Re: [Elecraft] KAT500 Problem

[Rick NK7I]

Using the utility, erase the settings for 20M and reteach it? Once 
trained, leave it in MAN mode for daily use.

Re: [Elecraft] KAT500 no PC comms

[Mike / K5JR]

Indeed, Andy is correct. The Elecraft serial is STEREO and the Icom is MONO. 

I reversed them in my mind and didn’t verify which was which before posting. 

The main point behind this was to highlight that the two were not 
interchangeable.

The plug has to connect data in, data out, and ground.  That requires 3 
contacts which cannot be done with a mono plug!

The KAT500 PC DATA port uses a STEREO plug.

Re: [Elecraft] KAT500 no PC comms

[Chuck Chandler]

Two things I've noted with my KAT500 PC comms that you might want to
quickly check:

1.  More than once I've forgotten to stop the "KAT500 Remote" app before
running the KAT500 Utility app.  Since the Remote app is using the com
port, it has to be stopped first.
2. That plug in the rear of the KAT500 can get partially unplugged with one
more "click" needed to seat it fully and make it work.  If that is the
case, neither the Remote or Utility apps will be working.

These have both caught me a few times, hope it is one of them since they
are a quick fix.

Re: [Elecraft] KAT500 no PC comms

[Mike / K5JR]

My KXUSB cable suddenly went QRT a few months ago necessitating getting a 
replacement. I initially thought the chip on the board had blown up, but it was 
OK. I verified that everything was still good by throwing together a temporary 
fix with a USB to 9 pin serial cable and a matching 9 pin to *MONO* cable. The 
KAT serial port is MONO, not STEREO, as I (not so quickly) discovered, 
prompting the time distracting blown chip theory/investigation mentioned above.

Right. That's what I've been using since I bought the KAT500. The utility 
program does not connect to the KAT at any speed on COM3, which is what Windows 
assigns when I plug the KXUSB into the PC.

Re: [Elecraft] KAT500 no PC comms

[Dave New, N8SBE]

I had purchased a used KAT500 from someone that it turns out had bought 
it from a 'super station', but had never tried to update the firmware or 
use the KAT500 utility to talk to the KAT500.  After I got it home, I 
tried to check the firmware level, only to find out that I could see the 
prompt from the KAT500, but I couldn't talk to it.  It turned out that 
the FET in the input side of the PC DATA jack was blown, likely from 
static charge at the 'super station' and they had sold the KAT500 to my 
intermediate owner without telling him it had a blown PC DATA port.  I 
asked Elecraft support for the part number for the FET, ordered a few 
from Mouser, and replaced it (it's an SMD device, so not for the faint 
of heart) and that cured the communication issue.


Of course, your mileage may vary.

There is a 3.5mm stereo jack on the back of the KAT500 labeled 'PC 
Data'.  You need an Elecraft KXUSB cable, which is the same USB to 
serial cable used on the KX2, to talk to the KAT500 from your PC.


Unlink the KUSB, which has a USB A connector on one end, and a 9-pin 
serial connector on the other, the KXUSB has a USB A connector on one 
end, and a 3.5mm stereo plug on the other, so there are only 3 
connections - GND, RX, and TX.


Hope that helps,

With a K4, does the KAT communicate with the PC via the K4's USB

Re: [Elecraft] KAT500 no PC comms

[Jack Brindle via Elecraft]

The KAT500 does not use the same cable as the K3 or K4 or, for that matter, the 
KPA500. It needs a cable with stereo mini-phone connector. Elecraft has a USB 
cable that plugs into the KAT500 and works quite well.

Re: [Elecraft] KAT500 Sleep current?

[G4GNX]

Interesting to note that there is no “Idle” button in your image. I guess 
that’s elsewhere in the utility.

I would assume that as they’ve used the word “Power” in the utility, I’d expect 
it to be the same as the power button on the front panel of the KAT500. From 
what you’re saying, it certainly seems to act that way.

My setup has the KAT500 power up when the shack PSU is turned on, but I always 
hold the power button on the KAT500 when I turn the radio/s off and of course 
all of the LEDs go off.

MY setup is all hard wired so I can’t easily get a meter inline to check 
current consumption when the KAT500 is ‘off’. I don’t have consumption issues, 
as all of my power is turned off when I leave the shack.

Sorry I can’t be of much help.

I think it does more than shutdown the oscillator. It seems to turn off all

Re: [Elecraft] KAT500?

[Rick Bates, nk7i]

Eugene,

The KAT500 will work with almost any radio made in the last 40 years (or 
somewhat older), presuming the rig has I/O data available. If it doesn't 
read the band data from the radio ( on it's ACC port), there are still 
plenty of ways to allow it to do what it needs to do.  The utility is 
one feature that allows finer control or management.  But the KAT500 is 
serial port only for control purposes.  It doesn't have an ethernet or 
wifi system.


The following presumes that you have a serial (or other) port on the 
radio for it's control and this answer may be longer than you expect.


In the longer run (larger picture as your station develops), you'll want 
more than control of your KAT500.  You'll want to be able to log, manage 
mode changes, band/freq changes (rig control), turn your rotor, switch 
antenna ports on the rig or KAT500 and myriad assorted other necessary 
items.  Not all of the pieces are IP control but require USB or serial 
ports, like the KAT500.


You'll find that it's all much simpler to dedicate a computer (from 
Raspberry Pi, Arduino up to a full fledged top line gaming system) to 
manage the station tasks, hardware and software; even if you're sitting 
there able to mash buttons.  Simple just ROCKS and lowers the ... 
moments when things get busy or distracted and the brain makes mistakes 
(it protects you, a little).


I did that (ALL station elements managed) and it runs quite easily.  
Then I ran the station equally as well, by operating the computer that 
runs the station, remotely.  Two factors present a challenge, an 
adequate audio path for phone/cw, and latency (the time it takes to get 
from the radio to your ears, ad vice versa, no matter the path).  
(Remote can be across the room or anywhere with internet.)


I chose and use TeamViewer for computer control and Skype for audio.  
(Like most hams, I'm cheap and those apps are free and available on many 
platforms which gives a LOT of options from phone, tablet or another 
computer.)  Plus your contact log entries are (correctly) from the 
station, not where you happen to be. I've run my stations while 
traveling much of NA and HI while on road trips and it's still fun and a 
great way to keep in touch with the local gang.


Depending on the OS of your choice, there are many options to choose 
from.  Windows has FAR more options for the moment, the rig control app 
of your choice, a good logging program (integrated suites do much of 
these), KAT500 utility (check/verify readings and override choices if 
more than one antenna), amp control if you have one (KPA500 or KPA1500 
utility apps), rotor and antenna management (PSTrotator with the SteppIR 
functions) and if you want, an IP power switch for shutting it all down 
and/or rebooting. (A remote power on for the K3 or K4, when off, they 
are OFF.)


If you are a knob turner ham or a mouse clicker (or both), running the 
station is much easier when you integrate all of the aspects on one 
screen.  It allows quicker band changes (QSY and everything follows 
along) and a wealth of information on the screen, as well as the 
hardware displays.  You watch ONE place (the display), less movement 
required (except your eyes).


Wanna make a couple quick contacts from work during your lunch break or 
while visiting family for the holidays?  Now you know how.


Only have a tiny closet for the actual station hardware but no where to 
put the operating chair?  Now you can operate it remotely (be careful 
about heat removal in this case).


For now, you're working on the KAT500 with the utility; expand beyond 
that over time and integrate everything.  That means look at what you 
want the station to accomplish for you.  Wise choices now makes it 
simpler later as you integrate more.


And the answer to your question is yes, you'll want something to manage 
the KAT500 app, all the time.  But it must be via it's serial port.


Think bigger, go beyond.

Re: [Elecraft] KAT500?

[Rick Tavan]

I use KAT500 Utility remotely by running it on a small, inexpensive server
computer at the remote station and displaying and controlling it via Chrome
Remote Desktop. (There are several equivalent remote desktop programs.)
Note that you can not run KAT500 Utility and KAT500 Remote Server at the
same time because they both use the one serial port into the KAT500 device.

This arrangement has been completely satisfactory for me because the
settings I make with Utility endure for many months, only occasionally
changing in response to antenna changes. In fact, since I am there at the
remote site when changing antennas, I rarely need to operate Utility
remotely. But I certainly can. KAT500 Remote is the control point in use
when actually operating on the air with KAT500.

Excellent. thank you. I’ve been advised that I should download the kat500 
utility and look in the help files for more details since, as you point out, 
without a KAT500 the software will limit my ability to comb through the 
features.
Thanks all!

Generally, I am wondering if the software supports:

  1.  Setting the SWR threshold --  below which, the tuner will consider a 
tuning solution to be "done"
Yes - See Configuration tab, SWR Thresholds
  2.  Once the tuning solution is found, the manual changing the L's and C's to

Yes - See Operate tab, Capacitance and Inductance adjusters.
  3.  Settings for which antenna should be used for which bands
Yes - See Configuration tab, Antennas
  4.  Can an antenna be set for use with multiple bands (like OCF dipole)? Or 
only one band per antenna?
Yes, any antenna port can be assigned to any bands 160-6 via individual check 
boxes or All. See Configuration tab, Antennas.

Re: [Elecraft] KAT500 beta 2.16

[Andy Durbin]

"Based on the release notes, I think this means that the Yaesu FTDX3000 (and 
others)  can operate in enhanced mode, like the Kenwood, with both frequency 
and band data.  Is that correct?  If so, what kind of cabling is needed for the 
Yaesu for enhanced mode?  Can enhanced mode function if another device (pc 
running MacLogger via USB) is also polling?"

My direct experience is limited to Kenwood TS-590S but I think Yaesu rigs can 
be interface with KAT500 and KPA500 in a similar way.

KAT500 never requests data and is configured as a passive RS-232 receiver.  For 
KAT500 to receive any useful data something else must be polling the rig and 
the KAT500 listens to the rig's replies.  For  a station using KPA500 and 
KAT500 the typical source of the polling is the KPA500 which, when Serial rig 
type is selected, polls a connected rig with IF, FA, and FB commands.  KPA500 
uses the rig responses to derive band.  If KAT500 is listening to the rig 
responses using a suitable Y cable then it extracts the rig's TX frequency from 
the IF, FA, and FB data words. (KPA500 only cares about band.  KAT500 needs 
frequency with 1 kHz resolution.)

The KPA500 does not have to be the polling source.  Any application that 
includes IF, FA, and FB in its rig command sequence can be used.  The required 
cable would have rig RS-232 receiver connected to KPA500 (or PC application) 
RS-232 transmitter.  The rig's RS-232 transmitter would be fanned out to 
KPA500, KAT500, and if applicable a PC applications RS-232 receiver.   (Caution 
- only one transmitter is wired in this cable).

That's the basic idea.  The average hoarder could assemble the cable for next 
to no cost.  Elecraft sells a cable for Kenwood and perhaps also one for Yuesu).

Re: [Elecraft] KAT500: Not remembering antenna configuration

[JK Hooper via Elecraft]

Hi all, 

Here is an update on my KAT500 Mac software utility problem, described below. 

I am able to configure my KAT500 just fine with the Windows version of the 
KAT500 Utility using Windows 10 O/S, so, effectively, my “problem” of 
configuring the KAT500 is solved.   

The Mac version of the KAT500 utility does not appear to be working correctly 
with macOS Ventura 13.2.1, at least on my computer.  

I have let Elecraft support know.  

Special thanks to Andy K3WYC who emailed me quite a few times with suggestions 
on troubleshooting and he pointed the way for me to track things down.

Any insights on troubleshooting approaches for my KAT500 S/N 015XX which is not 
remembering the antenna configurations I enter.   K4D - KPA500 - KAT500.  
KAT500 gets its power from the K4D auxiliary DC port.   

KAT500 is running latest firmware version 02.05.   Mac Utility is version 
1.21.10.9.   I have reinstalled firmware.  No change.   I have reset to factory 
configuration, then reloaded configuration, no change.   

Some “for examples”: 

1. Each time I open the KAT500 utility, the Maximum power (watts) on the Edit 
Configuration tab reverts to “1” watt.   I previously selected “Optimize for 
KAT500.” 

2. I will assign 20 m to both ANT 2 and ANT 3, for example, but this 
configuration reverts to no “Enabled” antennas and Preferred is “Ant 2.” 

On the other hand, the KAT500 appears to have correctly memorized the tuning 
settings.   I operate with KAT500 in “MAN” and have previously gone through the 
bands memorizing tuning settings. 

The specific problem I have is that, for 6 meters, I want to use ANT 2 but the 
KAT500 is not letting me change from ANT 3.   

And while I am not using ANT 1, I’m not able to configure a band/antenna 
combination such that I can only switch between ANT 2 and ANT 3. 

Thanks in advance,

Re: [Elecraft] KAT500 - can't change antennas on 6 meters

[Dennis Moore]

I'd still suspect the config settings, this test just showed that the 
KAT-500 is doing well mechanically. The tuner is getting a signal from 
the K3 telling it what band you're on so appears to be limiting your 
options based on that band. You can repeat the mode/ant test with the 
radio off, you should get the same results as with the control cables 
disconnected.


In the utility, Edit Configuration, Antenna tab, go through each of the 
band settings and enable whatever antennas should be available on that 
band. If you've already done that and it still isn't working right, I 
don't know where to go next.

Thanks for the suggestion.  Good test.

It turns out that Yes, I can change antennas now on 50 MHz when I disconnect 
control cables.   H.

I reconnect the control cables, and the symptom of not being able to change to 
antennas other than antenna 3 on 50 MHz, returns.

So one conclusion: maybe not the KAT500 settings.

Re: [Elecraft] KAT500 - can't change antennas on 6 meters

[Ted Edwards W3TB]

I had something similar on my KAT-500 where I could not get to antenna
connection 3.

What I did was to do the update of the software and then open it to
manually turn on antenna 3 and it was fine.

I have the cable if you need to do that.

Re: [Elecraft] KAT500 frequency memories question

[john]

As Don said it is not difficult to sort by subject. I also prefer a single
list and often find it educational and enjoyable to read about Elecraft
products that I do not own. Towertalk does not have separate lists for
verticals, Beverages, Yagis, rotators, towers, grounding, etc. One list is
easy to follow, especially if posts are on topic. Last month there were
about 200 posts on this list so it is not that difficult to even manually
pick the ones of interest.

There is a lot of overlap between the various devices, so it is good to list 
each involved.

It is quite understandable for users to have set up external email lists for 
the devices, but don’t expect us to know about them, which explains my surprise 
(and delight) when I discovered the iogroups KPA500 list.
Learning things from other users is always good and mostly enjoyable!

It is, here.  The device being commented on, should be part of the 
header when a thread is started so folks can read it or skip it.


But it's MUCH nicer to have separate groups for each item.  One may not 
have a KX2, KAT500 or other Elecraft device and the often numerous and 
ponderously long threads can add up to a LOT of email to be deleted.


Being a member of the specific device lists, limits that and the email 
noise floor.  Being on a targeted list improves the chances of getting 
an accurate answer or solution.


Having a varied interest in many things, I get a low of 50 emails a day, 
sometimes peaking near 300 per day or more.  By limiting to the specific 
groups of interest I find I can manage it better and when it gets too 
noisy on a topic, I can drop out of that thread (if the list is on 
groups.io, most of mine are).  Thankfully the lists don't 'blow up' 
often so the daily average is under 100 most times.


Almost ALL of them are quickly deleted, less than 5% are answered and 
under 1% get saved for future reference (that's what archive diving is 
all about).

Re: [Elecraft] KAT500 drops out during voice peaks

[Lyn Norstad]

I had a similar problem a couple years ago.  It turned out to be a lightning 
arrestor device on the 600 ohm OWL that was arcing over.  I replaced it with a 
higher capacity unit, and the problem disappeared.

No, it’s always been on manual since I got it. And it never used to do this. 
Nothing is changed in the shack except in using a 4:1 balun instead of a 1:1. 
The timing is similar.
Tomorrow I’ll reinstall that and see if it persists.
An arc outside is a thought too. I will check my open wire feed line as well.

Re: [Elecraft] KAT500 drops out during voice peaks

[Jack Brindle via Elecraft]

It sounds like you may have the KAT500 set for AUTO. Change it to MAN and it 
should perform much better.

The rapid signal changes associated with SSB operation can cause issues with 
the sampling of the power in the directional coupler,
causing readings that make the KAT think it needs to do a tune. By using MAN 
mode you get to decide when a tune is needed,
making everyone much happier.

Something arcing over on voice peaks would do what you describe.   Are
there any weak insulators or spots where something might arc?

Re: [Elecraft] KAT500 drops out during voice peaks

It might help if we knew more about the antenna system; what antenna, 
balun, power rating of them vs. power running, RF feed back in shack, 
any other info might help us point at what to look at...


I used to have some similar events, and got rid of them with a 
combination of toroids and current chokes in feed line; was suffering 
too much RF in shack, and this fixed it for me.

Re: [Elecraft] KAT500 Attenuator

[Wes]

I think the only thing that is for sure is that this is very poorly documented.  
The schematic shows two resistors, the assembly manual shows one, and the 
correct value of the one (by my measurement) is unknown.  Whether or not it is, 
or isn't, used is another unknown.  It seems to me that Elecraft could comment 
on this and clear this up, but that hasn't been forthcoming.  Silence isn't 
always golden.

Thank you for your response.

Looks like I can down load 1.21.10.9, after download and Extraction I have the

I do have access to the KAT, so will leave it at that for now, too much time

If I remember correctly, there is also an updated version of the KAT500

Re: [Elecraft] Kat500 Firmware

The KAT500 Utility software is v1.21.9.15.  Use it to download and install the

Have you tried under Windows?

It's always worked perfectly for me.

Hi,
Having difficulty loading latest version of the Kat500 utility.  The

the new version does not load but the message “ Input hex file is corrupt,

I have the same issue attempting to load a Mac and Linux.

Perhaps 2.05 is not available?  Or is there a fix I am not aware of, or perhaps

Re: [Elecraft] KAT500 Attenuator

[Andy Durbin]

" Have we, in fact, established that this attenuator is enabled at any point of 
the tune cycle? Because if not, then we're all spun up for nothing."

KAT500 Serial Command Reference Revised 8/18/2021 firmware version 02.00 says:

"ATTN Enable Attenuator GET format: ATTN; SET/RESPONSE format: ATTN0; 
(disabled) or ATTN1; (enabled). Selects relay K22, which switches in an 
attenuator resistor. It may take a few milliseconds after issuing an ATTNx; 
setter before the relay changes. Firmware releases the attenuator if it detects 
power high enough to damage to the attenuator. Firmware normally inserts the 
attenuator during “full search tune” to present a more consistent load to a 
transceiver during tune operations. The attenuator is disabled if the tune 
power is too low with the attenuator in place."

This version was released so the document was compatible with firmware 2.05 
changes.

As I have said earlier in this thread I see no evidence that ATTN changes state 
during a "full search tune".

We are left with an attenuator design change that no one seems to understand 
and documentation that may not be correct.  Whether that is "spun up for 
nothing" probably depends on one's perspective.

Andy, k3wyc

Re: [Elecraft] KAT500 Attenuator

[Andy Durbin]

"I took the cover off mine and verified that the shunt resistor was missing and 
the series one measured 228 ohm.  Clearly, if this is dynamically switched 
while seeking a match the poor exciter is going to be totally confused. "

The list and private replies I have seen seem to show the attenuator with both 
resistors presents a reasonable match to the exciter.  The attenuator with R7 
removed presents a horrible match to the exciter.

With the single resistor attenuator active my TS-590S load is so bad that it 
folds back to very lower power output, far too low for the tuner to continue 
the tune cycle, so it would then switch out the attenuator.  However, I don't 
see any sign that the attenuator is ever switched in circuit on my KAT500.  I 
have only recently added ATTN to my monitoring and recording so I have no data 
from firmware 1.75 or earlier.  If I get bored I may load 1.75 to see if I can 
detect attenuator activation.

Re: [Elecraft] KAT500 Attenuator

[Wes]

I took the cover off mine and verified that the shunt resistor was missing and 
the series one measured 228 ohm.  Clearly, if this is dynamically switched while 
seeking a match the poor exciter is going to be totally confused.  The 
attenuator should have been implemented with two 30 ohm resistors in the first 
place.  What motivated them to remove one is a mystery.


The fact that mine appears to have changed value says to me, that while clever, 
the use of the bottom panel for a heat sink is problematic.  I suspect this is 
also the case in the K3/K3S LPA where there are a lot of FET failures.

Just went through different antenna configurations and bands. Using the KAT500

SWR/PWR meter in the line between the radio and KAT500 shows the same values.


In receive mode, I hear a relay click when selecting the ATTENUATOR and again 
when de-selecting the ATTENUATOR.  Also noted the RX signal drop about ~3 dB 
{maybe less} when the ATTENUATOR is selected.


I did notice initially when selecting the ATTENUATOR it seemed to be 
inconsistent in results for a few times.  I figure this is some issue with 
relay contacts.   Once exercised 3 or 4 times,  no further strange operation 
was observed.


Don't have a clue if the resistors in question are installed or not.

I recall that certain ICOM tuners insert an attenuator on the input when 
running the tune routine.  This is said to provide a constant impedance/load 
to the transmitter while the tuner runs through its range of L and C values.   
This of course is for a radio that folds back power when the SWR is >3:1 or so.

Subject: [Elecraft] KAT500 Attenuator
Message-ID:
 



Content-Type: text/plain; charset="iso-8859-1"

KAT500 has an input attenuator that may, under certain conditions, be 
activated during a full search tune.   Page 1 rev C of the KAT500 schematic 
shows the attenuator is a divider consisting of R6 and R7 which are both 39 
ohm.  My KAT500 serial number 2609 does not have R7 fitted and R7 is shown as 
not populated in Figure 17 of KAT500 User's Manual Rev C6.


The removal of R7 changes the potential divider into a simple series resistor 
and my measurements show my KAT500 presents a very poor match to my TS-590 
exciter when the attenuator is active.  In this example the KAT500 was in 
bypass and connected to a nominal 50 ohm dummy load.  The impedance presented 
to my TS-590 by KAT500 was measured with an LP-100A:


Att Out:  R 48.1, X 2.4, Pwr 4.48, SWR 1.06
Att In:  R 22.3, X 162.6, Pwr 0.55,  SWR 9.98

Do other KAT500 owners see similar results? (Attenuator can be switched 
in/out with KAT500 utility)


Can someone please explain why the attenuator was changed.

Thanks and 73,
Andy k3wyc

Re: [Elecraft] KAT500 Attenuator

[Wes]

Guys,

I'm not about to remove all of the cables to look but using my iPhone camera it 
looks like I have S/N 1418, which I kit-built.


My R7 is AWOL and R6 measures about 228 Ohm.

Looks like Elecraft needs to explain.

there must be a later version that documents the elimination of R7.

Re: [Elecraft] KAT500 Attenuator

[Lyn Norstad]

Andy -

My KAT500 (s/n 2916) behaves pretty much the same way.  I don't know if R7
is present, but tuning into my normal antenna produces these results:

Man/Auto (doesn't matter): Att Out = SWR 1.00
 ""   "   " Att IN = SWR 99.99

My guess is that the KAT500 cannot get a strong enough signal to tune
properly with the Attenuator IN.  Interestingly, when it was new, it did not
have that problem.  Perhaps R7 has failed.

73
Lyn, W0LEN

PS - Where did you find KAT500 rev C schematics?
Thx.

Hi Andy,
No, not with the beta, that is untested at this point.  I need to move

Re: [Elecraft] KAT500 beta 2.04

[Dave]

Given we are talking about Beta software, I think I have located another 
issue with the KAT500...


If I use any sort of fast turn around transmit/receive cycle software, 
like VARA, under Winlink, or ARQ type software modem, the tuner tries to 
re-tune every time a most transmit cycles, even with a good SWR on the 
antenna.


My antenna has 1.5:1, and if in bypass all works fine.  If in MAN, the 
tuner goes into a tune cycle...  Which faults the KPA500.  Any suggestions?


I do not have a computer connected to the KAT500, but could connect one 
if needed.

Here is a more complete list:

* An enabled antenna is not selectable with mode BYP

* F; interrogation returns zero after CAT induced band change

* Unexpected behavior for FCCS and FCMD

* Fault code 01 when attempting to tune with low power

* Fault 2 leaves KAT500 in bypass when fault cleared

* Disabling "Tune on QSY" option does not prevent RF count re-tune if CAT 
frequency is available to KAT500.

All the above are fixed in beta 2.04.

There are also changes in full tune implementation that make is less likely 
that TX power foldback will result in early termination with a poor match.

FCCS, FCMD, MTM and MTA commands which did not work as documented have been 
replaced by FDT.  (See command reference for details)

For anyone using CAT control, the biggest change is that the CAT provided TX 
frequency takes priority over the counter frequency and counter will no longer 
cause a re-tune at start of, or during, TX.

(All the above are based on my notes and the Elecraft release notes should be 
taken as the official version of the changes.)

Could you note some of the ‘fixes’ that are not noted in the release notes?

Second, this firmware is marked ‘Beta’.  I typically don’t install stuff until 
it is the production version.  So are the changes/enhancements significant 
enough and the Beta is tested well enough such that I should go ahead and 
install the firmware the next time I’m at the ham station in November (I 
operate remotely)?  The currently installed firmware is 01.75.  

Third, am I correct that the I can use an earlier version of the KAT500 utility 
to install the new firmware and that older utility software will ‘play nice’ 
with the new firmware?  The currently installed KAT500 Utility is v1.16.7.25 
that has a 2016 copyright date.  

Thanks,

"Tried the new version of the Utility.   'Invalid handle' error when 'Copy New 
Files from Elecraft' is clicked.  Unzipped the new beta firmware into my beta 
directory, and when I tried loading the beta firmware I got 'Cannot start a 
busy state machine' error."

All my testing was done with alpha loads sent to me by email.  I copied them to 
a local directory, pointed the KAT utility to that directory, and then loaded.  
Never saw the issue you report.

Utility is a standalone exe.  If you don't like the new one simply run the 
earlier version.  I don't remember what the last officially released version 
was but I have several versions filed away.

Hi Andy,

Tried the new version of the Utility.   'Invalid handle' error when 'Copy

Unzipped the new beta firmware into my beta directory, and when I tried
loading the beta firmware I got 'Cannot start a busy state machine' error.

I'll stick with v 01.75 for now ...

Re: [Elecraft] KAT500 - does it earth antenna connections

[Andy Durbin]

"You don't need to manually choose an antenna on startup. It remembers what
was last used on each band (assuming you are using an Elecraft or Kenwood
rig with it). I think it will still remember the last used even in a dumb
situation without knowledge from the radio; it just needs the radio support
to have "per-band" memory."

No radio support is needed for antenna per-band memory.  All the KAT500 needs 
to know is the TX frequency.  It then decides which antenna to select based on 
"band" and the antenna preferences defined by the KAT500 PC Utility.

A weakness of this design is that, if only RF sensing is used for frequency 
determination, the KAT500 may fault due to a mismatched load before the 
appropriate antenna has been selected for the new band.

Antenna selection can be performed by serial command but, even though my 
controller is capable of that, I have seen no reason to replicate the antenna 
selection logic already built into the KAT500.   There is a caveat though -  
the internal antenna selection logic doesn't work correctly when KAT500 is in 
BYP mode.  (The workaround for that defect is to never use BYP mode.  MAN mode 
with Byp active is electrically the same and antenna selection does work 
correctly in that configuration).

Andy, k3wyc

So if I have one antenna port which no longer seems to function (port 2) the

Re: [Elecraft] KAT500 - does it earth antenna connections

[Jack Brindle via Elecraft]

This is not quite correct. It does not connect unused antenna ports to ground. 
It does have a GDT and 1 meg resistor to ground on each port, however.
When power is off to the KAT500, ANT1 is connected directly to the input port.

But you are correct in that it has three output antenna ports.

You don't need to manually choose an antenna on startup. It remembers what
was last used on each band (assuming you are using an Elecraft or Kenwood
rig with it). I think it will still remember the last used even in a dumb
situation without knowledge from the radio; it just needs the radio support
to have "per-band" memory. I could be wrong. I know it remembers fine with
my K3.

Re: [Elecraft] KAT500 - does it earth antenna connections

[Ted Edwards W3TB]

Interesting idea.
I have two antennas, so I could connect my ground to #1 and antennas to #2
and #3?
Just manually choose an antenna on start-up.   Hm-m-m-m-m.

It has 3 antenna connections, not 4. It grounds the unused ones and selects
antenna 1 on power-off. I put my dummy-load on antenna 1 so my station is
disconnected from the antennas when powered down.

Re: [Elecraft] KAT500/KPA500 with IC-7610?

[Ken Winterling]

I have had the IC-7610 and the KPA500/KAT500 for over three years and it
works very well when I switch bands with the intention of transmitting. My
"nit" to pick is that the KAT500, as has been said, can not be preset by
the IC-7610 in receive. It can preset the KPA500, for all bands but WARC,
by using a DIY "band data" voltage cable (Icom doesn't support band data
voltages for the WARC bands).

If I want to *listen* to different frequencies on the IC-7610 that are on
different antennas connected to the KAT500 I have to manually select the
antenna on the KAT500. This makes scanning frequencies on the IC-7610
impossible.

The KPA1500, that combines an amp and antenna matcher (aka tuner), can read
Icom CI-V data and preset both the amp and the "tuner". This feature should
have been/should be available for the KPA500 and KAT500. I believe the
KPA500 and KAT500 can read data from Kenwood and Yaesu transceivers. Why
was Icom left out of the mix?

Re: [Elecraft] KAT500/KPA500 with IC-7610?

[Lyn Norstad]

Yes, I believe you're right, Andy.  At least the CI-V is capable of
including frequency data - but KAT doesn't read it.

The KPA does read band data, presumably from voltage.

KPA500 only needs to know the band but KAT500 needs to know the actual
frequency within the band.  Isn't ICOM band voltage exactly that - a band
indicator not a frequency indicator?

To implement the interface properly you'd have to know the exact TX
frequency which I think could be extracted from CI-V data.

"Both are VERY quick to sense TX frequency. All it takes ia a dit or a tap on

May work for you but are you using KAT500 antenna port selection?  My issues 
with RF detection as the primary tuning mechanism include the fact that the 
KAT500 will fault before it has time to select the correct antenna for the band 
in use.

I need the KAT500 and KPA500 to be configured before I transmit.  I suspect 
that anyone who uses KAT500 antenna port selection would too.

Re: [Elecraft] KAT500/KPA500 with IC-7610?

[Lyn Norstad]

I'll chime in too, echoing what Ken says.  All you need is the "tune" cable
to connect the KAT500 to the rig for control of the Tune function.  I also
use the LDG cable (just because it's easy ...) but you can easily make your
own.  (I am not familiar with the Ten-a-Tuner mentioned by Buck ... perhaps
it is the same?)

I prefer to use the Elecraft Utilities for both KPA and KAT500 for all
tuning and setup settings, but the Tune button on the rig (or tuner) works
fine as well (it automatically supplies the proper power for tuning).  

Generally, for digital operation I set the rig to about 18% power.  For SSB,
up to 25%.  All the rig settings are automatically stored with each saved
config file.

The only downside to using Icom gear with the KPA/KAT500 is that Elecraft
does not "read" the frequency "voltage" indicator and therefore does not
preset the tuner to the correct values without transmitting.  That
ultimately is not a big deal, but does produce a 2 or 3 second delay for
tuning when first transmitting after a band or significant frequency change.
I generally hit the utility's Tune button as soon as I change so the
receiver sees a good match.

Chuck,

I, too, have been using an IC-7610 with the KAT500/KPA500 combination for
several years. My IC-7610 TUNER jack is connected to the TUNE jack on the
rear of the KAT500 via a LDG Electronics IC-PAC-6 cable. While the TUNE
button on the IC-7610 or the TUNE button on the KAT500 activates the
IC-7610 10W tune function and causes the KAT500 to tune, the Elecraft
KAT500 manual stated "If a tune cycle is performed, 20 watts or more will
produce more accurate tuning".

My procedure is to switch to RTTY mode on the IC-7610 and key the rig. The
KAT500 matches the load and I return the rig to the previous mode. This
literally takes only a few seconds. Yes, the TUNE button works but I have
found that sometimes my method produces a better match. Be sure to follow
the KAT500 "training" procedure to store your various bands and frequencies
in the tuner so they can be quickly recalled.

As has been mentioned, you have to manually adjust your output as you
switch between the amp and full power. I have a Brother P-Touch label on
the amp to remind me about max power input.

As for obtaining a tuner cable, you can get one from LDG, and other
vendors. The IC-PAC-6 cable is 6' long while the IC-PAC cable is 14" long.

Amphenol has been a leader in quality connectors for RF.   Cannon and 
Neutric are good for audio brands.  There's others but be aware there

are going to trust its operation to a $1 connector?  That is false economy.


Also, when soldering the center pin on a PL-259, do NOT let solder build 
up on the outside of the male pin.  It will expand the center contact 
when inserted into the SO-239 and problems will abound.

Re: [Elecraft] KAT500 ANT1 problem

[Dave]

I am using the Times Microwave connectors on Times Microwave LMR-400 for my HF 
antennas. Except a Belsen 8267 jumper around the rotor to Yagi. The Times 
Mocrowave connectors for RG8, 214, 214, 9913, and LMR400. I had the LMR400 left 
over from a job so no cost except the UJF male and one UHF female connectors. 
The PolyPhasers are type N female. As long as the coax is not swinging in the 
wind or run around a rotor then the LMR400 is fine. 

Hardline for my cable runs on HF would be overkill as far as loss since runs 
are under 100 feet for each of three antennas. 

Amphenol is the “gold standard” for RG8/213 installations.

No question about that, but my comments were with respect to coax other

Re: [Elecraft] KAT500 ANT1 problem

[David Christ]

5/32” inches is 0.156” which is 3.968 mm.  So if the Asian manufacturer 
considers 4 mm easier and close enough the pin will be oversize.WW II 
drawings give the pin diameter as max/min 0.158/0.154 .  5/32 is right in the 
middle of this range.  I don’t have the MILSPEC documentation but guess this is 
likely the dimension. Whether that is enough to create problems, I don’t know.

But I also saw a drawing where the pin diameter was specified as large as 4.01 
mm.

Buying only from manufacturers with a known track record of QA and following 
MIL Specs seems to be wise.

connectors -- Switchcraft and Neutrik. Both report having had problems
