Re: [Elecraft] KPA1500

[K5MWR via Elecraft]

I was pretty certain that shipments would start this week.  I just left 
on a 4 week ski trip so naturally Murphy prevails and shipments start 
while away :).


Has anyone received a shipping verification email, as I undertood 
Elecraft was going to contact each person to verify the order and make 
sure of shipping prior to orders going out.

Re: [Elecraft] KAT500 actual radiated power during tuning

[K5MWR via Elecraft]

A technique that works well using a dummy load to adjust a tuner is to 
set up a bridge configuration where the dummy load absorbs the power and 
the tuner is used to balance the bridge.  Once done the dummy load is 
switched out and rig drives the tuner.  Electric Radio use to sell a 
bridge like this that I have used with my Drake amps for years and 
really nice way to minimize QRM.

Erik,

I don't know the workings of the Icom tuner, but the KAT500 needs 20 
watts input to tune.  All of that goes to the antenna.


If part of that signal would be shunted to a dummy load, I don't think 
it would be tuned to the correct antenna impedance.
I would have to know more about the configuration involved, but to my 
mind, it sounds like a dummy load is being connected in parallel with 
the antenna which would upset the impedance to be matched.

Erik,

The KAT500 relies on the transceiver power being reduced when tuning.
I am not certain how (or if) that happens with an Icom transceiver, 
but the KAT500 needs about 20 watts for reliable tuning.
That can happen automatically with the K3/K3S/KPA500 combination, but 
I don't know what the Icom can do to accommodate that same thing.

antenna, is the KAT500 comparable?

[Elecraft] Norton and P3 Utility

[K5MWR via Elecraft]

Don't know if anyone else has experienced this but this morning I get 
this message from Norton that the P3utility program is a threat named 
"Heur.AdvML.C" and that P3Utility.exe has been removed.


Don't know if the recent major upgrade of Windows had any effect or most 
likely it is due to the low number of P3Utility users that also have 
Norton installed as they show less than 100 users.


Expect this is just another of those cases where Norton is flagging 
because of few users so just going to reload.


Pasted below is the Norton explanation.  No need to flame Norton, I 
understand its peculiarities just posted for information only.

Re: [Elecraft] P3 Phase noise/HighSignal Response?

[K5MWR via Elecraft]

Jim

Really appreciate this information and going over it now to make sure I 
understand the limits.  The presentation is well done.


How did you capture the SVGA images?

Hi Dave,

The P3 is quite good for measurements, and the SVGA card is even 
better.  Here's a collection of work I've done with whatever rigs and 
amps I could get my hands on to measure.


http://k9yc.com/P3_Spectrum_Measurements.pdf

In my experience, if you keep the K3 within its linear region, you'll 
get good data from the P3 if you understand the measurements you're 
making.  Limitations -- the dynamic range is 100 dB, but you can only 
display 80 dB on screen. For all of the operation I do, I use the P3 
with a lot of averaging and a slow waterfall, fairly large waterfall.  
For measurements, I use the P3 in Peak reading mode and let it 
accumulate peaks for a while. I make the amplitude display pretty 
large, set it for 80 dB, and adjust levels to fill the amplitude screen.


When I'm checking CW bandwidth, I send a series of dits in the range 
of 35 WPM for at least 20 seconds I reset the peak a second or so 
after I've started sending dits so I don't see any initial transient 
that might be present. Notice that I set the span for a fairly narrow 
bandwidth.


The annotations you see for bandwidth are obtained by moving the 
cursor to each data point and writing down the readings, and they are 
the DIFFERENCE between the high and low points.


If you want to show data more than 80 dB below the peak of the signal, 
you can repeat the measurement with the reference level reduced by 20 
dB.  More than that and the P3 will overload.

Re: [Elecraft] VOX/PTT select macro ?

Bill

Exactly the problem I have.  I would be happy with either a SET VXn 
command or the VOX state was mode dependent, SET VXn would be my preference.


I am using 5.7 also and VOX is constant not mode dependent.

Bob, if we are missing something in the config or menu settings that 
does make VOX mode dependent please let me know.  Will not be the first 
time I have overlooked an obvious solutions :)


Mean time guess the old Mark 1 eyeball must be employed to verify :)

automatically turn VOX on or OFF (exception:  VOX ON is ignored for some

I just upgraded my firmware from 5.5 to 5.7 and the VOX setting 
remains the same when I switch between SSB and Data.

[Elecraft] VOX/PTT select macro ?

[K5MWR via Elecraft]

At one point in the macro command reference there was a statement that 
VOX/PTT selection would be available through a direct macro command.  
Currently all I am able to make work is the SWT or SWH type command 
which is basically of no use since there is no way to know what the 
current mode is.  Has anyone found a work-around for this?

Thanks

Re: [Elecraft] P3 and Centering the Display

[K5MWR via Elecraft]

Sean

Apologies as I did not read your full post when I sent the earlier response.

I too see the same type of response and need to execute an involved 
macro multiple times in order to get it to fully function.  Depends on 
what frequency/band and mode I am starting with.  I would like to have a 
macro to take me to a digital mode such as JT65 using something like below.


BN03;FA7076000;MD6;DT0;PC020;BW0400;FT0;SB0;SWH09;#MKA1;#MFA+7077000;#MKB1;#MFB+7078000;#SPN50;#CTF+7077750;

My understanding is that the time to execute band or large frequency 
changes in indeterminate and that there is no simple pause command that 
can be inserted to allow the steps to complete.
I also find that the inability to know what mode such as VOX/PTT you are 
in causes problems.  There was mention at one time that a VOX command 
was to be implemented but have not seen that.

I was wondering if anyone has come up with a macro that will (reliably) move
the P3 to a frequency (K3 VFO A) and center that frequency on the display?

  


I have a P3 w/ SVGA. I am using the latest firmware(MCU 1.60; SVGA 1.34;
FPGA 1.04). I am testing macros using the latest P3 utility(1.16.3.15)
Command Tester. (FYI - I live in Fixed Tune Mode.)

  


Consider the following scenario: Three macros that each move (FA) to 2.5
MHz, 5.0 MHz, and 10.0 MHz respectively and then center the display (#CTF or
#CTF 0 or #RCF 0 or #FXT0;#FXT1; or even just an FA again).

  


(And yes, I do have more useful needs for this, but this seems like a simple
example.)

  


Execute them one after the other.

  


After each macro, I am always left with the Frequency Cursor at the left
edge of the P3 display which is the desired frequency and now defined as the
P3 "Center Frequency" as displayed in the middle of the top edge of the
display (this is also the frequency indicated at the left of the top edge of
the display, the "Lower Frequency Limit").

  


If I execute the same macro a second time I am centered on the display just
fine. The breakdown seems to occur if I am commanding a new frequency which
is not within some range of the current P3 display. IE. - Going from 2.5 MHz
to 5.0 MHz fails but from 2.706 MHz to 2.5 MHz works.

  


(Bulletin! - Extensive (!) testing has shown that the 2.5 MHz macro will
work properly if the starting frequency is in the range of 100KHz - 2.999
MHz; the 5.0 MHz macro will work properly in the starting frequency range of
4.800 - 5.999 MHz; and the 10 MHz macro will work properly in the starting
frequency range of 9.000 - 22.999 MHz.)

I think that (from K3 relay noises) those boundaries coincide with some band
filter switching. I have no idea what that means.

  


I have tried every command combination that I can think of to no avail.

  


Breaking the macro into separate components works fine.

  


But it would be nice to accomplish this without having to execute two
separate macros.

  


Of course the internal programming of the P3 is a black box to me, but the
behavior suggests that it may be a timing issue for the macro execution. It
is as if, after executing the FA command, the centering commands are still
seeing  the previous frequency and falling back on the default behavior of
parking at the left edge of the display whenever it thinks that it is being
commanded out of the range of the current P3 display. Even though it isn't.

  


But that may just be a fantasy I have created in my own mind!

  


I am happy to entertain any suggestions. Keep in mind that the manual would
make you think that several options should work just fine but the execution
isn't so copacetic. You might want to try things out with the Utility's
Command Tester. Maybe my understanding of what should be possible needs
realignment.  ;)

  


Or perhaps I should just resign myself to the reality that it doesn't work
the way I want it to and move on!  :)

  


Thanks for any hints or tips.

After each macro, I am always left with the Frequency Cursor at the left
edge of the P3 display which is the desired frequency and now defined as the
P3 "Center Frequency" as displayed in the middle of the top edge of the
display (this is also the frequency indicated at the left of the top edge of
the display, the "Lower Frequency Limit").

  


If I execute the same macro a second time I am centered on the display just
fine. The breakdown seems to occur if I am commanding a new frequency which
is not within some range of the current P3 display. IE. - Going from 2.5 MHz
to 5.0 MHz fails but from 2.706 MHz to 2.5 MHz works.

  


(Bulletin! - Extensive (!) testing has shown that the 2.5 MHz macro will
work properly if the starting frequency is in the range of 100KHz - 2.999
MHz; the 5.0 MHz macro will work properly in the starting frequency range of
4.800 - 5.999 MHz; and the 10 MHz macro will work properly in the starting
frequency range of 9.000 - 22.999 MHz.)

I think that (from K3 relay noises) those boundaries coincide with some band
filter switching. I have no idea what that means.

  


I have tried every command combination that I can think of to no avail.

  


Breaking the macro into separate components works fine.

  


But it would be nice to accomplish this without having to execute two
separate macros.

  


Of course the internal programming of the P3 is a black box to me, but the
behavior suggests that it may be a timing issue for the macro execution. It
is as if, after executing the FA command, the centering commands are still
seeing  the previous frequency and falling back on the default behavior of
parking at the left edge of the display whenever it thinks that it is being
commanded out of the range of the current P3 display. Even though it isn't.

  


But that may just be a fantasy I have created in my own mind!

  


I am happy to entertain any suggestions. Keep in mind that the manual would
make you think that several options should work just fine but the execution
isn't so copacetic. You might want to try things out with the Utility's
Command Tester. Maybe my understanding of what should be possible needs
realignment.  ;)

  


Or perhaps I should just resign myself to the reality that it doesn't work
the way I want it to and move on!  :)

  


Thanks for any hints or tips.

Re: [Elecraft] Keyboards for P3/SVGA

[K5MWR via Elecraft]

I use a wireless keyboard made by TECKNET that works fine.  You plug in 
the wireless adapter to the USB port on the P3 or PX3 and your set.

I am about to buy one.  Anyone have advice about a readily available make & 
model that does work well?

Thanks in advance,

[Elecraft] Macro delay help

[K5MWR via Elecraft]

Admittedly a neophyte in learning the ins and outs of writing macros so 
forgive if this question has already been addressed.


I am trying to place macros in the P3 SVGA memories and have run into 
the problem that appears the K3 response time for doing band changes is 
preventing the ability to write a complex macro.  Is there a way to 
insert delays into the macro to allow band change (possibly other 
functions) to complete?


An example of what I am trying to do is below where a band change at the 
start results in having to run the macro twice to work.  It depends on 
what prior band was in use.  My desire is to switch from other 
bands/modes to specific operating frequencies and have the P3 span and 
center freq be specific.

Appreciate any pointers.
