Is it possible to order a KRX3 *without* a synthesizer board? If it were,
there would certainly be a better market for the old boards.

I would be much more likely to upgrade to the new KSYN3 for my two K3's,
each with two receivers, if I could recover some of the cost by selling the
old synthesizers.

Re: [Elecraft] Deleting Macros from the K3

2014-06-13 Thread Stan Gibbs, KR7C
In the "Edit Macros" window of the utility, first read macros 1-8 from the K3
to make sure you keep those that you don't want to erase, clear the text
from the "Macro Commands" textbox for each macro you want to erase, and then
write macros 1-8 to the K3.

The macros should be:
 MN120;MP000; (CW Key 1 tip=dot) bit 1 is CLEARED
and
 MN120;MP002; (CW Key 1 HAND) bit 1 is SET

You should only provide the bit value for the parameter selected by the MN;
command.

The best way to see the correct command is to use the utility to read the
value for whatever parameter you are interested in (in this case MN120)
after you set it to the value you want manually on the KX3.

If you want to understand the inter-radio interference issues you face, the
potential for damage they may cause, techniques to measure their magnitude,
and measures you can take to minimize them, I suggest you get a copy of
"Managing Interstation Interference" by George Cutsogeorge, W2VJN.  It is
available on the web from Inrad.

There is a very useful section toward the back about using the station
radios themselves to measure the interference.

Re: [Elecraft] KAT500 Utility 1.14.4.10 beta test version available on our FTP site

2014-04-11 Thread Stan Gibbs, KR7C
Yes, I was typing the commands on the Command Tester tab.

I notice from my P3's 28.004 oscillator signal that the oscillator is
enabled immediately when the Firmware or Operate tabs are selected. 
However, the oscillator runs continuously while the Operate tab is selected
and turns off after a delay in the case of the Firmware tab.  Is there a
reason for this difference?  Sending firmware to the KAT500 with idle sleep
enabled seems to work reliably now, even waiting for the oscillator to
time-out first.

The Configuration and Command Tester tabs don't enable the oscillator until
the user either clicks a configuration button or sends a macro command.  In
both cases the oscillator stops after a few seconds of idleness, like the
Firmware tab.

Why not simply enable the oscillator (disable the sleep) after the utility
has established communications with the KAT500 on startup, and restore the
user's Idle Sleep setting on exit?  If users are fiddling with their KAT500
configuration, it doesn't seem like they should be that concerned about the
28.004 signal being present.  If they are using the Operate tab to monitor
station operation, then the oscillator signal will be present regardless of
the Idle Sleep setting.

However, this begs the question of other apps accessing the KAT500.  IMHO,
requiring all of them to send junk commands until they get a reasonable
response does not seem like a very reliable strategy.

Is there a hardware mod that could be made that would shift the oscillator
out of the 10m band?  That would eliminate the problem altogether, allow the
firmware to be simplified and greatly improve the communications
reliability.

With the new utility, I am still seeing incorrect responses from commands
when the oscillator sleep is enabled.  The oscillator does start after one
"an;" command, but the correct "AN1;" response does not occur until I send
two more "an;" commands.

I would expect to see the correct response after the first "an;" command, as
happens when the idle sleep is disabled.

Re: [Elecraft] Sub RX and P3

2014-04-04 Thread Stan Gibbs, KR7C
Ed,
You are confusing "markers" and "cursors".  The VFO A receive frequency is
denoted by a green "cursor" and VFO B by a red cursor (when SPLIT is
active).

The markers, MKRA (green) and MKRB (magenta), are used with the Select
button to QSY the K3, but they do not necessarily indicate the active
frequency of their respective VFO except when that button is pressed.  Page
16 of the Rev D manual has the full details.

If you put the rig into SPLIT mode, you can see all 4 indicators at once on
the P3 screen if you want.

Gary,

If you don't want the sub-receiver engaged, then take out the "SB1;" command
in the SPLITSUB macro:

SPLIT:SWT13;SWT13;FT1;UPB4;RT0;XT0

and the "SB0;" command in the NOSPLIT macro:

FT0;RT0;XT0;SWT13;SWT13

Of course, you can use any subset of these commands or add others giving you
a very powerful capability to customize the operation of the K3/P3.  I
understand that the PF1 button is not the one you like to use, but you
should try it; you might like it once you get used to it.

I will say that it would be cool if you could send K3 serial commands from
the P3's function buttons, but, as Joe said, there are many requests on the
list that may get attention first.

Re: [Elecraft] P3 & marker B transmit freq.

2014-03-19 Thread Stan Gibbs, KR7C
Gary,

If you are willing to push a different button than MKRB, you can modify your
DX split procedure by using the PF1 and PF2 buttons to execute a macro that
puts turns the sub-receiver on, copies VFO settings from A to B to make sure
they are on the same band and consistent, sets VFO B to be the transmit VFO
and puts the rig in SPLIT mode. It also moves VFO B up 1 kHz (UPB4;) and
finally makes sure that RIT and XIT are off. When the rig is put into SPLIT
by the "FT1;" macro, the P3's MKRB will appear automatically

If you do this, then holding PF1 instead of MKRB accomplishes everything you
are trying to do.  Holding PF2 restores the simplex DX configuration.

Macros are programmed from the K3 utility's "Command Tester/K3 Macros" tab.
I named my macros "SPLITSUB" and "NOSPLIT", which are displayed in the VFO B
area when the macro is executed.  The text below before the ":" is the macro
label, and the text after the ":" is the macro command string. Follow the
process on page 6 of the K3/KX3 Programmer's manual to create the macro,
download it to the K3 and associate the PF1/PF2 buttons.

SPLITSUB: SB1;SWT13;SWT13;FT1;UPB4;RT0;XT0

NOSPLIT: SB0;FT0;RT0;XT0;SWT13;SWT13

Apparently, the KAT500 Utility (v1.14.2.20) doesn't send the requisite "wake

As far as the coarse tuning speed, I would say that it is much faster than
1.58.  I erased all memories and tried tuning antennas where the SWR is over
5 (e.g. 18 on my 80 dipole) and the KAT500 was really quick in finding a
good match.

Re: [Elecraft] Need volunteers to try an even better version of KAT500 firmware (rev. 1.63) -- more accurate initial tunes

2014-02-25 Thread Stan Gibbs, KR7C
In trying to load this new FW version, I discovered that there appears to be
an interaction between the proper operation of the serial interface and the
"Sleep When Idle" option.  If the oscillator is not running due to the
timeout enabled by this option, as can be seen on my P3 at 28.004 MHz, then
a serial command does not work reliably and firmware updates produce an
error message about an incorrect device.

>From a quick and dirty experiment, it looks like the first typed "an;"
command restarts the oscillator but produces no output.  The second command
also produces no output.  The third "an;" produces the expected "AN1;"
response.

After disabling the "Sleep When Idle" option, the firmware load was
successful.

Has anyone else seen this?

Thanks, David. I never loaded 4.57 and the current notes on the Elecraft K3
firmware page don't include this item.  I'll have to be more careful to read
all of the release notes for versions between that last loaded and a new
one.

This would have been a more seamless upgrade if the firmware had been able
to detect the K3EXREF module and "do the right thing"; that is, if the
module is present, set the config menu item to enable it.  Hard to imagine
why I would install the module and then not use it.  Perhaps the detection
is not possible.

[Elecraft] FW 4.67 and K3EXREF

2013-07-06 Thread Stan Gibbs
I just realized that both my K3's running FW 4.67 are no longer locking to
the K3EXREF calibration signal from a Trimble Thunderbolt. Specifically, the
"REF CAL" config menu item does not show the flashing asterisk and moving
the main tuning knob does not show "LOCKED". I have had the K3EXREF
installed and operating properly with both rigs for at least a year.  

The Trimble Thunderbolt provides the 10MHz calibration signal to both K3's
though a MiniCircuits splitter. After checking the power supply and output
levels of the Thunderbolt, which were nominal, I decided to see if the K3
firmware could be responsible, since I had fairly recently upgraded to 4.67. 
Indeed, rolling back to 4.51 re-enables the normal "REF CAL" behavior!

Can anyone else verify this?

Re: [Elecraft] K3 Front End Protection

2012-12-13 Thread Stan Gibbs
Fred,

The best source of good information that I have found on operating multiple
radios safely is the book by George Cutsogeorge, W2VJN: "Managing
Interstation Interferrence".  It covers all the issues with running SO2R as
well as other multi-transmitter configurations, and provides techniques to
measure interference and mediate it.

The book is available from Array Solutions here:
http://www.arraysolutions.com/Products/Books/W2VJN_Interference.htm

Antenna isolation is the name of the game and, particularly with QRO,
requires a great deal of care and planning.  I run 100W in an SO2R
configuration with 2 K3's on a small city lot.  My solution to the isolation
problem has been the use of W3NQN bandpass filters and antenna geometries to
minimize interaction.  Using W2VJN's analysis techniques and employing some
of the possible solutions noted by him, I can operate safely and have
confidence that I am not damaging my K3's receiver.

Good advice. Since I will be installing the KRX3 and KPA3 after basic

Re: [Elecraft] rf gain

Terry,

Here is a link to a 2010 thread about this issue: 
http://elecraft.365791.n2.nabble.com/K3-Rf-gain-tracking-main-vs-sub-td5668917.html

The thread doesn't document the resolution (for me, EEINIT), unfortunately,
but there is an interesting graph of the behavior by one of the contributors
(HB9BRI) who also experienced the issue.

Perhaps there is some information in the thread that will be of help.

Did you verify that the behavior is still present after an EEINIT but BEFORE
you reloaded your configuration? (I'm assuming that you did an EEINIT, of
course).

Re: [Elecraft] rf gain

Yes, Don, an EE INIT is not something one should do "arbitrarily".  It did
fix a similar non-linear RF gain problem of that myself and others reported
on this reflector back in 2010, so I suggested it as a solution.

The process in the owners manual makes clear that a saved configuration is a
very important step if one does not want to undertake a lot of parameter
setting and calibration.

As to running the RF gain calibration, this did not solve the non-linearity
for me, but the EE INIT did.

John,

I had a similar experience to you (though without the 30/80 module).  My P3
showed strong 60Hz modulation of the output signal on 20m and a much smaller
modulation on 40m (not audible).  The audio on 20m was definitely "raspy".

The KX1 was connected to a dummy load via 25 ft. of RadioShack RG58 and I
had no antenna on the K3.  I thought the modulation was an oscillation at
first, but after monitoring the KX1 output signal on my scope, I realized
that the modulation had to be due to some other cause, and I suspected RFI
in the power supply or cables because of the 60Hz sideband spacing.

I changed my coax to a 3 ft piece of RG213.  The 20m signal immediately
became clean on my K3.  The longer the coax, the more apparent modulation of
the received signal.

All signal reports that I received from QSOs gave me a clean tone report and
I asked several ops whether there was any hum or buzz on my 20m signal. 
Nobody reported any modulation.

Do you have a scope to look at the KX1 output?  If not, you might want to
get some on-air reports to determine if there is a real problem in the
transmitted signal.

Re: [Elecraft] kx1 20 meter oscillation

Rick,

Thanks for your words of caution. I understand the issues and have tried to
be very careful not to overload my K3.  The KX1 signals on my P3 have been
in the S9 region.  Typically, I was driving a dummy load with my KX1 while
my K3 was sampling my dipoles outside, about 30 feet above my shack
location.  I don't plan to chase this goose any more at this time, but I
will try to run an experiment by taking my KX1 way out of the near field of
my antennas and see if there is any change to the spectrum on the K3/P3.

Don,

I took a look at all those components, their values and installation, and
everything looks normal.  It may be that one of those components is bad, or
that the DDS is exceeding its spec harmonic output for some reason.

I'm not certain that these harmonics are not somehow an artifact of my using
the K3/P3 as a spectrum analyzer.  And, I'm also not certain how to
determine the answer, short of picking up a spectrum analyzer.

Thanks for your support and time on this.

Thanks for taking the time to check out your rig for comparison.  Good idea
to email Elecraft support.  Gary's numbers were very similar to ours, so I
guess the negative voltage is, as you say, a red herring (is there any other
color?).

If you get a chance to scope Q7's terminals, I would be very interested in
the results.

I finished the ATU this morning and everything seems to be working well,
though the low 40m power still knaws at me.  I think I'll put the sideband
issue on the back burner as long as nobody reports a crappy signal.

And, I'll definitely get up a hill soon!  After all, the KX1 is really a
sweet little rig designed just for such a purpose.  Kudos to Elecraft once

Re: [Elecraft] New KX1 low power and 20m oscillation

2012-05-08 Thread Stan Gibbs
Don, I tried your experiment but it had no effect. I just grounded point A
because it is damn hard to jumper Q7.  R28 measures good and is well
soldered.  It has -0.25V or so on the base side and 5.5V on the other during
transmit.

I also tried reducing the drive pot and, while the signal definitely
declined in amplitude, the sidebands were still present.

Could this just be an artifact of using my K3/P3 to view the waveform?  If
so, why would the 40m signal be so different?

As I said in my original post, Q7 is the place where my DC troubleshooting
measurements differed from specs.  The base of Q7, which is supposed to be
0.7V, is -0.895V on 40 and -0.195 on 20.  The voltage on Q7 should
definitely be positive in order for it to ground capacitor CA, so something
is screwy.
  
Someone suggested that either C45 or C32 were possibly bad, allowing RF on
to the base of Q7, which might cause the bogus voltages.  I tried adding
additional capacitance in parallel with C45/C32, but that had no effect.

Which core are we talking about?  The manual says to "squeeze" the windings
of L2 if the 40m power is lower than 20m. I tried that and it did seem to
raise the 40m power, though still not as high as 20. 

I think some of the extra power on 20m is due to the spurious sidebands that
I observe. I really would like to understand what is causing that phenomenon
because it tells me something just isn't right and because I don't feel
comfortable operating with such a signal, despite the fact that other
stations give me good reports.

Re: [Elecraft] New KX1 low power and 20m oscillation

2012-05-07 Thread Stan Gibbs
The 20m waveform on my P3 seems very broad, but I don't think that it is due
to any kind of oscillation.  The signal is 20 KHz wide at about 40 dB down. 
I don't know if this is normal or not, but I did manage to make 20m and 40m
QSOs last evening with good signal reports for both.

I made the power mod and the 40m power is now 2.8W and 20m power is 3.2W. 
Probably adequate for my SOTA needs.

Re: [Elecraft] wiring the KX1 paddle

2012-05-07 Thread Stan Gibbs
I just finished building the KXPD1 paddle for my KX1.  After examining the
situation, I really felt that having to solder the wires to the plug after
the paddles were on the body would be unnecessarily difficult.

I decided that it would be much easier to attach the wires to the plug first
and work on the proper routing of the wires to the paddle circuit boards
with the stereo plug inserted in the body of the paddle.  I did a lot of
position testing of the paddle circuit boards and wire bending, but the
results were very nice, and I had plenty of room to work.

I think it was a very straightforward way to assemble the KXPD1.

Re: [Elecraft] New KX1 low power and 20m oscillation

2012-05-06 Thread Stan Gibbs
I may have been a bit hasty in concluding that there were oscillations on
20m; after I disconnected my K3's 20m antenna, the 20m signal looks fine. 
So I may have just been overloading the K3's front end.  Not sure why the
40m signal didn't suffer the same issue, though.

Still have a very low power output (1.7W 40m, 2.0W 20m) and I've done all
the suggested troubleshooting in the manual.  Components all look in their
proper places and well soldered.

[Elecraft] New KX1 low power and 20m oscillation

2012-05-05 Thread Stan Gibbs
Just finished building the KX1 and the transmit testing is not going well. My
only bench tool is a DVM.


Power supply is a 13V battery.  Ant is a 50 ohm dummy load. The receiver
seems to work fine.  All DC voltages on RX are nominal.

On 40m TX, I get about 1.5W out.  The signal is clean listening with my K3. 
On 20m TX, I get about 2W out but there is a horrendous audio oscillation. 
My P3 shows huge sidebands on the signal.

All the TX DC voltages look good EXCEPT for the base of Q7, which is
supposed to be 0.7V.  I measure
 -0.895V on 40 and -0.195 on 20.  I have examined all the suggested areas,
but I don't find any obvious problems.

Anybody have a suggestion of a cause of this behavior?

Barry,

According to the help file, the contest duration has to be changed manually
in the .ini file.  If I do that, I see the expected behavior for the WPX and
HST competition modes.

Unfortunately, MR doesn't reset the duration to the Duration value if you
change back to either the Pile Up or Single Calls mode.  In that case, the
Duration .ini item gets overwritten by the competition value on exit, unless
you are careful to change it after leaving competition mode.

Re: [Elecraft] [K3] Changing COM ports crashes latest K3 utility

2011-09-09 Thread Stan Gibbs
I'm running Win7/64.

Dick D. has provided me with a new version of the K3 utility for testing
that does NOT fault on my machine when I change the COM port FROM an invalid
or unconnected port.  This situation can arise after changing the machine
configuration or the port that one is using to talk to the K3.  The default
COM port, which may no longer be valid, is picked up from the registry.

Nothing specific was identified as being causative, but the exception is no
longer thrown under those conditions.

Thank to Dick for the help.

Re: [Elecraft] K144XV output power range

2011-08-09 Thread Stan Gibbs
Thanks to those who responded.  It is evident that my K144XV is not
responding as expected to the K3's front-panel power control byreducing
output down to approximately 1.0 W at a drive level of 0.1 mW.

While it would be easy to blame my power meter, I have also noted this
behavior with an attached power amplifier.  The minimum output power floor
was no where near what I would have expected from a 1 W drive if the K144XV
had been providing that.

I have my CONFIG: XV1 PWR value set to L 1.0.  I do have a K144REFLK option
installed.

Anyone have an idea as to what might cause this behavior?  I really need to
be able to provide a reliable 5 W output from my K144XV.

If the routing of the TMP cables to the K144REFLK board is critical, how
should they be routed?  The assembly manual is mum on this question.

[Elecraft] K144XV output power range

2011-08-08 Thread Stan Gibbs
My external watt meter does not agree with the power output bar graph display
on the K3 except in the very middle of the power range.  While turning the
power control from 0.1 to 1.0 W., the bar graph shows the expected 1 to 10
display.  But my watt meter display goes from about 5.8 to 7.5 W.

Does my watt meter really suck, or is this a behavior that others have seen? 
The K144XV manual suggests that an upper value of 7.5 W is not unreasonable
given the accuracy of most meters.  But 5.8 W for a minimum output power
seems way too high.

Anybody have numbers to compare?

Re: [Elecraft] [P3] P3 and K144XV

2011-08-06 Thread Stan Gibbs
Tom,

Sounds like your "Ref Lvl" is set too high.  The color of the waterfall
reflects the vertical position of the trace in the frequency display.  If
you reduce the reference level, the frequency display will return to a
viewable position, and the orange waterfall will revert to blue.

The reference level is per-band so you have to adjust it for each band you
operate on.  For my 2m setup the ref level is set at -145 dBm, which allows
me to see the frequency trace when the pre-amp is on or off.

Hi Don,

Thanks for the response.

If I read the KRC2 and XV144 manuals correctly, the way this would be set up
is to use the DB15/DB9 cable provided with the XV144 to connect the K3 to
the KRC2 "XCVR" DB9 connector and then use a DB9/DB9 straight-through cable
to connect the XV144 to the KRC2 "PC" port.  Is that correct?

It seems a bit strange that the KRC2 kit doesn't provide a DB15 connector as
well as a DB9 for making up the control cable.

Re: [Elecraft] ATU Question

2011-05-24 Thread Stan Gibbs
Bill,

>From page 22 of the the K3 owners manual: "Up to 30 ATU settings are saved
for both antennas on every band."  When you hit ATU TUNE, the K3 stores the
tune settings for the KAT3 at the current frequency and for the current
antenna.

In AUTO mode, if the K3 determines, on transmit, that the current KAT3
tuning parameters should be replaced, it will automatically load them when
you key the transmitter.  You can tell this is happening because the ATU
icon will flash briefly on transmit.

As to how the K3 determines whether to load new parameters, I would surmise
that the K3 checks the ATU "map" each time you transmit, checking whether
the current set of KAT3 parameters best match the current transmit
frequency.  If it finds a better match, it loads them.

For example, if you have previously hit tune at both 14.020 and 14.170, have
been operating at 14.150, and now try to transmit on 14.050, the K3 will
automatically load the parameters stored for 14.020.  This is conjecture on
my part, since I have not seen any documentation of the firmware algorithm. 
But it seems reasonable and in line with what the K3 actually does.

Thanks for the response, you were 100% on target!  I was a bit lazy, I
guess, when I set up the preset for WSJT, and didn't clear the "Sound card

be used in preference to COM port PTT, but, with WSJT it is clearly a
problem.

[Elecraft] K3 always in TX with WSJT

2011-05-12 Thread Stan Gibbs
I'm just beginning to work with WSJT/JT65B and I'm running into behavior
(versions 7 and 9beta) that I don't understand: as soon as I startup WSJT,
the rig goes into TX mode and stays there; I have to kill WSTJ to get the K3
out of TX mode.

The K3's config PTT-KEY option is RTS-OFF.  I'm running through a DigiKeyer
II and have successfully run WSPR, as well as other digital modes, with the
same hardware and software configuration.  I believe I have the MicroHam
router setup correctly with a single COM port for 2nd PTT.

Anybody have an idea why the rig is keying by default?  Am I just
misunderstanding what I should see when WSJT starts up?

Thanks for the confirmation, Alan.  I was aware that the behavior was only
present in fixed-tune mode, but forgot to mention that fact in my posting.  

The fix will greatly improve SO2V operating with the P3.

[Elecraft] P3 Strange Display Behavior on BSET

2011-05-09 Thread Stan Gibbs
I'm running P3 firmware 1.05.

If I have my SubRX enabled and the two receivers tuned to two different
signals, my P3 cursors are displayed exactly as expected.  If I then hit
BSET, the P3's VFO A cursor and display (including the displayed VFO
frequency) shift to the VFO B frequency, despite the fact that the audio for
both RXs does not change, indicating no change in the VFO A in reality. 
This also results in an incorrect display for the VFO B cursor because it is
displayed as though it were tuned to the VFO A frequency.  Tuning the VFO B
is no longer synchronized to the P3 display.

Turning off BSET returns the P3 display to the correct state.

Has anyone else seen this?

If you enable the SPLIT function, VFO B will control your TX frequency and
the P3 has a purple cursor that shows where VFO B is in the band.  I use

Re: [Elecraft] P3 New LVL Cal Function (Beta 0.41)

2010-11-11 Thread Stan Gibbs

I did an EEINIT on the advice of Gary at Elecraft and now my transfer gain is
-12.3 dB.  Don't know exactly what to make of that, or why the EEINIT should
have made a difference, but at least my result isn't so extreme compared to
others noted in this thread.

What is really interesting to me, however, is that after doing the EEINIT, I
did a fresh RF Gain calibration using my XG2 and found that the
non-linearity in the RF Gain calibration that I reported recently is gone!

Thanks, Gary!

Thanks, Bill, for the response.

My K3 is #4181, so the mod is not necessary.  Yes, -18 dB does sound
excessive.  However, I really can't be sure whether the issue is an XG2 that
doesn't output 50uV, or excessive loss in the RX input stages.  I don't have
the test equipment to determine which is correct, unfortunately.

Re: [Elecraft] P3 New LVL Cal Function (Beta 0.41)

2010-11-11 Thread Stan Gibbs

The calibration procedure is very easy to do, and went as described.  My XG2
signal is right on the money at -73 dbm now.

I'm curious what the nominal range of transfer gain is that we might expect
to see.  Mine is around -18 db.  What does this number mean, anyway?

The release notes for this firmware says: "Added many new RS-232 commands". 
Are these documented anywhere; in a P3 Programmer's Reference perhaps?

Re: [Elecraft] K3 - ATU Tune

The power level used by the ATU Tune process is internally set to 5/10W. As
for the K3 power display, during the tuning process, the scale changes from
a max of 100W to a max of 10W. I can't say why your external meter appears
to indicate 100W, but is it possible that your meter is auto-ranging and you
are misinterpreting it?

Yes, I've repeated the calibration with my XG2 on 40 and 20 several times. 
Just to be sure there wasn't something up with the "do the defaults first",
I followed your suggestion and repeated the calibration on 20m, first with
factory defaults, then with my XG2. I'm using the 1.3.10.15 K3 Utility

Nice to know that I'm not the only one seeing this!  Thanks, Paul.

Here's some more data.  Perhaps someone can illuminate us on what it
indicates.

With my XG2 on 20m, and adjusting the main RF gain knob from full CW to full
CCW, the AFV display goes from 2329 to about 18 at the 10 o'clock position,
jumps to 1233, then declines to about 80.  The dbV display starts at +29.3
and declines to -12.4, jumps to +23.6, and then declines to -0.1 at full
CCW.

Remember that the "SCN ADC" results show us that the gain control is linear
in its output.

What could cause the IF gain to behave this way?  Anybody?

Re: [Elecraft] K3 Rf gain tracking (main vs. sub)

2010-10-25 Thread Stan Gibbs

In the process of investigating this further, I tripped over a very nice
diagnostic tool: the Config menu's "SW TEST" entry. This option can be set
to "SCN ADC" to allow monitoring of the 4 potentiometer inputs to the PIC
processor ADCs. This allows one to verify the range and linearity of the
pots very easily.

As expected, the ADC outputs produce a linear count ranging from 002 to 240
for the full travel of the pots (all 4 of them exhibit the same results). 
Those counts correspond to input voltages (from the pots) of 0.039V and
4.71V, respectively, which are essentially what I measured with my
voltmeter.

This method is MUCH easier, however, and eliminates any question as to what
the ADC is actually seeing on its inputs.

Hi Knut,

Actually, the main RX is the one giving me trouble, not the Sub; that was
Mike's issue.  I was trying to duplicate his when I discovered mine. :-) 
The behavior of my main Rx is the same whether the Sub is enabled or not.

I redid the RF gain calibration with my XG2 twice on 40 M and once on 20 M
with no change in the behavior.  I would have to think that some circuit is
not properly aligned or calibrated, but I'm not enough of a receiver expert
enough to know which are the likely candidates.

Thanks,

Sherlock was right; it wasn't the pot.  The behavior of the voltage on its
wiper is exactly what you would expect: a smooth transition from 0V to 4.7V
for the full travel of the knob from CCW to CW.

So, the question remains, what could cause the very non-linear behavior that
I observe with the audio and S meter?

This result also renews my curiosity about whether others have observed any
non-linearity around the 10 o'clock position of the RF gain when listening

Thanks, Mike, I'll do the same measurement and see what it tells me. 
Erratic behavior seems most likely due to a bad pot, but, as Sherlock would
say, theorizing without data is a capital mistake.

Re: [Elecraft] K3 Sub RF gain

With my XG2 as a 40m source, I observe a similar phenomenon with my K3 (SN
4181) Main/Sub RF gains, though the details are quite different.  I'm
running without PRE or ATT and the behavior is the same whether the BW is
2.8 kHz or 100 Hz.

At max gain, both the Sub and the Main generate the same audio level in my
two ears (precision instruments). And, as the gains are reduced, the audio
falls off similarly such that they are both just about inaudible at the
11:00 position on their respective gain knobs.  But the behavior on reducing
the gain further is very different.

The Sub remains inaudible all the way to full CCW.  However, by about 10:00
on the Main gain, the response goes through a non-linearity where the audio
jumps up to a level similar to about 3:00 on the gain dial.  Further
reduction of the main gain reduces the audio again, but never to
inaudibility.

Interestingly, the S meter also displays this non-linear response, climbing
from S7 to S9+30, as the main gain is reduced from the max, until at the
10:00 position it suddenly falls to about S8.  Further reduction of the gain
does not affect the S meter level.

I've repeated the RF Gain Calibration several times with both the 40m and
20m XG2 signals.  I have seen no change in the behavior as a result.

Does anyone else see this kind of behavior?

I think the feature is pretty much already there: When you want to monitor
your TX signal, just go into the Config menu and set the RS232 baud rate to
something other than 38400 (which the P3 expects).  Transmit, and voila!,
your signal is visible.  To turn the default behavior back on, just restore
the baud rate to 38400 and exit the Config menu. You could even assign a
menu command to a PF key to accomplish this.

Seems to work here.  Is there any problem with doing this?

If you follow the tracking number link in the shipping notice email from
Elecraft to the UPS website, you may find that UPS, like FedEx, provides a
link for the recipient to override the signature-at-the-door requirement on
delivery.

The drivers for the Prolific chip set are there to support users of the
previous KUSB version that used them.  

The current KUSB adapter is based on the FTDI chip set (I own one).  The
drivers are included and don't need to be provided on the Elecraft site.

One of the Menu items is labeled "FN Erase".  With that function selected,
tap (or hold) the FN key you want to clear.

Yes, but what's a bit confusing is that the link to the USB drivers on the
K3 software page still tries to download a Prolific driver install package.

The drivers that came with my KUSB (FTDI) seem to work just fine on Vista.

Elecraft has switched to an FTDI-based version of the adapter. I ordered one
recently after confirming that fact with Support. It works like a charm on
Vista and, given the experience of others, would likely solve your issues on
Win7. The new adapter replaced a Prolific-based adapter from Elecraft that
was, basically, unusable with anything but the K3 Utility.

The web site hasn't been updated to reflect the change to FTDI yet.
