[Elecraft] [KPA500] Pushing an amplifier

[Al Lorona]

Many of us would feel a psychological edge if we pushed an amplifier such as 
the KPA500 from its rated 500 W to, say, 625 W. It sounds like so much more, 
doesn't it? It sure makes us feel better to think that we're louder on the 
other end.

But first, on your S-meter take a look at the width of one S-unit, which is 
commonly held to be 6 dB. Now imagine that single S-unit divided into six equal 
parts, each of them 1 dB.

If you have an analog S-meter the needle is probably wider than one of these 
parts. Do you think you could hear a difference if a signal increased (or 
decreased) by one of these skinny little 1 dB increments?

Well, the increase from 500 to 625 Watts is a little bit *less* than one of 
these increments.

Furthermore, especially if you're on phone, the increase in in-band intermod 
that results from pushing any amp may actually subtract a little bit of 
intelligibility from your SSB signal. I don't know what the dB equivalent of 
this "intelligibility loss" would be... but what if it's like 0.5 dB? It's 
simply not worth it.

If you ever want to calculate for yourself the dB change from an increase or 
decrease in power one place you can find the equations (as well as a link to an 
on-line calculator) is here:

http://www.radio-electronics.com/info/formulae/decibels/decibel-formulae-equation.php
 .

Someone will say, "But when your signal's right under the noise floor on 160 
CW, that extra 0.9691 dB might help." I agree in advance-- to save you the 
trouble of having to point out that rare situation. For the rest of us, the 
conservatively rated output of the KPA500 should be just fine.

Re: [Elecraft] K3/P3/expert 1.3KA

[Igor Sokolov]

Not all of Expert 1.3 are sold with internal antenna tuner. There are 
amps without it. If I were in Jerry's situation I would purchase 
internal antenna tuner from Expert for the sake of integration and speed.

Why an automatic tuner?  The amp has an auto-tuner, and the two are 
unlikely to play well together. Instead, I'd look at a good manual 
tuner like the Ten Tec 238. I've owned several of them and find them 
to be good performers. So did ARRL Labs when they tested them many 
years ago.


Ten Tec has been sold a couple of times and new 238s are probably no 
longer available, but used 238s are usually available on the used 
market. Best bet are the B and C models, which have a vernier readout 
for the inductor, as opposed to a dial cord in the older models. 
Expect to pay about $400 for the B or C, $300-350 for the older 
units.  The 229 is electrically and mechanically the same as the older 
238s, but in a cabinet that matches older Ten Tec rigs.


To use this tuner in your station, set the SPE to bypass mode, tune it 
for the bands where you operate and log the settings. Then put the SPE 
tuner back in line in auto mode and let the auto tuner do its thing to 
cover the band(s) as you QSY.

Hi Don,

This is what I'm currently doing. I need an additional RS232 output in
addition to the connection to the PC for an external device that needs to
track the vfo frequency of the KX3. I'd like to have the PC able to track
what frequency/control what frequency my radio is tuned to, and at the same
time have my external device also tracking the frequency the KX3 is tuned
to. I apologize for being less than clear. :)

David,

The LP-Bridge application has an output that you can set up which will 
send some information to another serial port on the computer.  See the 
LP-Bridge documentation at www.telepostinc.com.

Re: [Elecraft] K3: past chirp report

[Ron D'Eau Claire]

Any time I work a station that has a less-than-normal signal I say so. Some are 
running vintage rigs from the WWII era in which a little drift and chirp are 
normal which usually results in a long rag-chew about the rig since I, too, 
love vintage gear. Among the others, I don't know if any of them ignored me but 
everyone said they greatly appreciated my report.

Re: [Elecraft] Any ideas on how to run serial (DB9) and USBserial at the same time?

[Don Wilhelm]

David,

The solution for the KX3 and KXPA100 is greatly simplified if you use 
the KX3 to KXPA100 adapter cable.
You connect the KXPA100 to the personal computer and the adapter cable 
splits out the RS-232 signalling to the KX3.  See the connections on 
page 14 of the KXPA100 manual.  The KX3USB cable connects between the 
KXPA100 and the PC.


No MAGIC BOX needed.

The PX3 does not have to be continuously connected to the computer.  For 
firmware updates, Configuration Save and Restore, you can connect a 
KX3USB cable and run the PX3 Utility for those operations (those are 
done off-line and not real-time).

Don W3FPR

Why an automatic tuner?  The amp has an auto-tuner, and the two are 
unlikely to play well together. Instead, I'd look at a good manual tuner 
like the Ten Tec 238. I've owned several of them and find them to be 
good performers. So did ARRL Labs when they tested them many years ago.


Ten Tec has been sold a couple of times and new 238s are probably no 
longer available, but used 238s are usually available on the used 
market. Best bet are the B and C models, which have a vernier readout 
for the inductor, as opposed to a dial cord in the older models. Expect 
to pay about $400 for the B or C, $300-350 for the older units.  The 229 
is electrically and mechanically the same as the older 238s, but in a 
cabinet that matches older Ten Tec rigs.


To use this tuner in your station, set the SPE to bypass mode, tune it 
for the bands where you operate and log the settings. Then put the SPE 
tuner back in line in auto mode and let the auto tuner do its thing to 
cover the band(s) as you QSY.

Re: [Elecraft] K3: past chirp report

[Wayne Burdick]

This is not a factor in synthesizer switching. Both the old and new synths 
incorporate their own voltage regulators, preserve identical signal integrity 
down to a power supply voltage of around 9 VDC. That's about as low as the 
radio can go in any case.

2) that's too much of a drop. Running 40 watts out to drive my Alpha
8410, the voltage is 14.1 key up and 13.9 key down reading from the
transceiver display. 3) 40 watt current draw is 10.8 amps.

You should run your power supply at 14.2 volts out, use a short cord to the K3S.

[Elecraft] K3/P3/expert 1.3KA

[Jerry Muller via Elecraft]

I have a question?
I have a K-3/P-3 with a Expert 1.3 k amp. Due to the low swr cut off point  
of the Expert amp (1.7) and the high swr of my antenna (2.3) I am  looking 
for a Antenna Tuner. I have selected a Palstar HF Auto. My question is  what 
will the Expert amp do when the tuner is tuning. I was under the  
impression that since the connection between the K3/P3 and the amp and the 
tuner  are 
all 50 ohms, and there fore a 1:1 swr the amp  would see a match  of 1:1 
and there would be no reduction in power due to the antenna  mismatch. Is this 
correct.

Re: [Elecraft] K3: past chirp report

[Wayne Burdick]

Under normal circumstances, it is impossible for a K3 or K3S for exhibit 
"chirp." The synthesizer settles well before the rig switches from TX to RX or 
vice-versa. 

The KSYN3A (newer synth, used in the K3S) settles in well under 1 ms thanks to 
its entirely digital architecture (UHF DSPLL, divided down). 

The KSYN3 (older synth, used on the K3) uses a more traditional PLL with its 
VCO running at the target output frequency. It normally settles in under 5 ms. 
It can take a bit longer depending on the actual PLL voltage and VCO frequency. 
This is accounted for in firmware. 

If your KSYN3 were not properly calibrated, you might see a longer settling 
time on one or two bands, most likely 6 meters. If you suspect this, refer to 
the CONFIG:VCO MD menu entry. The K3 includes an automatic VCO calibration 
routine that requires no test equipment and takes only a couple of minutes to 
run.

Re: [Elecraft] Source for K3 weighted knobs

[Ron D'Eau Claire]

"Broccoli Bands" - the wide rubber bands many grocers use to hold bunches of
veggies like broccoli together - were very popular on the K2 knob and worked
very, very well. 

But they did not seem to be exotic (or expensive) enough for many. 

Unfortunately, the ones I have are a bit too large for the K3 VFO B knob.
Thanks for the suggestion. 

It's all in what makes a Ham happy.

Re: [Elecraft] K3: past chirp report

[ab2tc]

Hi,

My remarks to bulleted items below:

1) Sounds good.
2) Where are these voltages measured? If they are measured outside the K3
with an accurate DVM, I would say they are marginal. If so, raise the key up
voltage to 14.2V. If they are measured by the K3S' internal voltmeter they
might be OK.
3) That's way high. My K3S draws no more than 17A at full 100W out. 

I can't really comment on the other bullets. I have heard other reports of
K3 chirps that turn out to be nothing more than hearsay.

Re: [Elecraft] K3: past chirp report

[Ron D'Eau Claire]

In a synthesized VFO rig like the K3S, any tendency to "chirp" is almost always 
related to the synthesizer momentarily losing frequency (or phase) lock. 

While that could conceivably be linked to change in the power bus voltage, it's 
highly unlikely since the bus is isolated from the actual synthesizer by 
voltage regulators and filters.

OTOH, the OO's report was strictly advisory. I have experienced spurious OO 
reports over my >50 years of pounding brass, and one that turned out to be 
accurate when I blew the filter caps in the transmitter and did not notice, nor 
did the stations I was working report the hum on my signal. When I got a 
"chirp" report one time (on a homebrew rig) and was unable to hear it myself, I 
sent a friendly letter to the OO. He replied that he was "almost sure" he could 
detect a "slight chirp" so he sent the card. 

So my advice is that if you can't repeat what the OO observed, don't worry 
about it.

Subject: Re: [Elecraft] K3: past chirp report

Yup, that was me.

There were some good suggestions made here and I’ve checked them all and I’m 
unable to get the K3S to chirp.  So, at present: unable to replicate..

Some of the suggested things I’ve checked:

1) SWR at the K3S while driving the ACOM 1500 (same operating conditions) is 
1.05 to 1.  SWR between the ACOM and the antenna at the noted frequency is 1.2 
to 1.

2) Voltage at the K3S is 13.8 key up and 13.2 key down; seems OK.  Power supply 
is a switcher which I’ve used for some years.

3) K3S is drawing 21.96 amps key down.  (Not running 100 watts into the amp.)

4) I’ve intentionally “mis-tuned” the amp just in case that is what was going 
on when the OO noticed the chirp.  I did this by tuning up properly at 14.001 
and then QSYing to 14.083 and transmitting while monitoring with a different 
receiver.  No chirp, clicks or other anomalies.  This is a much worse operating 
condition than I normally encounter.  It’s so easy to tune the ACOM that I keep 
it properly tweaked.  Also, I was operating in CW SS and in the middle of a 2 
hour run when the OO heard me chirping and I have a tough time imagining that 
I’d sit on a given frequency for two hours without making sure I was properly 
tuned.

5) I do not use ALC between the K3S and the ACOM.  I do run with specific power 
levels on each band (great feature, BTW) such that I’m not able to overdrive 
the amp.

6) I’ve checked my in-the-shack coax jumper cables and I don’t see any issues.  
The antenna end of the coax is currently under 2 feet of snow so I haven’t 
looked at it.  But, I’m getting normal SWR readings here in the shack.  There 
isn’t any arcing going on or the amp would shut down.  No RF in the shack; no 
TVI or other issues in the house.

7) I recently made 535 QSO’s in NAQP CW and did quite a bit of listening on a 
second receiver, never heard a chirp.  I wasn’t using the ACOM so I ran the K3S 
at 100 watts.  And, finally, I have not yet received another OO report after 
the NAQP.;-)

I dunno what to think.  The issue remains unresolved but I am unable to 
replicate the problem.

I just bought on LULU system the new Fred book about macros.I was waiting it 
anxiously, becouse I had programmed some macros, at first only on PF1-PF2-M1-M2 
on my K3S, and, after that  I bought a K-POD, on this last great accessory. 
Used it for split, unsplit, full power and lower power for amp, two different 
settings for AGC THR, continuously changing if filters.I have just opened the 
pdf book, it seem really a great work.I want to make better use of K-POD, i 
hope it will help me.73 de Ian IK4EWX

Re: [Elecraft] K3: past chirp report

[Doug Smith]

Yup, that was me.

There were some good suggestions made here and I’ve checked them all and I’m 
unable to get the K3S to chirp.  So, at present: unable to replicate..

Some of the suggested things I’ve checked:

1) SWR at the K3S while driving the ACOM 1500 (same operating conditions) is 
1.05 to 1.  SWR between the ACOM and the antenna at the noted frequency is 1.2 
to 1.

2) Voltage at the K3S is 13.8 key up and 13.2 key down; seems OK.  Power supply 
is a switcher which I’ve used for some years.

3) K3S is drawing 21.96 amps key down.  (Not running 100 watts into the amp.)

4) I’ve intentionally “mis-tuned” the amp just in case that is what was going 
on when the OO noticed the chirp.  I did this by tuning up properly at 14.001 
and then QSYing to 14.083 and transmitting while monitoring with a different 
receiver.  No chirp, clicks or other anomalies.  This is a much worse operating 
condition than I normally encounter.  It’s so easy to tune the ACOM that I keep 
it properly tweaked.  Also, I was operating in CW SS and in the middle of a 2 
hour run when the OO heard me chirping and I have a tough time imagining that 
I’d sit on a given frequency for two hours without making sure I was properly 
tuned.

5) I do not use ALC between the K3S and the ACOM.  I do run with specific power 
levels on each band (great feature, BTW) such that I’m not able to overdrive 
the amp.

6) I’ve checked my in-the-shack coax jumper cables and I don’t see any issues.  
The antenna end of the coax is currently under 2 feet of snow so I haven’t 
looked at it.  But, I’m getting normal SWR readings here in the shack.  There 
isn’t any arcing going on or the amp would shut down.  No RF in the shack; no 
TVI or other issues in the house.

7) I recently made 535 QSO’s in NAQP CW and did quite a bit of listening on a 
second receiver, never heard a chirp.  I wasn’t using the ACOM so I ran the K3S 
at 100 watts.  And, finally, I have not yet received another OO report after 
the NAQP.;-)

I dunno what to think.  The issue remains unresolved but I am unable to 
replicate the problem.

HI Jim,

I use my KX3 for JT65, JT9, MSK144, and WSPR (in addition to PSK31 and lots of 
CW) - all the settings are the same on the KX3, other than the power output, 
which I change to meet band conditions. On WSPR I usually run it at 2 watts; 
MSK144 on 6 meters it runs 100 watts with the KXPA100.

Re: [Elecraft] K2/10 Low power

[Don Wilhelm]

Byron,

OK on the DC voltages.  You may have to resort to measuring the RF 
voltages as indicated in Appendix E of the manual - Transmit Signal 
Tracing to find where the failure might be.


Check the value of R98 on the bottom of the RF board.  The fact that the 
maximum power drops off significantly on the higher bands tells me that 
the value of R98 could be greater than the stock value of 270 ohms.


What happens to the voltage at RF Board U9 pin 3 when you do a TUNE?  It 
should drop to 1/2 the value that it has during receive.  If not, Q20 is 
not working properly.


For your 160 meter problem - is C153 68pF?  Also is C68 10pF (if you 
have an older K2, it may be 4.7pF.


On the irregular behavior of the POWER knob, it could be a worn pot - 
look at the power displayed as you turn the knob - it should be smooth. 
If it is, my suspicion lies with the value of R98.  Remember that the 
VALC voltage is what actually controls the drive to the TX Mixer, and 
the value of R98 is a controlling factor in the power control loop damping.
If this K2 had the KPA100 installed and the power output went up and 
down during transmission, the fix is to increase the value of R98 - some 
builders went too far with the increase resulting in low power on the 
higher bands and possibly 160 meters.

Don,

 As you suggested I checked all the voltages in the Elecraft manual on the
RF board. All are good...

Here is the  (MAX) power (OUT) int a dummy load on each band and I noticed
something  that was peculiar.

10m = 2 watts
12m = 2 watts
15m = 3.5 watts
17m = 4 watts
20m = 5 watts
30m = 10 watts
40m = 12 watts
80m = 12 watts
160m = 4 - 5 watts

I notice while on 40 meters that as I decrease the power setting the power
out peaks a tiny bit at he 12 oclock position to 13 watts  and doesnt start
decreasing until I get to 10 oclock and as I turn powerback up after I get
past 12 oclock the max power drops off by 1 watt.

What do I test or change next?  is my driver transistor at fault, just not
driving the finals???

Trying to get this resolved before the  CQ 160 Meter CW Contest on the
27th, need a true 5 watts during the contest and to not harm my rig during
the event.

Re: [Elecraft] Source for K3 weighted knobs

[Bill]

Looks like the secret is out now. Very careful layering of several 
slices of the bicycle inner tube - together with careful trimming - will 
not only provide a great feel - the looks will also be good. Same method 
can be applied to other rig's VFO knobs. Also good for outdoor water 
faucets.

Both the stock VFO A knob and VFO B knob are weighted. The VFO A knob also has 
a soft-touch rubber ring.

I have to admit I'm a little baffled as to why any different knobs would be 
desirable. We tried to optimize for both function and aesthetics. But hey, I'm

Re: [Elecraft] K2 on 60m (K60XV)

Heinz,

Note that the date on that application note was before the K60XV was 
available.
Also not the first paragraph which states that this is only for 
experimental use.
The release of the K60XV took away the need to do any of the 
modifications stated in that application note.

Hi Don and Leif@LA3ZH,

Thanks for clarification!

The question arised since I had not considered this matter before 01.01.2017
(no allocation in HB9) and now by reading this:
http://www.elecraft.com/Apps/k2on60.htm
The technical imperfections explicitly mentioned by this document are no
longer explicitly addressed by the actual K60XV manual - so, was not sure if
still valid or obsolete.

So there seems to be no reason not to add 60m to my very proven band
monitoring station (K2/P3/7.5m active loop).

73, Heinz HB9BCB

Re: [Elecraft] OT(sorta) Setting up KX3 for JT9 ops

[Don Wilhelm]

Jim,

JTx is no different than any other soundcard data mode.
Use DATA A
Set the audio input to the KX3 so you have 4 bars solid on the ALC meter 
with the 5th bar flashing.  Once you have the audio level set, leave it 
that way.

Control the power output with the POWER knob.
Ignore the advice in the JTx information and on the internet to control 
the power with the audio level - that is for non-Elecraft transceivers.


Any differences in the various soundcard data modes will be found in the 
software application used, not in the KX3 setup.

Re: [Elecraft] [K3] WTB:KAT500

[Petr, OK1RP/M0SIS]

Hello,

thank you very much for forwarded link with selling the KAT500 arrived from
one of the subscriber over here on list. Unfortunately CONUS only again. So
no deal. Still looking for this used unit to complete my station. Maybe if
someone in EU is thinking about selling it as "no more used" or so...

Thank you for tips or offers.

[Elecraft] [K2] KAT2 sometimes no output and error E216 or E232 :: serialno. 4037

[Frank Talens]

-- Elecraft K2/10 with KAT2 error :: serialno. 4037 --

Hello,

Sometimes my KAT2 built-in antenna tuning unit gives erroneous behaviour. It 
goes like this:

Normally nothing is wrong. Nor in ATU AUTO mode nor in ATU CALS mode. But 
sometimes after using the KAT2 auto-tuner (setting ATU AUTO) there's no RF 
signal on the ANT1/ANT2 sockets and the SWR reading is infinite. Yes, when I 
check on the original "Antenna 50 Ohm"-socket there IS signal but nothing comes 
out of the ANT1 (or -in case selected- ANT2) socket. In some cases I'm able to 
recover the normal desirable behavour bij disconnecting the KAT2 unit from the 
RF-board and reconnect.

There really are times there's nothing wrong with the ATU and I'm able to tune 
different loads on different bands. But all of the sudden the error kicks in 
again.

When the error has happened I can get an error-code from the KAT2 settings menu.
Normally (when error-free operating) the error code is E000
In case of error it gives E216 or E232, depending on whether de ATU is in mode 
AUTO or CALS.

What things do I have to check / where is my error likely to exist?

Regards,

Frank Talens PF5T

Re: [Elecraft] K3 ERR DSE

[Tony G6GLP]

To don and all others,
I didnt even have to call or mail K3support but I have the response 
already.  I have reloaded the firmware now on MC 5.56 the DSP is the 
same but got reloaded anyway. The problem would seem to be overwork of 
the CPU and this seems to fit with my recollection that it only seems to 
occur when I have the pc connected. The response from Gary was:-

*
That error can occur if there are a lot of things going on at the same 
time, such as CAT control is being used with a computer and NR or NB are 
enabled. It is a report of excessive traffic to/from the K3 MCU.


Try turning things off that are not absolutely necessary, and/or reduce 
the polling interval between the PC and the K3.

*
My thanks to all who replied especially K3support i.e. Eric for 
forwarding the mail and Gary and Don for there appropriate responses.

Tony,

ERR DSE says that there was a missing echo from a DSP command - see 
page 68 in the K3 manual.  The first level of "fix" is to reload the 
DSP1 (and DSP2 firmware if applicable).


If the problem continues, yes, contact K3support for further assistance.

Hi All,

Some weeks ago now I installed the 5.54 MCU beta to use with the K-POD I
have not had any problems until the last couple of days when I
intermittently get a ERR DSE E 04004C.


What does the E 04004C mean?


Factual answers please or do I have to contact K3support?

Re: [Elecraft] K2 on 60m (K60XV)

Hi Don and Leif@LA3ZH,

Thanks for clarification!

The question arised since I had not considered this matter before 01.01.2017
(no allocation in HB9) and now by reading this:
http://www.elecraft.com/Apps/k2on60.htm
The technical imperfections explicitly mentioned by this document are no
longer explicitly addressed by the actual K60XV manual - so, was not sure if
still valid or obsolete.

So there seems to be no reason not to add 60m to my very proven band
monitoring station (K2/P3/7.5m active loop).

73, Heinz HB9BCB
