I have a Fluke DVM also. I gulped when I bought it some 30+ years ago, but it 
was a good decision. It’s like a Snap-On wrench. It just feels right and never

 That's for "bonding".  Where do you pick up "ground" - at the radio, at

Long time no hear, Dave!

I got my interest in SWL radio and onto ham radio from a project in Boys
Life in the late 1940s.  It also helped that one of my father's buddies
was a radio repair tech during WW-II but Harry was not a ham himself.

Re: [Elecraft] K3 - Power cable voltage drop

2019-12-24 Thread Bob McGraw K4TAX

Yes true.   However seeing they way some hams configure their stations, 
building or modifying and implementing a power supply with voltage 
sensing, is of serious questionable nature. Likewise, in conditions 
where power supplies are buried under the desk.  One needs to see the 
volt meter when the supply is first turned on to assure the voltage is 
correct.   And that should be done before the radio is turned on.     Oh 
I know about crowbar circuits, but if that $2.50 part fails it will 
likely take out a $3000 radio.   This just isn't smart.


Having worked with equipment that was supplied with 35 ft or 50 ft power 
cables for loads of 20A to 30A at + & - 18 volts, I understand just a 
wee bit about voltage sensing circuits and what makes them oscillate.


Just err on the safe side.    And for ham radio, it likely is not 
necessary to have or implement remote voltage sensing.  Wire and 
connectors are cheap.   Use a shorter length of wire or larger gauge 
wire.   There's no likely component failure with this approach.

[Elecraft] KAT500 - Tune on QSY

2019-12-24 Thread Andy Durbin

Sorry for the inadvertent premature posting.  I'll try again - 

After I had posted my observations on the behavior of KAT500 "Tune on QSY" 
option  I suggested to an owner of a TS-890S, KAT500, and KPA500 that he should 
try disabling the QSY option as it might cure his annoying re-tunes during 
transmit.  It did not fix the problem.

After exchanging email with him I have been able to reproduce the problem and I 
think I understand it.

Disabling the "Tune on QSY" options, as previously reported, prevents RF count 
re-tune but still allows CAT frequency re-tune.  It works fine if either one, 
or the other, is enabled but not when both RF count and CAT can change the 
KAT500 frequency.

With "Tune on QSY" not selected, and FCCS and FCMD at default values, the 
KAT500 may re-tune during TX.  I have captured several events with my data 
logger and the sequence is the same each time.

What happens is that, when TX starts, the KAT500 is using the most recent CAT 
frequency.  If RF count frequency becomes different from CAT frequency then the 
"last observed frequency" is updated to RF count frequency.  Even if this 
frequency is in a different "bin" than CAT frequency there is no change in 
tuning solution as that is inhibited by "Tune on QSY" being inactive. All ok so 
far.

Now KAT500 sees the next CAT frequency update and, if it crosses a bin boundary 
from the RF count frequency,  there may be a re-tune.  Note that CAT frequency 
re-tune is not inhibited by clearing the "Tune on QSY" options.

The problem is most likely to be seen when the transmit frequency lies at the 
edge of a bin.  My tests used the FT8 nominal frequency of 1840 and 1840/1841 
is the boundary between bins 183 and 184.  A re-tune was seen at the start and 
end of every transmission when my TX freq was 1841. These re-tunes moved from 
bin 184 before TX, to bin 183 at start of TX, and then back to bin 184 at end 
of TX.

The paradox is that the transition to bin 183 tuning solution is triggered by a 
change of frequency from bin 183 to bin 184.

Bottom line is that disabling "Tune on QSY" option does not prevent RF count 
re-tune if CAT frequency is available to KAT500.

Detailed logger data available on request.

Re: [Elecraft] Reaching Across the Chronological Divide

2019-12-24 Thread Gwen Patton

On the subject of emergency support...

My local club did a documentary a bunch of years ago about how the club
turned to and helped with a local flood. It was in the archives when I was
Archivist, so we got it converted into a video file and posted it on
YouTube (with the club's permission). Since then, it has gotten a lot of
views, and is one of the ways we help promote ham radio in our area. The
beginning is a more modern introduction to the documentary:
https://youtu.be/xYx8VNzYwRE

But I also like to call attention to Clinton B. DeSoto's book "Calling CQ",
a bunch of great stories about how ham radio helped during disasters and
other emergencies. I helped curate it, with the permission of his estate.
You can read it at the Internet Archive, here:
https://archive.org/details/CallingCq-AdventureOfShort-waveRadioOperators

Then there's the 1939 "Pete Smith Specialty" short film by MGM called
"Radio Hams". It's very similar to the stories in Calling CQ, and I think
some of the segments were based on them. It's a little hokey, but the
subject matter is good. https://youtu.be/1BPcpQMbUPE

Re: [Elecraft] K3 - Power cable voltage drop

2019-12-24 Thread Bob McGraw K4TAX

With the Astron supplies, the 723 regulator does have provision for 
remote sensing.  And with a bit of work and some extra wiring and 
components one can have remote sensing.


I would suggest NOT doing so as remote sensing become "inputs" to the 
723 regulator chip and any noise or RF on the remote sensing lines can 
be very problematic.   Proper filtering and time constants will be 
required to prevent oscillations.


My suggestion is to use good quality #10 AWG wire, such as auto primary 
wire fitted with correct terminals on the ends.  Be sure to correctly 
crimp and solder as needed.   Suggested length is something less than 10 
ft.    Also be sure to have a dedicated ground between the ground screw 
on the back of the radio to the ground on the power supply.


In the end, if you desire to have remote sensing, purchase a suitable 
supply that provides remote sensing.   Life will be much easier.

[Elecraft] K2 Alignment & Test Part II

2019-12-24 Thread Neil Zampella


Hi,

Started to do the Align/Test Pt II, and properly saw the correct
frequency of 12090 +/- 30 kHz.   Tried the next part to adjust the
Reference Oscillator using my other K2 as the receiver and was able to
hear the oscillator at 3999, but C22 would not adjust to a
zero-beat. OK ... so it was close for the time being, so I figured
I'd use my KX3 to verify it later.  Moved on to the range test.   The
Band- and Band+ buttons did not affect the display.

Dug into the list archives, and saw a number of messages from Don to
check the solder joints, alignment, and type of D16, D17, R19, and
L31.    I realized that somehow I missed installing R19.   So I
installed the resistor, then restarted the alignment.   This time when I
switched to CAL FCTR, the rig did not display the expected frequency of
12090, but  a frequency of 3560 or so, flickering between readings.  
However, when I pressed the Band- button, it changed to a steady 12084,
but when the Band+ was pressed, back to the 3560 flickering.

I checked the other areas as referenced by Don such as the thermistor,
but did not see any issues such as solder bridges, etc.   I really do
not want to remove the thermistor board to check closer, but will if
there are no resistance or voltage readings I could use to verify that
its OK. I did verify the voltage readings as referenced by Don in
another message and they were within expected.

That said, I am rather limited in test equipment, with just a good
digital multimeter, so I can't put things on a scope, etc.    Any hints
would be appreciated, I can say I'm very sure I did not put any of the
ICs in backwards, I learned that the hard way when building my K2/100.

Merry Christmas to all, and a Happy New Year.

Neil, KN3ILZ

Re: [Elecraft] KAT500 - Tune on QSY

2019-12-24 Thread Andy Durbin

 December 17, 2019 I posted the following"

"I've had my KAT500 for about 18 months and I thought I had come to know it 
quite well.  Today I found something that surprised me.

The KAT500 utility has 2 "Memory Recall on Tune" options, one for MAN mode and 
one for Auto mode.  My understanding was that, if these options were not 
enabled, the KAT500 would not use RF frequency count or CAT TX frequency to 
change the tuning solution if the frequency was changed within band.

For MAN mode, with memory recall tune not checked, it appears that the KAT500 
does still select tuning solutions as appropriate for the frequency received 
over CAT.  It does not change solutions if CAT frequency is not available and 
RF frequency is changed.

The utility "Tune on QSY" page says:

"Enable or disable memory recall tune on transmit frequency changes with the 
check boxes below."

However, the help file says:

"The tuner continuously monitors the transmit frequency. Beginning with 
firmware version 1.20, the tuner performs quick "memory recall" tunes as the 
transmit frequency changes within the current band, recalling the memory 
closest to the current transmit frequency.


If you prefer that the tuner not attempt to change settings for "in-band QSY" 
based on the transmit frequency count, uncheck the "Memory Recall Tune on QSY 
in Mode MAN" checkbox."


So it seems to be doing exactly what it says in the help file and there is no 
option to inhibit tuning changes if a new frequency is received over CAT.


I'm not suggesting any of this is a problem but it did surprise me."



After posting that I suggested to an owner of a TS890S, KAT500, and KPA500 that 
he should try disabling the QSY option as it might cure his annoying re-tunes 
during transmit.  It did not fix the problem.


After exchanging email with him I have been able to reproduce the problem and I 
think I understand it.


Disabling the "Tune on QSY" options, as previosly reported, prevents RF count 
re-tune but still allows CAT frequency re-tune.  It works fine if eirther one, 
or the other, is enabled but not when RF count and CAT can change the KAT500 
frequency.


With Tune on QSY disabled and FCCS and FCMD at default values the KAT500 may 
retune during TX.  I have captured several events with my data logger and the 
sequence is the same each time.


What happens is that, when TX starts, the KAT500 is using the most recent CAT 
frequency.  If RF count frequency becomes different from CAT frequency then the 
"last observed frequency" is updated to RF count frequency.  Even if this 
frequency is in a different "bin" than CAT frequency there is no change in 
tuning solution as that is inhibited by "Tune on QSY" being inactive. All ok so 
far.


Now KAT500 sees the next CAT frequency update and, if it crosses a bin boundary 
from the RF count frequency, then there may be a retune.  Note that CAT 
frequency retune is not inhibited by clearing the "Tine on QSY" options.


The problem is most likely to be seen when the transmit frequency lies at the 
edge of a bin.  My tests used the FT8 nominal frequency of 1840 and 1840/1841 
is the boundary between bins 183 and 184.


For the most recent test I modified my controller to be a verbose output of all 
KAT500 interrogation responses.  Normally it only reports changed values.  he 
is the event sequence for an FT8 TX with a TX freq of 1.841:


2019-12-24 15:23:00 F 1841; << F before TX is 1841

Re: [Elecraft] Reaching Across the Chronological Divide

2019-12-24 Thread Edward R Cole


Sub-Topic: survival in emergencies.

I had a good "taste"of that a few years ago when the road from 
Anchorage to the Kenai Peninsula (pop 60K) (where I live) was blocked 
by avalanches for three weeks.  All store products come by truck down 
that 180-mile road (there is only one road).  Power ties were cut but 
we have local generation  plants plus a hydro-plant, so outage was 
short.  My biggest emergency was feeding my twelve sled dogs; stores 
ran out animal feed real quick.


I use to live in a small town which lost power and phones during the 
avalanche.  Convenience store's freezers thawed out and town had a 
serious supply problem.  National Guard flew in a standby generator 
for them after two weeks.  Town had one gas station so ran out.  One 
ham lived there to get the word out.


Having lived ten years off the grid in that town, I had good training 
on surviving.  I had no electric, telephone, or water. Fifteen 
gallons of chainsaw fuel was my annual heating bill.  Lights and 
stove by Coleman were propane (bout three months per 
bottle).  Freezer was a military container out in a snow bank.


So about eight years ago we bought a 6500w Honda generator to power 
the house.  We have natural gas appliances and a well so only need 
electricity to be independent.  I keep 20 gallons of fuel for the 
generator which will carry us about five days.  Only have one house 
dog so that is easier.

Re: [Elecraft] K3 - Power cable voltage drop

2019-12-24 Thread Don Wilhelm

That would be a neat thing to do, but DO NOT do that on a power supply 
that is connected to anything other than the rig you are sensing from.


The voltage on other devices connected to the power supply will increase 
when you transmit on the rig to which the sense wires are connected.


Use a separate power supply for accessories.

If you need to use the same supply, you can adjust the voltage upward - 
the SS30 sold by Elecraft already has an output voltage of 14.1 volts.
Still use a separate power cable to the transceiver and another cable to 
any distribution box that you use for accessories for best results 
(lowest voltage drop when transmitting).

Re: [Elecraft] K3 - Power cable voltage drop

2019-12-24 Thread Jim Rhodes

I have thought about doing that. Just requires a 2 wire hookup with small
gauge wire. But I run all of my small items like the remoterig box, LP-pan
box, VHF/UHF rig and so forth off of the main supply and if I have a larger
than anticipated voltage drop on rig power cable the voltage on the other
tings could go fairly high. The power supply is a HB thing with at least a
50 amp capacity and plenty of voltage overhead before pass transistors.
(Used to run 2 HF rigs before downsizing.)

[Elecraft] K3 - Power cable voltage drop

2019-12-24 Thread Karin Johnson

Why hasn't anyone used remote sensing at the radio voltage input?
As far as I know all of the Astron supplies don't have external sense
wiring.  Many so called professional grade high current supplies provide
For external connection of the voltage sense back to the regulator chip.
I've toyed with this idea a bit but haven't had the time dig in to the
Astron supply I have.  If this were implemented then one could maintain
13.8 volts or whatever you desired at the radio power supply inputs,
Regardless of the current draw.

I know that others have responded to your query, but allow me to make some 
additional points.

1.  I presume that you purchased the remoterig from Elecraft and that you have 
the RemoteRig cables from Elecraft to connect the remoterig not only to the 
K3/0-mini but the remote rig to the K3.  These cables provide the critical 
interconnects needed for the K3/0-mini to function properly.  The K3/0-mini 
manual does a nice job of explaining how to make the proper connections.

2.  I use a y-adapter to connect the remoterig PTT cable to the PTT port of the 
K3 so that the PTT switch I use at the K3 will still function.  There is no 
problem having both PTTs connected at the same time.  This will allow the K3 go 
to into transmit by command of the remoterig or by the handswitch at the shack.

3.  I use a stereo y-adapter to connect the Remoterig Audio cable to the 
Speaker port of the K3 so that audio will be fed to both outputs.  This setup 
does cause my external speakers at the station to change volume when remote 
operating as it also provides audio to the Remoterig. In other words, the AF 
volume on the K3/0-mini will control both audio outputs.  Since I’m not at the 
station when operating remote and no one is around, having the speakers active 
doesn’t bother anyone.  If the K3 is located where audio might bother others, 
then either turn off the speakers (if they’re powered) or install a cutoff 
switch/unplug the speaker(s).  

4.  Keep in mind that the K3/0-mini controls what the K3 is doing as the 
K3/0-mini front panel is duplicating what the K3 is showing on its panel. That 
is, as you increase audio on the K3, it is also potentially increasing audio of 
speakers at the shack. If you set a parameter on the K3/0-mini, it is 
displaying what the K3 front panel is showing as that adjustment is made.  One 
area to note is how microphone management is done.  The Remoterig uses the rear 
mic connector of the K3.  Thus, on the K3/0-mini, you must use the K3 Menu to 
set the mic source to the rear connector.  If the mic connected to the 
K3/0-mini needs bias, you set that through the remoterig configuration.   In 
other words, mic selection through the K3 menu has nothing to do with the mic 
input of the K3/0-mini itself; rather it determines the mic input used by the 
K3 itself.  Both the 8-pin connector on the front panel of the K3/0-mini and 
the side Mic connector are active.  Thus, mic selection using the K3/0-mini 
does determine whether the mic input is from the Remoterig (rear mic) or from 
the K3 itself (front mic).  

5. Management of the KAT500 and KPA500 can be done several different ways.  
Clearly, basic operation of both units will work the same as before if the 
appropriate cable connections are installed as described in the Elecraft 
manuals.  One can use a remote connection to a PC in the shack and use the 
Elecraft utilities.  I prefer to manage the KPA500 with the Remoterig RC-1216H 
which provides a web-based display of the KPA500 front panel and is connected 
to the amplifier through a RS-232 connection.  This allows me to manage the 
amplifier with any PC, Mac, iOS device, etc.   I have port forwarding set up at 
the station so that I can access the RC-1216H directly.  As the RS-232 
connection is attached to the RC-1216H, I cannot use the KPA500 utility from 
the shack computer. However, I don’t see that as a problem.  

The KAT500 can be managed using the PC in the shack and then remotely 
connecting to the shack computer to manage the KAT500 running on the shack 
computer.   I manage the KAT500 one of two ways.  I’ve installed a 
serial-to-ethernet converter (Lantronics) which allows me to directly connect 
to the KAT500 remotely and run the KAT500 utility on the PC where I am.  Or, I 
can have the PC in the shack connect to that same serial-to-ethernet converter 
and run the KAT500 software on that machine.  In this instance, I use VNC 
Connect to access the shack computer using any PC, Mac, iOS device, etc.  
Sidenote: If I didn’t have the RC-1216H, I’d probably be managing the KPA500 
the same way.  

6.  Lastly, please keep in mind that if you’re intending to remotely operate 
from a significant distance from the shack, it is imperative that you test

Walter,

Someone did comment (maybe a different thread/group) about reading 
Scouter and Boys Life at the barber shop and noted that ARRL has NO ads 
about radio in the mags.  He or someone else noted that SWL mags have no 
ARRL ads, either...


I think ARRL has "missed the boat"...

ARRL has flyers for DIY, but no "push" to the youth to go along with it.

Radio Merit Badge does at least provide a sample of ham radio...

A troop in our area uses radios to allow groups of older youth to hike in 
separate groups. The fast group (always the youth, oddly) checks in every 15 
minutes. If they can’t make contact, they stop until they can. With a license, 
they can switch from FRS/GMRS to amateur bands and hike with a bigger gap.

JOTA is on the third full weekend of October every year. This year, we had over 
9000 Scouts participate in the US.

https://k2bsa.net/jota-usa-reports/

 From running a JOTA station a couple of times, I believe that prospective hams 
have just as wide a range of interests as active hams. We need a shotgun 
approach with each pellet (metaphor falling apart here) being someone who is 
excited about that activity. You don’t have to be an expert—I ran the “send 
your name in Morse Code” station and I’m not a CW operator—but you do need to 
represent how that activity could be exciting.

Hands on, do everything hands on. No butts in seats for PowerPoint. Anybody 
ever say “I think I’ll go home and watch a nice PowerPoint preso tonight”?

Here are some photos from our JOTA station this year. I’m the guy with the

sheet in front of the KX-line. HF was pretty dead. Must do digital modes next

All 15 pin Y cables are not the same.  You need to have all 15 pins 
connected from end to end.  VGA cables will NOT work.

Re: [Elecraft] Reaching Across the Chronological Divide

2019-12-24 Thread Joseph Street

I believe this is a very important point.  The modern civilization, at least in 
the developed world has become so dependent on the infrastructure.  I'm pretty 
sure the younger generation has no appreciation for the extent of that and also 
how far reaching the impact of a breakdown of that infrastructure can be. Many 
of the not so young as well, I'm pretty sure. Back in '98 right after Christmas 
when a massive ice storm hit the north eastern US and Canada, my folks were 
without power for 14 days in January.  Many unforseen dominoes fell.  Large 
dairy farms had massive piles of dead cows they couldn't milk without 
electricity.  Didn't see that one coming.  They couldn't pump gas until the 
hand pumps came out and then they couldn't keep a ledger till the notebooks 
came out.  Grocery stores lost a lot of food and kitchens too.  No restaurants 
to turn to.   All of this was denial until days went by and people began to 
realize they had to do certain things old school until the powe
 r came back.  Hospitals have emergency generators but there were many small 
and not so small ways we fell on our faces.  The cell phones had some power but 
the towers ran out of backup power in short order and didn't get re-fueled too 
quickly given the breakdown of everything else. No internet. The field day 
setups came out and traffic was passed.  Of course there are many stories where 
amateur radio helped out but unless folks have some direct experience with this 
type of thing it is too easy to live in blissful ignorance of just how big the 
problem can be when critical infrastructure fails.  I don't like to dwell in 
doom and gloom but I do think that more can be done to impress the importance 
of alternative technology for communication on the general public and to help 
people realize how much their lives can change and to what degree when the 
infrastructure fails.  This can be an important point for keeping public 
perception of amateur radio as something current and import
 ant rather than just an antiquated relic of yesterday's generation.

One point that I don't believe has been addressed is Emergency
Communications. As a former ARES Emergency Coordinator, it seems to me
that if Emergency Communications could be presented to young people in
the right way it might interest some of them. It fills a need in the
community. When other communications break down, hams can usually find a
way to bridge the gap and provide the necessary communications. I can
remember some exercises in Spartanburg County, SC where most of the
people in the EOC were gathered around the ham radio position listening
to live, relevant communications that their positions weren't getting.
We were providing real-time communications because communications was
our only job. Many others had their primary job and communications was
something that they did when they had a spare minute.

Hi Mike. I sold my K0 setup a few months ago. It worked perfectly for years, 
but wanted to bring my K3 with me for the winter so I replaced it with a remote 
IC-7300. While up there for the summer I used to switch to remote mode when I 
went to the shore for the weekend, if I remember right there were three 
connections to  change. The PTT from foot switch to the remoterig box, the 
audio from local speaker to remoterig box, and the serial connection to local 
PC to the remoterig box. This took about a minute to switch over. I f I wanted 
to use the AMP and tuner I had to leave a local PC on running TeamViewer.

Hi all

So I have a K3/0 Mini with the remoterig setup. My station is a K3, P3, KAT500 
and KPA500.  I want to be able to keep it all hooked up while installing the 
remoterig system.  Is it possible to do this?  It looks like I need to 
disconnect the ACC CABLE going to the KPA500 along with the RS232 line so the 
remoterig can be used.  That pretty much disables the rest of the station. Am I 
missing something?   I sure don’t want to disconnect half of my station 
everytime I want to use remote.  I’d sure like any pointers on hooking this all 
up without disabling my station every time I want togo remote.  Any help is 
sure appreciated
