory (14500) had a tuning
solution of "bypassed".  The operate page shows the frequency the KAT500 is
aware of. If it's moving around as you QSY with the K3, then you have the
needed information.

The ATU provides memories for all frequencies between 1.5 and 60 MHz.

REPLY:

The best TV tech I ever knew (and I knew a lot) gave me the best
advice I ever got about troubleshooting:  "Forget your meters and
generators and stuff. The best troubleshooting tools you have are you
own two eyes."  

There were times I did not follow his advice, to my regret. I would
waste time with scope and meter and when I finally found the problem,
it was obvious if I had just looked carefully first. 

Joe Tolemeo was his name, probably RIP now, but the best ever. 

Thanks, Joe.

Re: [Elecraft] VFO problem

[David Christ]

’Tis true that doing a reset can cause a problem to go away and is often the 
only way out — but a reset should not be the first remedy tried.  When I was 
part of a network group responsible for a nationwide data/voice network we had 
a co-worker that drove us nuts.  His solution to any problem was to immediately 
go around and rest everything.  Kept us from collecting information about 
device status when the fault occurred.  Maybe got things up again but did 
nothing for preventing the next fault.  So before you push that reset, gather 
what information you can to help determine the root cause.

Re: [Elecraft] My KAT500 seems very sensitive to common mode RFI

[Harry Yingst via Elecraft]

There must be something special about 40 meters and micro-controllers.
My Aquarium Controller used to do a Reset when I transmitted on 40.The cure for 
me was to wrap the control cable leads through Some Snap on chokes
I just installed my KAT500 today and considered taking thepower lead and 
wrapping it around a snap on choke a few times.

 Subject: [Elecraft] My KAT500 seems very sensitive to common mode RFI
   
I have a Hex Beam and a 40m wire vertical w/ two elevated radials.  I have been 
fighting what appears to be a common mode RFI problem which causes the KAT500 
to continuously power cycle as long as the K3 is transmitting.  Generally this 
only occurs when driving my KPA500 amp beyond a certain output level which 
differs for a given band and frequency.  I am powering the KAT500 with its own 
AC adapter.  The problem can occur in both bypass and auto mode.

7-10 ferrite beads on the coax attached to the KAT500 solved the power cycling 
problem for my hex beam antenna and I successfully operate QRO in bypass mode 
on all bands and modes.  However the beads did not help with the wire vertical. 
 I can drive 300w into my dummy load with no ferrite beads on the coax and the 
KAT500 is fine.

The SWR is low enough I should be able to use these antennas to run the KAT500 
in bypass mode.  If I put it in Auto mode the problem is exacerbated.  I can 
tune the wire vertical just fine with the KAT500 in Auto mode at a tuning level 
of 25w from the K3.  However, if I try to transmit at 5w or more (SSB for 
example), the KAT500 starts to power cycle.

I have no problem using the wire vertical if it is connected directly to the 
K3's internal ATU.  I observed that in this configuration, I could still trip 
the power on the KAT500 even though it's not even connected to that antenna, so 
I do believe this may be a common mode RF issue in the shack.  Somehow noise is 
finding its way into the KAT500.  Several turns of the AC power adapter's cord 
around a few ferrite beads hasn't helped either.

I will at some point remove the KAT500 from the equation and see how things 
work by directly connecting the K3 to the KPA500.  I would like to keep it in 
service as I might need it at the extreme band edges of the wire vertical.  

The vertical wire is from W8AMZ.  I don't believe there is any kind of current 
Balun inside the feed point but I did place 10 ferrite beads over the coax at 
the feed point.  I'm running 100' of RG8X to this antenna.  The hex beam 
antenna is feed with LMR-400 and RG-213.

So I don't know if the problem is specific to my vertical wire antenna and 
feedline or if I should suspect a defective KAT500.

Before I take the KAT500 offline, can anyone suggest some further experiments 
to try?

73, Jeff W6UX

Re: [Elecraft] My KAT500 seems very sensitive to common mode RFI

[Michael Walker]

There are some great articles on common mode chokes

http://www.yccc.org/Articles/W1HIS/CommonModeChokesW1HIS2006Apr06.pdf

The other is K9YC's cookbook.

Since I bought a VNA, I have been able to play with the choking value of
some random chokes.  Very interesting.

Re: [Elecraft] KAT500 - Auto Bypass for Non Ham Bands?

[Harry Yingst via Elecraft]

I have the KAT500 hooked up with the AUX cable (15 pin cable).
I went to 25 MHZ and selected ant 1 and bypass and saved it with the 
utility.Upon returning to 25 MHz it's still in tune and on ANT2 (Preferred for 
that band).
The solution is probably a Feature Request to have the SW bands added for those 
of us with the KBPF3

[Elecraft] Beta 5r10

[Mike Harris]

G'day,

Just installed Beta 5r10.  What a dreadful shame that the Dual PB 
"context/focus" mode has been done away with.  I used it a lot whilst 
tuning up the band S&P handing out points in CW contests.  Nice and 
smooth, easy listening, gently alerting you to the next signal in line. 
 The APF sounds ghastly, always seemingly on the edge of  ringing.


Backwards step, sorry.

Regards,

Mike VP8NO

It also took the VFO link away from the buttons. I use it all the time while 
alternating between pileup busting and normal tuning around,  Fortunately I 
have that function programmed in an external button box.  No spare K3 
programmable buttons available.

Re: [Elecraft] KSYN3A (shipping)

[Harry Yingst via Elecraft]

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 
have to pay someone to do that labor.

I learned years ago that there is something special about 40 meter RF.  I've
gotten into more "stuff" when on 40 meters than anything else since 21 MHz TV
IFs went away.  I've melted things in radios while barefoot too.  I don't know
what it is, but lots of things seem to be sensitive to that band.

Thanks everyone for their replies to my problem.  I read Jim Brown's paper this 
afternoon and have ordered some mix 31 Big Clamps.  I'll try putting one at 
each end of the 40m coax feedline (RG8X) with the prescribed number of turns.

I have a Hex Beam and a 40m wire vertical w/ two elevated radials.  I have been 
fighting what appears to be a common mode RFI problem which causes the KAT500 
to continuously power cycle as long as the K3 is transmitting.  Generally this 
only occurs when driving my KPA500 amp beyond a certain output level which 
differs for a given band and frequency.  I am powering the KAT500 with its own 
AC adapter.  The problem can occur in both bypass and auto mode.

7-10 ferrite beads on the coax attached to the KAT500 solved the power cycling 
problem for my hex beam antenna and I successfully operate QRO in bypass mode 
on all bands and modes.  However the beads did not help with the wire vertical. 
 I can drive 300w into my dummy load with no ferrite beads on the coax and the 
KAT500 is fine.

The SWR is low enough I should be able to use these antennas to run the KAT500 
in bypass mode.  If I put it in Auto mode the problem is exacerbated.  I can 
tune the wire vertical just fine with the KAT500 in Auto mode at a tuning level 
of 25w from the K3.  However, if I try to transmit at 5w or more (SSB for 
example), the KAT500 starts to power cycle.

I have no problem using the wire vertical if it is connected directly to the 
K3's internal ATU.  I observed that in this configuration, I could still trip 
the power on the KAT500 even though it's not even connected to that antenna, so 
I do believe this may be a common mode RF issue in the shack.  Somehow noise is 
finding its way into the KAT500.  Several turns of the AC power adapter's cord 
around a few ferrite beads hasn't helped either.

I will at some point remove the KAT500 from the equation and see how things 
work by directly connecting the K3 to the KPA500.  I would like to keep it in 
service as I might need it at the extreme band edges of the wire vertical. 

The vertical wire is from W8AMZ.  I don't believe there is any kind of current 
Balun inside the feed point but I did place 10 ferrite beads over the coax at 
the feed point.  I'm running 100' of RG8X to this antenna.  The hex beam 
antenna is feed with LMR-400 and RG-213.

So I don't know if the problem is specific to my vertical wire antenna and 
feedline or if I should suspect a defective KAT500.

Before I take the KAT500 offline, can anyone suggest some further experiments 
to try?

[Elecraft] [K3] General coverage hijacks ham band

[d...@lightstream.net]

I am probably doing something wrong, but I cannot find any reference to
the following issue in the K3 manual.

It seems that if one tunes to a non-ham band (general coverage) frequency
(I used numerical direct frequency entry), the ham band closest to the
target frequency now assumes the targeted general coverage frequency.

For example, I was on 40m and wanted to check a local broadcast AM station
at 1100 KHz. I entered "1.100" via the "FREQ ENT" button, and the radio
tuned to 1100 KHz as expected. However, now when I cycle through the ham
bands, the 160 meter slot is set to 1.100 Mhz instead of 1.8XX MHz.

Is this the way it is supposed to work? It's a bit of a deterrent to use
the KBPF3 to explore general coverage frequencies if a ham band gets
hijacked as a result.

Re: [Elecraft] My KAT500 seems very sensitive to common mode RFI

[Jeff Hall]

I have several turns of the AC adapter cord through two snap on beads.   I 
don't have anything on the AUX cables at this time, but that is something I 
should probably check.   I ordered 6 of the Mix 31 Big Clamp toroids from KF7P. 
 For the 40m vertical I'll place one choke at the feedpoint and see if the 
problem is resolved.  If not, I'll place another choke at the KAT500.  If I 
still have a problem, another choke will be placed at the output of the KPA500. 
 If that still doesn't work, another choke will be placed at the output of the 
K3.  Once I have suppressed the common mode RF on the vertical, I'll try 
replacing the string of ferrite beads on my hex beam's coax with a Big Clamp 
choke at the KAT500.

Re: [Elecraft] [K3] General coverage hijacks ham band

[Matt Zilmer]

Hi Dale,

When you're tuning around outside the hand bands, your last "dwell"
frequency will be set in the appropriate ham band  For example,
listening to WWV on 15 MHz, 15.000 will become your VFO A's 20m
frequency.  That VFO A frequency will persist across a power off / on
cycle.  This behavior is consistent whether or not your K3 was last
left in the ham bands.

I don't know all the frequency limits for which non-ham frequency
ranges are assigned to which ham bands, but in terms of being
reasonable they make sense (imho).

If you combine SWL / general purpose and ham use, I'd suggest using
memories to keep your common-use frequencies in.  That way, when you
tap the M>V button and dial the memory in, you always get a known
frequency (either inside or out of the ham bands).  I use this method
for ham, SWL, and MARS operation and it does seem to work well.

Re: [Elecraft] *****POSSIBLE SPAM***** Re: [K3] General coverage hijacks ham band

[d...@lightstream.net]

Hi Matt,

Thanks for your response. I see that using the memories will tune to the
stored frequency -- but it still hijacks a ham band. I like using the
'Band' button on the KPA500 to band-select the K3, but after selecting a
non-ham band memory, that gets screwed up as well. I don't see a way to
access a G/C frequency without this being the result.

It seems to me that if the ham band slots disallowed frequency assignments
outside of their respective bands, that would keep this from happening,
and would be consistent with the K3 being first and foremost a ham-band
receiver.

Re: [Elecraft] Beta 5r10

[Guy Olinger K2AV]

One thing I like about it is that a "hold" on the SUB button now puts
you back in diversity immediately. Quick way to get it back when a
split spot has turned it off.

I still would like to see variable APF to let me set it a little
farther off ringing, or put a wider peak on some situations. Use the
RIT control to control APF bandwidth if RIT and XIT are off. That
other fast tune thing with the RIT knob winds up happening when I
forget it's on. Now I can't find the menu entry to turn it off.

I still would like to see variable APF to let me set it a little
farther off ringing, or put a wider peak on some situations. Use the
RIT control to control APF bandwidth if RIT and XIT are off. That
other fast tune thing with the RIT knob winds up happening when I
forget it's on. Now I can't find the menu entry to turn it off.

Mike (et al),

It's beta, experimental, subject to further revision. We took the original

LINK). APF, in contrast, has been hugely popular. But with this input, we'll 
reconsider.

Wayne,

Will this become non-beta (released) before the 
new synth cards arrive, or should we go ahead and 
install the beta now?

Re: [Elecraft] [K3] General coverage hijacks ham band

[Bill Frantz]

I suggest adding a "band" between each ham band. When switching 
away from these bands, the frequencies/modes/etc. would be saved 
in the band and the ones from the new band would be loaded as 
happens now.


These bands would not be accessed with the band up/down switch 
unless enabled using a new menu item, thus avoiding pollution of 
the ham bands with out-of-band frequencies.


One can dream further and have multiple bands between the ham 
bands for SW broadcast, public service etc. One could even 
imagine a WWV band which has all the WWV frequencies in a 
non-contiguous band. I don't really recommend any of these 
frills, but they are fun to think about.

Re: [Elecraft] My KAT500 seems very sensitive to common mode RFI

[Don Wilhelm]

Jeff and all,

I see many hams reporting placing common mode chokes on AC lines, DC 
lines, AUX cables and other lines in the shack.


I am of the opinion that the proper use of common mode chokes is on the 
antenna feedlines.  With coax fed antennas, a choke right at the 
feedpoint and with parallel line non-resonant antennas, at the point of 
transition from parallel line to coax.  You may not notice a problem at 
lower power, but if the power is increased to 500 watts (or to the legal 
limit), problems not apparent at lower power begin to 'raise their ugly 
heads'.


Chokes placed in the antenna system locations will reduce the amount of 
RF getting back into the shack and will reduce the need for chokes on 
the shack lines themselves.


Of course, if the antenna radiation is coming directly into the shack 
(such as from an antenna in close proximity to the shack), then you may 
still need additional chokes in the shack.


Those using offset center fed dipoles or end fed dipoles will have to 
take more extreme measures (use the K9YC common mode chokes at the 
antenna feedpoint and at the feedline entry point to the shack).  Those 
antennas are 'infamous' for creating 'RF in the Shack'.  It may not be a 
problem at 100 watts, but the problem grows exponentially as the power 
is increased.

 For the 40m vertical I'll place one choke at the feedpoint and see if the 
problem is resolved.  If not, I'll place another choke at the KAT500.  If I 
still have a problem, another choke will be placed at the output of the KPA500. 
 If that still doesn't work, another choke will be placed at the output of the 
K3.  Once I have suppressed the common mode RF on the vertical, I'll try 
replacing the string of ferrite beads on my hex beam's coax with a Big Clamp 
choke at the KAT500.

Re: [Elecraft] *****POSSIBLE SPAM***** Re: [K3] General coverage hijacks ham band

[Scott Manthe]

I solve this problem by entering a ham frequency after listening to a 
general coverage frequency.


It takes about 2 seconds to do and solves the problem completely. So, 
after I'm done listening to AM720, I simply enter 1.8mhz on that VFO and 
all is well.

Hi Matt,

Thanks for your response. I see that using the memories will tune to the

'Band' button on the KPA500 to band-select the K3, but after selecting a
non-ham band memory, that gets screwed up as well. I don't see a way to
access a G/C frequency without this being the result.

It seems to me that if the ham band slots disallowed frequency assignments
outside of their respective bands, that would keep this from happening,
and would be consistent with the K3 being first and foremost a ham-band
receiver.

Re: [Elecraft] *****POSSIBLE SPAM***** Re: [K3] General coverage hijacks ham band

[Matt Zilmer]

Hi again Dale,

I'm not taking a position, just reporting how the K3 works now.  Maybe
that was obvious, maybe not.

With many Amateur transceivers that allow receive outside the ham
bands, the VFO always initializes to the last frequency dialed in. The
only non-Elecraft example I have here is an old 1996-era JRC-245, but
I've observed that same behavior with many others.  The K3 is
consistent in its behavior with most other transceivers.

>From what you've written, it looks like the BAND up/down control is
really the problem.  This is the reason I used (to myself) for the M>V
switch and using memories to control initial ham band entry after
tuning around outside.  I do a lot of this, being a Curious George
type, and also a MARS op and doing occasional SWLing.

Being objective, I've thought up a few corner cases.  For whatever
reason, I've become pretty good at this lately.  Try these on:

1. The op dials past the ham band edge into g/c territory.  In this
case, make the band edge persistent?  I'm not sure that would be
correct.  Most ops do not operate near the band edges.  Maybe I'm just
biased in this way.

2. The last direct frequency entry was 15.000 MHz.  Would you preserve
the previous direct frequency entry that was inside the Amateur 20m
band?  Or the last VFO A frequency?  Or something else (I'm trying to
use a little imagination, not something I'm great at).

3. This one would probably work for you.  The op dials into the ham
band from g/c territory.  I'm pretty sure that what most ops would
want to persist on VFO A is this last dwell frequency.  That would
also be consistent with most transceivers' behavior, and what many ops
would expect.

4. For MARS operators, SWLers, and other legitimate ops  that
habitually operate outside the ham bands, their K3s would constantly
revert to a previous dwell frequency, but only one from inside the
nearest ham band (hm, the one to which that dwell frequency range is
assigned).  I think this would tick off the ops wanting to preserve
the last frequency dialed or keyed in.

I guess it's a conundrum, or a bit of one at least.  From memory, I
think there was a Field Tester discussion on this topic long ago. This
and some hard decisions on the part of Elecraft gave the K3 its
present behavior.  

Hey - at least the K3's behavior in this regard is 100% consistent! 

 :)
