Tnx Lyle for the info. I am not saying this is a bug, but it would be nice
if the KDVR wasn't interrupted if you break VOX while it is transmitting.
You can talk to someone else in the shack while the recorded message is
playing. Kind of got spoiled using the recorder in N1MM which doesn't
interrupt the playback of a recorded message unless you hit ESC.
Using the KDVR is a simpler hookup with programming the F1-F4 keys in N1MM
rather than using the pc's audio card and less chance of feedback, hum and
other potential issues.

Yes.

The DVR is after MIC GAIN and before filtering/processing, so it records 
based on the mic gain setting, and plays back to the system at that same 
exact level.

Lyle KK7P

 ...In other words, changing the MIC gain during playback
 does NOT affect then playback level.  However, the DVR evidently stores
 UNCOMPRESSED audio because the compression DOES vary directly with the
COMP
 control during DVR playback.  Again, is this normal/expected?

[Elecraft] K3 APF

Finally had some time to play with the APF. This morning VK6HD was called
out on Topband. I could not hear him at all. I have limited real estate so
no long beverages. Just have some pennants and flags for receive. Tuned to
where the pileup was at. Turned on the APF and he pops right out of the
noise. Listened to him for about a ½ hour trying different settings  RF
Gain, Width, Preamp both internal and external. I forgot to try the NR. Just
amazed the one thing that made the difference comparing the other parameters
was the APF. 

I just need to remember to HOLD the XFIL button and not TAP it to toggle the
APF.

 

Tnx for the great implementation of the APF. Now if only there was a spare
switch? Maybe when Santa brings me a P3 I could toggle the APF from there?

 Bingo!  I've long thought that Kenwood had rested on its laurels from
 the TS-520/TS-820/TS-830 era.  That's not say that some of their later
 products weren't good, just that they had lost their edge, especially to
 Yaesu in the early '90s.

 And Larry, you're right, from a technical perspective, the 590 receiver
 schema is really Goofy!

 It strikes me as rather odd as well.  I suppose that the Kenwood
 engineers and management have their reasons, but wow!  When I read
 preliminary information on it, I came to the conclusion that it was more
 complicated than it needed to be.

 Elecraft's well targeted market niche is being attacked from above by the
 FTdx5k and from below by the 590 and to a lesser extent, the Eagle.  Most of
 the erosion will be in the lower side of the equation.  Main K3 competitor
 is really the IC7600, and technically it leaves a lot to be desired and is
 not as customizable, but undercuts K3 in price and it has the Icom mystique
 by association.  Icom has done a masterful job at brand identity.

 And here I thought ICOM stood for I Can Only Monitor!  ;-)  To be
 fair, I've only owned two Icom transceivers over the years, an IC-290A
 2m all mode that was the first commercial rig I bought in 1985 and later
 a 4AT HT.  Both served their purposes well.  Early on I would fall into
 the Kenwood camp for HF gear and later Yaesu for all my gear.  In fact,
 I was all Yaesu until I received the K3 last month.  I liked the idea of
 performance that rivaled the big boxes in a size near that of my
 FT-890AT.  Watching this list and seeing Elecraft's interaction with its
 customers won me over.

 So the K3 niche is still rather exclusive, but eroding a little bit.

 I'll agree the K3 is niche, but I'm not sure it's saleas are eroding.
 Of course I don't have sales figures, but it would appear that at least
 100 more have sold since I got mine on the air about a month ago which
 seems healthy for a niche product that is positioned toward the high end
 of a niche hobby.  Considering as well that the overall economy is not
 doing as well as when the K3 was introduced, I'd say it's doing quite
 well.

 I'd also submit that as mentioned earlier in this thread that there are
 those who would not be comfortable buying a K3 for their main
 transceiver as they feel more comfortable going with a product from one
 of the brand names.  I can understand that as it took me a while to
 accept the idea as I spent several months evaluating Elecraft as a
 company before I took the plunge.  The established players are known
 quantities while Elecraft is still building its reputation in the larger
 amateur radio community.  I'm a bit of a risk taker on things like this
 so I suspect I'll receive some questions about the K3 at tonight's club
 meeting.

 Elecraft is a lot like Honda in the mid 70's.  Pick the niche, build a solid
 product and back it with uncompromising service, winning one customer at a

 I take for granted you're referring to Honda cars.  In motorcycles, they
 were a juggernaut at the time.  Which allowed them to bring products

Hello Joe,

Dual watch is not equal to dual receivers for sure.  Therefore, I did not add 
in 
KRX3 in cost comparison.  I am afraid that adding the cost of KRX3 is not a 
like 
with like comparison.

My cost comparison is K3 single receiver Vs  IC7600 single receiver.  To this 
end, dual watch in IC7600 is simply an additional feature to my convenience.

I once used XV144 with IC7600.  The band spectrum of IC7600 under 'dual watch' 
can read both the uplink and downlink of a 2m repeater i.e. I read both 
145.650Mhz and 145.050 Mhz in the band spectrum.  This is a very convenient 
feature.

Re: [Elecraft] K3 - KDVR bug?

Well, that eliminates using the K3 with VOX in the manner I described for 
speaking the first (variable) part of a contest exchange and using the DVR for 
the second (fixed) part as in Sweepstakes.  MY logic says that if the DVR can 
start while PTT is activated by the footswitch it should do the same when the 
PTT is activated by the VOX.  I hate to suggest it, but maybe this could be one 
more option on the DVR operation?

Re: [Elecraft] OT: Problems with Icom 756 Pro III internal tuner

Hello group!

I'd like to close this thread now; many thanks to everyone who replied
off-list with suggestions and assistance.  In summary, I was referred to an
Icom technician who I was able to speak too over the phone and describe the
situation.

The tech told me that he sees this behavior on many Pro II's and Pro III's.
He also stated that a 10% insertion loss seems to be the norm with these
radios, although he didn't have any documentation officially stating so.
Finally, he confirmed that the Icom uses a T network for its ATU versus the
modified Pi/L C-in/C-out network the K3 uses.  That obviously explains the
huge difference in efficiency.

With that said, I'll leave well enough alone.  He believes from my
description that the Pro 3 is working within manufacturer permitted
tolerances.

This experience also reconfirmed my belief that our K3's are superbly
engineered products, and I'm glad to be a part of this family.

Mni tnx,

 Greetings fellow Elecrafters,

 I'm sorry for emailing this question to the group, but the folks on this
 reflector are a smart bunch.  Maybe someone could give me some advice or
 suggestions.  I posted this question to the Icom 756 Pro III group and QRZ,
 but no one seems to have an answer.

 I'm diagnosing a problem with an Icom 756 Pro III.  It's tuner's insertion
 loss is quite high.  For example, when the tuner is off, sending an
 unmodulated FSK carrier shows the transceiver putting out 100W.  As soon as
 the tuner is activated, power drops by 10-15%.  That's a lot of power being
 dissipated somewhere, and I don't think it's good especially for 100% duty
 cycle modes.  It doesn't matter whether the Icom is connected to a dummy
 load or resonant antenna.  The results are always the same on every band.

 In comparison, the K3's tuner seems to be incredibly efficient.  If there
 is a loss of output power on the K3 whenever its tuner is inline, it's not
 noticeable.  More often than not, power increases when the K3 finds a good
 impedence match.

 I've gone as far as recalibrating the Icom's tuner.  This was done by
 terminating the remote jack on the rear panel, and entering the tuner
 service mode.  The tuner calibration process completed with no errors
 reported by the Pro3.

 Any suggestions?  I'm going to call Icom support tomorrow to see what they
 say.

It's for when you want to use the mic with something that does not 
provide voltage for the electret element.  Contrary to what some Yamaha 
descriptions says about the mic, it is an electret mic, not a dynamic 
mic.  You do NOT need it with a K3. Simply plug it into the rear panel 
mic connector, turn on the bias (see the manual), and adjust levels just 
like you would with any other mic (again, following the directions in 
the manual.
 Plus how do you like the mic on the cm500?

I love it, and so do most who have used it.  It provides very clean 
audio, and, using TXEQ can easily be made very competitive for 
contesting and DXing, or more mellow for casual rag chewing. It sounds 
better than most Heil mics I've heard.  Recommended TXEQ for the CM500 
is max cut of the two lowest bands, somewhere between 6dB cut and max 
cut of the third band, depending on your voice, and flat (0 dB) for the 
remaining bands. Use the LOW setting for Mic Gain in the Menu.

[Elecraft] T1 Remote Tuning and Power Supply

2010-11-16 Thread GeorgeP1111

I am in the process of slowly reconfiguring my station for the inevitable
future move to a condo or antenna restricted area where I will have to play
the Stealth antenna game. My station comprises of a Yaesu FT-817ND, W1
PWR/SWR Indicator, 3ft diameter remotely tuned home built 20m-10m Magnetic
Loop antenna, and a 80/40 meter Trapped Dipole using the T1 Tuner for fine
tuning. I figure I can always wrap plastic flowers around the Mag Loop and
pass it off as a Christmas Wreath, but I will still want some sort of
outdoor wire using the T1 tuner for the lower bands.

I want to use the T1 at the antenna end vs the radio end as I am now. I
know that the T1 has the ability to be remotely tuned via the port on the
side, but I want to kick it up a notch. I'm running DC up the coax to
control the capacitor motor in my Mag Loop using the standard
inductor/capacitor configuration, and I want to follow the same plan for the
T1. The idea is to use a push button to supply the 9v (I'll probably use a
higher voltage and reduce it at the tuner to compensate for line loss) via
the coax to the T1 (vs using the internal battery) and a LM556 Dual Timer at
the T1. Key Up, Push and hold the button, the T1 turns on and boots up and
at the same time the LM556 starts timing. After a preset amount of time (1
second?) the LM556 would pull the Tune line low via a Optical Isolator for
say 1 second starting the Tune function. Watch the SWR on the FT-817 or the
W1 and when it stabilizes low, release the button and unkey.

Granted, I could leave the internal battery installed and just use the 9v to
pull the Optical Isolator low but by adding the LM556 I can eliminate the
battery as well.

I know the power via coax will work, and the LM556 (or even a PIC) will
work, so I guess I'm asking if there is a problem with turning On/Off the
power to the T1 and is 1 second enough time to stabilize prior to initiating
Tune?

tnx

Re: [Elecraft] K3 - mods for Mars/CAP

2010-11-16 Thread k2qi . nyc

Pse send an email to Elecraft support. They have a utility that when run once, 
will remove out-of-band TX lockouts.  You will probably need to install the 
KBPF3 as well if you don't have one already.

Re: [Elecraft] K3 - mods for Mars/CAP

2010-11-16 Thread Ron D'Eau Claire

William, send an e-mail to support at elecraft dot com and they'll provide
you with firmware to load using the K3 utility that opens up your K3 for
MARS frequencies. 

Not sure about CAP (Civil Air Patrol?). The FCC forbids the use of any
equipment for communications in other services that isn't type-approved for
that service other than those specifically approved by the FCC, such as MARS
operations. 

My gosh, is that LARC the Lockheed Amateur Radio Club? I'm an old Lockheed

It is handy in the event that the wrong message is being sent to interrupt

a CW message with a simple tap of the paddle.  I find this especially true

I used the Rework Eliminators UN-PCB kit to build an option-ready K2. 
 Many thanks to Mychael (aka the Toroid-Guy) AA3WF for the excellent job on

Dr Martin,

I have not had this experience with any of the firmware versions; I have
been switching between many different releases as of late to help with some
beta testing.

I do not have the LPF installed yet.  I will be receiving one soon though.
I find it hard to believe that the LPF could have something to do with this
issue though; others would have mentioned it on the reflector.

Have you sent a message to K3 support?

2010-11-16 Thread Benny Aumala

Nice to see new good rigs on market.
We have plenty to choose, it is clearly bonus for all hams.

When K3 came I told this RX architecture will soon be a standard
(as Rob Sherwood told long time ago).

To-day we have K3 and welcome Kenwood back again with TS590.
There is TT 599 Eagle and now this FT5K. Fine rigs all, and available. 
Waiting for Icom.

Ft5K has possibility for class-A PA, which is a bonus for everybody on 
SSB bands.
This could be copied by other manufacturers, too.

But I am happy with my K3 s/n 119 with latest softwares.
Service from Elecraft to Finland is impeccable.
We hams live good times.

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP

Hi Benny,

Only new Icom expected is the IC-9100 Daylight to DC box.  Looks
interesting, and would most likely be compared to the Kenwood TS-2000.

The receiver is a double conversion superheterodyne. They claim +30 dBm
IP3.  How they tested that, I don't know.  Their promotional material also
states that the first receiver has a 15 KHz filter for the first IF, and 3/6
KHz filters are optional.  Not sure about the second receiver.

Price is another issue.  If you look at Icom's market pricing strategy, then
expect this rig to be somewhere in the neighborhood of $4,000 without the
1.2GHz module or additional filters.  Maybe, and this is just my estimate,
that fully loaded will probably be somewhere around $4500.

I'm waiting to see what reviewers have to say before jumping to
conclusions.  One thing that I can say right off the bat, is that I wish it
had the screen from the 7600 or 7700.  Right now, it looks like they took
the LCD panel straight off an Icom 746.

[Elecraft] K3 - KDVR bug?

2010-11-16 Thread Ralph Parker

...At the very least, there should be a software switch to disable it.
A MAJOR reason for using DVR is to allow you to slurp coffee...

...or sneeze, or comment to myself on the operating skills of the previous
contact, or yell just a minute, honey - while the DVR is calling CQ.
I've just put my good ol' W9XT Contest Card away after many years of
successful operation with NA, and the KDVR is waiting in the mailbox.
I guess I'll have to learn some new techniques. I never use VOX anyway.

Re: [Elecraft] OT (Yamaha Cm 500)

2010-11-16 Thread Joe Subich, W4TV


 Recommended TXEQ for the CM500 is max cut of the two lowest bands,
 somewhere between 6dB cut and max cut of the third band, depending
 on your voice, and flat (0 dB) for the remaining bands.

While I agree with Jim on the lowest three bands, I strongly prefer
a 3 to 6 dB/octave rising characteristic for the top three bands
(e.g., +3, +5, +6 or +6, +10, +12).  The rising characteristic helps
considerably with clarity and the ability to cut through the crud.

 It's for when you want to use the mic with something that does not
 provide voltage for the electret element.  Contrary to what some Yamaha
 descriptions says about the mic, it is an electret mic, not a dynamic
 mic.  You do NOT need it with a K3. Simply plug it into the rear panel
 mic connector, turn on the bias (see the manual), and adjust levels just
 like you would with any other mic (again, following the directions in
 the manual.
 Plus how do you like the mic on the cm500?

 I love it, and so do most who have used it.  It provides very clean
 audio, and, using TXEQ can easily be made very competitive for
 contesting and DXing, or more mellow for casual rag chewing. It sounds
 better than most Heil mics I've heard.  Recommended TXEQ for the CM500
 is max cut of the two lowest bands, somewhere between 6dB cut and max
 cut of the third band, depending on your voice, and flat (0 dB) for the
 remaining bands. Use the LOW setting for Mic Gain in the Menu.

Re: [Elecraft] K3 - KDVR bug?

2010-11-16 Thread Iain MacDonnell - N6ML

I pushed for the ability to interrupt DVR playback with PTT
(footswitch) activation, but I thought the way it ended up, the DVR
would start playing even if PTT was asserted, but would stop if PTT
was (re-)asserted after it had started playing. I don't have my K3
at-hand to try this at the moment. I expect VOX activation is
considered the same as PTT in this context, but not 100% sure... I
don't use VOX.

 Whoever set that goal made a BIG mistake. At the very least, there
 should be a software switch to disable it.

 A MAJOR reason for using DVR is to allow you to slurp coffee or chew
 munchies while you're sending an exchange or calling CQ.  If the live
 mic stops DVR playback, it makes that virtually impossible.

Re: [Elecraft] OT (Yamaha Cm 500)

2010-11-16 Thread Alan Bloom

Jim and Joe,

What do you think of the idea of adjusting the equalizer so that the
peak spectrum is flat across the SSB bandwidth?  With my voice I had to
considerably attenuate the low audio frequencies and boost the highs to
achieve that.

There's a way to measure the transmitted spectrum using a P3, as
described in the most recent version of the Owner's Manual.  I ended up
with:

50 Hz   -16 dB
100 Hz  -16 dB
200 Hz  -16 dB
400 Hz  -10 dB
800 Hz  -16 dB
1.6 kHz   0 dB
2.4 kHz  +3 dB
3.2 kHz  +6 dB

(The -16 dB at 800 Hz was based on someone's suggestion that little
voice information occurs around that frequency.  Otherwise it would
probably have been -3 or -6 dB.)

 While I agree with Jim on the lowest three bands, I strongly prefer
 a 3 to 6 dB/octave rising characteristic for the top three bands
 (e.g., +3, +5, +6 or +6, +10, +12).  The rising characteristic helps
 considerably with clarity and the ability to cut through the crud.

Nah ... they're just junk, especially if you only operate CW or digital modes.  
  Send them to me, and I'll pay the postage ... :-)



Or ... put them on eBay or QRZ or eHam or the boatanchors and AM reflectors on 
QTH.net.  You'll probably find eager takers on both if they are in decent 
condition.  

Or ... use them yourself.  Both are very good vintage microphones and can add a 
bit of class to even a silicon radio station :-)

Re: [Elecraft] K3: Unable to download 4.22

2010-11-16 Thread Bill VanAlstyne W5WVO

Just as an FTP suggestion -- If you are using Mozilla Firefox as a browser 
(which IMO everyone should be), there is an FTP client plug-in called 
FireFTP. It is a seriously awesome FTP app, it's FREE, and it works on MacOS 
and Linux as well as on Windows of all flavors. You get a drag-and-drop 
capable dual file system window -- one window for the FTP site, another for 
your local file system.

If you ever use FTP, just being able to run this FTP plug-in client is 
reason enough to upgrade your browser to Firefox (as if there weren't 100 
other reasons). Can't recommend this FTP client highly enough.

[Elecraft] {Elecraft} SM-20 Mic wired for K3 for Sale

2010-11-16 Thread North Pole

A casualty of last weekend’s installation of KXV3A, KRX3, and KBPF modules was 
losing the 8 volts on pin 6 of the K3’s mic plug.  The Icom SM-20 was just 
purchased new  a few months ago and is in like new condx with original 
box/paper work.  The SM-20, being an electret condenser mic requires the 8 
volts to work.  I am not up to repairing or replacing the smd rf choke or 
whatever to restore the 8 volts to pin 6 on the foster plug?

I have decided to take the easy way out and will be installing a PR-781 or 
PR-35 Heil on a boom,  for the little use a mic sees in my shack!   Thought I 
would offer the mic on this forum prior to listing on QTH.

BTW I also built the P3, Friday night, very easy build and what a terrific 
addition to the K3.  I was not particularly excited about getting a panadapter 
(owned 756 Pro previously) but the P3 is absolutely awesome!  Great job Team 
Elecraft and thanks for the recent firmware enhancements, really enjoying the 
new APF feature.  

Please email me off list or call 906 632-6827 re:  SM-20, thinking $125.00 
shipped conus will get it to you.  Thanks – Larry Davis  W8CCY

I believe some of the older Kenwood's also had a low MHz IF out - 8.8 or 8.9
MHz.

I know this because I have a Kenwood SM-230 that requires an 8.9 MHz IF

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP

2010-11-16 Thread gdaught6

 I believe some of the older Kenwood's also had a low MHz IF out - 8.8 or 8.9
 MHz.
 
 I know this because I have a Kenwood SM-230 that requires an 8.9 MHz IF
 input.

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP

2010-11-16 Thread Ron D'Eau Claire

Sometime in the 1960's or early 70's one company started offering a 9 MHz
filter at a decent price that was widely used by homebrewers back then and
the subject of many QST and ARRL handbook designs as well as a number of
commercial rigs. 

Obviously, those rigs up-converted the lower MF frequency bands and
down-converted the higher MF frequency bands.

Early M.F./H.F. superhetrodyne receivers all down converted to an I.F. in
the low MF range (usually 455 kHz) but designing input filters for the M.F.
range that would adequately reject the image response at 2X the I.F. became
very difficult. Filter technology limited the selectivity available at
higher frequencies, forcing designers to use a low frequency I.F., but the
press was on from the beginning for better I.F. filters at higher
frequencies.

Like all designs, it's always a compromise. The best designers are those who
make the best compromises using the components available at an acceptable
price.

[Elecraft] K3: Are the birdies really birdies

2010-11-16 Thread Mike K2MK

There's a very interesting item in December's QST The Doctor is In feature
(page 48 right column). Receiver birdies turned out to be caused by a noisy
router. I have learned to live with 10 meter birdies on my K3. But lately
I've been active on 12 meters and there is an S5 birdie at about 24900KHz.
So after reading the article I started unplugging cables on my wireless
router (which is in another room from my K3). Whoa, what's this? Birdies
come and go as I unplug the router power line or unplug the CAT 5 cable
going to the shack. Ditto in the shack. If I unplug the CAT 5 from the wall
or from the PC the birdie on 12 meters disappeared. Moving on to 10 meters I
discovered that all of the prominent birdies also disappeared. I haven't
done a thorough investigation but I suspect they might all be gone.

Of course that was only step one. I still need an internet connection on my
shack PC so I'm currently experimenting. Snap-on ferrite cores had no
effect. Moving the shack CAT 5 cable away from other radio related cables is
having a positive effect. Next I'm going to try a shielded CAT 5 cable from
the wall to the shack PC. But of course the cable wiring in the wall to the
router is not shielded so I don't have high hopes of solving it in this way.
But at least I'm on the right track and I'm sure I'll find something that
works eventually.

[Elecraft] DVR Questions

Following K9YC's advice, I set my TX EQ up to roll off the lows and help 
out the highs.  I got very good reports on my audio in the CQ WW SSB. 
I'm using the Heil Proset from Elecraft [electret I think].  I have the 
RX EQ set to approximate the response curve of my hearing aids [although 
16 dB is nowhere near enough] which don't work with the cans.  Getting 
ready for ARRL SS SSB, I'm pondering:

1.  Does the TX EQ apply to what I record in the DVR, or does it apply 
when the DVR plays back into the TX?  I'm presuming it doesn't apply 
twice, on record and playback.

2.  When I play the DVR back, does the monitor signal reflect whatever 
TX EQ I set?

3.  Is it also conditioned by my RX EQ settings?

4.  If I record someone off the air, does my RX EQ settings affect what 
is recorded?

5.  If I play the recording back to him, is my TX EQ applied to it?

This is all probably answered somewhere in all the documentation, notes, 
and archives, I just don't think I'll recognize it if I were to find it.

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP

2010-11-16 Thread Don Wilhelm

  Actually, the 9 MHz IF got started and gained momentum from the first 
SSB phasing generators.  Some of the first SSB transmitters were phasing 
types with the 9 MHz IF - using a 5.0 to 5.5 MHz VFO, one could cover 
3.5 to 4.0 MHz and also 14.0 to 14.5 MHz with the same 9 MHz generator.  
Transceivers were only a dream at that time.  Receivers did not normally 
use a phasing approach.

Then McCoy came out with a reasonably priced 9 MHz crystal filter that 
made filter SSB transmitters possible with the same 9 MHz IF.  
Transceivers were now possible with that filter, and there were several 
homebrew designs as well as some commercial implementations of 
transmitters and receivers and transceivers using a 9 MHz IF.

Another observation - sideband suppression and top-notch performance 
were difficult using analog phasing methods (although Rick Campbell KK7B 
does have some very good analog designs), the DSP algorithms are a 
perfection of the phasing method of SSB generation and reception, so we 
have come full circle with the advent of DSP implementations.

As far as the advantages of down conversion - that was very 
successfully implemented in the K2, although there were other homebrew 
implementations.  The single conversion down-conversion receiver in the 
K2 proved its worthiness to many operators while the rest of the world 
was using up-conversion to obtain full 0.1 to 30 kHz continuous coverage 
and few 'birdies'.  Birdies are inevitable with a down-conversion 
scheme, and the challenge is to keep them out of the ham bands.

Re: [Elecraft] K3: Are the birdies really birdies

2010-11-16 Thread Don Wilhelm

  Mike,

OK, you are finding good information about the source of the birdies 
(which are not really birdies, but real signals).
If you can locate your antenna away from the router and ethernet cables, 
your problem will diminish.  My computer network is confined to the 
inside of a stucco covered house with its steel mesh coating, so I 
(sort-of) live in a shielded box.  The antennas are located at least 80 
feet from the house, so I hear few of those troublesome radiation 
effects from the computer netowrk devices.  The downside is that I 
cannot connect my laptop to the network access point if I am more than 
25 feet from the house.

So, if you can, locate the antennas as far away from the noise source as 
possible, and if that is not possible, use ferrites and other shielding 
means to lower the radiation into your receiving antenna.

This is not a K3 (K2, K2, YaseuKenCom) problem, but it is a situation 
that must be dealt with if one is to continue to enjoy the benefits of 
networking and internet access provided by routers and switches and 
access points, they all generate RF that our sensitive receiver can hear.

Hi Mike,

They're not birdies, but real signals. See what happens when you disconnect
your antenna. If they were birdies, therefore originating from within the

Re: [Elecraft] K3: Are the birdies really birdies

2010-11-16 Thread Tim Tucker

I long ago diagnosed several of my RFI problems on ethernet devices
throughout the house.  I tried everything to get rid of it including making
special ethernet jumpers I put at the source devices with ferrite and
by-pass capacitors between the offending pair of wires (the TX/RX wires).
Of course the caps worked, but since the ethernet signal is AC, it also
killed the network, LOL!

Shielded cable on long runs that is grounded at both ends definitely makes a
big difference...at least it did for me.  It doesn't get rid of it entirely,
but it helps.  Some devices are worse than others, and of course it's more
pronounced on some bands than others.

2010-11-16 Thread Johnny Siu

Hello Don,

Very true indeed.  Downward conversion is a good cost Vs performance solution 
for radio targeting at ham band.

Elecraft's selection of downward conversation is clever because both K2 and K3 
are targeting ham operators.

主題： Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP

  Actually, the 9 MHz IF got started and gained momentum from the first 
SSB phasing generators.  Some of the first SSB transmitters were phasing 
types with the 9 MHz IF - using a 5.0 to 5.5 MHz VFO, one could cover 
3.5 to 4.0 MHz and also 14.0 to 14.5 MHz with the same 9 MHz generator.  
Transceivers were only a dream at that time.  Receivers did not normally 
use a phasing approach.

Then McCoy came out with a reasonably priced 9 MHz crystal filter that 
made filter SSB transmitters possible with the same 9 MHz IF.  
Transceivers were now possible with that filter, and there were several 
homebrew designs as well as some commercial implementations of 
transmitters and receivers and transceivers using a 9 MHz IF.

Another observation - sideband suppression and top-notch performance 
were difficult using analog phasing methods (although Rick Campbell KK7B 
does have some very good analog designs), the DSP algorithms are a 
perfection of the phasing method of SSB generation and reception, so we 
have come full circle with the advent of DSP implementations.

As far as the advantages of down conversion - that was very 
successfully implemented in the K2, although there were other homebrew 
implementations.  The single conversion down-conversion receiver in the 
K2 proved its worthiness to many operators while the rest of the world 
was using up-conversion to obtain full 0.1 to 30 kHz continuous coverage 
and few 'birdies'.  Birdies are inevitable with a down-conversion 
scheme, and the challenge is to keep them out of the ham bands.

 commercial rigs.

 Obviously, those rigs up-converted the lower MF frequency bands and
 down-converted the higher MF frequency bands.

 Early M.F./H.F. superhetrodyne receivers all down converted to an I.F. in
 the low MF range (usually 455 kHz) but designing input filters for the M.F.
 range that would adequately reject the image response at 2X the I.F. became
 very difficult. Filter technology limited the selectivity available at
 higher frequencies, forcing designers to use a low frequency I.F., but the
 press was on from the beginning for better I.F. filters at higher
 frequencies.

 Like all designs, it's always a compromise. The best designers are those who
 make the best compromises using the components available at an acceptable
 price.

 There is a serious misconception by some true believers that Elecraft
 invented down-conversion (or at least conversion) to an i-f in the 8 to 9
 MHz range.

 Nothing could be further from the truth, and I know that the folks at
 Elecraft would never claim as much.  I had a Henry Radio Tempo-1 (Yaesu
 FT-200) back when radios warmed up the shack.  It was a 9 MHz i-f
 transceiver.

Re: [Elecraft] K3: Are the birdies really birdies

2010-11-16 Thread ab2tc

Hi,

I am still working on mine. My main problem is that I have yet to find a
source of ferrites that are big enough to thread cables with connectors
through (the snap-on ones are totally useless) and effective on HF. I have
borrowed ferrites from the kits we have at work but they are only moderately
effective below 30MHz (regulatory requirements are more severe at VHF so
companies tend to focus on that). My birdies are definitely picked up by
my antennas. When I switch to the dummy load, it's mostly dead quite
although my MFJ tuner/switch/dummyload is not extremely well shielded. I am
convinced that most of the radiation from the router is through the AC power
house wiring. I say that because I do not have that much Ethernet cabling
beyond the immediate vicinity of the router and the computer cluster close
to it. The birdies are also worst on the antennas that are parallel with
the long axis of the house - not unexpected if the AC wiring is the main
radiator.

It's a balanced mic, so to connect it to a ham rig, connect one of the

return, and connect the shield to the chassis. No other matching needed.

I don't remember the 630, but my guess is that it would work too, and

Re: [Elecraft] K3: Are the birdies really birdies

2010-11-16 Thread Mike K2MK

Don and James,

You are both correct. I was pretty sure the S5 router noise was a birdie as
I had already switched to my dummy load. But now I disconnected the PL259
from the back of the K3 and the router noise on 12 meters is down to S1. So
it is probably being picked up by the 4 cables between the K3, amplifier,
power meter, antenna switch, and dummy load.

The real birdies are still there with no antenna cable connected. I had done
birdie reduction some time ago by rearranging the RF cables inside the K3
(and taping them in place with blue painter's tape). The real birdies are
mostly S1 and S2 which is something I can live with.

Thanks for the enlightenment.

Mike,

OK, you are finding good information about the source of the birdies
(which are not really birdies, but real signals).
If you can locate your antenna away from the router and ethernet cables,
your problem will diminish. My computer network is confined to the
inside of a stucco covered house with its steel mesh coating, so I
(sort-of) live in a shielded box. The antennas are located at least 80
feet from the house, so I hear few of those troublesome radiation
effects from the computer netowrk devices. The downside is that I
cannot connect my laptop to the network access point if I am more than
25 feet from the house.

So, if you can, locate the antennas as far away from the noise source as
possible, and if that is not possible, use ferrites and other shielding
means to lower the radiation into your receiving antenna.

This is not a K3 (K2, K2, YaseuKenCom) problem, but it is a situation
that must be dealt with if one is to continue to enjoy the benefits of
networking and internet access provided by routers and switches and
access points, they all generate RF that our sensitive receiver can hear.

Of course that was only step one. I still need an internet connection on

You should be able to read (some of) them at the ARRL web site if you are an

If not, you can try the QST View CD-ROMs.  

ARRL no longer sells the CD-ROMs but you might be able to get them from the

http://homepage.mac.com/chen/w7ay/QST%20Browser/index.html

A funny anecdote is that the 1950-1959 QST View was the first set to disappear 
as ARRL was selling remaining stock.  I had people who stumbled on QST 
Browser but could not find the 1950-1959 set to buy, so they wrote me to see 
if I knew of secret stashes :-).  I suspect that it could be due to the ham

they'd drooled over the ads of things like the S-Line which they could not 
afford as teenagers :-).  ARRL sold out of them first, then vendors like Texas

There are two ways the noise escapes the box. One is direct radiation 
from the box. The other is common mode current on the Ethernet cable and 
sometimes even the power cable.  You can make a BIG dent in the cable 
radiation by winding multiple turns of EVERY Ethernet cable through a 
#31 or #43 ferrite core. SINGLE TURNS (BEADS) WILL NOT WORK except on 6M 
and 2M.  5-7 turns on a 2.4-in o.d. toroid is a good starting point.

Note that BOTH ENDS of any digital connection, including an  Ethernet 
connection, can produce this trash, so if the Ethernet cable is longer 
than about 0.15 wavelengths at a frequency where you hear this stuff, 
you are likely to need chokes at both ends.

The most common of the birdies coming from modems are around 14,030 kHz, 
21,052 kHz, the bottom of 10M CW, and the bottom 100 kHz or so of 6M. 
There are also some on 30M. See my RFI tutorial for a list.  I'm a CW 
guy, so those are the ones I hear. If you work SSB you get to identify 
your own. :)

Note also that each Ethernet box has its own free-running clock, so each 
box is on a different frequency.  It is very common to kill your own 
trash but still hear your neighbors. I did in my Chicago residential 
neighborhood. When chasing these birdies, kill power to your Ethernet 
box first to identify which is yours. Otherwise you'll chase your tail.

Here in CA, I have no wired Ethernet at all, doing everything on WiFi.  
Works a treat, as our friends in the UK would say.

[Elecraft] K3: NB/NR and AM SWL?

Hello group,

What are the optimal NB/NR settings for use with AM and AM-S?  I'm
interested in using those features for those times when I SWL, but can't

example seems to reduce the dynamic range, making audio sound very quiet and
muffled.  The NB on the other hand starts to distort the audio past anything

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP

2010-11-16 Thread Igor Kosvin

I don't recall, does the IC7600 has independent second receiver? Perhaps you 
can ADD second receiver to it? Can you ADD 500 Hz or 250 Hz roofing filter to 
it? No? Too bad, I will pass. Still not enough bang for the buck.

Subject: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP

Hello Nate,

In relation to your comments about IC7600, I would add the following:

1.  There is 'manual notch within AGC loop' in IC7600.  This function is very 
useful when I use it to notch out a strong offending carrier right adjoining to 
my wanted desired weak signal.  Since the notch is within AGC loop, the wanted 
weak DX signal will pop out right from the noise ground after the 
carrier is notched.  The desense of AGC by the strong carrier disappears at the 
same time.

I did an A/B comparison of the above during the recent CQ WW SSB contest.

2. When we calculate the cost for comparison, we have to add P3 to K3 to bring 
it in line.  Bearing in mind, IC7600 only costs US$3,250 in Hong Kong

I am still running my K3 but just plainly spell out the fact as above.
 cheers,

 TS950/TS850 days! Even from TS520 days!

Bingo!  I've long thought that Kenwood had rested on its laurels from
the TS-520/TS-820/TS-830 era.  That's not say that some of their later
products weren't good, just that they had lost their edge, especially to
Yaesu in the early '90s.

 And Larry, you're right, from a technical perspective, the 590 receiver
 schema is really Goofy!

It strikes me as rather odd as well.  I suppose that the Kenwood
engineers and management have their reasons, but wow!  When I read
preliminary information on it, I came to the conclusion that it was more
complicated than it needed to be.

 Elecraft's well targeted market niche is being attacked from above by the
 FTdx5k and from below by the 590 and to a lesser extent, the Eagle.  Most of
 the erosion will be in the lower side of the equation.  Main K3 competitor
 is really the IC7600, and technically it leaves a lot to be desired and is
 not as customizable, but undercuts K3 in price and it has the Icom mystique
 by association.  Icom has done a masterful job at brand identity.  

And here I thought ICOM stood for I Can Only Monitor!  ;-)  To be
fair, I've only owned two Icom transceivers over the years, an IC-290A
2m all mode that was the first commercial rig I bought in 1985 and later
a 4AT HT.  Both served their purposes well.  Early on I would fall into
the Kenwood camp for HF gear and later Yaesu for all my gear.  In fact,
I was all Yaesu until I received the K3 last month.  I liked the idea of
performance that rivaled the big boxes in a size near that of my
FT-890AT.  Watching this list and seeing Elecraft's interaction with its
customers won me over.

 So the K3 niche is still rather exclusive, but eroding a little bit.

I'll agree the K3 is niche, but I'm not sure it's saleas are eroding.
Of course I don't have sales figures, but it would appear that at least
100 more have sold since I got mine on the air about a month ago which
seems healthy for a niche product that is positioned toward the high end
of a niche hobby.  Considering as well that the overall economy is not
doing as well as when the K3 was introduced, I'd say it's doing quite
well.

I'd also submit that as mentioned earlier in this thread that there are
those who would not be comfortable buying a K3 for their main
transceiver as they feel more comfortable going with a product from one
of the brand names.  I can understand that as it took me a while to
accept the idea as I spent several months evaluating Elecraft as a
company before I took the plunge.  The established players are known
quantities while Elecraft is still building its reputation in the larger
amateur radio community.  I'm a bit of a risk taker on things like this
so I suspect I'll receive some questions about the K3 at tonight's club
meeting.

 Elecraft is a lot like Honda in the mid 70's.  Pick the niche, build a solid
 product and back it with uncompromising service, winning one customer at a
 time.

I take for granted you're referring to Honda cars.  In motorcycles, they
were a juggernaut at the time.  Which allowed them to bring products
like the CBX to market.  By 1980 they had forced Kawasaki into catch-up
mode where Kawi had

Re: [Elecraft] OT: QST's review of the Yaesu FTDX5000MP

Regarding the IC-7700, which is a lot more expensive than the 7600, here's
what an Icom fan had to say about the missing 2nd receiver. Pay close
attention to the first bullet point.


Single HF receiver http://www.ab4oj.com/icom/ic7700/rx.html with I/Q
second mixer, offering +40dBm 3rd-order intercept point*.

   - *The single receiver should be seen not as a disadvantage, but as a
   plus.* The single receiver allows no-compromise RX performance at a
   reasonable price; BNC sockets on the rear panel, and CI-V, allow easy
   connection and synchronization of a second Icom transceiver such as the
   756Pro3 as a secondary receiver. Many prospective IC-7700 buyers already own
   an IC-756Pro3. Add http://www.ab4oj.com/icom/ic7700/2rx.html the
   IC-7700 to your existing Pro3 for the perfect contest station; use the
   IC-7700 as your main transceiver, and the IC-756Pro3 as a spotting receiver.

   - Upgrade from your IC-765 or IC-775DSP, and get the benefits of a
   spectrum scope.

I love this guy's logic. :)

Re: [Elecraft] K3: NB/NR and AM SWL?

2010-11-16 Thread Don Wilhelm

  James,

The only answer I can give is experiment.  There is no setting that is 
good for any particular mode, but the setting of NB/NR must be 
customized for the noise source.  That noise source will vary from 
location to location, and from time to time.
The best I can offer is to familiarize yourself with the controls and 
theory of operation for both NB and NR and use that knowledge to combat 
whatever form of noise you are encountering at your location.

In other words, there is no magic bullet - it depends more on the 
noise source than on the K3 capabilities.

Disconnect power from the K3, exit K3 utility, and start over: turn on

Just as an FTP suggestion -- If you are using Mozilla Firefox as a browser

FireFTP. It is a seriously awesome FTP app, it's FREE, and it works on MacOS

capable dual file system window -- one window for the FTP site, another for 
your local file system.

If you ever use FTP, just being able to run this FTP plug-in client is 
reason enough to upgrade your browser to Firefox (as if there weren't 100 
other reasons). Can't recommend this FTP client highly enough.

Re: [Elecraft] OT (Yamaha Cm 500)

2010-11-16 Thread Joe Subich, W4TV


  What do you think of the idea of adjusting the equalizer so that the
  peak spectrum is flat across the SSB bandwidth?

It's probably a good starting point but I would also listen to the
audio on a second receiver and have it evaluated by someone who can
make critical evaluation off air.

  I ended up with:
 
  50 Hz   -16 dB
  100 Hz  -16 dB
  200 Hz  -16 dB
  400 Hz  -10 dB
  800 Hz  -16 dB
  1.6 kHz   0 dB
  2.4 kHz  +3 dB
  3.2 kHz  +6 dB

I think that is doing too much cutting at the low end and not
enough boost at the high end.  Adding 6 dB at each band from
200 Hz to 3.2 KHz would make me more comfortable.  Like, Jim
I prefer to leave 50/100 at -16 regardless as they contribute
nothing to communication.

 There's a way to measure the transmitted spectrum using a P3, as

 with:

 50 Hz   -16 dB
 100 Hz  -16 dB

 (The -16 dB at 800 Hz was based on someone's suggestion that little
 voice information occurs around that frequency.  Otherwise it would
 probably have been -3 or -6 dB.)

 While I agree with Jim on the lowest three bands, I strongly prefer
 a 3 to 6 dB/octave rising characteristic for the top three bands
 (e.g., +3, +5, +6 or +6, +10, +12).  The rising characteristic helps

 mic connector, turn on the bias (see the manual), and adjust levels just
 like you would with any other mic (again, following the directions in
 the manual.
 Plus how do you like the mic on the cm500?

 I love it, and so do most who have used it.  It provides very clean
 audio, and, using TXEQ can easily be made very competitive for
 contesting and DXing, or more mellow for casual rag chewing. It sounds
 better than most Heil mics I've heard.  Recommended TXEQ for the CM500
 is max cut of the two lowest bands, somewhere between 6dB cut and max
 cut of the third band, depending on your voice, and flat (0 dB) for the
 remaining bands. Use the LOW setting for Mic Gain in the Menu.

[Elecraft] RX architecture

2010-11-16 Thread Benny Aumala

Yes,
9MHz down-conversion was standard when I homebrewed SS transceivers
in 1960-70. But architecture is also part of its components.
We do not use simple VFO any more, and much has been made to make 
injection signal pure again.
Mixers are much better (we had hot-carrier diode quads). IF DSP is new 
in down-conversion scheme.

And all is for our good.
Enjoy and smile!
