NO! RTTY is LSB, and requires AFSK A. DATA A is USB, and is used for all 
other computer-generated digital modes.

Re: [Elecraft] Bluetooth Noise cancelling headphones

[Bill Frantz]

I have some noise cancelling headphones which I sometimes use to 
quiet airplane noise. They make it possible to listen to music 
without blowing out my ears from too much volume.


I always use them when our ARES/RACES group does communication 
for the Los Gatos Children's Holliday Parade. I can actually 
hear net control with a marching band next to me. (I also use a 
noise cancelling mic.)


I haven't used them during CQP, but the RadioSport headphones I 
used last time really kept the outside chatter down. They should 
be useful in a tent/room of SSB operators.


Since they work as normal headphones when the noise cancelling 
feature is turned off or the battery is dead, they are useful in 
many places.

Re: [Elecraft] Bluetooth Noise cancelling headphones

[Gary K9GS]

Thanks Kevin.  Did you order the same models as Dave?Interesting to read that 
the low latency features only work with their brand headphones. I believe I saw 
that on Amazon who also carrys the Avantree brand.   I'll probably get the non 
noise cancelling model headphones as I have a quiet shack.  Although now that I 
think about it maybe the active noise cancelling model would be good for 
traveling and FD/multi-op contesting. 73,Gary K9GS

So far as I am aware software shouldn't be changing. No CAT connection 
from rig to PC, just changing mode on the front panel of the K3 and 
sending tone in the LINE IN connector.

Re: [Elecraft] KAT-500 auto-tuning issue with SSB vs. CW

[Fred Jensen]

I will verify that this works exactly as Don relates.  You must "train" 
it by transmitting in every segment for each band/antenna combo you 
have, but once trained, it's solid. The segments are small on 160 and 80 
[10 KHz? I don't remember, someone on the list probably knows], and get 
larger as you go up in frequency becoming 100 KHz or so at 10 m and 
maybe twice that on 6.  With the KAT500 in AUTO, tune to the center of 
each segment, and press ATU TUNE if you have a K3, or just transmit if 
you are using a non-Elecraft transceiver.  It takes anywhere from 20 - 
25 or so watts to tune.


Once you have hit every segment with every antenna that works on that 
segment, switch to MAN and leave it there.  The KAT500 utility will let 
you specify which of the 3 antennas are usable on each band and won't 
put others in the antenna selection cycle.  To switch antennas, just tap 
the button to get the desired antenna. The selection of tuning 
parameters is as fast as it takes for the relays to close when you first 
transmit.  It worked fine for me when I still had my KAT500 on CW, SSB, 
and RTTY.  IMI: Operate in MAN, not AUTO.


If you have a K3/K3s and the cable between them installed and the KAT500 
connected, the tuner will follow your receive QRG, selecting the correct 
parameters as you tune, but the RF sense is nearly instantaneous without 
the cable or a K3/K3s.  IMI: Operate in MAN, not AUTO.  Every time 
someone has asked me to help them, and despite the "Operate in MAN, not 
AUTO" advice from this list and others, I get there and find they're 
operating in AUTO.

After training the tuner, when the KAT500 receives a burst of RF, it 
will tune to the remembered L/C combination for the frequency 
received, it will go immediately to that combination.

Train in AUTO mode, then switch to MAN for reliable operation.

Re: [Elecraft] Bluetooth Noise cancelling headphones

[Gwen Patton]

I have some nice Bluetooth active noise cancelling headphones. They're a
folding set made by MPOW that I don't think they make anymore. You can also
plug a 3.5mm stereo patch cable into them and not turn on the Bluetooth
section, though you can still turn on the active noise cancelling
separately.

I've used them with several devices and they seem to work well. I've used
then with the patch cord to the KX3 headphone jack, and they work just
fine, but that's scarcely a test. I don't know how I would test the
Bluetooth function with the KX3, as the rig doesn't have Bluetooth output
that I'm aware of. I'd have to use a separate Bluetooth transmitter, which
I don't currently have.

The headphones I used are these, that I purchased at the time on Amazon.
Unfortunately, they are no longer available.

These appear to be a more recent model with similar functionality.

But the OP says it did not! It seems pointless to continue the discussion if

[Elecraft] Bluetooth Noise cancelling headphones

[Dave Sublette]

Good evening,

A few days ago I posted a question about using Bluetooth headsets and the
latency problem.  I got no answers, so I just took the bull by the horns
and ordered something.

Today I received the Avantree Audikast aptX low latency transmitter and the
Avantree ANC031 Active Noise Canceling Headset.

After three hours charging the headset, per the instructions, I hooked it
all to the headphone output of my KX3.

It works!  There is no detectable latency.  I can send and receive Morse
without stuttering.  I can't hear any latency at all.

I walked the entire length of the house, about thirty feet in each
direction with walls, etc.  I can hear the receiver just fine.  One end of
the path is in the garage where my workshop is.  That gives the possibility
of listening to a fixed or scanned set of frequencies while I am working on
something else.

In short, it appears to be just what I wanted.  Now I won't try to break my
neck or drag all the radios off the table when I jump up to go get another
Pepsi out of the fridge.  :-)

No connection to selling these products here.  Just reporting the results
to to this point.

I may report again after I have used it awhile.  The battery charge is
advertised for 40 hours.  I'm sure I will put that to the test.

73,

Dave, K4TO

Re: [Elecraft] AX-1/K-2/K-1

[Dennis Moore]

I posted about this on 10/22. Here's what I wrote:

Here are a couple of observations on using the AX1 on the K2/10 with 
internal tuner. First off, I know that this is promoted for the KX2/KX3 
and similar radios, the AX1 page doesn't list the K2 as a compatible 
product and probably doesn't get much use in /PM.


With the K2 sitting flat, the AXB1 Whip Bipod legs aren't quite long 
enough to be effective. They do touch the table with maybe 1/2" of space 
between the legs. If you're using the K2 on an uneven surface they may 
not provide any support at all. I think another 1/4" - 1/2" of length 
would solve that. With the bail extended and the front of the K2 
elevated the legs work fine but of course the antenna is no longer 
perfectly vertical


K2 internal tuner tests were performed with the whip fully extended and 
the supplied radial wire laid out to its full length and tightened under 
the ground post as well as it could be. The pre-installed lug does not 
fit around the ground post. Switch position was appropriate for each 
band tested. On 20m the internal tuner found a good match wherever I was 
in the band. That is to be expected as the antenna was designed for 20m 
with no tuner. On 17m the best match I could get was 3.3:1, and on 15m I 
got a 1.1:1 match pretty much throughout the band.


I don't know what caused the issue on 17m since it worked fine on 20 and 
15. On my KX3 the AX1 tuned up fine on all three bands so I don't 
suspect an issue with the antenna, it must be the K2 tuner although it 
tunes other antennas well on 17m. I'll do some more playing around and 
if I get different results I'll post them.


73, Dennis NJ6G

Re: [Elecraft] Killed the KPA500 :)

[Michael Walker]

Knowing what I did while transmitting at 100 watts of msk144, I’m surprised the 
damage isn’t worse. 

The protection circuits did the best they could of. 

If you own any amp, you always need to be aware of the risk. I would never rely 
 on the automation to 100% protected any amp. 

If you are worried about your amplifier and anyway I highly recommend you have 
checklist handy every time you turn it on and change Bands. Never depend on the 
protection circuits. 

I know I’m preaching to the choir too many people, however it is imperative you 
understand exactly how your amp works, how it’s wired, and how it interfaces 
with any HF radio.

Re: [Elecraft] AX-1/K-2/K-1

[Don Wilhelm]

Bill,

I did not see my response on the reflector.

If you have a K2/10 with the KAT2 installed, it should work fine.
The K1 may have more trouble because of the more limited ATU range.
Use the tripod mount option and a short piece of coax.

Don W3FPR

Re: [Elecraft] KAT-500 auto-tuning issue with SSB vs. CW

[Don Wilhelm]

The KAT500, will do the same for any transceiver - except for following 
the receive frequency.
After training the tuner, when the KAT500 receives a burst of RF, it 
will tune to the remembered L/C combination for the frequency received, 
it will go immediately to that combination.

Train in AUTO mode, then switch to MAN for reliable operation.

Yes that's all wonderful if a K3, or some other means, provides the TX 
frequency to the KAT500. The OP does not say he is using a K3 and does not say 
that any other frequency interface is being used.


it was my assumption, based on the information in the first post, that RF 
sensing is being used and it is not working for the SSB phone signal.

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Afternoon,

   Yesterday's twenty meter net had fair to good reception on a clear 
band.  The forty meter net had a few moments of good reception.  Then 
propagation dropped off of a cliff.  Afterward I received a few emails 
describing what was heard on their end. Fine signals while I was 
starting up the net and then I disappeared.  Changing the time is once 
again in order.  Since 0100z is very close to forty meter's cutoff maybe 
thirty minutes earlier would be better.  Say 0030z for next week.  Any 
votes, advice, opinions, or sage apocrypha would be appreciated.



  On 14050.5 kHz at 2200z:

W0CZ - Ken - ND

K6XK - Roy - IA

K4JPN - Steve - GA

NO8V - John - MI

N5URL - Bob - NM


  On 7047 kHz at 0100z:

K0DTJ - Brian - CA

K6PJV - Dale - CA


   I am looking out the window to the east watching the sun work its 
way higher up the nearby mountain.  It is 3 PM and sunset is starting in 
the valleys.  Can't get used to this new time and it has been a few 
weeks.  We could stay with daylight savings time throughout the winter 
with no arguments from me.


   I got three snow reports yesterday with night time temperatures 
approaching zero.  However Roy reports feeling much safer in his 
community with a few inches of snow on the ground. With those 
temperatures I would be making friends with my plumber.


   Until next week stay warm and stay safe,

  73,

  Kevin.  KD5ONS

This still confirms the KPA500 is a darn near bullet proof amplifier.   
And likewise from the company, excellent support.


Glad the issue was only minimal damage.

Turns out that the first part of the 6M LPF took the hit on the amp
resulting in a CAP or 2 vapourizing.  AKA - phasers set to kill.  This
required no special electronic skills to find.  You could see it and smell
it.

The support team at Elecraft got back to me and the required parts to

Re: [Elecraft] Killed the KPA500 :)

[Michael Walker]

Just an update on the repair

Turns out that the first part of the 6M LPF took the hit on the amp
resulting in a CAP or 2 vapourizing.  AKA - phasers set to kill.  This
required no special electronic skills to find.  You could see it and smell
it.

The support team at Elecraft got back to me and the required parts to
repair the board are on the way.  Nice job guys.

Re: [Elecraft] KAT-500 auto-tuning issue with SSB vs. CW

[Don Wilhelm]

Rich,

Are you operating with the KAT500 in AUTO mode?
You should train the antenna (using TUNE) on all bands and all antennas 
at 25kHz intervals for each band.

Then change the KAT500 to MAN.

The KAT500 will follow your frequency and change to the pre-set L/C 
values for that band and antenna automatically.

If you have the latest firmware, it will even follow the K3/K3S in receive.

[Elecraft] EP6RRC using an Elecraft K2

[Bert Craig]

It's nice to see that one of their rigs is an Elecraft K2 (Likely a K2/100.) 
exciting a 700 watt PA. I worked them on 40 last night. I sure hope it was a 
K2-to-K2 QSO.

Re: [Elecraft] KAT-500 auto-tuning issue with SSB vs. CW

[Bob McGraw K4TAX]

There are SWR parameters that can be changed in the KAT500 Utility.  I 
suggest you install this on your computer, connect the KAT500 and 
initiate the application.


I have trained my KAT500 to use certain antennas on certain bands and 
for the lower frequencies, I have forced a tune ever 25 kHz. Then as I 
tune the VFO the values in the tuner change based on previous 
determinations.   This includes changing antennas based on band.  As to 
the difference in SSB and CW, I don't find any. Also, after doing the 
training, I normally operate the KAT500 in the MANual mode.


Also in the K3S manual, see KAT3 topic, page 60, for information on 
establishing VFO tracking with the KAT500.  When VFO tracking is 
enabled, the KAT500's L network will be continuously updated as the VFO 
is tuned.

I don't expect my KAT500 to re-tune with an SSB transmission since I send it 
the exact TX frequency before I start to transmit. However, it is my

I'd suggest a review of the KAT500 Serial Command Reference. Values can be

[Elecraft] [OT] How much is it worth?

[K2QI]

Have a K3 that's pretty much fully loaded.  When I get back to my home in PA
later this week, I'll check the rig and invoices but I'm pretty sure it's
configured as such:

1. K3/100
2. KAT3A 
3. KDVR3
4. KBPF3A
5. KRX3A
6. Crystal filters for both main and sub receivers
7. And I think the K144XV is installed but can't recall.

If memory serves, I paid close to $5k for this configuration several years
back.  Unfortunately I need the money and will most likely have to sell. 
That said, I'm not sure what it'd be worth today.  I'm open to suggestions
(and offers if interested).

73,
James K2QI

Depending on the chemistry, Li-Ion cells can be something like 3.2 to

a low dropout linear regulator to limit the voltage to 14 V.  With a

The K3 TX EQ works better if you cut, rather than amplify. Start off by 
cutting everything below 500 Hz all the way down. Then experiment with

Re: [Elecraft] KX2 battery options.

[Detrick Merz]

I've done both, for my KX3, using cells salvaged from old laptop batteries.

4 cells: at full charge, pack voltage is too high for the KX3. On the flip
side, nominal pack voltage will remain high enough for the radio to operate
at higher power until the pack is nearly dead. I've dealt with this two
ways:

1) only charge the pack up to ~15.5v. This keeps the peak voltage within
the acceptable range, but sacrifices some capacity. It may also increase
the longevity of your cells (i.e. allow more charge cycles). It may also
prevent any cell balancing from ever happening.

2) Charge the pack fully and use a buck  converter until pack voltage falls
off a bit. This will allow you to maximize the pack capacity but keep the
input voltage where the radio wants it. The downside is the possibility of
birdies (buck converters are switchers) and having to carry yet-another
thing. Some power is "wasted" by the buck converter, but it can be removed
from the equation pretty quickly (it doesn't take terribly long for the
pack voltage to drop to where the radio is happy).

3 cells: peak pack voltage is perfectly acceptable for the radio, but may
not allow operating at full power. Nominal pack voltage (11.1v) also won't
allow full power out. When the pack is near dead, output power may need to
be significantly reduced. I've dealt with the 3 cell pack by using a boost
converter. This allows for higher output power but sacrifices efficiency
(some power "wasted" by the boost converter), and may result in birdies
from the converter.

Since I already have both 3- and 4-cell packs, I use both of them. I ended
up picking up a boost-buck converter. It's pretty small (deck of cards),
and hasn't created any RFI that I've noticed yet -- even operating out in
the field where the noise floor is very low. It lets me use either pack on
the input side, and set the output voltage where I like. I can run the KX3
at 15W until the packs go dead. I've also used it with my Bioenno LiFePO4
pack if I needed a little more power to complete a contract.
