Re: [Elecraft] [KAT500] Help with KeyLine Interrupt on KPA500 (Video)

[Igor Sokolov]

I think what happens is KAT500 needs few msec to determine the operating 
frequency and measure SWR. There is currently no delay between PTT going 
into KAT500 from the radio and PTT going out into the KPA500. These few msec 
is enough for KPA500 to switch itself to fault condition.
Here programmable PTT delay in KAT500 would be very helpful. Especially so 
with other makes of the amplifiers.
I have discussed it with Elecraft tech support and they say this feature is 
on their to do list. Lets hope that the next firmware revision of KAT500 
will have that feature implemented.

[Elecraft] [KAT500] Cabling Diagram

[Richard Ferch]

Roy,

Why are you using the figure on page 6? That is only needed if you have 
an external device that controls the key line (the box at the top right 
corner in the figure on p.6). If you don't have such a device, the 
applicable configuration is the figure on p. 4. With only the K3, KPA500 
and KAT500 you do not need to use the RCA cables at all, because PTT 
control is already provided on pin 10 of the DB15 cables.


If you do have an external device that needs to have PTT control (the 
box in the upper right corner of the figure on p.6), you must use the 
key line interrupter in the DB15 line to allow the external device to 
control PTT (see note on p.5). Without the key line interrupter, the PTT 
will be switched by the DB15 cables without regard for what the external 
box requires.


I am using the connections from p.4 (no RCA cables), and it is working 
fine, with a couple of caveats.


First, and from your description I suspect this may be your problem: 
Although I had used CONFIG:TUN PWR = 25 in the K3 with the KPA500 off in 
order to "train" the KAT500 for my antennas on all frequency segments, 
once I was finished the initial training process I had to set CONFIG:TUN 
PWR back to NOR before using the KPA500. The reason: On some bands, TUN 
PWR of 25W is too much drive for the KPA500, so if I held the XMIT 
button on the K3, i.e. used TUNE on the K3 with the KPA500 in OPERATE, 
the amp would trip on those bands. Make sure the TUN PWR on your K3 is 
either set to NOR, or else is set lower than the lowest driving power 
you use with your KPA500 on any band, in order to avoid tripping the amp 
on bands that don't require high driving power.


The other caveat is to wait for a second or so after switching either 
the band or Operate/Standby on the KPA500, to allow everything to 
settle. If you change from standby to operate and start transmitting too 
quickly, the K3 may not have had time to react to the operate/standby 
signal from the KPA500 and change its power level before you start 
transmitting.


You also need to have CONFIG:PWR SET on the K3 set to Per Band in order 
for power control of the K3 by the KPA500 to work properly.


73,
Rich VE3KI

I have connected the cables as shown on page 6 of the KAT500 Automatic Antenna 
Tuner Owner's Manual, revision B3, November 20, 2012. I am connecting the K3, 
KPA500 and KAT500 using the DB15 interface cables and the two RCA (yellow end) 
cables for the separate key line. This diagram shows the key line interrupter 
inserted between the DB15 cable and the K3 ACC socket. I have not inserted the 
key line interrupter, and the system seems to work fine. However, I DO have to 
change the KPA500 from OPERATE to STANDBY when changing frequency because 
leaving it in the OPERATE position may cause the amp to FAULT when I hold the 
XMIT button on the K3. I believe the tuner is trying to search with high power. 
I wonder if inserting my key line interrupter would prevent this. All 
frequencies had been previously memorized by the KAT500. Thanks. Roy Morris

[Elecraft] K3 V4.61 CW decode broken?

[Brian Alsop]

Was checking out RTTY decode which worked fine.  Decided to look at CW 
decode.


Here are my observations.

Not working well here or op here inept at using it.

My perception is that it did much better in older versions.  However, I 
didn't use it much then.


ZL9HM was 599 @35 wpm this AM.  WPM check always showing between 48 and 
82 wpm. Decode with WPM check off was bunch of E's and T's.  Not due to 
noise.


Using 400 Hz filter in CW mode.  Tried auto, both choices for speed, 
auto, different thresholds.  Closest to working is auto.


Similar problem with C6AKQ at 32 wpm when decoding some characters right.

Both stations generating machine generated CW.

I'm also thinking that these stations are using "contest" spacing of 
characters which may be confounding. In WINKEY and N1MM the word spacing 
for contest spacing is 6 dits/wordspace instead of normal 7.


Admittedly these are really short exchanges and the time to lock on is 
really short.  However, my guess is that these are the exact conditions 
some guys are using the decoder for.


A longer rag chewing K9 at 28wpm did decode OK but was not spectacular. 
Although his signal was strong, characters were dropped.  He seemed to 
be using normal spaced CW.


I'm wondering is "contest spacing" is confounding for the decoder.

Re: [Elecraft] Found this on Facebook this morning... KPA800??

[wa5pok]

These early amp prototypes were a real learning experience for us. Our 
staff did an excellent job, and they worked very well. However, after 
sizing up the costs and risks, we decided to enter the market with 
something smaller (K3-size) featuring a zero-noise (linear) power  supply 
based on a toroidal transformer. 500-600 W seemed like an ideal  target, 
and there you have it: the KPA500.


I certainly wouldn't rule out other amps in the future.


The majority of my operating, contesting and DXing is at the 100 watt level 
with my K3. BUT on 80 and 160 (even though I easily got WAC with 100 watts 
on 160) there are times that the 1000 or 1500 watts on 160 is needed. It may 
not be due to propagation but sometime ya just gotta have the smash to punch 
through the other guy's noise to get that QSO. Thus I have an AL1500 on the 
table that sees rare usage but its there when I need it.


I would rather have a quality Elecraft there. My 2 cents.

Re: [Elecraft] Arm Chair Settings for the K3

[Don Wilhelm]

Sherrill,

I believe you are asking about the AGC settings.  If so, know that the 
settings are dependent on your local noise levels.  I suggest you create 
your own.
Use the information in the "Noisy K3" article on my website 
(www.w3fpr.com) as a guideline.
That article was written before the AGC menu parameters were expanded, 
but the principles are the same.  That information will allow you to set 
the parameters that best suit your local noise level and your operating 
desires.

[Elecraft] (OT) Begali "Adventure" Paddle Update

[stan levandowski]

For those with interest, I just received the following info  from Ulrich 
N2DE/DJ8GO:


"Just received Adventure 001 and Adventure Mono 001.  Absolutely
fantastic! The "feel" is considerably improved over the prototypes,
and the gold plating, stainless steel, and unique finger pieces add to
the impression of a key which represents the absolute pinnacle.  I am
working on the website (www.I2rtf.com) now, trying to capture and 
describe this little

marvel.  I am sure you will be delighted with the Adventure Mono which
will go out to you sometime next week.

The line is more than 30 long already, ordered without knowing the 
price.


The dual lever will be (in Euros as usual) 248, the Mono 258, there
will be mounting brackets for the KX3, the KX1, and the FT817 at 28,
and a small magnetic desktop base for 33 ...  [ yes, you can pass all 
this

along]  73, Ulrich"

Re: [Elecraft] K3 V4.61 CW decode broken?

[Wayne Burdick]

Brian,

Virtually all other reports on this release have said the CW decoder  
was working very well. I just retested this morning, too.


If you're seeing E's and T's, try using a much narrower bandwidth,  
50-150 Hz, and turn on the noise blanker to reduce the level of  
impulse noise. I recommend using THR 2 or 3 for most signals, and THR  
1 for very weak signals. These fixed settings usually work better than  
AUTO.


When there is no CW signal above the required threshold, you'll see  
random characters decoded.

Another demo of the well known fact that a 50-100w light bulb load with filament 
aligned with the correct magnetic field declination for the particular QTH will 
entrain polar field ions and function as a 4-el monobander. People are always 
forgetting this effect and spending money on big yagis, trying to recapture the light 
bulb ion effect. Old timers are useful for keeping this type of info available for

Re: [Elecraft] Are you satisfied with your K3?

[Phil Hystad]

I thought everyone knew about 100-watt light bulbs.  Back in my Novice days 
about 50 years ago, it seemed that all of my other Novice friends all used 
100-watt light bulbs as a dummy load for test & tune-up.  And, we got used to 
the idea of hearing each other in the area because we all operated with the 
around the same frequency cut crystals so we often all ended up on the same 
spot on 40 meters.  When I was a Novice, 40 meters was the only band I worked 
since those were the only crystals I had.  And, I am not an old-timer.  An 
old-timer is always someone older than me -- Always!

Re: [Elecraft] [KAT500] Help with KeyLine Interrupt on KPA500 (Video)

[Eric Swartz - WA6HHQ, Elecraft]

Make sure you are only routing the AMP keying line from the rig through 
the KAT 500 to the amp. The tuner always interrupts this line when it is 
tuning.  This can be done either via the the AMP keying line RCA 
connectors on the Rig, KAT500 and the AMP, or via the KPAK3AUX cable 
connections between the K3 and KAT500 and between the KAT500 and the 
KPA500 when the K3 is used.


Some customers have hooked up the AMP keying line to the amp two ways in 
parallel. One correctly through the KAT500 to the amp (usually via the 
KPAK3AUX cable), and the other incorrectly via a second path directly 
from the Rig's Key out RCA connector directly to the amp.  This second 
path will nullify the KAT500's attempt to open the AMP keying line to 
theMAP during tune.

Re: [Elecraft] [KAT500] Help with KeyLine Interrupt on KPA500 (Video)

[iain macdonnell - N6ML]

It should be noted that the KAT500 does not "regenerate" the PTT
signal, rather it (only) interrupts it (by opening relay contacts).
Therefore it can't really delay the initial PTT signal going to the
amp... it can only interrupt it as fast as it can, when it detects
high VSWR.

As Gary mentioned, there is newer KPA500 firmware that alleviates the
problem of hard faults when it detects high VSWR before the KAT500 has
time to interrupt the keying line, but it appears that that new KPA500
firmware has not been generally released yet.

Re: [Elecraft] [KAT500] Help with KeyLine Interrupt on KPA500 (Video)

[hawley, charles j jr]

So with the new firmware the KPA500 would tolerate a high VSWR for a few more 
milliseconds to give the tuner time to interrupt keying? 
I was thinking of ways to not send a keying line with the K3 when using "tune". 
But this doesn't seem possible with the K3...I take it the PTT is used

I deal with turning the KPA to standby now anyway for the MFJ 998 tuner, so I'm

doesn't mind a little non-hard fault, so much the better.

[Elecraft] Big weakness in Macro's

[W0SD Ed Gray]

IMHO there is a big need for a command that can be use to define things 
back to the same state. One big rule in programming is you always set 
the state of things so you are always dealing with a known starting 
point. The command structure in the K3 does not permit this.


A number of things in the K3 are toggle, for example in MIC SEL 1 
toggles the mic back and forth from high to low and 2 toggles for bias 
on or no bias.  There are a number of other instances of this in the K3.


Not having a command to define things back to the same state, lets call 
it a default or reset state makes the programming commands in the K3 
pretty weak IMHO.

Re: [Elecraft] [KAT500] Cabling Diagram

[Roy Morris]

Thanks to all who responded to my questions regarding tuning the KAT500 when 
the KPA500 is in OPERATE mode.  Changing CONFIG: TUN PWR back to NOR and 
reducing K3 PWR has helped to keep the amp from tripping to STANDBY from 
OPERATE when changing frequency within the same band.  Occasionally the 
fault light might come on, but the amp does not trip to STANDBY.  Holding 
the K3 TUNE button a second time will cause a click and clears the fault 
condition.  The KAT500 is then ready to operate.
I have removed the RCA cables and find they are not necessary in my case. 
Thanks again to all for the help.  Roy Morris  W4WFB

[Barry Middleton]

My I thank all at Elecraft for making this Ham's Christmas even happier, 
I ordered a KX3-K, KXAT3, KXBC3, KXFL3, MH3 and for the K2/10 FDimp, 
K160RX, KAF2 and KNB2on Monday 3rd December. I could hardly believe it 
when a driver from UPS delivered a box from Elecraft today Friday 7th 
Decemberat 12.30 UTC. I really was not expecting it until after 
Christmas, well done everybody. Yes it looks as if I have drunk the 
Elecraft Koolaid, I am hooked. May I wish everybody on this list a very 
happy Christmas.

Re: [Elecraft] [KAT500] Help with KeyLine Interrupt on KPA500 (Video)

[Chris Johnson]

Hi Eric,

I do not have the AUX cable.  As described in the video, I am only using the 
RCA cable from the Flex 3000 into the KAT500 and then another cable from the 
KAT500 down to the KPA500.

I am not using this with a K3 radio, which in that case,  would only use the 
AUX cable and no RCA Key Line.

Re: [Elecraft] KAT500 remote operation

[ab2tc]

Hello again,

I finally managed to get the B&B software to work and I am now in full
control of the box from the shack using the utility. Wonderful. I tried the
"fine tune" method to improve the SWR on some 80m frequencies, but don't
seem to able to make it work. Am I supposed to continue with uninterrupted
20W carrier when I click on the tune button again? It never seems to want to
improve the settings any.

Re: [Elecraft] KAT500 remote operation

[Eric Swartz WA6HHQ - Elecraft]

Stop tx after the first tune. Then quickly press the tune button on the KAT500 
and the immediately go back into TX. That will enter the fine tune mode.

Yes. It may still kick in the attenuator temporarily, but it shouldn't
hard-fault.

I used a MFJ-998 before I got the KAT500 too. I had the KPA500
configured to switch to standby mode on band-change, then I'd transmit
a bit to get the MFJ to tune, then put the KPA500 in Operate. I
operated the KAT500 that way at first too (during early field-test),
but since the firmware for both KAT500 and KPA500 have matured, I've
turned off the option to standby-on-band-change on the KPA500, and
have been happily QSYing around with no resulting hard faults.

Re: [Elecraft] [KAT500] Help with KeyLine Interrupt on KPA500 (Video)

[Igor Sokolov]

That may be cure for KPA500 + KAT500 combo but KAT500 supposed to work with 
amps of other manufacturers. My conversation with Elecraft tech support led 
me to believe that some sort of TX delay can be implemented in future 
firmware release.

It should be noted that the KAT500 does not "regenerate" the PTT
signal, rather it (only) interrupts it (by opening relay contacts).
Therefore it can't really delay the initial PTT signal going to the
amp... it can only interrupt it as fast as it can, when it detects
high VSWR.

As Gary mentioned, there is newer KPA500 firmware that alleviates the
problem of hard faults when it detects high VSWR before the KAT500 has
time to interrupt the keying line, but it appears that that new KPA500
firmware has not been generally released yet.

Re: [Elecraft] Big weakness in Macro's

[Matthew Zilmer]

A while back, I wrote a CW functional test for the K3.  In doing this, I ran 
straight into the programming problems cited earlier by Ed.  My solution wasn't 
very innovative or elegant (not being involved in the firmware development at 
all), but it was adequate and met the requirements.

After establishing comm and getting control of the K3, the I would poll the 
toggle and multi-value states parameters that could be set by the program.  
There was a list of 25 or so controls of this type, and I would just add new 
ones as needed.  The really fun part was reading back the values.  I had to 
dump the VFO A or VFO B displays to do it.  I took my cue from Dick Dievendorf, 
assuming he'd done something like this to read back the RTC time in the Set 
Date and Time tab on the K3 Utility.

Having the MN and MP commands saved a lot of effort as above, but the 
implementation is partial.  That is not all MN parameters can be polled or set. 
 So displaying parameters' toggle or multi-value state is about the only way, 
in the general case.

For a multi-value parameter (TEXT DEC is one I had to use a lot!), dialing 
through all the values is a little cumbersome and requires as many functions  
to get/set as the number of parameters that are used.  OTOH, there are probably 
many MN parameters that would never be used by a hosted program and I believe 
that's why Wayne decided to implement the ones that were obviously needed or 
perhaps only those that were requested by software developers.

At the start of the program, I'd store all the toggles and multi-value 
parameters that the program could touch.  When exiting back to Windows, the app 
would restore these, including the initial baud rate.  The idea was to leave 
the K3 in the same exact state before and after.

I would guess the best argument for having a known default state is from Ed.  
But executing such a command would introduce a bit of entropy, meaning the K3 
would end up in a different state from what it was when the hosted program was 
started.  This might be ... disturbing ... to users, and disruptive to using 
the K3 without having to manually restore a bunch of parameters' states.

IMHO there is a big need for a command that can be use to define things back to 
the same state. One big rule in programming is you always set the state of 
things so you are always dealing with a known starting point. The command 
structure in the K3 does not permit this.

A number of things in the K3 are toggle, for example in MIC SEL 1 toggles the 
mic back and forth from high to low and 2 toggles for bias on or no bias.  
There are a number of other instances of this in the K3.

Not having a command to define things back to the same state, lets call it a 
default or reset state makes the programming commands in the K3 pretty weak 
IMHO.

Re: [Elecraft] Are you satisfied with your K3?

For pure nostalga, OT's and those wondering what signals sounded like in the
50's might really enjoy this video:

I'd forgotten the delight of watching the blinking gas in an over-worked 807
final in a CW xmtr.

I don't know that I'd say it's more fun now, but it sure is different.

Hello Chris,
Your video shows what I am experiencing also.  Firmware v.1.15 seems to have

Re: [Elecraft] KAT500 remote operation

[ab2tc]

Hi,

Still can't manage to get any improvement doing this. Anyway, right now the
tuner is doing a great job to my G5RV on all bands except 15m and 80m. For
those bands the raw SWR is above 12:1 so is outside the design parameters
for the tuner. These are screen shots for the bands where the tuner is
finding a good match:

I'll continue to work on the 15m and 80m to see if I can improve it.

Re: [Elecraft] Big weakness in Macro's

[Mike Markowski]

It's crossed my mind from time to time when tackling issues like that 
how nice it would be to have an Elecraft MIB and SNMP control.  Think of 
all the commercial & open source software and libraries that would 
instantly be available.  It's always easy to daydream when you're not 
doing the work...  :-)

[Elecraft] K3 - spurious signal.

[Fred Jensen]

Getting started in the ARRL 10, I discovered a weakish signal on the P3 
15 KHz below the VFO A cursor that moves when I tune A.  Ref level is 
-125dBm, signal is about -110dBm.  I don't remember ever seeing it 
before.  15KHz is suspicious, I don't see it on other bands.  Hope all 
is OK with my K3.

Re: [Elecraft] KAT500 remote operation

[Don Wilhelm]

Knut,

You might try adding or subtracting feedline at the shack end of the 
feedline to bring the SWR down on those bands.  I would suggest 
experimenting with an antenna analyzer rather than the tuner - you will 
be able to see which way to go for making improvement.


The fact is that the feedline with SWR will act as an impedance 
transformer, and it will be more of a transformer on bands with high SWR 
than on the bands that are better matched.


Some experimentation may be in order.

Re: [Elecraft] K3 - spurious signal.

[Fred Jensen]

Perhaps it's a full moon tonight, about the only explanation I can come 
up with.  There were actually two of them, +/- 15KHz from where I was 
tuned.  They were annoying since they moved when I tuned, and made 
interesting pictures on the P3 waterfall since they were strong enough. 
 I have never seen them before.


I'm going to do an SOHP CW in the ARRL 10, but I switched VFO's just to 
see if there were any stations on phone.  Came back to CW for awhile, 
and then realized the spurs were gone.  We'll see if they reappear 
tomorrow morning.

Fred, that's a birdie. As long as it's outside of your passband it will

if your noise level is low enough and you look closely with a sufficient

[Elecraft] NAQCC Sprint Tuesday night!

[NAQCC]

NAQCC Sprint Tuesday night!

Our December sprint is this coming Tuesday evening local time (December 11, EST 
- 8:30-10:30PM, CST - 7:30-9:30PM, MST - 6:30-8:30PM, PST - 5:30-7:30PM), which 
translates as Wednesday December 12, 0130-0330Z in all cases.

I will refer you to the proper URL:

http://naqcc.info/sprint201212.html

There you will find all the details as to time, frequencies and other important 
information.

Certificates: SWA (simple wire antennas) certificates by call area, VE and DX 
for 1st, 2nd and 3rd place finishers (New!).  A Certificate for top score in 
the GAIN antenna category.

Prizes:  Too many to list!! - We're making a change in our prize drawing for 
the sprints.  Here's a quote from the prizes page, under the main section, on 
the web site:
"Beginning with the November 2012 sprint, a winner will be notified as soon as 
one is chosen.  Then the first to reply gets the first choice of a prize. 
Before that we went by order of sprints.  In other words, the June winner had 
to wait for the May winner to make his choice, etc.  Now it's first response, 
first choice no matter what month.  That way those who take forever to answer 
won't hold up those who are eager to get their prize.  If someone doesn't reply 
at all by the end of the following month, there will be a re-drawing to choose 
a replacement winner for that sprint, and the one who didn't reply becomes 
ineligible for any future drawings.  For example, the June winner has until the 
end of July to respond."

This is a monthly event that caters to the CW veteran, the CW newcomer, 
straight key and bug fans.  All are welcome to participate (this includes QRO); 
but you must use QRP power levels to compete for awards.

If you are not already a member of NAQCC... membership is FREE!  Now is your 
chance to join the largest QRP CW Club in the world!!  We currently have 6340+ 
members in: All 50 States - 9 VE Provinces - 90 Countries.  Just sign up on the 
NAQCC website (http://naqcc.info/) and you will receive a handsome certificate, 
with your membership number which is good for life.

Come join us and have a real good time!

[Elecraft] [K3] K3 Util can't connect to serial port

[Paul A. Thompson]

I have been unable to connect to my K3 through the serial port using either
1) 9 pin RS-232 cable direct to laptop serial port or 2) USB to serial port
(FTDI) adapter on either the laptop USB port (running XP) or on the new
Windows 7 desktop machine (no serial ports, so only using the USB).  My K3
is sn 2096, MCU FW is 4.39 and I just downloaded (several times) the K3
Utility from elecraft.com.  When I try to connect to the port (Test Conn),
it runs through all the speeds, and won't ever find the K3.  I have also
tried Hyperterm, and the only remnant of communication I get with it is when
the speed is matched up to the PC port speed (Device manager) = K3 RS-232
speed [Config menu], I see a triangle for each  Q I type.  Nothing
else does anything.  If speed isn't matched, I don't even get that.

 

Any other ideas to try?  The port has worked in the past.  New computer +
latest HRD version since I last used the RS-232 port though, and with the
latest firmware changes, I am anxious to get things working again!!   I do
have an RS-232 9 port M-F with LEDs that should help diagnose any voltage
problem with the port, I hope.

 

Thanks for any help you guys can lend.  I did look through posts, but not
finding much applying to this situation.. 

 

73,

Paul N5PT
