Re: [Elecraft] K3 Squelch

2009-03-24 Thread David Woolley (E.L)
The article that was claimed to be unreadable was a top posted article 
quoting a top posted article.  Top posting was not an issue here.  The 
actual issue, was that, at least in the digest, a number of articles 
were posted with Content-Type: text/plain headers, but containing 
invalid HTML, which, on any reasonably compliant email program display 
as raw HTML.

However Don's real issue seems to have been with people who fail to trim 
properly.  Top posting almost guarantees that people will fail to prune, 
  which is one of the reasons why the digests are so large. If you have 
to exit after each email or terminate reading by deleting, top postings 
hides this problem.  If you are reading the digest, or have an email 
reader that pages across message boundaries, failure to prune forces one 
to wade through the whole back thread and, particular in digests, can 
make it difficult to find the next thread.  IE's attach original mode is 
even worse, as Thunderbird displays the attached message as though it 
were an independent article, so one has to look very carefully to find 
the next real article.

Incidentally, I consider email posted with only HTML to be a strong spam 
indicator and all postings with HTML variants to be newbie indicators. 
They also contribute to the high number of bytes on this list.

For once, I am  deliberately posting this badly, quoting the entire back 
thread including footers added by the reflector.  Unfortunately, as I'm 
replying from a MIME digest, I can't add a copy of the footers added on 
the way out to me.

 I agree - If I do not find something relevant in the first few lines of 
 the post, I usually delete it.
 If you can surmise from that comment that *top posting* is important to 
 me on an email reflector with as much traffic as we have here, then you 
 are correct - I just don't have the available time nor patience to 
 scroll down through a posting to find what has been added.  By the same 
 token, in-line additions may sometimes be warranted, but I believe that 
 should be the exception.
 The netiquite' stuff may be important in other discussions, but for 
 what we are dealing with here, top posting is my preference.  Note that 
 Eric says either is OK, so I am expressing my personal opinion.

Doing so only acts as a roofing filter.  With a good enough sound card 
and good enough algorithms, the terminal program ought to be able to 
eliminate the interference as well as using a narrow filter in the K3 DSP.

If the sound card is adding IMD products or the terminal program isn't 
designed to detect the signal in the presence of noise, you may benefit 
from using the K3 DSP as a roofing filter.

Yes, definitely, unequivocally. (To use the vernacular: youbetcha :) I can't 
give you any

[Elecraft] K2: The Dog Ate My Part

Oh, that is tooo funny.  I've had 3 labs.  It's a good thing God made them cute 
because they sure are stupid! (said in loving jest).

Actually, you might have been better off if she HAD swallowed it.  Dogs don't 
chew.  You could have just waited a day or so and retrieved it from the yard 
and it would have had no chew marks.  I'm sure she'd have delivered her package 
faster than the replacement would arrive through UPS.  UPS will put the package 
on the front porch though.  If your dog did that, she'd probably hear bad dog.

[Elecraft] K3 Timekeeper

The baud rate is automatically changed to 38400 baud during firmware download 
and is restored to the selected value in CONFIG.  I had my baud rate set at 
4800b.  The Timekeeper program apparently is too fast for the K3 to change to 
3800 baud.  I changed CONFIG: RS232 to 3800b and Timekeeper works fine now.

Re: [Elecraft] K2: The Dog Ate My Part

2009-03-24 Thread Ron D'Eau Claire
Ha, ha! Jon, you might want to save that well chewed I.C.

As a 10 year old kid fascinated by radio, my sable collie decided to taste
the binding of my prized, hardbound ARRL handbook - my first radio book
that I read so often I can almost recite whole paragraphs today. 

He made a pretty mess of one corner, chewing through the cover into the glue
along the spine. 

I patched it up with some cellophane tape and probably glared at him a lot
for a long time, but he was my best bud throughout my teenage years. He
died a decade later while I was away in the Army.

Half a century later I still have that book sitting on the shelf, and every
time I see or hold it I remember my old friend.

Re: [Elecraft] K3 and PSK31 Data Mode and ESSB

Doing so only acts as a roofing filter.  With a good enough sound card

eliminate the interference as well as using a narrow filter in the K3 DSP.

I disagree, for two reasons. 

1) IDEALLY, the soundcard should be good enough to reject interfering 
SIGNALS, but computer sound cards are notoriously poor. Thus, a good 
roofing filter for the sound card (in the form of a narrow IF, and even a 
good audio filter) is a very good thing. 

2) Noise that appears anywhere in the passband is broadband in the audio 
spectrum, and raises the overall noise level at the sound card. When we 
improve that signal to noise ratio without degrading the magnitude and 
phase response for the desired signal, the soundcard has a better chance of 
decoding a weak signal.

[Elecraft] K3 digital mode audio input via LINE IN

I can't get the K3 to transmit using audio supplied to the LINE IN jack. I'm
working in DATA A mode. I CAN transmit with audio supplied to both the
front- and rear-panel MIC jacks. I have tried selecting the main MENU MIC

Re: [Elecraft] K2 standard mic input = kenwood circuit - - what mic do you recommend?

2009-03-24 Thread Don Wilhelm
Duane,
 - that is not quite correct.
The K2 has a microphone configuration header which can be wired for many 
microphone pinouts.
If all the pins are jumpered straight across, it will be the Elecraft 
microphone pinout at the microphone jack.

The Elecraft mic pinout is *not* equal to Kenwood - it differs on pins 5 
and 6.  However, if the Kenwood microphone is of the unamplified dynamic 
type, it will not use pins 5 and 6 and will work fine with the K2 
straight across plugging of the mic configuration header.  That is 
what compatibilty means - most popular Kenwood mics will work, but not 
*all* Kenwood mics.

The K2 microphone pinout can be wired to use just about any common 
amateur microphone.  The instructions are in the KSB2 manual.

Note: the K3 has a fixed microphone pinout - it is the Elecraft pinout, 
no microhone configuration header in the K3.

Ken,

Not heard here, but I find a very weak signal on 10106.75.  Since it 
gets very weak when I remove the antenna - and is very strong if I just 
use a wire to the antenna jack center conductor, it is something in the 
shack (my antennas are more than 100 feet away).  I suspect something 
associated with the Ethernet cabling in the house, but I am not going to 
shut it down to check.

The 'fast-tuning birdie removal tool' will not work on real signals 
(those do not 'fast-tune').

[Elecraft] [KX1]Output Power Measurement

2009-03-24 Thread Ron Bower
I have searched the archives and have not been able to find a definitive
answer.

 

I've now completed the construction of the basic KX1 and would like to have
a fairly reasonable measurement of the output power on 20M and 40M

 

I have a very decent dummy load but do not have a very accurate RF Power
meter. I do have a decent DMM and could measure the voltage drop across the
50 ohm dummy load - I'm not sure how accurate the DMM would be at 7 or 14
MHZ.

 

Is there a recommended method to measure the power output without an RF
power meter ?

 

Thanks in advance,

Ron, AC2C

Re: [Elecraft] [KX1]Output Power Measurement

2009-03-24 Thread Jack Smith
You might use a diode, such as a 1N914, 1N4148 or (preferably) a 1N5711 
to rectify the voltage developed across the load and then measure the DC 
out of the diode. With a high Z load such as a DMM,  the DC voltage will 
be close to the RF peak voltage.

A standard DMM, even a good one, will not provide usable results above a 
few hundred KHz, unless it's a specialized instrument intended for RF 
measurements.

Use a diode detector.  A 1N4148 diode will do fine up to about 12 watts.
Connect the anode of the diode to the center conductor of your coax *at* 
the dummy load (use a coax TEE adapter if you have no other access).
 From the cathode end of your diode, connect a 0.01 uF capacitor to the 
shield side of the coax.
Your DMM leads connect across the capacitor.

Measure the forward voltage of the diode with your DMM if it has that 
function, otherwise, assume that the diode forward voltage is 0.6 volts.

With this probe, the DVM will read the peak RF voltage.  You can 
calculate the power from the DMM reading as follows:

The peak voltage across the resistor is equal to the DVM reading plus 
the diode forward voltage, so add them.
You may then calculate the RMS value of the result above.
Then square that result and divide by the resistance.

Or you may accept (or derive) the formula will be as follows with no 
intermittent RMS calculation.
P = (Vdvm+Vdiode)^2/2R = (Vdvm+Vdiode^2/100 for a 50 ohm dummy load
OR, if you assume the diode drop is 0.6 volts
P=(Vdvm+0.6)^2/100

 I have a very decent dummy load but do not have a very accurate RF Power

 50 ohm dummy load - I'm not sure how accurate the DMM would be at 7 or 14
 MHZ.

  

 Is there a recommended method to measure the power output without an RF

Re: [Elecraft] [KX1]Output Power Measurement

2009-03-24 Thread Jack Regan
Ron,

I just went through this scenario. With the help of Don Wilhelm I was able
accurately measure my power out on my KX1 and K3.

I first used a homebrew load with free resistors given away at a club
meeting. They only worked at low frequencies. At 20 meters the SWR to far
off to be of use!

I bought an Elecraft DL1 because it uses one of the correct types of
resistors for this application and it has a built in VDC test point!

The only thing to be wary of is that the DL1 test point is at the 25 ohm
point in the series of resistors!!!


Don's formula (and mine) differs from that found in the DL1 manual.

Elecraft:

P(in watts) = ((Volts * 1.414) +(.15))^2 / 50

Don:

P(in watts) = ((Volts) + (diode drop))^2 / 25

Jack:

P(in watts) = (((Volts) + (diode drop) * 2)) / (square root of 2)))^2 / 50


There are 3 points to be aware of. 
1. Use the square root of 2 and not the 1.414 figure.
2. Measure your diode drop.
3. Combine the drop with the VDC before doing any other calculations.
4. If you do not use Don's formula, DIVIDE by the square root of 2.

The Schottky diode in my DL1 measures .330 mv.

A 1N34a (germanium diode) has a drop of about .3 volts. A Schottky's drop
is a little more but offers more linearity!

In any case, the VDC voltage must be divided by the square root of 2 to get
the RMS. In other words the VDC(0-Peak) is 1.414(approximately) times the
RMS voltage

If you measure the VDC at the 50 ohm point then my formula becomes:

 P(in watts) = ((VDC + (diode drop)) / (square root of 2))^2 /50

After getting an accurate measurement of my KX1's power I found that the KX1
ATU was showing values that were too high. By adjusting C9 and R1 I was able
to get the KX1 and the DL1 to agree!

BTW, I also used the DL1 to calibrate my K3 at low power. Now the K3, my DL1
and my Versa Tuner V all agree!

[Elecraft] Remot control of K3

2009-03-24 Thread dbevan
I have a 150 mile drive each way from my home to my QTH 
and I need a full remote control solution. Operate mostly 
CW, serious DX primarily 160M, and some contests. Only 
have POTS phone lines so no brodband connection yet. Does 
anyone out there know of someone successfully doing this? 
I'm not a computer geek so keep it simple.

I think there was an article relevant to your situation in one of the last ARRL 
contest journal.

Re: [Elecraft] K2: The Dog Ate My Part

 How embarrassing is this?
  
 As I was working on the KPA100 last night, the EL5146CN op-amp (a small 8-pin 
 IC) slipped out of my fingers and fell to the floor - right in front of the 
 idiot lab/pit mix who promptly decided to taste it.  She didn't swallow it 
 (fortunately), but it's well chewed and I have to order a replacement from 
 Elecraft.
  
 Why me?
