[Elecraft] K3 FT8 Levels Sanity Check

[LDE]

Line In Gain = 40 seems too high to me. I have from 80m. 20m Line IN Gain =
2 and at 15m = 20. ALC always shows 3. 4 bars. TRX = K3s with power 2 ... 4
watts for the PA SPE Expert. PA output line 400 ... 500 watts depending on
the band.

Re: [Elecraft] XG3 battery level indicator

[Robert G Strickland via Elecraft]

Jim...
Thanks for that. In my case, the output level that is selected starts a 
slow blink after in 5-15 seconds. I can't find anything in the manual 
that explains this.

[Elecraft] KX3 TX/RX antenna changeover relay?

[Ian Liston-Smith]

Many of us have separate receive antennas - often active loops etc. - because 
out transmit antenna picks up too much noise. Does Elecraft have a changeover 
device that switches between the two fast enough not to damage the rx antenna? 
Specifically for the KX3? Thanks.

PS: I have this option for the K2 and it's very useful.

73,

Ian, G4JQT

I have been studying the records (I have a background in space plasma physics). 
Of course, I am not an expert, but I do enjoy analyzing scientific data. It 
seems to me that cycle 25 is likely to be a very active cycle. I see that NASA 
is anticipating a peak with 115 sunspots in July 2025, but I suspect that it 
will be much larger. Oops. Guess we'll see.

[Elecraft] Sunspots and the K2, K1

[Louandzip via Elecraft]

I built my K2 and then a K1 during the solar maximum in 2001/2.  One of the 
hallmarks of the K2 is it strong signal rejection.  It was one of the best 
radios of the time and is still among the better radios today.  The K1 isn't 
really in the same league, but it's no slouch either.  The worst test I put it 
to was operating in CH on 40m during a contest weekend during a business trip.  
Huge wall to wall signals but I was able to participate fine.
Somebody mentioned switching in the K1's attenuator.  Originally, doing so 
created a loud audio pop.  I came up with a mod to eliminate this, adding a RFC 
across the contacts of the relay K1 (coincidentally) which was adopted as part 
of the design.  

I grinned when I saw Wayne N6KR's terse response.  He's still justifiable proud 
and protective of his babies.

Re: [Elecraft] Sunspots and the K2, K1

[Jim Sheldon]

I had just gotten my K2 after having problems with a close neighbor ham 
that ALWAYS ran his 2KW amp full bore, even for crosstown QSO's, had an 
early  Yaesu FT-1000 with super key clicks.  He refused to do the key 
click mod (so he could grab and hold a frequency in a contest without 
people encroaching on it).  He overloaded a Yaesu FT-897 which I 
replaced with an ICOM 706 MKII and overloaded that too.  I ordered & 
built a K2 which took care of the overload, if not the key click 
problem.  I loved that K2 and had a lot of nice successes with it.


First off, I was working 160 meters one early morning, heard a Caribbean 
station (will remain nameless to keep from shaming him) calling CQ (not 
CQ JA or CQ DX) so I called him.  He acknowledged but refused the 
contact because he said he was only working JA stations.  I continued to 
listen to him call CQ for a while when a JA station answered him.  After 
he returned the JA's call, the JA station said "Sorry, I'm only working 
USA stations this morning and then the JA called me!  - Wow.  I was only 
running the K2 at 5 watts on 160 and that was totally unexpected.  Had a 
nice chat with the JA station (got the QSL card to prove it about a 
month later).


Later, I inherited a tidy sum of money when my favorite Aunt passed away 
and got a full K line.  Final to the story, the FCC got on the local ham 
with the key clicks so he had to fix them, I now had a KPA500/KAT500 
behind the K3 and in a contest I could operate within a couple KHz of 
this guy with the K3's attenuator on and not have a problem 
copying/working weak signals.  Back when he was overloading the Yaesu & 
ICOM rigs I had, I asked him to turn the amp off in local QSO's but his 
comment was "Get a real radio!".  Well after I got the K line and ran 
the amp in contests, he asked ME to turn MY amp off.  My response to 
that was -- "Like YOU said, get a real radio!".  Shortly after that he 
moved out to a farm he inherited about 35 miles from me and I haven't 
heard him since - LOL.


Speaks extremely well for the Elecraft line's strong (even extreme) 
signal handling capability.  It was good, but not perfect with the K2 
but even better with the K3 and now a K3S.  At 78, I doubt I'll ever 
have a K4, but I fully expect the K3S to just keep on truckin' as it has 
for the last few years.


Thanks Elecraft for some of the best rigs of the age.

Jim Sheldon, W0EB

[Elecraft] KPA500 failure

[Wes]

I've been incorporating a new transceiver into my station and was going through 
setting the per band power limits for driving my KPA500.  When I got to 50 MHz, 
a band I seldom use, I was dismayed to note that there is no amplification, it 
operates as if in Standby.  The RF frequency sensing fails to switch bands and 
even manually switching to 50 MHz makes no difference.


I have the schematics, but it's unclear to me where to start. Any ideas welcome.

Never mind, I solved my own cockpit problem.  The transceiver has a different

Re: [Elecraft] Firmware development

[Rich NE1EE]

I ran my own small engineering company for 25 years. Projects ranged from $1ooK 
to $10M USD. We had no warranty claims at all. It takes a lot to produce 
software and hardware to that level of reliability.

Recently, someone posted on a different professional forum I am on "As a 
programmer I am faced with incompetence at every level. No one wants to put the 
time into making things great, just getting something out the door is the 
norm." I think that applies to a broad spectrum of products these days, and has 
applied for some time.

A while back, I was participating in a cutting edge open source project. I 
commented on a design feature, supplying a schematic, simulation results, and 
references to various related technical specs. The reply from one of the "big" 
players was that he had not read those thousand pages of tech specs, but surely 
I was wrong. He even opined why, saying what he "thought" the tech specs must 
say. He got support from some of his pet squirrels. I dropped out of the 
project.

This is not necessarily the norm...I'd like to think that it is a worst case. I 
know from personal experience that it takes a lot of time to understand a 
specific piece of hardware and its associated software. My company never went 
open source. I eventually closed it because I could not replace retiring 
professional staff from the current workforce. Not and keep the same level of 
quality.

I don't have the Elecraft experience to speak knowledgeably about all these 
discussions, but I certainly understand the level of quality that I see, and 
understand the pressures of modern economics. I can't think of one open source, 
community-based product that I'd want to hang my hat on, even if I do see some 
that I'd support. I just don't see the professional depth in the general 
community.

I'd actually vote in favor of opening the older Elecraft stuff up to community 
support, IF Elecraft went out of business or decided that some piece of gear is 
so old that it doesn't matter. (I actually own 2 pieces of gear that I'd love 
to see open source, but I don't see that happening.) Folks have invested a lot 
of $$ in their gear, and don't want to hear that 10 years later they need to 
toss it and buy new gear.

Re: [Elecraft] Firmware development

The Kenwood TS-590SG is ~$1300 new and you can get one in a week. Why are
you bashing it on the Elecraft list?

John KK9A


Rick NK7I rick.nk7i at gmail.com

And yet the TS-590 still has unfixed design flaws (overshoot being one of
the worst) without sending it to an authorized shop, taking weeks.

It was MONTHS before that firmware was updated (since originally reported).
I find the reaction time for updates with Elecraft to be more responsive.
Plus you can talk to a tech (except for COVID delays
now) the same day you initiate contact.

Re: [Elecraft] K3 FT8 Levels Sanity Check

[Bill Frantz]

Remember also, if the output level from the computer is too 
high, then it may not be possible to get the 4 bars steady, 5th 
flashing by adjusting the radio line in gain. This is because a 
change of one in the line in on the radio gives you either 4 
bars steady or 5 bars steady. Cutting down the levels from the 
computer will let you use more gain in the radio, getting to a 
place where the step size of the digital gain is smaller, giving 
finer control.

[Elecraft] Setting up new KPA1500 and find it mutes receive when ATU active

[Fredric Serota]

I find that when the ATU becomes active, it mutes the received sound a great 
deal. It does tune to a fine match, below 1.15:1. But regardless of band, as 
soon as it matches the received sound is way down. Don’t experience same when 
the ICOM transceiver tunes to the same antenna, all seems fine. Any help 
appreciated. This is a brand new unit right out of the box. I did upgrade to 
the latest firmware.

[Elecraft] KANT3 Replacement PC board

[David Olean]

I hope someone can steer me in the right direction. I was trolling 
through my junk and found a new un populated PC board.  I must have 
bought it from someone on the Elecraft reflector, but I have no memory 
of any of it!   All I have is the PC board and a printed sheet with a 
parts list.  By board has "Copyright Arcom 2016  KANT3 REV 1.0" printed 
on it.


The board has positions for 3 ICs and two small relays. It looks like it 
was made to route extra antenna connections etc. but I have no 
information on what it does or how it is implemented into the K3. Can 
anyone point me towards a description  on this accessory?  I could find 
no mention of anything with a google search.

operational condition.


Given the amount of nonsense I see on a lot of boards with respect to 
high end gear sales, I would welcome the serious buyer come to the shack 
for a first hand personal check out of the amp so the new owner can be 
100% satisfied of it's condition.


For those otherwise trusting buyers who don't associate my callsign with 
that of a scoundrel, I would be willing to do some driving for a meet up 
& hand off as part of the deal.  QTH here is about 30 minutes south of 
Kansas City, KS, in the lovely center of the propagation black hole here 
in the great USA.


$5400 OBO.

Those interested - kindly contact me off list to    jeff at ac0c dot com

Happy Thanksgiving and this year it looks like we will have some extra 
propagation on the CQ WPX CW contest this weekend as well to be thankful 
for.

Re: [Elecraft] KANT3 Replacement PC board

[Don Wilhelm]

Dave,

If I am not mistaken, that board would be installed in a K3 that did not 
have an ATU.


If you bought the K3 without the tuner and later installed the tuner, 
that would be the reason you have it in your 'junk'.

Re: [Elecraft] KANT3 Replacement PC board

[David Olean]

Hello Don and Carl,

I guess I was not very clear on this. I have a couple of K3s and all 
have a KANT3. I know what that board is. This board is a bare (un 
populated) board that was made by someone to be a replacement for the 
stock KANT3 but it has some added switching and routing capabilities 
apparently.   It was a non Elecraft mod kit for the K3. I vaguely 
remember saying that I was interested in the board after someone 
mentioned the design on the Elecraft reflector.  I ended up with a board 
and the parts list. I have no idea how to implement same!


To be clear, this is not a KANT3 from Elecraft. It is a bare board and a 
list of parts that includes three ICs (TPIC6C596PW) a 78LO5 5 volt 
regulator plus a bunch of capacitors and resistors. There are two 
antenna connections that go on the board along with the 20 pin connector 
that you remove off the original KANT3 board from your radio.


I am trying to figure out what this is and if it is usable.

[Nr4c]

I suspect it’s a way to have more than 1 antenna connection without the KAT3.

Re: [Elecraft] Sunspots!?!?

[Robert Cunnings]

A contrarian view of cycle 25 was recently published which predicts a peak 
SSN twice that of cycle 24:




The article has a link to the paper, it's worth reading. They propose a 
new criterion for predicting the strength of a cycle which in their 
interpretation predicts a very strong cycle 25. Maybe they are on to 
something, maybe not, but we'll have to wait until 2025 to find out. My K3 
is standing ready!

Re: [Elecraft] Firmware development

I own a popular open-source based 3D printer.  Finding the firmware to run the 
printer reliably is a challenge.  Once found (or so I thought) then there’s the 
task of compiling and loading the firmware after customizing specifically for 
one of 4 different mother boards the vendor shipped with the same printer 
model, using vague and incomplete recommendations from the “community".  Then 
there’s the matter of rounding up all the right libraries and versions used 
during the code ‘make’ when it fails.   Oh and it may require re-flashing a 
boot loader as it is susceptible to corruption for reasons I cannot get a clear 
answer on.  Once loaded to the printer, only then to discover it’s really worse 
than the version you hoped to repair, or dramatically changed in ways that 
demand relearning from the beginning.

I would have gladly paid $$ extra for non-open firmware that was supported by 
the vendor and just worked!!  I wanted to print - not test and debug code!

There is real value in proprietary, closed source…. particularly if it reliably 
brings the features and functions I purchased and is well supported by a 
responsive vendor such as Elecraft.

Kudos to the Elecraft Team!

"I can't think of one open source, community-based product that I'd want 
to hang my hat on, even if I do see some that I'd support.   I just 
don't see the professional depth in the general community."


Presumably you're talking about the amature radio community because 
nonprofessional collaborative open source software development in 
general is alive and very well, but even so how about N1MM+, or even 
WSJT-X and derivatives?  I could probably come up with other examples if 
I was willing to waste more time on it.


I think it would be insane of Elecraft to open up any of their products 
to open source development simply because of the chaos it would create 
for them trying to deal with users who busted their radios with buggy 
software that they probably wouldn't even admit to, but I also think 
your basic premise is flawed.
