### I used that as an example of the state 
I find sometimes find the K3s in. There is 
something unique to WSJT-X that no other 
software does that makes this happen, I 
only find it randomly if I am using 
WSJT-X. Never experienced it before WSJT-X 
and never with any other 
situation/software.

### WSJT-X is the only software I use that 
does this. The others share control as in 
N1MM and MMTTY, Logic & FLDigi working 
fine together. Logic runs beautifully with 
N1MM and MMTTY, no conflicts of any kind. 
If they can do this flawlessly, it is not 
unreasonable to expect WSJT-X to play nice 
as well.

### I disagree. As is so often the 
situation when someone has an issue with 
Company A's product and Company B's 
product is being used and there is a 
conflict... the stock answer is that 
problem belongs to the other company, ask 
them what to do. It's an old saw and in 
this case, I'm told I should ask on the 
other list. Everyone feels it's the other 
guy's fault and that question belongs 
elsewhere. Ask there and they tell you how 
the K3 is non standard and to ask on the 
Elecraft list. The person in the middle 
gets trashed on both sides. I've 
experienced this for so long I've come to 
like trash.

As I said in the words below, I was asking 
on the Elecraft list if others had 
experienced this problem. My original 
statement was: "Anyone experience this and 
figure out how to prevent it?"

Where better to ask than a place devoted 
to this type of radio if others have the 
problem and if so, how to resolve it. 

When I first started with WSJT-X I asked 
on the WSJT-X reflector and was told quite 
clearly if I want to use it, I had to run 
it directly to the port for the K3, no 
other control software should be running 
at the same time and if I wanted to use 
logging I had to use JT Alert and have my 
logging done via that. I was also told 
virtual ports are nothing but trouble, not 
to use them with WSJT-X and there is no 
help for those that use them. It seems to 
me there's a lot of attitude on that list.

FWIW, I did find I can use a virtual port 
with it # "10" If I assign any other 
numerical value it will not work. Won't 
work with Win 7, I tried for hours but 
with this computer & Win 10, WSJT-X works 
on virtual port 10. All the other software 
works on whatever virtual port I tell it 
to work on. WSJT-X is not yet user 
friendly, I suspect it will become more so 
over time. 

If I had the skills I would be happy to 
help make that so. My skills lie in other 
areas; want someone to help keep you alive 
following a traumatic injury? I can do 
that. Write software? I can't do that.

That's because "Test PTT" in WSJT-X is a *TOGGLE*
exactly like the XMIT button on the front of the
K3.  By clicking "Test PTT" only once, you are
placing the K3 into transmit and *NEVER* switching
it back to receive!  WSTJ-X and the K3 are both
doing *exactly* what you told it to do.

WSJT-X is not buggy.  The radio control interface
does not handle asynchronous data and it was not
designed to do so.  That means you *must* disable
AI1; (set AI0;) in the K3 command (no automatic
information reports) and *MUST NOT* share control
of the K3 with any other software - where that
software will poll the K3 and cause it to generate
any unexpected data to hamlib (the WSJT-X control
module).

Your complaint really belongs on the WSJT-X list
and not the Elecraft list.

I am a novice at WSJT-X but I can't help
but feel that it is a program that is
genius but immature. I say this expressly
because I run N1MM, MMTTY, logic 9 and my
GPSDO all with LP bridge but WSJT-X wants
to have total dominion over the operating
system as far as the ports go.

I have found a way to finagle it to work
with LP bridge but not because WSJT-X has
any interest in that being the case.
Considering how many people are having
trouble with ports and that program, it
seems like the problem to me is within the
program itself and how it approaches using
ports. If the other programs can use the
virtual ports without issue, it doesn't
make sense that WSJT-X has to have
dominion. I'm sure that after enough
complaints and enough time, that the
authors will attend to this problem.

It is only when I use WSJT-X that I have
the issue that I mentioned in my initial
post which is hanging of the transmit
function without sending RF out the
antenna. No other program or situation
causes this to happen, only WSJT-X so as
far as I'm concerned it is a buggy program
but a genius program at the same time,
what it does is amazing and it is free no
less. My only interest in posting was to
find if somebody has found a way of
getting around this bug.

When it comes to the idea of RF getting
back in the shack, I never get any RF back
in the shack to disturb anything when I
use my antennas that are almost 400 feet
from the house using 1 inch hardline get
to them. The only time I ever have any
issue with RF in the shack is if I use the
tri-band on top of the house and I rarely
use that because of RFI in the
neighborhood.

For this transmit-state issue to happen
when I am running barefoot to an antenna
almost 400 feet away which is tuned
beautifully and I need no transmatch and
me running barefoot... it is not RFI in
the shack causing this problem. I do lay
it squarely on the shoulders of the WSJT-X
software for it never ever happens at any
other time then when I am running this
specific software.

I really don't want this topic to run to
the point that it becomes something Eric
has to shut down so maybe it's best just
to leave it and I will keep pushing a
button on the front panel to unlock the
transmit condition when it engages when
WSJT-X goes rogue.

The only way I can reproduce the problem
every time ( And FWIW, PTT-Key is set to
off-off) is to go into the WSJT-X
settings, select Radio, click on test PTT
and it creates this exact condition. If I
exit settings without clicking on Test PTT
again to shut the state off, the K3s is
then left in this transmit state with no
RF being made.

The solution is to tap a button on the K3s
front panel and all is fine again.

The problem appears to me to be a still
buggy WSJT-X issue that the authors have
not yet become interested in attending to.
I would just like to know how to have a
workaround to get around this error until
they fix it. As it is it has become
tiresome.

For those using WSJT-X, sometimes I find
the K3s is locked as transmit but there is
no RF being sent and no Rx from the K3.

Looking at the P3 I see a jitter on the
upper half of the screen as if there was a
tiny output but no Rf is seen on any of
the three SWR meters in line (K3s, AP3 &
LP-100A).

I couldn't get WSJT to receive, looked at
the settings, all were correct and as is
sometimes needed with WSJT-X, I rebooted
to get it to work 

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

[Tom]

Hi,
Just hooked up a sniffer to WSJT and the PTT CAT commands  are correct, 
putting it into transmit when appropriate and out as well. (Unless there is 
an intermittent bug).
If the radio menu for PPT-KEY is OFF-OFF it cannot get put into transmit via 
hardware.  So, DTR signals do nothing.  There will be no issue when you 
power up your PC etc.


Since the K3 will go into transmit anyways, the most likely item then is 
LPBridge (which the OP said he was using)  OR VOX is enabled on the line-in 
in the rear and the sensitivity is just too high.

For those using WSJT-X, sometimes I find
the K3s is locked as transmit but there is

Looking at the P3 I see a jitter on the
upper half of the screen as if there was a

LP-100A).

I couldn't get WSJT to receive, looked at
the settings, all were correct and as is
sometimes needed with WSJT-X, I rebooted
to get it to work properly but it still
did not lock onto the K3s frequency.
Rebooted again and then I realized the K3s
was in that TX condition with both the red
& yellow LEDs lit and that jitter on the
P3 upper screen.

This happens every so often and what I
have to do is touch any of the buttons on
the K3s and it disengages this situation.
I did that to deal with the issue I
mentioned above. I could restart the K3s
but then I'd have to restart LP-Bridge and
wait, so I use the quick fix.

Anyone experience this and figure out how
to prevent it?

Thanks!

Re: [Elecraft] KPA500 Problem

[Kevin der Kinderen]

I've done some testing. I have a good selection of Times LMR-400-ULTRAFLEX
jumpers that I stocked up on from MPD Digital. Never had a problem with any
of their cables and so far it's looking like they are all good.

I set things up as Radio <--> KPA500 <--> DL1500 with new cables in between
and the KAT500 removed from the chain.

Running the radio to 10 watts the radio showed 1.25:1 SWR while the amp was
in standby. When in operate, the SWR on the radio maxed out.

I fired up KPA500 Remote and bumped the radio up to 20 watts. In standby,
radio showing 1.25:1 SWR KPA500 remote reported

Power: 18 w (that's typical)
SWR: 1.1:1
Current: PTT OFF (typical in standby)
Voltage: 74.8
Temp: 22 C

Switched the amp to operated, radio still at 20. KPA500 remote reported

Power: 0 W
SWR: NO RF
Current: PTT OFF
Voltage: 74.8
Temp: 22 C

It's like standby/operate is switching between straight-through and open.
It seems to be falling into place with Brian's description of his recent
problem. I heard no cracks, booms, or sizzles. Smelled no smoke or ozone.
It just started giving me problems intermittently and seems to have finally
settled down into a broke state.

Working with Elecraft to troubleshoot and will share any findings that
might be helpful or garner sympathy. ;)

Re: [Elecraft] KPA500 Problem

[Bob McGraw K4TAX]

On PL-259 connectors, make sure they are more than finger tight. I use a 
pair of 4" Channel Lock pliers to snug mine after they are finger 
tight.    Today's PL-259's may look good but indeed with many of them 
today,  the plating is crap!.  Same for coax cable and the way it gets 
terminated inside the PL-259.   The cable frequently works loose and 
causes intermittent connections which may not show up at 100 watts or less.


In my practice, if I find a bad cable, I immediately chop the suspect 
PL-259 off of one end.  That way the cable can not be accidentally used 
until it is properly repaired and checked with a dummy load and my 
impedance bridge or antenna bridge.

Damn it Don! *DON"T TELL USERS HOW TO USE MICROHAM PRODUCTS*
The microHAM instructions are very clear - *NEVER USE CAT FOR PTT*
YOU HAVE NO BUSINESS HANDING OUT INSTRUCTIONS THAT VIOLATE THOSE
OF THE MANUFACTURER.  How would you like it if I told Elecraft users
to run their transceivers at 24 V to minimize IMD in the power amp?

Using CAT for PTT results in hot switching of amplifiers, antenna
relays, and other devices like antenna preamps while using hardware
PTT assures proper operation of sequencing circuits that assure
audio, external antenna switches, amplifiers, etc are switched *before*
the transceiver is placed into transmit.

Even the K3 PTT to RF delay is not sufficient to accommodate switching
delay in old amplifiers, EME sequencers or the LNA/preamp bypass relays
for external (active) receive antennas.


Are all those having a similar problem using MicroHam something? or
does it occur with other interfaces.

It occurs with other manufacturers products and CAT PTT - nearly every
manufacturer has a race condition in their controls when CAT and
hardware are mixed.  Since CAT PTT has serious problems with hot
switching and most software includes specific PTT to CW and PTT to
Audio delays specifically to avoid hot switching, use of *HARDWARE*
PTT is always the smart choice.

The CAT and PTT are on different COM ports, per the installation

stray RF problem as I have all the equipment bonded together, ferrite 
cores on the audio and control lines, a line isolator in the feedline 
where it enters the house, and line isolators between the rig and amp 
and between the amp and antenna tuner.  The lockup happens when 
running only 30 watts with FT8.  It never happens when running a KW 
on many other modes.  I run RTTY, PSK and other digital modes with no 
problems.


Thus, I suspect the issue is associated with the WSRJ-X software as 
the same issue occurs with various transceivers in multiple locations.

Re: [Elecraft] K3S RX antenna switching questions

[Don Wilhelm]

Steve,

I suspect that increasing the TX Delay will *not* fix that problem.
Since at greater than 50 watts, you hear relays clicking indicates that 
the K3S COR is being activated.
The solution is to either move your RX antenna further from the TX 
antenna or use some device that disconnects or grounds the RX antenna 
while transmitting.

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

Damn it Don! *DON"T TELL USERS HOW TO USE MICROHAM PRODUCTS*
The microHAM instructions are very clear - *NEVER USE CAT FOR PTT*
YOU HAVE NO BUSINESS HANDING OUT INSTRUCTIONS THAT VIOLATE THOSE
OF THE MANUFACTURER.  How would you like it if I told Elecraft users
to run their transceivers at 24 V to minimize IMD in the power amp?

Using CAT for PTT results in hot switching of amplifiers, antenna
relays, and other devices like antenna preamps while using hardware
PTT assures proper operation of sequencing circuits that assure
audio, external antenna switches, amplifiers, etc are switched *before*
the transceiver is placed into transmit.

Even the K3 PTT to RF delay is not sufficient to accommodate switching
delay in old amplifiers, EME sequencers or the LNA/preamp bypass relays
for external (active) receive antennas.


Are all those having a similar problem using MicroHam something? or
does it occur with other interfaces.

It occurs with other manufacturers products and CAT PTT - nearly every
manufacturer has a race condition in their controls when CAT and
hardware are mixed.  Since CAT PTT has serious problems with hot
switching and most software includes specific PTT to CW and PTT to
Audio delays specifically to avoid hot switching, use of *HARDWARE*
PTT is always the smart choice.

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

[tomb18]

Wstj-x has a lot of issues communicating with rigs. What I have found is For 
example, on the k3, it will change modes before it changes bands. The result, 
when you are on the new band you are in the wrong mode. On the Yaesu ftdx 
radios, it puts the radio into USB instead of data mode for transmit, and rtty 
mode for receive. It does not handle split correctly on the ftdx radios either. 
This is more important for yaesu rigs because they can have per mode parameters 
for gain and so on. It is quite possible it is doing something wrong when it 
comes to Dtr control. On the other hand you can try to use the omnirig entry in 
wsjt x for control, but it also has mode issues. Not sure about the k3. That 
may work better. 73 Tom

WSJT-X can run split.  In split mode,  it will adjust the Tx frequency so
that the audio tones are always near the middle of the the passband.

I had a similar problem recemntly due to a SC diode in the TR switch, all OK
on bypass but not on operate. After changing diode (and checking associated
bits I has problems with power/dissipation on 10 and 6m cured by using a
diode from a different batch.

However, after re-assembly I had intermittent lack of RX, traced to a relay
card used externally for buffering a relay. At the time this board was
unpowered but still in circuit and was holding the KPA500 on TX. A simple
bypass proved it was the culprit and putting its 12v power back on fixed it
for good.

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

[tomb18]

What Joe, eluded earlier is actually true in some cases. Software can bombard 
the serial port with so many commands, without  listening  to a response and 
then issue the cat command. The problem there is the radio is processing all 
the other commands and the PTT is delayed. 
In wsjt if you are using it alone with the native cat support and a k3, the 
data rate is very low, not like  something like n1mm. There you can use the cat 
commands for Ptt without any issues. On the other hand, just turning the 
computer on can toggle the dtr and thus the radio can go into transmit. There 
it requires disabling advanced parameters in the serial port drivers, to turn 
off interrogation of ports. 73

[Elecraft] K3S RX antenna switching questions

[Steve Steltzer via Elecraft]

Here's the setup : 3 month old K3S. Full wave 80 mtr RX loop. Closest point to 
TX antenna is around 200 ft. Over 50 watts I hear relays clicking and stations 
have a hard time breaking in even using QRQ plus. I assume the RX antenna is 
not switching fast enough and I'm getting  milliseconds of high RF into the 
front end and protection relays are kicking in??? 
Will increasing TX delay help this? If so, how much can I increase it from the 
factory setting of 008 before the keying gets choppy running 50 to 60 wpm? Are 
there other settings that would affect this? I also run an Acom 2000A from time 
to time, which has pin diode T/R switching and, according to reports, does QSK 
perfectly at those speeds. I don't want to mess that up either.
Thanks,Steve, WF3T

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

[Jim Brown]

Not necessarily true. If, for example, equipment in the shack is not 
properly bonded together, an antenna close to the shack will put a lot 
of RF in the shack, which will induce RF onto cables connected to 
equipment, and is likely to couple into equipment. If an antenna is 
working as an antenna and it's close to the shack, it WILL put RF in the 
shack -- that's what it is intended to do!


Proper bonding is described in this set of slides

http://k9yc.com/GroundingAndAudio.pdf

and in N0AX's new ARRL book on Power, Grounding, and Bonding

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

[Don Wilhelm]

Richard and all,

The proper place to cure "RF in the shack" problems is in your antenna 
system.  A good common mode choke (many call it a balun) in the antenna 
feedline and running the feedline at right angles to the radiator 
(assuming a dipole) to keep the feedline from picking up radiation from 
the radiator.  If that physical configuration cannot be avoided, then an 
additional common mode choke at the shack entry point can help.


In the case of off-center fed antennas and end-fed antennas, often the 
common mode current on the feedline can be difficult to cure.  Use of 
one or more of the effective "baluns" described by Jim Brown K9YC at 
http://audiosystemsgroup.com/RFI-Ham.pdf will help.


With effective common mode chokes on the antenna and feedline, you 
should not have to use ferrites on every cable in the shack - a much 
more sane answer IMHO.

I've seen this occasionally too. I've had a number of odd malfunctions

ferrite rings, with as many turns of the cable as would fit, at the

You may be putting the performance of your station at a disadvantage
with that approach, compared to using WSJT-X with CAT to keep TX audio
in the range 1500-2000 Hz.

The roofing filter may have a fair amount of group delay inequality at
the edges of the passband, which can lead to inter-symbol interference
on digital modes. I don't know how serious, if at all, this is in
practice, but I know one very clever engineer who regards it as enough
of a problem to have had a custom roofing filter manufactured for his K3
to reduce it. He mainly works EME with JT65.

I've seen this occasionally too. I've had a number of odd malfunctions
of USB-connected devices in the presence of RF. I now have fitted
ferrite rings, with as many turns of the cable as would fit, at the
computer end of the all the USB cables going into the PC.

Re: [Elecraft] KPA500 Problem

[Kevin der Kinderen]

Hmm... alright then. Jim sent me an email with the same conclusion. I need
to recheck all my cabling.

I'm a bit surprised that's the conclusion as simply bypassing or turning
off the amp but leaving it connected made the problem go away. I have some
good cable on there now but can replace each one of them to try it out.
I'll report back later on. I really hope it is just this.

Re: [Elecraft] KPA500 Problem

[Michael Walker]

Hi Kev

Don is 100% right.

I would change all the cables and then test with the amp alone and the
tuner alone to narrow it down.

I spent 3 days debugging an Acom A1000 issue only to finally out I had a
bad jumper cable.

Re: [Elecraft] KPA500 Problem

[Don Wilhelm]

Kev,

That behavior can be caused by a coax jumper, either loose or faulty in 
some way.  Make sure the PL-259s are tight and if you can substitute the 
jumpers with known good ones - particularly the one between the KPA500 
and the KAT500 and the one between your transceiver and the KPA500.

There are as many problems caused by cables as are caused by equipment.
Some cable problems have no apparent problem at lower power, but rear 
their ugly head at higher power.
You could also have a higher power problem with your antenna.  Switch to 
an alternate antenna or dummy load if possible (tune the KAT500 into the 
dummy load) as a test.

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

[Joe Subich, W4TV]

> Play it safe, just use software Ptt for everything.

BS!  Many rigs have race conditions in their processors.  *NEVER* use
software PTT and stick to hardware (RTS) switching only - particularly
if you have the need for external sequencers and audio switching.

If you have a problem with hanging PTT with hardware switching, fix the
common mode RFI issues in your shack!  If you don't fix them now, they
will bite you later (and somewhere you don't expect).

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

The menu option in the K3 is PTT KEY.  If you set this to OFF-OFF then you 
won't have any issues with transmit coming on when you don't want it.  Just 
make sure you use CAT based PTT in your software and you are good to go.

[Elecraft] WSJT-X K3/K3s hanging as Tx 
For those using WSJT-X, sometimes I find 
the K3s is locked as transmit but there is 
no RF being sent and no Rx from the K3. 

Looking at the P3 I see a jitter on the 
upper half of the screen as if there was a

the three SWR meters in line (K3s, AP3 & 
LP-100A).

I couldn't get WSJT to receive, looked at

sometimes needed with WSJT-X, I rebooted 
to get it to work properly but it still 
did not lock onto the K3s frequency. 
Rebooted again and then I realized the K3s 
was in that TX condition with both the red 
& yellow LEDs lit and that jitter on the 
P3 upper screen.

This happens every so often and what I 
have to do is touch any of the buttons on 
the K3s and it disengages this situation. 
I did that to deal with the issue I 
mentioned above. I could restart the K3s 
but then I'd have to restart LP-Bridge and 
wait, so I use the quick fix.

Anyone experience this and figure out how 
to prevent it?

I've been using WSJT-X since it was first introduced several years ago, 
and I've never had this problem. I've always used VOX to put the rig in 
TX mode, as I do with SSB and all digital modes. I've often run with a 
power amp that uses a vacuum relay for T/R switching, and there's 
sufficient delay within the K3 and K3s for the amp's T/R relay to switch.

Re: [Elecraft] WSJT-X K3/K3s hanging as Tx

[Don Wilhelm]

Bert and Gary,

Have you looked for a computer problem?  Such as having both PTT via 
command and via an RS-232 signal line?  Do you have both VOX on and 
another means of keying the transceiver?

Subject: [Elecraft] WSJT-X K3/K3s hanging as Tx

For those using WSJT-X, sometimes I find the K3s is locked as transmit but
there is no RF being sent and no Rx from the K3. 

Looking at the P3 I see a jitter on the upper half of the screen as if there
was a tiny output but no Rf is seen on any of the three SWR meters in line
(K3s, AP3 & LP-100A).

I couldn't get WSJT to receive, looked at the settings, all were correct and
as is sometimes needed with WSJT-X, I rebooted to get it to work properly
but it still did not lock onto the K3s frequency. 
Rebooted again and then I realized the K3s was in that TX condition with
both the red & yellow LEDs lit and that jitter on the
P3 upper screen.

This happens every so often and what I
have to do is touch any of the buttons on the K3s and it disengages this
situation. 
I did that to deal with the issue I
mentioned above. I could restart the K3s but then I'd have to restart
LP-Bridge and wait, so I use the quick fix.

Anyone experience this and figure out how to prevent it?

Thanks!

Re: [Elecraft] kxpd3 question

[Eric J]

Knowledge of Morse code was an international requirement, but there was 
no speed requirement.

Anyone who remembers the "incentive licensing" debates of the mid-60s 
knows the Morse requirement in the U.S. was clearly intended to be 
restrictive by many hams if not most. Incentive licensing intentionally 
took away privileges with a code speed requirement that persisted until 
the fairly recent no-code licensing.

I've always been a cw op. I lived in Japan when I was 12 and heard hams 
talking on my SW-54. I had no interest in that at all until I learned 
about hams using Morse code. I've been 90%+ CW since. Definitely not by 
choice, but I took General, Advanced and Extra before FCC examiners in 
Boston and Long Beach.

Re: [Elecraft] kxpd3 question

[Lynn W. Taylor, WB6UUT]

I'm no sure I'd say it was to be "restrictive" but I will say there is a 
benefit to making sure someone wants a license vs. mailing in boxtops 
from their favorite cereal.


I'm probably one of the young guys here, at 60.

I made it to 5wpm and got my Novice, but never got past 10wpm.  Took the 
general written to get my Technician, and when the 13wpm requirement was 
dropped was "grandfathered" to General.  I currently hold an Extra Class 
license.


Going back to my Tech. days, I never fell in love with code, spent a bit 
of time on 2m FM, but very early got into RTTY.  Ran autostart on the 
SDTS repeater on 220 with a model 15 and later a 28KSR.  Was a TAPR beta 
tester, and probably still have my BETA TNC.


I like PSK-31.

So, when the CW vs. Phone arguments crop up, my response is pretty much 
always going to be NEITHER!

Re: [Elecraft] CW

[Phil Hystad]

I was a shipboard comms officer for several days, part of mornings actually -- 
well, not officially and definitely not paid the big $$$.

When I was 14 and my copy speed about 20 wpm back then, I spent two weeks on my 
dad's ship (he was Captain of a cargo ship).  I hung out in the radio room 
quite a bit and the radio officer showed me how to fill out the weather report 
each morning as it was sent out over the Pacific by the marine weather 
reporting services (whereever they were, I can't remember).  So, I would sit in 
the radio operators chair, dial up the frequency on the receiver, and copy the 
CW weather broadcast.  I made a few mistakes at the beginning until I got use 
to the format and content.  After that, each morning I had the job of copying 
and writing up the weather report for our area (pacific northwest coastal 
areas).

I also learned a lot about navigating, taking sitings, plotting the charts, and 
I even spent an hour at the helm trying to sail a straight wake -- definitely a 
learned skill I did not totally learn.

Re: [Elecraft] kxpd3 question

[Edward R Cole]

The purpose of requiring CW was perhaps not to be restrictive - but 
it had exactly that effect.


I was twelve when I discovered "hams" talking on 75m AM.  It was not 
the morse code that attracted me to ham radio - it was talking.


But I quickly found out that the gate to getting into ham radio 
required learning morse code.  I got 5wpm pretty easy and became a 
Novice at age 14.  A year later I took the General Class written exam 
and became a Technician.  Several attempts to pass 13wpm which 
involved a 68 mile drive to FCC in Detroit resulted in failure.


I started college as an EE student, way too busy for working on code, 
graduated to start my career which included nine years working for 
JPL-NASA where I became a senior engineer at age 32.  I got to help 
several missions to the planets, but I was "not qualified" to be a 
"real ham" because of code.


Finally in 1982 (age 38) I spent the effort to pass the 13wpm test 
(which then only required answering 7 out of ten questions vs 1 
minute perfect copy of five character random groups).  I took my 
Advanced test and passed (never had a General).  In 2000 FCC lowered 
speed requirement for Extra to 13wpm and I passed with two wrong 
answers.  BTW I took and passed the 2nd Class Radiotelephone in 1971 
(which is way harder than extra).


24 years I had to wait to become a "real ham".  Well the good result 
was that I got interested in 2m (where I could talk) and that lead to 
microwaves and eme.  EME required CW when I started in 1998 but 
fortunately digital arrived (JT44) in early 2000's which I have been 
using on 2m and a little on 1296.  I will eventually get up to 15wpm 
because I want to work eme stations that only do CW.


But as a boy, I just wanted to talk on ham radio.  Eliminating CW as 
a requirement does make it easier today.  Longevity of ham radio does 
not depend on it.  My local club has only 2-3 members that are not 
retired.  No youngsters under 35.


I am currently learning about using a Raspberry Pi in a autotracking 
system for my eme antennas.  Plans to install dual-yagis for 6m-eme 
and a 100w 3400-MHz system on my 16-foot dish.  Guess some of the 
engineer remains, as well.

For at least the last 20-30 years of the 20th century, CW was used as a
means of keeping the hobby "pure," a "rite of passage" that all current
licensees had had to take, and that, anyone else wanting to enter their
hallowed ground must also take. You had to be not paying attention not
to be aware of this. It was easy to not be paying attention -- many of
us, including me, were on and off the air for decades at a time as we
lived our lives with jobs, families, even other interests. This was not
unique to the US -- the CW requirement was from international
governmental bodies.

[Elecraft] CW

[Eddy Avila]

Guys, I'm old enuf when CW testing was required by the FCC for any license 
grade. Commercial CW Ops could make really good $$$ as a shipboard 
communications officer, I mean really good bucks! Much better than slinging 
hamburgers at MacDonalds...wait, I'm not sure the Big Mac was available 
back then.


Anyway, enjoy whatever mode floats your boat.I'm into FT8 lately, but I'll 
get bored with it soon and go back to dits and dahsif I can find anyone 
on the air in that mode.


Just get on the air, for heavens sake!!!

Re: [Elecraft] [K1] Looking for KAT1 built/unbuilt for my son

[Petr Ourednik]

Don,

thanks. Even although I ordered it at the time when this item has been
available on the web they said "gone". Then after it disappeared from
the web several weak ago. So no way thru Elecraft.

Many thanks,

73 - Petr, OK1RP

Petr.

Contact sa...@elecraft.com to see if they have any left.  Even though 
the K1 has been discontinued, they have said the options will remain 
available until stock is depleted.

The Elecraft T1 is an alternative.

[Elecraft] OT - Intro to FT8 powerpoint presentation

[Larry (K8UT)]

Several weeks ago there was a series of reflector posts by hams looking 
for materials on FT8 to use in PPT presentations. I had offered to post 
my slides after delivering to the SEMDXA club meeting on 11/10.


The 27 MB ZIP file contains the .pptx file, two videos (stand-along and 
log-integrated operation) and a README file.


www.semdxa.org >File Gallery >Presentations, "Intro to FT8 presentation 
by K8UT"

or
http://www.semdxa.org/download/presentations/IntroToFT8_presentation_byK8UT.zip

Anyone is welcome to cut/copy/plagiarize as they require. Corrections 
and comments would be appreciated - direct to my email address.

[Elecraft] Another wanted KXV3/3A oh and a KSYN3

[Martin Sole]

Hi,

VE2EBK seems to have found a KXV3 easily enough, wonder if there is 
another one out there? I could certainly use it and can do PayPal easily 
with postage to a US ham address (QRZ.com verified).


Let me know what you have and would need for it.

Also want a KSYN3. Now surely there must be a bunch of these somewhere 
:) I want to put a second receiver in my K3 but honestly cannot justify 
the extra for the KSYN3AUPG at the this time, I know they're good but...


Again, let me know what you have and lets see if we can work a deal.

Many thanks,

Martin, HS0ZED
