[Elecraft] K3 Shipping Status Update

2007-12-27 Thread Eric Swartz - WA6HHQ, Elecraft

We've just updated the K3 shipping Status Page.

Shipping for the weeks of Jan 2-4 and 7-11:

(Orders with deposits):  
We have a short shipping week next week, due to the New Year's holiday 
on 12/31-1/1, but we are still working over this next weekend (Dec 
29-30)  to get ahead. We're ramping up our ship rate and we will ship 
the few remaining May 3rd orders,  and the May 4, 5, 6, 7, 8 and 9th 
orders during this period.


We have also added staff (and overtime) in production and test and hope 
to beat the above plan. (We're still adding more help over the next 2 
weeks.)


73, Eric  WA6HHQ

[Elecraft] Which Heil Prosets should we carry?

2007-12-27 Thread Eric Swartz - WA6HHQ, Elecraft
Since the K3 is also compatible with the other Heil Proset boom mic 
headsets that use the HC4 and HC5 elements, which model does everyone 
like? Any favorite models?


Its not practical for us to carry them all, but I'd like to add at least 
one or two of the more popular versions to our product list.

RE: [Elecraft] Proset with Kenwood?

2007-12-27 Thread Joe Subich, W4TV

The Elecraft version of the Proset uses an electret mic that 
will not work with a standard Kenwood mic input.  You will 
need to add a resistor/capacitor network inside the Kenwood 
radio or inside the Foster plug on the Proset adapter.

Re: [Elecraft] KNB2 diagnosis

2007-12-27 Thread Samuel Strongin
To all I love my K2 it is a great radio,BUT the noise blanker well it sucks. 
It works on some noise to some extent that's it. It is the weak point in the 
radio,and I live with it. I allways thought Elecraft would come up with a 
better design.

Chris,
I installed a KNB2 in my K2 a few months ago. I didn't think it worked until
I tried the scratching of Q21 as recommended.

With the top off and background noise coming from the speaker, I toggled
from NB1 to NB2 to OFF while I scratched the case of Q21. It worked. I saw a
definite difference.

With the NB on I then toggled between both threshold levels and heard the
difference also.

Give this technique another try. Use a small screwdriver to scratch with.

Good luck.

John N2YC

I've never been convinced that my KNB2 worked as planned. I have the K2 open
today to install the K160RX, and decided to work on the KNB2.

I found the archive messages about "scratching" Q21. I can only get any
noise out of this with the pre-amp on - don't know if that's as expected or
not. No setting of the NB changes the audio through the headphones.

I can tap Q21 and get a pulse on my scope, or rub the case back and forth to
get something a little more continuous (but still hard to capture on the
scope - despite being quite evident in the headphones).

Some of the time, my pulses just die at the output of R8, which goes to
ground via L1. I'm not sure exactly what I do differently when the pulse
gets past - perhaps just how hard I'm tapping?

If I have the NB turned off, the signal stops at pin 4 of U1 - I see pulses
there, but not at pin 1.

If I have the NB turned on, pin 4 is biased and pin 1 is biased even higher
- but I don't see the pulses at either pin.

RE: [Elecraft] KNB2 diagnosis

2007-12-27 Thread Ron D'Eau Claire
Ha, ha! No "fix". It's  a way of generating noise to demonstrate that the
KNB2 is working. It produces the sort of high-impulse, short duration noise
the KNB2 is designed to handle. 

A lot of operators note that it doesn't do much for random QRN with fairly
wide pulses at varying intervals. That's not what a "noise blanker" is best
suited for suppressing. Blankers do a wonderful job on repetitive spikes
such as those produced by cheap lamp dimmers, auto ignition, etc. The
"scratch" is just a way of testing it if one doesn't have a suitable noise
source handy.

Re: [Elecraft] KNB2 diagnosis

2007-12-27 Thread Don Wilhelm

Stan,

Scratching Q21 is certainly NOT a *fix* by any means!!!  It is a 'GO -- 
NO-GO' test only.
BUT it is one 'no-tools' method that can effectively produce the noise 
that the KNB2 is capable of suppressing.  Of course, the preamp must be 
on to bring Q21 into the circuit.

Re: [Elecraft] Mountain Ops Tac Pac replacement?

2007-12-27 Thread Leigh L Klotz, Jr.

I use the Bail Out Bag 5 from http://countycomm.com/BAILOUTBAGGEN5.htm

It is $40 and comes in black (which I have) and green (which they don't 
have).


The side pocket holds a soft plastic soap dish into which I can fit a 
Palm Paddle.  The lower horizontal zippered pocket is good for DC 
cables.  The front pockets are good for mics.  The fat side pocket holds 
logbooks and pens and would probably also fit a Gamma HPS1a power 
supply.   It also has pockets good for 9V batteries, flashlights, 
headphones, etc.


The K2 and a folding solar panel fits inside.  A hard cover for the 
front of the K2 would be a nice option, just as it would be for the 
other Elecraft rigs.


The K3 does not fit.

Re: [Elecraft] K3 2 tone 3rd order dynamic range at 2 KHz tone spacing

2007-12-27 Thread Toby Deinhardt

Hi Dave,

My K3 shows an IMDR3 of between 110dB and 105dB with slight variations 
from the upper to lower side. This with the 400Hz roofing filter and 
400Hz DSP filter at spacings of 100, 50, 20, 15, 10, 5 and 2kHz on the 
20m band. Last week our quick and dirty first look also gave us numbers 
in the same ballpark: IMDR3 of 106db at 20 and 5kHz and 104db at a 
spacing of 2kHz.


We did find some spurs, last week, which were coming from one of the HP 
signal generators, which slightly confused us at first. The spurs were 
very far down, but they were there.

Sarah,
I'm pleased that you took the time to stop in Gaviota and snap a few photos  
of the rest stop as well. 
I live a few miles down the road toward Santa Barbara.  The dead trees  you 
saw are more of a bush when foliated and were actually the remains of a burn  
that swept through the area about 3 years ago. The protracted draught in this  
area has delayed the usual re-growth considerably. This area is noted for its  
daily high winds and that contributes somewhat to the vulnerability to fires. 
I  hope you had a chance to turn towards the beach area a 1/4 milesouth 
and have a look at one of the nicest beaches on the Cal  coast. know  for a 
very wide expanse of pure white sand I have spent quite a few days as a  
youngster playing there.
 
The shot up hill at the ridge on the west side has a very interesting  
feature we cal the 'elephant'. It's most noticeable when in the southbound 101  
as 
you approach from the canyon. along the ridgeback is a formation of rocks  that 
look like a small family of elephants - mom,  pop, and a couple young,  as 
they trudge up the ridge tail in trunk with the lead elephants trunk/head and  
right ear very pronounced. Mostly only locals who travel the road frequently 
are  aware of it.
 
Hope the rest of trip was fun and love the K2!

I got a letter in the post, rang the enclosed phone# to pay NZ$381 GST etc
and had it on my desk at the saltmine the next morning.
The hardest part was looking at it all day at work!!.

It went together a treat and works well.
Be VERY carefull to completely read and understand the construction manual
as I had a problem setting up and callibrating the rig but after a cople of

Enjoy the rig and give us shout if you need help or want a K3 to K3 qso!!

I just received the Heil Proset from Elecraft.  When my K3 arrives I plan to 
use the headset with the K3.  Since I expect a rather long wait until my K3 
arrives I am wondering if the headset can be used with my current TS-940 
radio.  The earphones work but I don't want to try the microphone until I am 
sure it is compatible with the 940.  The mike plug is physically proper but 
I can't find a wiring diagram for the headset so I'm not sure about the 
electrical correctness.  If the wiring is not a match can I wire up a simple 
interface or isn't that practical?

keying via the mic's PTT line. My Heil connects to the front of the 
RigBlaster.
Audio from the K2's speaker jack goes to the RigBlaster (and then to the 
PC).

[Elecraft] Mountain Ops Tac Pac replacement?

2007-12-27 Thread Christopher A. Kantarjiev
I've been moving my K2 around a bunch over the past few months, and find myself 
wishing that I had a decent fitted bag for it (I end up wrapping it in bubble 
wrap). I've heard about the TacPac, I know that they're no longer made (despite 
assurances that the company was being sold to someone who would carry on).


Do you have a favorite bag for carrying your K2 and a few accessories (like a 
set of Palm Mini paddles and some cable, maybe a small PS)? I need something 
that will protect it in the car, not from airline luggage gorillas.


The Western Pack case shown at 
http://westerncasecompany.com/html/camerabags.html - the small "Weekender" - 
seems about the right size, but perhaps somewhat too big.

Re: [Elecraft] K3 - A CW rig?

2007-12-27 Thread w6jd
Fred,

I am a devote CW op and have never enjoyed SSB until the
K3 came along. K3 audio is remarkably clean, distortion
free and a joy to listen to. Clearly a great deal of the "trash"
I heard on SSB I should have attributed to my receiver rather
than the "other guy". Unlike many other implementations, the
K3 DSP noise reduction is very effective without introducing
annoying artifacts. At its most aggressive it will produce a
hollow, "bottom of the well", sound but with no loss of
intelligibility. The VOX is the smoothest I've ever used and
is all you could ever want. Being able to tailor both the
receive and transmit audio allows you to compensate for
your voice and hearing characteristics quite effectively.

Re: [Elecraft] xv222 - Diode Issue - CORRECTION

2007-12-27 Thread John Hoaglun
Hi Eric,

The printing on the diode is not real crisp.  It looks like 1N5  then
358.Is possible that 2 and 8/B (the last position on both lines
respectively) has a bad silkscreen?  The 8 could be either an 8 or a B
very easily. I talked to Scott last Friday and asked him to ship me a
new D3 and L15. I hope that they will arrive today or tomorrow.

Bottom line... the part in question was not clear. Support is sending
me a replacement to make sure that we are 100% certain on the part.
The support from the Elecraft has been great so this is NOT a big deal
in my book.

Thanks, JH

It would be my guess that it is R19, associated with the front panel assembly.  
R19 is a 100k-ohm resistor that was added *after* the first few hundred K1s to 
improve the linearity of the VFO tuning.  It will be soldered across two of the 
terminals of the VFO potentiometer, so it will not actually be installed on any 
of the K1's PC boards.

My K1 was one of the first (#175), so I don't know how K1 kits 2500 units later 
are being packaged.  I may be wrong.

Re: [Elecraft] How to clear your K3 through New Zealand Customs

2007-12-27 Thread Ross

Hi all,
Phils,
comments are only partially correct.
Normally NZ Post will send a letter saying a parcel has arrived and how to 
pay for any GST.
However the best way is to have an account with a Customs agent or with UPS 
and or Fedex

and then there are no problems at all.
For example I had a parcel from M2 yesterday that came Fedex, they cleared 
it, and sent it

on by courier.
Bureacracy doesn't get involved.

Re: [Elecraft] K3 and spectrogram: dual passband

2007-12-27 Thread Lyle Johnson

The outer PB is tipped, that is, the high frequency side of
the inner filter is five to ten DB stronger than the low side.
 Seems like it ought to be in balance.


I think if you plot the response at whatever width you have set, you'll 
see the low frequency rolloff before you engage Dual PB.  This is likely 
due to the relationship of the filter skirts and BFO.  If you then turn 
on Dual PB, you'll see the former passband suppressed about 25 dB and 
the 150 Hz wide peak rising above it.


Alternately, set the pitch higher to get away from the wide filter's 
passband edge and you'll see the suppression is in fact symmetrical 
about the peak.

[Elecraft] K3 2 tone 3rd order dynamic range at 2 KHz tone spacing

2007-12-27 Thread Dave G4AON
I've been looking at the performance of my K3 using a buffered fixed 
crystal oscillator, hybrid coupler and Marconi 2018 signal generator... 
I've noticed a strange phenomenon where the two tone dynamic range 
appears to be approximately 10 dB worse at 2 KHz spacing with the 400 Hz 
8 pole filter than with the 2.8 KHz 8 pole filter (90 dB and 100 dB 
respectively). At 5 KHz the range is 100 dB with either filter. Altering 
the width control from 400 Hz to 450 Hz and back again switches the 
filters, the audible effect of the spurious signal being there or not, 
is quite striking. Both upper and lower 3rd order products behave the 
same, I also get the same results with the Marconi signal generator on 
the high side or low side of the crystal oscillator.


Anyone with a pair of signal generators and a hybrid coupler care to 
check their K3 and see if they obtain the same results? I'm assuming the 
reason is ripples in the passband of the 400 Hz filter many dBs down the 
passband.

Re: [Elecraft] K3 Filter advice...

2007-12-27 Thread drewko1
Thanks to everyone for their comments on filters for a CW+AM K3. They
are very helpful. 

I was aware of the distinction between roofing filter and DSP
filtering but didn't know (or forgot) about the 2.7 kHz standard
filter.  

As for the "hoped for" multi-bandwidth filter, I guess it is probably
too soon to talk about. My first questions would be how wide it would
go and how much it would cost.

[Elecraft] K2 #6099 is Alive!

2007-12-27 Thread geoff allsup
I finally completed K2 #6099 early on Christmas Eve.  So far, just the basic CW QRP version; have 
the K160RX option to build yet.  Construction was smooth through all stages.  Receiver sounds 
fantastic, filtering is great (just used the setup described in the manual)!  With the whirlwind of 
Christmas and grandkids, I've only had a little time to read over the operations section of the 
manual.  Can't wait to get some free time on the air for a first contact - tonight looks promising!

Now, what option do I want next!?!?

Thanks, Elecraft!

[Elecraft] Amplifier Hook Up

2007-12-27 Thread Dave G4AON

J15 (phono) is the keying output... it connects to the drain of Q3 and keys a 
linear...

73 Dave, G4AON

That PTT RCA socket is an INPUT - to close the PTT line  - ie it puts the K3
into transmit.

[Elecraft] How to clear your K3 through New Zealand Customs

2007-12-27 Thread Phil Holliday
I was delighted to receive my K3 s/n 138 here in the Land of the Long White
Cloud recently.  Here are some notes for anyone else in ZL who is waiting
for their shipment to clear NZ Customs.

 

The K3 was shipped from Aptos on Dec 5th and arrived into Customs here 2
days later.I was tracking its progress thru the USPS website.  There was
no progress.  Having phoned and been informed that I would receive a letter
giving me details of tax to pay I waited, but there was no letter.  I
finally phoned NZ Post who gave me a number in NZ Customs to call.  They
denied all responsibility for clearing the shipment and said it was the
responsibility of NZ Post.  Back to NZ post who were surprisingly helpful,
told me that this happens all the time, Customs deny all responsibility etc.
After some time on the phone from a really helpful customer service rep he
gave me an Entry Number which is the one piece of information you really
need, plus a  customs phone number to call.  Within 3 minutes I had given
them my credit card number to pay the tax, they had cleared the package and
it arrived the next day, 14 days after arriving in the country.  For all
other ZLs patiently waiting out there I hope this is of some help.  Now for
the best part.

 

Phil, zl3pah
