[Elecraft] Elecraft CW Net Announcement

[kevinr]

Good Evening,
   I spent a few hours today cutting, hauling, splitting, and stacking 
wood.  Now I am trying to stay awake :)  The weather was perfect for 
this kind of work: sunny and not too warm.  Once I got moving I no 
longer needed a jacket.  A little while later my sweatshirt was soaked 
through.  When I came into the house and sat down I got a chance to 
drink some water.  The next thing I knew it was an hour later.


   Propagation has been pretty goodthis week with a little QSB flutter. 
The sun has been active enough to give us decent conditions without a 
large amount of noise. Twenty, thirty, and forty meters all seemed 
pretty good.  The first net should not interfere with anything major but 
the second is right in the middle of a football game.  I'll call it and 
see who I can find.


Please join us tomorrow afternoon and evening.

1) Hail signs  (first letter or two of the suffix of your call)
2) NCS help  (as well as QSP/QNP  help)

Sunday 2300z (Sunday 3 PM PST) 14050 kHz
Monday 0200z (Sunday 6 PM PST)  7045 kHz

   Stay warm,
  Kevin.  KD5ONS

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

While you sleep on it, think back to whatever caused he R30 voltage to 
go to high ( 8+ volts).  That is the key to whatever is happening.


I am also calling i quits for the night - have a good rest.

[stan levandowski]

In some ways, a "better" time...but only those of us who were there can 
really appreciate it because it's more about context rather than 
electronics.   73, Stan WB2LQF

Re: [Elecraft] K3: vs a Collins S-line RX

[Don Wilhelm]

Phil,

Buy a K3 with KBP3 option or a KX3, but don't put it into Transmit - you 
will have a superb general coverage receiver.
If you are looking for a lower cost because the transmit capability is 
not present - I would say "probably not".

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

Since you now have 8 volts at the left end of R30, I would wait and see 
if you can get all the band end R30 voltages into spec with adjustment 
of L30 and the turns spacing of T5.  If so, I would ignore the DC 
voltages at U4 pins 1 and 2.  Those voltages are partially a result of 
just where within the 10 kHz range of the PLL reference oscillator it 
happens to be.


I am glad to hear that you now have it working within a reasonable range 
- good work.

Thanks Don,

I'll rewind T5 and see where that gets me.

U4 pins 1 and 2 are still low (no change), and U7 pin2 and U4 pin5 are
equal.  Do you still suspect there may be an issue with U4?

Re: [Elecraft] K3: vs a Collins S-line RX

[Jim Lowman]

I finally decided to buy the general coverage bandpass module for the K3.
Pretty cheap, when you consider the cost of a good receiver.
I recently rediscovered the thing that got me interested in ham radio - SWL.

Of course, if you're talking about a receiver for the ham bands only, I 
love my Drake 2-B and R-4C.

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

You are making progress.
That is a good indication that you have resolved the problem.
Yes, add back turn 16 of T5 and things should come into normal.

Hint - you may still have to spread/compress the T5 windings, but as an 
aide to know which is to be done, tune down from 4000 kHz to where the 
voltage at R30 drops below 8 volts.  Then adjust the turns on T5 to 
reduce the voltage, then re-check 4000 and repeat as necessary.


You will find the maximum voltage will be your 8.04 volts, and you will 
have to change T5 (or readjust L30) to reduce it.  You will not be able 
to see which way to go (compress or spread the T5 turns) with the R30 
voltage at 8 volts, reduce the frequency and then it will become 
apparent whether spreading the turns or compressing them will reduce the 
voltage.  In other words, 'sneak up an getting the 4000 MHz voltage to 
6.00 volts.


Once you have 4000 MHz voltage at 6.00 volts, check the low and high end 
of all other bands.  You may have to make compromises to get all of them 
in range - the 6.00 volts at 4000 kHz is not a hard and fast number, it 
is just a target that usually works.

R30 is now showing 8.04V, but 40M is reading in the 13000khz range, with L30
able to adjust frequency but not voltage.

I'm thinking I may need to add back in the turn that was removed from T5
earlier to bring everything into spec?

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

The DC voltages at U4 pins 1 and 2 are suspicious.  The voltage at pin 5 
is from the MCU digital outputs, so I would not be to concerned about it 
just yet.  However, compare the voltage at U4 pin 5 with the voltage at 
U7 pin 2 - that is the same signal, and the voltages should be the 
same.  If they are not, then there is a connection problem.


If the U7 pin 2 and the U4 pin 5 voltages are the same, I would suggest 
a replacement of U4 may be in order - but first check for a solder 
bridge across C87 - that would drag the U4 pins 1 and 2 voltages down to 
close to zero.

have 0.760 @ pin8, 0.000 @ pin 13, and 0.00 @ pin 15.

R30 is now showing 8.04V, but 40M is reading in the 13000khz range, with L30
able to adjust frequency but not voltage. 

I'm thinking I may need to add back in the turn that was removed from T5
earlier to bring everything into spec?

Re: [Elecraft] K3: vs a Collins S-line RX

[stan levandowski]

Bill, I don't have a Collins but...the "poor man's Collins" aka the 
Drake 2B is every bit as sensitive as my K3 to my human ear.  When 
things heat up, though, the K3 pulls away at a rapid rate and wins hands 
down.   Couldn't afford a Collins back in the 60s and *still* can't 
afford one today!!!  73, Stan, WB2LQF

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[JeremyJones]

C62 is correct, and the path is intact.  Reflowed the solder on all
connections just to be sure.  
U4 readings are as follows
Pin1 = 0.111
Pin2 = 0.339
Pin3 = 0.006
Pin4 = 2.363
Pin5 = 4.99
Pin6 = 4.99
Pin7 = 4.99
Pin8 = 4.99
Pin9 = 0.001
Pin10 = 0.001
Pin11 = 0.000
Pin12 = 0.000
Pin13 = 5.029
Pin14 = 5.029
Pin15 = 5.029
Pin16 = 5.029

Pins 1, 2, 7, 8, 12, and 13 are not within the specs in the manual.  Is this
a bad U4, or should I start tracing backwards?

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

That 5 volts at U4 pin 13 is higher than normal, and is the reason you 
do not have any control over the frequency of the VFO.
Make certain the path from the VFO output through C62 to U4 pin 4 is 
intact with good soldering all the way.   Check the value of C62 (0.01 
uF marked 103).  Make certain pins 5, 6 and 7 of U4 are properly 
soldered.  Do the DC voltage checks on U4 and let me know the results.

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

OK, let's back up to U4 and U6 for a bit.  Set the K2 to 7100 kHz and 
tell me the voltages at U4 pin 13. U6 pin 6 and U6 pin 7.

You can remove the bridge between L30 and T5.

Also lift one lead of the red winding on T5 and check the resistance 
across L30.  In the row of 3 pins, resistance between the leftmost pin 
and the rightmost pin.


Technical talk - L30 and the red winding of T5 should result in a lesser 
inductance than either of them alone.  It appears as though you have 
only T5 in the circuit.  An open winding at L30 would make the frequency 
too low - your present condition.
The reason for the request of the DC voltages at U4 and U6 is to 
determine if U6 is operating as expected and there is the expected drops 
between U4 pin 13 and U6 pin 6.

be sure.

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

I did some "playing with numbers" in the VFO resonant circuit, and I am 
coming to the conclusion that L30 and T5 are not connected together.  If 
my speculation is correct, you will find a break in the PC board or 
something not soldered.
With the K2 upside-down, look at the bottom of L30.  There is a row of 3 
pins.  The leftmost pin connects to the adjacent lead of T5.
Solder a wire across those two points as a test.  Then check the 
resistance to ground at the rightmost end of that row of 3 pins - it 
should be zero.


Let me know what you find.

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

Unless you have a typo, the 40 meter VFO frequency is too high while all 
the rest of the bands is too low.

Make certain that the value of C71 is 82 pF and re-flow its soldering.
Set the K2 to 7000 kHz and re-measure the VFO frequency - probe in TP1
Next (while you are still in CAL FCTR, turn the slug on L30 Without 
moving the VFO knob) to see if the frequency moves.  If it does not, 
re-flow the soldering on the pins of L30.  If the frequency does move, 
then T5 and L30 are properly connected, and that is what I wanted you to 
check.
Go to the secondary menu (tap DISPLAY) and check the parameter for D19 - 
it must be "n".


When re-flowing the solder, use a hot (750 degF) iron and add just a 
tiny dab of solder - you actually only need to add a bit of flux.
Watch the solder to be certain it flows out fully onto both the solder 
pad and the lead.  If you can see a distinct edge to the solder on the 
pad, that connection is suspect - it did not receive enough heat or was 
not heated long enough.


If all was as expected for the tests above, inspect the pins of relays 
K13, 14 and 15 carefully - you are looking for any whisker of solder 
that would form a bridge between two pins.


Next, move your search to the left of the VFO on the schematic, and 
check all the components in the U6B circuit for correct values and good 
soldering.  Make certain all components are in the proper holes - 
sometimes there is a via hole next to a solder pad and the component 
lead can be placed in the via hole instead of the solder pad.  When you 
have finished that inspection, power on and check the voltage at U6 pin 
5.  If it is not 4 volts, you have a problem on the small thermistor board.

Don W3FPR

Jeremy,

I have read your exchanges with Gary,

First, don't bother with the C22 setting - just set it to the midpoint (slot 
parallel with the long edge of the board) and leave it there until you have the 
rest of the K2 receiver working on all bands, and then go to my website 
www.w3fpr.com and do the procedures stated in the K2 Dial Calibration article 
there.

Taking things one step at a time - is the PLL Range correct at TP3? Tap BAND+ 
to bring it to the highest frequency (about 12100 kHz) then tap BAND- to get to 
the lower limit (about 12087 kHz)  Those frequencies can vary by 2 to 3 kHz 
from the target values and still be OK.

Once assured that the PLL Range is correct, then tackle the VFO frequencies.
You do have something wrong there because your frequencies are too low on all 
bands.  That indicates either too much capacity or too much inductance is 
present in the VFO circuit.  Look at the schematic for RF Board sheet 1.  The 
area in question is in the upper right corner - the input side of Q18 - as well 
as the VFO range Select components.

Is T5 wound on a yellow core?  If wound on a red core, it will have too much 
inductance.  Does L30 have a slot across the entire diameter of the tuning 
slug?  It should.
Look at the tops of D23, D24, D25 and D26.  They should have a top shape like 
Q18 and about the same size.  D21 and D22 should have a smaller body profile 
when viewed from the top.  The wider flat side of all those varactors should be 
facing toward the rear of the RF Board.

Your next step is to check the relays K13, 14 and 15.  The white stripe should 
be on the end toward the rear of the RF board.

Examine the bottom of the board for the soldering of those components in the 
VFO and VFO Range Select areas to be certain there are no tiny solder bridges.

If everything is correct, it *should* have close the frequencies listed in VCO 
Table on the Schematic Key page - within 3 to 5 kHz when everything is correct.

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[JeremyJones]

Hi Don,

I set C22 to midway. 
PLL @ TP3 is 12099.12 - 12086.32. 
T5 is a yellow core, wound with 15 turns red and 4 green. I had to bring it
down to 15 turns as recommended by Gary to get 8253.86khz @ TP1 when tuned
to 4000.10 for the VCO test.  It was around 7694.39 with 16 turns. 
L30 is the correct part, and all diodes have been checked to ensure the
correct part and placement. 
Soldering has been checked. 
Verified C67, C65, C64, C68, D13, Q18 for value and orientation. 
Relays click when changing bands. 

Still getting the following readings. 
3500 = 8248.42
7000 = 12010.78
10100 = 14157.67
14000 = 16976.67
18068 = 18878.23
21000 = 15211.55
24890 = 16977.38
28000 = 18878.84

I am at a loss for what to look for next. Everything seems to check out, but
my readings are still off. Anyway I can try to isolate a faulty component?

Re: [Elecraft] rf interference on smoke detector

[Ron D'Eau Claire]

FWIW, I have new First Alert Model Model SA300 smoke detectors. They are
powered by 10-year batteries. The end of my 110 foot inverted L antenna
comes right into the shack through the wall to the tuner on a shelf about 15

I have used that antenna at 500 watts on 160 through 10 meters without

Re: [Elecraft] K2 VCO Alignment only 0.02V @ R30

[Don Wilhelm]

Jeremy,

I have read your exchanges with Gary,

First, don't bother with the C22 setting - just set it to the midpoint 
(slot parallel with the long edge of the board) and leave it there until 
you have the rest of the K2 receiver working on all bands, and then go 
to my website www.w3fpr.com and do the procedures stated in the K2 Dial 
Calibration article there.


Taking things one step at a time - is the PLL Range correct at TP3? Tap 
BAND+ to bring it to the highest frequency (about 12100 kHz) then tap 
BAND- to get to the lower limit (about 12087 kHz)  Those frequencies can 
vary by 2 to 3 kHz from the target values and still be OK.


Once assured that the PLL Range is correct, then tackle the VFO frequencies.
You do have something wrong there because your frequencies are too low 
on all bands.  That indicates either too much capacity or too much 
inductance is present in the VFO circuit.  Look at the schematic for RF 
Board sheet 1.  The area in question is in the upper right corner - the 
input side of Q18 - as well as the VFO range Select components.


Is T5 wound on a yellow core?  If wound on a red core, it will have too 
much inductance.  Does L30 have a slot across the entire diameter of the 
tuning slug?  It should.
Look at the tops of D23, D24, D25 and D26.  They should have a top shape 
like Q18 and about the same size.  D21 and D22 should have a smaller 
body profile when viewed from the top.  The wider flat side of all those 
varactors should be facing toward the rear of the RF Board.

>From Jeremy
To Gary
Adjusting the windings on T5 and moving the slug in T30 up has given me
11914khz on 40m. The other bands are still way off. Cal PLL still gives
error 232. I've tried running it at 7000, 7050, and 7100khz. Checked the
diodes and all are correct and in the right spot. 

Oddly enough I was able to get it to run Cal PLL by turning T30 until I got
12003khz at TP1.  Came across this by forgetting the probe in TP3 and
running Cal PLL. Moved the probe to TP1 and adjusted T30 and Cal PLL ran. 

C22 only has an adjustment of less than 1khz (12085-12086) @ TP3. 
R30 which should have 6V only has 0.02V.

The freq. is still too low at TP1. The PLL cannot lock and the VCO will not

for the PLL/VCO to lock onto the expected freq.

Something still seems to be wrong too, with the VCO freq.'s on the upper
bands. Too low of freq. means there is either too much inductance or too 
much capacitance in the T5 circuit. If it is not T5 and some bands are OK or
close to OK, then it is likely that for some reason, there is too much C in
the circuit still. This could be from an incorrect cap, a VCO relay is not
releasing some of the caps, or the varactor diodes are of the wrong type or
are in the wrong places. Check to see if maybe you mixed up the MV209
diodes with the 1SV149 diodes.

Try expanding the red turns on T5 as much as possible, and turn the slug in
L30 so it is near the top of the coil. See if then the VCO freq. will come
close enough to the stated freq.'s for the PLL to lock when you do CAL PLL
which is done only on 40m. If it is not within about 5-10kHz, CAL PLL will
not succeed.

Hi Jeremy,

OK on the civilian call sign. Note that our radios are primarily intended to
cover the US ham bands, and there is limited freq. coverage outside of those
ranges due to the design of the VCO/PLL. The K2 is not general coverage.

You might first try doing a hard reset by holding down the 4,5,6 buttons all
at the same time when the power is turned on. This ensures the IOC sets the
freq. boundaries correctly and all of the defaults are set. Release the
buttons in 2-3 seconds and then wait about 10 seconds for the INFO 201
initialization to complete normally. This is usually done the first time the
rig is turned on, but if it was interrupter or did not complete for some
reason, the rig could be in an indeterminate state.

The VCO frequencies you stated are too high. Try expanding the red turns on
VCO inductor T5, or if necessary - remove a turn.

Use care to not damage the plated through holes if you do need to remove T5
to rewind it.

 Be sure there is no mistake in ID-ing the caps in the VCO circuit too, and
make sure none of the VCO relays have any soldering iron burns to their
case, they are not reversed on the PCB, and the pins are well soldered. See
the VCO Table again for which caps are used on which bands, and verify those
are all correct, and they are well soldered, as well as the VCO relays that
switch them. Check each and every part and soldered connection in the VCO /
PLL area.

Check that U6 pin 1 (LMC662) on the RF Board moves between 0VDC and about
7.5VDC when you do the PLL range test. If not, there is probably a problem
with the little PLL reference oscillator thermistor board, usually a poor
connection. Remove the left si

Re: [Elecraft] annoying problem

[aj4tf]

I recently installed a CO alarm (required by code) and I observed a
sensitivity to 40m transmissions.  It only occurs when I am about around
50W... the alarm goes off for a few seconds.  My antenna (dipole cut for 80m
with a tuner) is on the outside of the house right now, but I have plans to
move it out to the trees someday.  Since the alarm is the plug-in type, it
won't be easy to install an AC rated cap across the line (although I guess I
can put it in the outlet box).   

I have two solutions for this problem at the moment:

1) Only work 40m when the XYL is not home
2) Eventually get the antenna away from the house.

[Elecraft] No autotune on FSK-D

[Stephen Prior]

I have just had a play with RTTY, not something that I do very often.  I'm
using the FSK-D mode with entry from a keyboard in the back of the P3 -
works fine on PSK and CW.  However, I have found that when I tap the SPOT
button on the K3 it does not auto tune as it does in PSK-D for example.  I
do have CWT showing.  What happens is that I get 'SPOT' appear on the K3's
display and it just stays there with no effort to initiate auto tuning.  In
the monitor I hear a continuous tone which  is the same frequency as the
RTTY high tone.  In other words its behaving as I suspect it would if CWT
were not selected.

I've had a dig through the manual but come up with nothing, but as my xyl
would say, I'm useless at finding anything!!

Re: [Elecraft] K3 Atennuator

[John Lemay]

I think Rons suggestion will only work if ...

 

i), you turn off the AGC and 

 

ii), the linear range of the audio stages is not exceeded.

 

Otherwise, the AGC will work to keep the audio level relatively constant -
that's what it's there for !

It's easy to confirm both the preamp and atten effect on the signal using
the excellent built-in tools in the K3. Switch the display to show the audio
voltage, tune in a signal, and switch between 'in' and 'out' with your
preamp or attn noting the voltage level change.

To convert to dB, it's a simple log function found on most inexpensive
calculators:

dB= 20log(V1/V2) where V1 and V2 are the two voltage levels noted.

Of course you can do exactly the same thing to compare the gain (or loss)
when comparing antennas, etc., in the signal path.

Hi Mike,

I did a quick search on the word attenuation and found this older e-mail
from Lyle of the Elecraft crew.

How much attenuation does the Attenuator put in line?

Approximately 10 dB, not adjustable.
