Re: [Elecraft] K3S - have initial shipments begun?

2015-06-24 Thread Charlie T, K3ICH
What's the best way to check on the status of a
previously placed order?

Specifically, I ordered a new K3S about 6 weeks
ago via internet and have not received any sort of
confirmation.

I'm suspecting I may have screwed up the order and
it never went through (gasp!)

I know they're are really busy, so I don't want to
add to the confusion by pestering, but I AM
getting a little concerned.

I am at my shack machine now. I decided that while I still 
had the antennae disconnected, I would scan the 6M band for 
birdies. Bandwidth set at the usual CW mode, 400 Hz, tuning 
from the bottom of the band upwards.


Preamp is OFF unless otherwise indicated.

_CW - 400kc filter_
50.195.25 S1 - No reading on S meter preamp Off. S1 
just flickering with External Preamp(PR6) ON

Nothing else heard up to at least 50.300

_Now opening up the bandwidth to 1 Kc (1.8kc filter engaged)..._

50.152.14 VERY weak
50.195.89  S1 but stronger than previous one
50.198.12 VERY Weak
50.240.58 VERY VERY Weak... even with preamp ON
50.278.22 VERY weak
Stopped at 50.300

_Opening bandwidth up to 2.8 kc__  (I have the 8 pole 2.8kc

The strongest birdie I am experiencing here is with CW mode, 
2.8kc filter and  preamp off. I reconnected the 6M beam and 
the strength of the birdies is unchanged. That strong 
birdie is at 50.115.35 or so, S2 with no preamp,and S3-4 
with external preamp ON.


When I installed the new KSYN3A boards, I took no special 
precautions on dressing the TMP cables other than trying to 
approximate the routing shown in the instructions.


I reconnected my beam and spot checked a few data points and 
the birdies are still present and the same relative 
strengths. The only one that might cause me some distress is 
the one at abt 50.115, and I can remove that with the firmware.

Subject: Re: [Elecraft] K3 Reports of intermit bad
audio

I keep getting private e-mail asking what were the
symptoms and what fixed the problem.
The radio was shipped back to me after a trip to
the factory for an upgrade and repair. 
The radio came back and once it was hooked up, I
joined a group of people that I talk to all the
time. 
Everyone said that my audio did not sound right.
The intermittently it would go from just okay to
terrible. I had one of the guys I talk with watch
me on his pan adaptor and it showed spikes and a
very dirty signal. I contacted Elecraft by e-mail
on the weekend and first thing Monday Morning
Howard from Elecraft had called me and left
message for me to return his call. I returned his
call and he walked me though all of my settings.
Then after everything checked out he said that he
had see something similar to this and explained
what he thought it might be. Howard told me that
if I removed the fans and circuit breaker panel
off of the back side I would be able to see where
the amp connected in. Howard e-mailed me two
pictures one the correct way and the other was one
they had found the caused a similar problem. I
pulled the plate off of my radio and sure enough
the amplifier was not seated all the way down in
the connector. I pushed down on the amp board and
it seated completely with the connecting board. I
then loosened all the screws on both the board and
the amp and made sure they were seated and then
retightened the screws. My K3 is now functioning
great. I don't know how it came loose, but it did.
It could have been loosened and moved during
shipping, I do not know. I took a picture of the
connector before I secured it, but I do not know
how to post a picture of it here. 
Okay hope this answers everyone's questions and
hopefully if someone ever has these symptoms and
research the forum they will be helped by this
too.

[Elecraft] CW filter and Roofing filter

2015-06-24 Thread Gee
Trying to sort this out... 
1) with any filter selected using the XFIL button on the K3, there is only ONE 
crystal IF filter in the signal path. In other words, there is no cascading or 
tail ending of the filters before and after the IF.
2) if I select a 400 Hz filter with the XFIL button then adjusting the DSP 
WIDTH control to any WIDER than 500 Hz is pointless.
3) can the DSP be bypassed to produce a purely analog demodulated audio to the 
speaker? As I recall years ago, some early DSP radios had this feature. I am 
pretty sure the answer is no but still, had to ask.
It is interesting to note that there are new hams out there who have never 
listened to an analog receiver before. It can be an eye opening experience!

Re: [Elecraft] CW filter and Roofing filter

2015-06-24 Thread Arie Kleingeld PA3A

Cascading:
The only cascading filtering is first the xtal filter and then the DSP 
filter. (So there's only one xtal filter)


400Hz-500Hz:
Yes listening to a wider DSP filter than Xtal filter is pointless. 
Although (if configured correctly) the K3 will switch to a wider Xtal 
filter (if there is one) if you widen up the DSP.


Analog demodulation:
Demodulation in the K3 is DSP. There is not menu setting to get around this.

Re: [Elecraft] CW filter and Roofing filter

2015-06-24 Thread Don Wilhelm

Gee,

The K3 DSP cannot be bypassed, it is part and parcel of the K3.  The DSP 
mathematical computations are what does the modulation, demodulation, 
and forms the filters as well as doing a lot of other tasks.  The K3 DSP 
processing in the K3 is done at a frequency of 15kHz.
There is no parallel to an analog receiver.  The front end of the K3 is 
analog, but as soon as the signal is converted to 15kHz, it goes through 
an ADC and becomes 'mathematical soup' - after processing, the math 
result is fed to a DAC where it emerges as audio.  In other words, the 
K3 is an SDR with an analog front end and a built-in processor.


The K3 must have the 2.7 or 2.8kHz filter installed.
If you have additional hardware filters installed, they are not cascaded 
- BUT the roofing filter can cascade with the DSP filter. Even if you 
select a narrow filter with the XFIL button, if you widen the DSP 
bandwidth beyond the width of that narrow filter, the K3 will switch to 
a wider filter.


I hope that helps your understanding.

Don W3FPR

Correct

Semi-correct.  If by filter you mean crystal roofing filter, and if by 
IF you mean 1st IF [8 MHz], correct.  One roofing filter followed by 2nd 
IF filtering provided by the DSP.


 2) if I select a 400 Hz filter

Sort of.  The K3 will automatically select a roofing filter from 
whatever you have that is wider than what the DSP is set to ... if it can.


 3) can the DSP be bypassed to produce

a purely analog demodulated audio to the speaker?


No.  Once the 15 KHz 2nd IF becomes number soup in the DSP, there are 
only two analog things left in the chain:  The AF amplifier and you. 
The DSP contains a lot more than just adjustable filtering, such as AGC 
and demodulation.



It is interesting to note that
there are new hams out there who have never listened to an analog
receiver before.


True

It can be an eye opening experience!

Possibly, although I doubt most would find that.

[Elecraft] KBPF3 upgrade kit and instructions now available

2015-06-24 Thread Wayne Burdick
Hi all,

The long-promised KBPF3 modification kit is now available. It applies to the 
KBPF3, K3 RF board, and optionally to the KRX3 sub receiver. It allows the K3 
or K3S to receive signals in the 100-500 kHz range with good sensitivity. This 
is an interesting part of the spectrum, with 

For full details on the mod kit, see:

   http://www.elecraft.com/order_form_parts.htm#K3%20Parts

Also see below for an excerpt from my original posting about signals in the 
100-500 kHz range.

73,
Wayne
N6KR


* * *

In honor of the FCC's proposed 2200 meter allocation (137 kHz), we decided to 
see if we could improve the K3's receive sensitivity in the 100-500 kHz range. 
This extended coverage is made possible by the new synth (KSYN3A). 

After a lot of digging, we discovered the cause of the wide-band low-frequency 
noise. We also found a way to shift the passband of the KBPF3 lower. 

With a couple of simple modifications, the MDS (minimum discernible signal) can 
be improved by about 25 dB at the low end (100 kHz). Here are some test results 
(preamp off, 400-Hz bandwidth): 

137 kHz -114 dBm FCC's proposed 2200 meter band
160 kHz -117 dBm low end of the Low-Fer band
250 kHz -126 dBm test frequency in the long-wave beacon band
472 kHz -133 dBm 630 meter experimental band

This represents an improvement throughout the range, but especially at the low 
end. I believe -114 dBm MDS should suffice at 137 kHz, given the high band 
noise in this range. 

Another indication of how well the mods work: With no antenna connoted, the 
K3's S-meter now just barely flickers (S1) at 100 kHz. Without the mods, the 
no-antenna S-meter reading could be as high as S7 due to the noise source we've 
now identified (a voltage regulator). (By the way, this regulator noise had no 
impact on frequencies about about 500 kHz.)

[Elecraft] [K3] ideas for re-purposing our old K3 synthesizers

2015-06-24 Thread inventor61 .
I printed out the schematic of the original K3 synthesizer module.  The
diagram says 'rev. A4' and is dated 8 Jan 2010.  Hope that's close to the
as-built!  (probably is)

This gizmo appears to have an output range from 8.7 to 46 MHz.  I don't
know how much sauce it can develop but I have to imagine +10 dBm or so into
50 ohms, I bet it's flat across that range, and it looks like the thing
would be whistle-clean.

To get that, it needs a tight 49.38 MHz reference oscillator (I found a
0.5PPM TCXO for ~$30 from mainland China), and several common DC supply
voltages.

It also needs a small microcontroller or other way of providing the correct
serial peripheral interface command lines and interaction.  That processor
would also control the output frequency, perhaps with an encoder, or
whatever human interface might make sense.

But first, I am trying to see if developing a 'host' PCB would even be
fiscally wise to design and construct.  I mean, who needs a 8.7 to 46 MHz
VFO?

And, how mad would Eric or Wayne be with me about the ... um ...
semi-inverse engineering research ... I'd have to do to make this thing
operate?

On the other hand, I wager there's a thousand-plus of these modules sitting
around the planet looking for something to do.  The capitalist in me is
intrigued.

So, a bit of market investigation here:

a)  what would you do with such a device if you had one?  bench signal
generator?  beacon transmitter?  VFO for another radio?

b)  would you pay, say, $100 for a host board to operate your now-surplus
synthesizer?

c)  if someone *else *needed YOUR spare module for THEIR project, what
would you be willing to sell it to them for?  Free?  $25?  More?

Also see below for an excerpt from my original posting about signals in the 
100-500 kHz range.

N6KR


* * *

In honor of the FCC's proposed 2200 meter allocation (137 kHz), we decided to 
see if we could improve the K3's receive sensitivity in the 100-500 kHz range. This 
extended coverage is made possible by the new synth (KSYN3A).

After a lot of digging, we discovered the cause of the wide-band low-frequency 
noise. We also found a way to shift the passband of the KBPF3 lower.

With a couple of simple modifications, the MDS (minimum discernible signal) can 
be improved by about 25 dB at the low end (100 kHz). Here are some test results 
(preamp off, 400-Hz bandwidth):

137 kHz -114 dBm FCC's proposed 2200 meter band
160 kHz -117 dBm low end of the Low-Fer band
250 kHz -126 dBm test frequency in the long-wave beacon band
472 kHz -133 dBm 630 meter experimental band

This represents an improvement throughout the range, but especially at the low 
end. I believe -114 dBm MDS should suffice at 137 kHz, given the high band 
noise in this range.

Another indication of how well the mods work: With no antenna connoted, the 
K3's S-meter now just barely flickers (S1) at 100 kHz. Without the mods, the 
no-antenna S-meter reading could be as high as S7 due to the noise source we've 
now identified (a voltage regulator). (By the way, this regulator noise had no 
impact on frequencies about about 500 kHz.)

I have used USPS to ship to UK, EU, and AUS on several occasions and it 
all went well.  Just keep in mind that local postal and/or customs may 
hold the item for a few days before even notifying the recipient that it 
has arrived.


Some places do not charge the recipient a VAT on Amateur Radio 
gear...it's a good idea to check before sending.

Re: [Elecraft] [K3] ideas for re-purposing our old K3 synthesizers

2015-06-24 Thread Wayne Burdick
Hi Steve,

Not to throw cold water on this, but the original KSYN3 requires a ton of 
firmware support, including a hand-tweaked table of thousands of PLL divider 
values pre-calculated and stored in flash memory. We shoehorn the DDS reference 
signal through a 3-kHz wide crystal filter in order to ensure no close-in 
spurs, then adjust the PLL divider values in real time so there are no gaps in 
the tuning range despite a nominal 20-kHz PLL step size. Lots of idiosyncratic 
math, and a critical calibration step (VCO CAL). 

So if each of your repurposed KSYN3s comes with a K3 front panel MCU and flash, 
no problem :)

Wayne

Correct.  With the K3, you can have a paddle, bug and straight key all

Megawatt unit, this one is Coldfusion.  Like the Megawatt, very little RFI. 
This one has the thermal sensing on the fan.

Hi,

try this one:
http://www.repeater-builder.com/other-mfrs/megawatt-ps/megawatt-ps.html
http://www.12voltpowersupplies.us/

Even although I am using always linear PSUs for powering my radios I tested
some time ago this unit and it was noiseless and quiet. Also You can find
several good user reports so it sounds like good solution.

You should stay away from offshore clones only...

Hope it helps,
73 - Petr, OK1RP

Re: [Elecraft] K3 Reports of intermit bad audio

Howard told me that if I removed the
fans and circuit breaker panel off of the back side I would be able to see
where the amp connected in. Howard e-mailed me two pictures one the correct
way and the other was one they had found the caused a similar problem. I
pulled the plate off of my radio and sure enough the amplifier was not
seated all the way down in the connector. I pushed down on the amp board and
it seated completely with the connecting board. I then loosened all the
screws on both the board and the amp and made sure they were seated and then
retightened the screws. My K3 is now functioning great.

Thank you Howard, Wayne, and Eric for your outstanding customer service.
All is great with my K3 now.
It still amazes me and it floored a couple of other hams that were 
here in
my shack when Wayne returned my e-mail. They were like  That is one 
of the
owners, I was like yeah. They could not believe that a simple guy 
like me
could get one of the owners to e-mail me back. I laughed and told 
them that
I had exchanged e-mails with both owners and had even spoken to them 
on the

phone.
One of the hams laughed and said yeah try that with any of the big 
three.
Then said he believed he was going to sell his radio and purchase a 
new K3.
I explained the new K3s to him and told him he would not miss the old 
radio.

Got off subject here sorry.
Thanks again Elecraft for the outstanding Customer Service.
Thank you
