 The main advantage of P3 is that it is standalone. No hassles of software
 installation, instantaneous turn on, and excellent integration with K3. 
 But since the  P3's the firmware is proprietary, it is modified dependent
 on Elecraft's priorities.
 
 For instance, a feature I am missing the most in P3 is noise blanker.
 Under heavy power noise, K3's noise blanker can work pretty well but P3's
 screen is covered by noise. In contrast, the noise blanker on SDR-IQ was
 extraordinary, allowing to see weak signals in the present of heavy noise. 
 At least two solutions here: 1) request a feature from Elecraft, or 2)
 call the power company. 
 
 I had many of software crashes with SDR-IQ. Perhaps no longer with new
 computer and new drivers but I have lost enough time...
 
 To tell the truth, the support of LP-PAN is more helpful than the support
 of SDR-IQ.

[Elecraft] Diversity receive w/o dedicated receive antenna

2012-07-03 Thread Erik Basilier

I totally agree with Jim. Diversity receive is the only way I use the second
rx, and I never invested one cent in extra antennas for the second receiver.
For use with my horizontally polarized main antenna I just connect the
second rx to my existing vertical, which works fine even on bands that it is
not designed for. At Field Day I put up a BuddiPole vertical with no coil
and no attempt whatsoever to tune to any band, with a single wire
counterpoise of random length. If I didn't have the vertical at home, or the
BuddiPole for the field, I would just use two pieces of wire and suspend
whichever way is convenient. However, assuming the antennas are not far from
each other, it is important that they have opposite polarizations. 

 

To have the second receiver and not use it for diversity is a tragedy. After
you set the rf gain on the subreceiver to get a decent balance between the
two receivers, you will find that the second receiver often allows you to
hear a station in the second rx that is temporarily unreadable in the main
receiver due to qsb. Also, in crowded band conditions the different stations
within the receiver passband will arrive with varying polarizations, and you
can hear them spatially separated like orchestra instruments on a stereo
sound stage. This is helpful both for ssb and cw. Sometimes it can even
help with multiple cw signals on the exact same frequency.

 

73,

Erik K7TV

 

Your second antenna  does NOT need to be resonant to receive, either by
itself or with another in diversity mode. My receive antenna is seasonal so
I have employed antennas for other bands for receive when it is not up.
While a non resonant will not present as strong a signal, it also will not
present as strong a noise. The S/N ratio is unchanged but the human ear
seems to hear better when the noise is reduced. I typically use an antenna
for the next band (even harmonic).

 

73,

Jim W5QM

Re: [Elecraft] K3 - P3 or LP-PAN comparison

We used to compare LP-PAN / NaP3 to the P3, but the apt comparison now is
with P3SVGA unless the user plans to use a 4 monitor on his PC ;-) NaP3 is
not a resource hog. I am running it on PCs ranging from a P4 to an Atom to
an i3. It runs fine on all of them. The E-MU 0204 can be a hog on older PCs,
but you really have to try to find a PC that slow today.

 LP-Pan/NaP3 is very computer intensive (PowerSDR is a resource hog)

Re: [Elecraft] K3 - P3 or LP-PAN comparison

LP-Bridge is not intended to support every command that every app might use,
but it supports 99% of the commands that most people use, and uses very few
resources. The biggest issues come with macros and commands that require
critical response timing, but LP-Bridge's ability to limit traffic to the
rig compared to splitters that just send everything from all the apps to the
rig is a big advantage.  There are some rules that have to be obeyed when
using multiple apps so that they don't work against each other and confuse
the rig. LP-Bridge enforces those rules at the expense of supporting 100% of
the commands from a given app. In some cases, LPB2 can be more useful if one
app needs complete control and the others can live with the dozen most used
commands.

One source of many problems is the use of USB to serial adapters. You have
to be careful to use a good brand with the proper drivers, especially with
win7 64-bit.

Joe Subich, W4TV-4 wrote
 
 NaP3 is not the only software required with LP-Pan.  Most installations

 both NaP3 and a logging program to share control of the K3.
 
 Several logging packages fail to work properly with LP-Bridge to the
 point that their developers refuse to accept bug reports if LPB is
 running.  The resource load of LP-Pan must include both NaP3 and LPB
 as well as the interference they cause to logging software.  There is
 no such problem with the P3.

[Elecraft] Amplifier keying line delay setting

2012-07-03 Thread Howard Sherer

It appears that the amplifier keying line is always set to operate as 
QSK with
no delay. This keying signal dose not follow the delay that is set for 
the VOX
on CW. The only way that I have found to keep the keying line closed is 
to put
the KX3 into xmit with the front panel button.

Will an adjustable delay for the amplifier keying signal be added in the 
future?

In cw mode:
Make sure QSK is not on.
Make sure VOX is on.
Push in and hold the speed control till CW n.nn appears.
Rotate the speed control to set the drop out time you want.
Anything up to 2 seconds can be set.

Let us know if this doesn't work for you.

Re: [Elecraft] K3 - P3 or LP-PAN comparison

2012-07-03 Thread Dick Green WC1M

Some comments that may be helpful for both threads about the P3:

I have two K3s in an SO2R contest configuration. The K3 I use mostly for
running has an LP-Pan and NaP3. I just installed the pre-amp option in my
LP-PAN, and it works well, but I haven't done a contest with it yet. The run
K3 also has a SubRX that I use almost exclusively for Diversity reception.
The radio I use mostly for SP has a P3 (no SVGA card) and no SubRX.

Both panadapter solutions work well, but I have a preference for the P3,
especially for SP. The main reason is that the P3 display seems sharper and
more responsive to me. This will sound odd, but the signals on LP-PAN/NaP3
seem slightly fat and slow, and the screen display seems more chaotic
that it does on the P3. It could be that the display is just that much
bigger, but I don't know. I've not been able to make the NaP3 display look
as good or respond as well as the P3 display.

The main reason I use LP-PAN/NaP3 on the run radio is to check the band
activity (i.e., is the band open enough to run?) I've tried to use it to
find an empty space to run, but haven't had a lot of success with that. For
some reason, that's easier to do with the P3. 

Another issue is screen real-estate. I happen to have a 24 main monitor
that I use for the contest logger, a 20 second monitor that I use for NaP3
and a bunch of other utility programs and a 7 touch screen I use for a
program I wrote called AntennaMaster that I use to select antennas, tune
SteppIRs, tune my Acom amp, etc. If you have just one monitor, it's hard to
find enough room on it for NaP3 and all the other things you might want to
see during a contest.

As for CPU usage, when I had a core2-Duo system, LP-PAN/PowerSDR-IF used a
lot of CPU and the system fans would be humping it all contest. I worried
about the heat stress that was putting on the system, especially the CPU.
Now I have an i7-based system with an NVIDIA 570 graphics card and the CPU
usage is much lower. CPU usage with LP-PAN/NaP3 is so low I barely notice
that the fans are running a little faster. FWIW, I use LP-Bridge with
Writelog and NaP3, and it works flawlessly.

All in all, if the P3 was a little less expensive, I would use one on the
run radio instead of LP-PAN/NaP3 (anybody want to sell me a used P3?) 

Now, I hasten to add that there are some advantages to the LP-PAN/NaP3 or
LP-PAN/PowerSDR-IF solutions. For one thing, it can provide a sub receiver
if you don't have one. Second, it can produce excellent filtering and audio
for AM B/C stations without having to buy a 6 KHz filter for the K3. For
another thing, PowerSDR-IF has some monitor modes that transform it into a
very useful receive monitor scope (like being able to see the other
station's transmit envelope.) LP-PAN is also a lot cheaper than a P3. Even
if I had a P3 for the run K3, I wouldn't sell my LP-PAN. I would hook them
up together (more feasible with the $25 LP-PAN pre-amp option installed
because the pre-amp helps to compensate for the 3dB IF splitter loss in the
P3.)

On the SubRX, whether money should be spent on that over a P3 depends very
much on what you do with the radio. I would probably go for the sub because
it makes the K3 a much more powerful radio. If you're a DX-er, it's
indispensable because it allows dual-watch. If you're a contester with the
right kind of antennas (ideally, opposite polarity), Diversity reception can
be an unbelievable upgrade to your station -- it was for mine. That said, I
use a full-size 2-el 40m beam at 110' and a full-size 40m 4-square with 60
radials per element. That combo had better be good! As has been noted,
Diversity does require purchasing identical filters for all bandwidths with
which you want to do Diversity reception. If you aren't a DX-er or a serious
contester, then a sub might be less important and a P3 might make more sense
for the dollars you have to spend.

Hope this is helpful.

73, Dick WC1M

2012-07-03 Thread Edward R. Cole

I purchased the sub-Rx for entirely different application: 
dual-polarity diversity eme reception using adaptive SDR sw (Linrad):
http://www.kl7uw.com/LINRAD.htm
I originally bought two filters for the sub-Rx: 2.8 and 13-KHz 
thinking the 13-KHz filter would permit me to run wideband audio to a 
soundcard for JT-65 or Spectran waterfall displays.  But then I 
learned the K3 audio output is filtered to about 4-KHz voiding this 
approach.  Thus, I sold my second 13-KHz filter.

I currently have just one 2.8-KHz filter in the sub-Rx which is 
adequate since DSP filtering can reduce this as needed.  I should 
state I do not do HF contesting or DX chasing so need for a good CW 
filter in the sub-Rx is not required.  I have 13-KHz, 2.8-KHz, and 
400-Hz filters in the main-Rx.

I do have two LP-Pan for connection to both main-RX and sub-Rx IF 
outputs in order to provide audio IQ signals to my computer via a 
four port M-Audio Delta44 soundcard.  This is how I implement my 
dual-pol reception system for 2m-eme and accomplish 96-KHz bandspan 
bandwidth (limit of Delta44 soundcard).

For simple bandspan reception I use the LP-Pan and emu-0202 at up to 
192-KHz bandwidth on the main-Rx.

[Elecraft] Elecraft CW Net Report for July 1st 2nd, 2012

2012-07-03 Thread kevinr

Good Morning,
It is too cold in here to type well.  With night time temperatures 
in the mid 40s the house gets quite chilly each morning.  Right now it 
has warmed up to 50 degrees.  I cannot wait for summer to get here with 
a few days in the 70s or even in the 80s (it could happen).  But the 
forecast is for more cold and more rain.  It is very hard to believe 
there is a record heat wave going on in the US when it is so cold and 
wet here.
Propagation has been bouncing up and down lately.  Sunday's nets 
were tough.  On twenty meters I got one check in from either coast with 
no one in between.  I read there were some storms out east but I could 
not hear them.  Here our storms are milder due to the much lower 
temperatures.  I keep looking forward to the 60 degree days coming up.  
Hopefully the house will warm up enough I won't have to keep the fire 
going to stay warm.

On to the lists =

   On 14050 kHz at 2200z:
K0DTJ - Brian - CA - K3 - 4113
K1THP - Dave - CT - K3 - 686

If any of you want to cool off and feel rain on your faces come to 
the Pacific Northwest.  Our summer is in abeyance for at least another 
month.  But once the clouds clear I am sure the temperatures will 
quickly rise into the 70s (cross fingers here).  This year I am heating 
my greenhouse and the plants are enjoying warm roots.  They are doing 
well and feeding me too.  Plus working in the greenhouse gets me warmed up.

Re: [Elecraft] K3 - P3 or LP-PAN comparison

If you haven't tried it, play with the FFT samples and averaging a bit more.
Also the DSP windowing functions. It should be possible to set the RBW for
NaP3 to be the same, higher or lower than P3, and the setting is saved per
mode and per band. The FFT settings have changed over time with the various
releases of NaP3, so the version you use will matter.

 Now, I hasten to add that there are some advantages to the LP-PAN/NaP3 or
 LP-PAN/PowerSDR-IF solutions. For one thing, it can provide a sub receiver
 if you don't have one. Second, it can produce excellent filtering and
 audio
 for AM B/C stations without having to buy a 6 KHz filter for the K3. For
 another thing, PowerSDR-IF has some monitor modes that transform it into a
 very useful receive monitor scope (like being able to see the other
 station's transmit envelope.) LP-PAN is also a lot cheaper than a P3. Even
 if I had a P3 for the run K3, I wouldn't sell my LP-PAN. I would hook them
 up together (more feasible with the $25 LP-PAN pre-amp option installed
 because the pre-amp helps to compensate for the 3dB IF splitter loss in
 the
 P3.)
 
 On the SubRX, whether money should be spent on that over a P3 depends very
 much on what you do with the radio. I would probably go for the sub
 because
 it makes the K3 a much more powerful radio. If you're a DX-er, it's
 indispensable because it allows dual-watch. If you're a contester with the
 right kind of antennas (ideally, opposite polarity), Diversity reception
 can
 be an unbelievable upgrade to your station -- it was for mine. That said,
 I
 use a full-size 2-el 40m beam at 110' and a full-size 40m 4-square with 60
 radials per element. That combo had better be good! As has been noted,
 Diversity does require purchasing identical filters for all bandwidths
 with
 which you want to do Diversity reception. If you aren't a DX-er or a
 serious
 contester, then a sub might be less important and a P3 might make more
 sense
 for the dollars you have to spend.
 
 Hope this is helpful.

 Additionally, with a laptop/SDR-IQ combination I have a nice little

[Elecraft] [K3] Considering the second receiver and 6m preamp

2012-07-03 Thread Jim Lowman

Based on recent comments, it seems that I may well profit from ordering
the second receiver module for my K3.

Am I correct that I should also order the same filters (400 Hz/250 Hz, 
8-pole)
for the sub-receiver that I have in the main receiver?

[Elecraft] KX3 kit #543

2012-07-03 Thread Tony Estep

Well, I ordered on the morning of Dec 28 and finally got my kit #543
yesterday. Just as a final stinger, UPS announced that it would be
delivered last Friday and even marked it out for delivery on their site,
but the truck never made it and I had to wait over the weekend.

But all's well that ends well, and I now have it on the air. Started it
last night, finished this morning. When assembling this kit, one has to be
dazzled by the incredible amount of thought and ingenious engineering that
went into figuring out how all those goodies fit together. I have the
version with ATU and roofing filter, which makes things a little crowded
inside that box, but it all fits and is very elegant.

It hears my XG3 just fine, and I hear signals on the bands -- now for some
QSOs.

Re: [Elecraft] [K3] Considering the second receiver and 6m preamp

2012-07-03 Thread iain macdonnell - N6ML

I think it depends on what you want to use the sub-RX for. If it's
mainly for tracking split DX pileups, I think that the stock 2.7k
filter is probably quite sufficient, and fitting a full set of other
filters is nuts! I can see (some) narrow filters being of value for
someone who makes extensive use of diversity RX (with appropriate RX
antennas) in contest-type environments (crowded bands), though...

[Elecraft] OT - station pistol size

2012-07-03 Thread Robert G. Strickland

Hello, all...

I made a comment in another thread that my station was a little 
pistol. That got me thinking and wondering about how to size a ham 
station. Big Guns are rather obvious. Now, how about a small gun, a 
big pistol, a little pistol, and finally bow and arrow? Clearly, 
this is very subjective, For example, my station: in the city on a small 
lot, SkyHawk at 60ft, 80/40m compromise wires, nothing on 160m, 500w 
amp, and K3. I can jst get into the top 10 in the CQWWcw from WNY 
[most of the time], I've worked 335 DX on assorted bands, 5Band-DXCC is 
forever waiting on 80m, and it's generally hard to hold a run frequency 
when a band opens strongly. What size is this station? Anyone who comes 
up with pea shooter will be so noted g. How about your station? 
Happy 4th.

Re: [Elecraft] OT - station pistol size

2012-07-03 Thread Ron D'Eau Claire

My 1950's 6V6 xtal oscillator and now my KX1 or any rig whose power I crank
down becomes a feather weight station because I use it to tickle the
Aether. But QRP works better on CW.

When someone steps on my sig, I assume it's because they can't hear me (I
know there are other reasons, but I prefer to think the best of people) so I
QSY or, if I'm in a QSO, just work through or around them. That's an
opportunity to hone my copy skills through QRM. 

The last time I picked up a firearm was in the US Army. It's only function
was to wound or kill others. I prefer a gentler metaphor for my Ham rig.

[Elecraft] Considering the second receiver and 6m preamp

2012-07-03 Thread Erik Basilier

Having the same filters in both receivers, especially the cw filters, is a
good idea *if* you will use the second receiver for diversity reception.
However, I don't see why you would want both the 400 Hz and the 250 Hz
filters in any receiver, as the real bandwidth of these filters
(particularly the 250 Hz) is not close to the nominal numbers. In reality
these filters are so close in bandwidth that having both seems redundant for
most usage scenarios. If it were my rig, I would sell one of these filters
and use the proceeds to buy one filter for the second receiver.

 

73,

Erik K7TV

 

 

Based on recent comments, it seems that I may well profit from ordering the

Absolutely -- And remember that the receive bandwidth is *not* defined by
these filters. The bandwidth is established by the DSP filters. The crystal
filters come into play only if there is a signal so extremely strong that it
can overwhelm the DSP. The function of the crystal filters is to reduce the
strength of such a signal so that it can be handled by the DSP filters.

 and ran into a snag. I am not getting anything on two different frequency 
 counters when connected to TP3. Test up to this point have been good. Checked 
 all the components around X1 and all look correct. No error message on

Re: [Elecraft] Amplifier keying line delay setting

Howard,

Read the manual carefully - it says that the delay is the time for the 
receiver to *unmute* - it does not claim to extend the Keyout time.

Now, having said that, there is nothing wrong with appealing to Wayne 
and other designers to have it also apply to the Keyout timing.

Re: [Elecraft] K2 Alignment and Test, Part II - No signal on TP3

Cameron,

In order to calibrate the 4 MHz reference as stated, you must have a 
very accurate frequency counter (the first bullet), or you can listen 
with another calibrated receiver (2nd bullet), or you can just do as the 
3rd bullet indicates and set the C22 trimmer to center.  Whichever you 
use will not change the rest of your bringup of the K2.  When you have 
all bands working, I do encourage you to do a good dial frequency 
calibration - see my website www.w3fpr.com article for the procedure.

OK, now back to your problem.  I am not certain from your words, but I 
assume you read all zeros in the K2 display when you attempt CAL FCTR 
and the probe in TP3.  That may mean that the PLL reference oscillator 
is not working, or it could mean that your counter probe is not working.

If that is the case, try the probe in TP2 to see if you can read the BFO 
frequency.  If both TP2 and TP3 show all zeros, I would conclude that 
you have a faulty internal frequency probe or problems with Q9 and Q10 
on the Control Board.

If you have a good BFO frequency response at TP2, but all zeros at TP3, 
that means the PLL reference oscillator is not working.  Go to the 
schematic (RF Board sheet 1 of 4) and look in the upper left corner.  
The components shown there (over to but not including U4) are the ones 
you need to check for good soldering, and the diodes for proper 
orientation.  If you need help with diode orientation, look at the parts 
placement diagram in the back of the manual.  Then move on to the DC 
voltage measurements for Q19 to see if all looks well there.

You will need to get some reasonably proper frequency readout from TP3 
(The next and more important step is the PLL range which is the test in 
the right column).  That must be correct before moving on.

73,
Don W3FPR

[Elecraft] P3 TX Audio monitoring

2012-07-03 Thread Gary Gregory

*Well as nobody responded to my original post which identified a possible
issue with my station setup which allowed the P3 to display live TX audio
from the K3 I thought I would mention the subsequent test I tried.

1. Check that both BNC connectors were 'seated correctly'
2. Replace the Elecraft supplied BNC inter-connect cable
3. Relocate the P3 from it's position on the desk.

None of these appears to have resolved the issue..which does not disappoint
me one bit. After all, it IS a desired 'feature' for me.

It appears that if the P3 is placed on the left side and on top of the
KPA-500 there may be some 'leakage' getting into the P3 and showing up on
the P3 display as TX audio. This may be the root cause?

Whilst this does not happen on every transmission, and is not deliberately
repeatable, it does show up several times a day and I think it's rather
cool even if not consistent which would be even nicer.

I know many have asked for this to be a standard feature of the P3 and I
also note that Alan (N1AL) has stated this is not an easy option and I got
the impression it most likely would not be done in the near future...read
years?

For those of us with not so good hearing when it comes to the voice
spectrum, this is a way for us to check on our transmitted signal and not
need to wait for a negative comment or intrude on a QSO and inquire if our
TX audio is OK. Given the lack of operators who would be either unable to
give an accurate description of the audio, or indeed the sometimes abrupt
response received and in many cases the other station has tailored his
receive audio to best suit his/her hearing, I will take advantage of this
anomaly for now and enjoy it.

Thanks for the BW...:-)

Do you have any specific recommendation on how often one needs to take out
the NiMH batteries to balance them?

The KX3 battery holders are very solid (good) but I find it difficult to
remove the batteries, as significant force is needed. I have a set of NiMH
in there, and my default plan is to just leave them there for as long as
possible. I hope I can install the charger when it arrives without removing
the batteries. And, I am running on external power whenever I can, so that
the internal batteries won't need to be charged until the internal charger
arrives.

Re: [Elecraft] K2 Alignment and Test, Part II - No signal on TP3

Don,

Great advice. I wasn't able to construct the probe for the frequency counter; 
missing the capacitor in the kit, either lost it or wasn't included. 

I decided to use a external counter instead. Now, if I simply jumper P6 to T2 
and T3, I do get a reading, though sure its inaccurate, but reading 
nonetheless. I will email Elecraft for missing capacitor. In the interim, do 
you have a suggestion or replacement cap that will give same or near results 
until part comes in or another work-around?

Re: [Elecraft] P3 TX Audio monitoring

2012-07-03 Thread Guy Olinger K2AV

Wouldn't part of displaying the TX signal have to be implemented in the K3?
 If so it's a TWO box modification.  Fix the K3 to send the TX signal
across the connector to the P3 instead of the RX bandwidth.  Then the P3
would need to switch to the bandwidth needed to display the TX signal when
the K3 was in transmit.  This last because most of the time we are watching
on the P3 where we are NOT listening with the K3.

Some other way to do that?  73, Guy.

 3. Relocate the P3 from it's position on the desk.

 None of these appears to have resolved the issue..which does not disappoint
 me one bit. After all, it IS a desired 'feature' for me.

 It appears that if the P3 is placed on the left side and on top of the
 KPA-500 there may be some 'leakage' getting into the P3 and showing up on
 the P3 display as TX audio. This may be the root cause?

 Whilst this does not happen on every transmission, and is not deliberately
 repeatable, it does show up several times a day and I think it's rather
 cool even if not consistent which would be even nicer.

 I know many have asked for this to be a standard feature of the P3 and I
 also note that Alan (N1AL) has stated this is not an easy option and I got
 the impression it most likely would not be done in the near future...read
 years?

 For those of us with not so good hearing when it comes to the voice
 spectrum, this is a way for us to check on our transmitted signal and not
 need to wait for a negative comment or intrude on a QSO and inquire if our
 TX audio is OK. Given the lack of operators who would be either unable to
 give an accurate description of the audio, or indeed the sometimes abrupt
 response received and in many cases the other station has tailored his
 receive audio to best suit his/her hearing, I will take advantage of this
 anomaly for now and enjoy it.

 Thanks for the BW...:-)

Re: [Elecraft] OT - station pistol size

 Hello, all...

 I made a comment in another thread that my station was a little
 pistol. That got me thinking and wondering about how to size a ham
 station. Big Guns are rather obvious. Now, how about a small gun, a
 big pistol, a little pistol, and finally bow and arrow? Clearly,
 this is very subjective, For example, my station: in the city on a small
 lot, SkyHawk at 60ft, 80/40m compromise wires, nothing on 160m, 500w
 amp, and K3. I can jst get into the top 10 in the CQWWcw from WNY
 [most of the time], I've worked 335 DX on assorted bands, 5Band-DXCC is
 forever waiting on 80m, and it's generally hard to hold a run frequency
 when a band opens strongly. What size is this station? Anyone who comes
 up with pea shooter will be so noted g. How about your station?
 Happy 4th.

Re: [Elecraft] K2 Alignment and Test, Part II - No signal on TP3

Cameron,

Yes, do get the capacitor for the probe, you will need it for your 
filter alignment even if you do not choose to follow my instructions for 
achieving good K2 Dial Calibration.  Any 10 pF capacitor will do, but 
the axial one is better physically - it fits nicely under the heat 
shrink.  I have a few counter probes with lumps because I substituted 
10 pF disc ceramics for the axial capacitors.  Note that I lose probes 
often - or more correctly, I leave them in my customer's K2s, so when I 
ger down to a qwuantity of one, I build another from whatever materials 
I have at hand - there is no magic it is just a shielded wire with a 
10 pF capacitor at the probe end. BTW, a #14 AWG wire fits the probe 
sockets very nicely if you are inclined toward building your own probe 
tip.  A small amount of grinding/filing will round the tip.

Just jumpering between CB P6 and RF board TP2 or TP3 can lead to 
erroneous readings because any DC present is not being blocked, and that 
can skew the readings.

If you have an external frequency counter, you can move on to the PLL 
range tests and the BFO range tests using the external counter rather 
than the internal one.  Don't worry about the 4 MHZ reference for now 
(it may end up being slightly different than exactly 4.0 MHZ) - just set 
the trimmer slot as indicated by bullet 3.

 Don,

 Great advice. I wasn't able to construct the probe for the frequency counter; 
 missing the capacitor in the kit, either lost it or wasn't included.

 I decided to use a external counter instead. Now, if I simply jumper P6 to T2 
 and T3, I do get a reading, though sure its inaccurate, but reading 
 nonetheless. I will email Elecraft for missing capacitor. In the interim, do 
 you have a suggestion or replacement cap that will give same or near results 
 until part comes in or another work-around?

 Read my last post carefully.  Then tell us whether you are seeing all
 zeros when plugged into TP3 and in CAL FCTR.  If you have all zeros,
 either your probe is bad or your PLL reference is not oscillating.

Re: [Elecraft] KX3 interal battery charger

Dan,

Let me start with a smart comment - not all things in life are easy.

The batteries should be hard to remove because of the spring tension - 
if it were easy, than the contact pressure would be questionable.

As far as your fingers aging, while that may be true, I don't think that 
is a major factor here - it just makes plain sense to have adequate 
spring pressure on the battery contacts.

 Do you have any specific recommendation on how often one needs to take out
 the NiMH batteries to balance them?

 The KX3 battery holders are very solid (good) but I find it difficult to
 remove the batteries, as significant force is needed. I have a set of NiMH
 in there, and my default plan is to just leave them there for as long as
 possible. I hope I can install the charger when it arrives without removing
 the batteries. And, I am running on external power whenever I can, so that
 the internal batteries won't need to be charged until the internal charger
 arrives.

Re: [Elecraft] P3 TX Audio monitoring

Guy,

That would still only give a picture of the K3 output as found by the IF 
leak-through signal.  I think a better approach is to wait until the 
external sensor is developed and released - that will show the real 
signal going out to the antenna.

On 7/3/2012 9:55 PM, Guy Olinger K2AV wrote:
 Wouldn't part of displaying the TX signal have to be implemented in the K3?
   If so it's a TWO box modification.  Fix the K3 to send the TX signal
 across the connector to the P3 instead of the RX bandwidth.  Then the P3
 would need to switch to the bandwidth needed to display the TX signal when
 the K3 was in transmit.  This last because most of the time we are watching
 on the P3 where we are NOT listening with the K3.

 Some other way to do that?  73, Guy.

Re: [Elecraft] KX3 interal battery charger

2012-07-03 Thread Daniel B. Curtis

Thanks Don,
The two batteries inside each holder are easy to take out. The two
batteries on the outside of each holder are more difficult. It is not a
function of the spring tension ... Probably assuming the spring tension is
the same for each battery, it is the shape of the holder.

That said, the fix is to put a silk ribbon under the outside batteries ...
As has been suggested.

[Elecraft] K2 CAT Command Question

2012-07-03 Thread Tom KG3V

I am trying to change the INP Menu setting on a remotely-operated K2. It is
currently in the Paddle-reverse mode, and I need to change it to HAND.
Looking at the K2 Programmer's Reference Manual, It looks like I can send
SW41;UP; or SW41;SW01; to do this. When I send these commands using Han
Radio Deluxe, I get an [error] returned and the value does not change.

Can anyone see a mistake in my commands? Probably missing something obvious.

 Date: Mon, 02 Jul 2012 10:07:08 -0700
 
 Hi Gary,
 
 The P3 is supposed to blank the screen whenever the K3 goes into
 transmit mode.  If that's not happening then it sounds like there must
 be an RS-232 communications problem between the K3 and P3.  One
 possibility is if you have some third-party software program running
 on the PC that is overloading the RS-232 capacity by sending large
 volumes of commands to the K3.  For example Ham Radio Deluxe is known
 to do that, depending on its settings.
 
 If you want to see the IF leakage during transmit you can do that by
 disconnecting the RS-232 cable.  Another way is to change the Xcvr
 Sel menu selection to 8215 kHz (inverted) instead of K3.
 
 I've been resisting making that an official feature because it really
 isn't very reliable.  It depends on random leakage through the mixer
 and PIN diode switches in the K3, which are unspecified.  It also
 varies with band and transmit power level and may result in too small
 a signal to be useful under some conditions.
 
 The plan is to include a modulation monitor function with the future
 external power sensor option.  I've had the hardware done for months
 but have been too busy with the SVGA development to have time to do
 the firmware.  Real Soon Now.  :=)

Re: [Elecraft] K2 CAT Command Question

Tom,

It may be an HRD problem or a problem with a USB to serial adapter. What 
happens if you issue the command with K3 Utility terminal page.  That 
will tell you whether to look toward the K3 for the solution or toward HRD.

Are you running HRD through LP-Bridge?   If so, that is another possible 
block.  90% of the K3 commands work through LP-Bridge, but not all - 
this may be one of them (I really don't know, I am just guessing).

[Elecraft] KX3 Amp keying

2012-07-03 Thread Sid Leben

In a much earlier question I had asked Wayne if the KX3 would be able to key 
the Juma PA100D amplifier. He responded with a yes..
I tried it today with a cable from KX3 ACC2 to the T/R input on the Juma amp.  
Yes it did key the amp, but when connected there was an appreciable receive 
loss on the KX3.  I am guessing, but in the order of 20-30db.

What am I missing here ?  I'll take another look at it tomorrow…
