Re: [Elecraft] K3 + MicroHam MicroKeyer + Heil Proset

[Ray G3XLG]

Hi Tom

I'm not sure if you sorted your problem or not but i thought I'd reply as I
have similar setup - K3+P3 +MicroHAM MicrokeyerII+ Heil Proset K2

First I would connect the Proset phones & mic with the PTT Mic lead
(connected to a footswitch or other switch) to the FRONT of the K3, ignoring
the MicroKeyer. If it all works there, then the Proset, foot switch & mic
are all working OK.

Normally I plug my Proset into the back of the Microkeyer using the
Microkeyer short cable supplied & the ptt switch adaptor that came with the
Proset connected to a footswitch as before. I plug the phones into the back
of the K3 which keys the transmitter fine.

Re: [Elecraft] Kx3 power output

[Chip Stratton]

I think the usual preferred method for getting maximum PSK power
output is to set your transmitter for its maximum potential power
output, but adjust PSK modulation to a point below which ALC
activation (and hence signal peak clipping) is not occurring. As Rich
says, this typically will be at an average power output of one half
what the transmitter is capable of delivering in CW or RTTY mode. An
PSK IMD meter would be ideal, but using this method seems to work
fine. I do not have a K3, but with my IC-7000 I use this method,
though usually setting modulation levels such that average power
output is in the 20 to 40 watt range if I'm trying to reach a
difficult station.

Perhaps the adjustments on the K3 and KX3 are different if using
built-in PSK modulation?

Thanks.  I got it working and am using the same set up as you.  My

[Elecraft] K3 Utility 1.4.10.11

[Mike Harris]

G'day,

Just installed 4r48 for no other reason than I like to keep up to date. 
  No K/0 on my horizon.

I was surprised and somewhat alarmed to see during the MCU upload not 
only the usual progress bar but a rapidly scrolling window with status 
messages.  I can't remember all the detail but it included responses, 
times in ms and a whole string of characters presumably relating to data 
blocks.

To my recollection I've not seen this before.  Running Win7/64 with 
latest updates, as of two days ago.

Final result is all seems to be OK.

Regards,

Mike VP8NO

Re: [Elecraft] Kx3 power output

[Richard Ferch]

Chip,

While this method of control for PSK31 (set power to maximum and use 
audio drive controls to adjust output) works well with many rigs, it 
does not work with the K3. If the ALC meter is showing fewer than 4 
bars, output power will be unstable, and if the power control is set to 
maximum, the K3 will do its best to achieve that power level, which is 
not what you want.

With the K3 in DATA A (or AFSK A), the recommended procedure is to set 
the audio drive at the level that results in 4-5 bars on the K3's ALC 
meter, and then use the PWR control to adjust the output power. You can 
think of the 4-5 bar point on the K3's ALC meter as the point where ALC 
is just starting to activate.

With the K3 in PSK D mode, neither of these methods is possible. In PSK 
D there is no audio drive to adjust; the only control available is the 
PWR control.

73,
Rich VE3KI

Re: [Elecraft] Kx3 power output

[Bruce Beford]

Rich is absolutely right on this. Also, since the original question was
regarding the KX3, I expect the KX3 to behave the same way. Set the drive
level for the appropriate ALC meter response, and then set the output power
level where you want it.

Re: [Elecraft] Kx3 power output

[Don Wilhelm]

I would like to amplify what Rich is saying:
With the K2, or K3 and I assume also the KX3, set the desired power 
level with the power control and adjust the audio to fully drive the 
radio just to the point of onset of ALC.

The proper audio level is determined by the ALC meter.  With the K2, 
increase the audio until you see 1 ALC bar and then back off until it 
goes out.
With the K3 (and probably also the KX3) adjust for 4 ALC bars solid and 
the 5th bar flickering.
The first 4 bars of the K3 ALC meter are not actually an indication of 
ALC - they are more akin to a VU meter.  The onset of ALC is at the 5th bar.

If you attempt to operate the K2 or K3 (and likely the KX3) using the 
methods typically stated for other transceivers, they will "power hunt" 
trying to produce the power set on the Power knob, but will be 
"confused" because there is not enough audio to produce the requested 
amount of power.

I cannot emphasize this point enough - the way the K2 and K3 control 
power is different than that typically used by other transceivers.

Re: [Elecraft] Kx3 power output

[Joe Subich, W4TV]

> Set the drive level for the appropriate ALC meter response, and then

But remember that PSK31 has an approximately 3 dB crest factor (peak
to average ratio).  To prevent the K3 and presumably KX3 amplifiers
from saturating and generating a very wide signal, the maximum power
in PSK31 should be between 40 and 50% of the maximum available.  With
the K3 power control set for 40 to 50 watts, instantaneous PEP output
will be 100 to 110 W even though the typical PEP reading wattmeter may
only show 45 W.

[Elecraft] Raspberry_Pi...

[John Ragle]

I would be interested in chatting (off the reflector) with anyone who is 
also looking into the idea of using the Raspberry-Pi Model B for 
interaction with K3 or KX3. I do mostly CW and digital mode, and 
envision using the R_Pi only for the latter, possibly in a portable 
situation. I also use a PSK-20 and a Pennywhistle. For digital modes I 
use fldigi but imagine that DigiPan or Airlink Express would work if 
more limited capabilities were needed.

Re: [Elecraft] K3 feature request - auto-changing tuning rate

[Jim McDonald]

I would like that too.  I think either Icom or Ten-Tec that does that.

Icom does a good job on tuning rates, with a slow rate for CW and RTTY
(switch selectable) and a faster rate for SSB.

I change the K3's tuning rate for CW/RTTY to 1 kHz and back to 2 kHz for SSB
with the same with a macro in DXLab's Commander, but it would be nice for
the radio to do that automatically and speed up as Barry mentioned too.

[Elecraft] K3 Utility version 1.12.3.3 (Beta) for Terminal Page enthusiasts

[Dick Dievendorff]

I've received a number of requests related to the Terminal page for more
control over the "diddle" timeout period, and to turn on the transmitter
when a message memory is "played".

 

I've taken a stab at some revisions to the terminal page to try to meet
these requests without requiring everyone to change their behavior.

 

This is a "beta" version. If you have difficulty with it or want to roll
back to an earlier K3 Utility revision, uninstall the beta K3 Utility with
the Windows Control Panel Add/Remove applet before reinstalling the
"earlier" version.

 

Direct constructive feedback on these changes is solicited, to
d...@elecaft.com.

 

ftp://ftp.elecraft.com/tmp/K3/KUTIL/K3_Utility_Setup_1_12_3_3.exe

 

Configurable idle time out delay, and fonts.

Bracketed control strings embedded in Message Memories to control
transmission.

 

Details are in the revised Terminal Help page in K3 Utility Help.

 

Added Terminal page options dialog, with an "idle timeout milliseconds" text
box. 

 

RTTY/PSK31 "diddle" will stay on for that period after all characters have
been transmitted

unless you click the "Stop" button at the top of the dialog, or

press CTRL-T to toggle transmit to off, or 

press the ESC key, or 

have "played" a message memory with [TXOFF] in it.

 

Added special bracketed strings to message memories:

 

[CRLF] and [NL] are replaced by the RTTY or ASCII CR/LF or NL character.

 

[TXON] turns the transmitter on when the message is "played".

 

[TXOFF] overrides the "idle timeout delay", so that diddle is stopped when
the output buffer next becomes empty.

 

Some users have asked that the transmitter not be turned off immediately
after all characters have been sent. 

Some users have asked that the transmitter be turned on when a message
memory is "recalled" or "played".

Some users have asked that the transmitter be turned off immediately after
the message buffer empties.

Re: [Elecraft] K3 feature request - auto-changing tuning rate

[Don Wilhelm]

The K3 tuning rate is already selectable per mode.  See the Config menu 
for VFO CRS.

In addition, there are the FINE/COARSE and RATE buttons to help you with 
the tuning rate.

Please -- no dynamic tuning for me, it drives me crazy.

Re: [Elecraft] [KX3] noise blanker

[Wayne Burdick]

The KX3 has two noise blankers: one ahead of the narrow DSP filtering,  
and one after. Combinations of the two will be available to tackle  
different noise types.

The blanker ahead of the narrow filtering will behave similarly to the  
K3's IF blanker. Different settings will be available that  
automatically adjust the bandwidth of the roofing filter, if applicable.

[Elecraft] K3 feature request - auto-changing tuning rate

[DOUGLAS ZWIEBEL]

I'd never use it, but if it can be added and menu selectable (on/off),
what the heck...no skin off my back.

What I do, if want to make a big frequency excursion on the same
band/mode is simply use the "keypad" to enter the frequency in the
range I want to target.  But honestly, since I mostly use the rig for
contesting, I just keyboard in the QRG in the "callsign field" of my
logging program and bang...I'm there.

It's not the coarse rate that is an issue for me, although it would
certainly be nice for it to step up to 1 KHz if I really spun the
VFO.  What I'd prefer is ability to into fine if I'm tuning slowly,
particularly in data mode.

Tapping Fine every time I change modes drives me crazy.

[Elecraft] KX3 and KAT500

[Ron Gould]

Is there an update on when one could expect to get a KX3 if ordered now or 
Monday since Elecraft is currently closed?  Any word on when orders may be 
accepted for the KAT500 and its price?  Seems these dates have slipped a lot 
from what I last heard while at Dayton last May.  Seems I heard a tentative 
date of December for KX3 and September/October for the KAT500.  I wonder if 
Kenwood, Yaesu, Icom, or Ten Tec have tentative delivery dates for any of their 
products like this, not that I'm getting ready to order from them?

Re: [Elecraft] KX3 and KAT500

[Bruce Beford]

Ron-
Based on statements made at the latest hamfests, and on there being probably
WELL OVER 1000 people ahead of you who have already ordered- I think if you
ordered today you could be looking at 3 months before you see your KX3.

As for the KAT500, latest word was another PC board remake to reduce stray
capacitances, and field trials in the next few weeks. Could be a similar
wait to the KX3 for production shipments to begin. I am sure there is a lot
of pent-up demand for the KAT500 as well- expect that queue to fill quickly
once orders are taken.

Re: [Elecraft] KX3 and KAT500

[Keith Heimbold]

When I spoke to Eric at the Yuma hamfest two weeks ago today, I asked if my KX3 
would be in my hands for my wife's and my babymoon to Aruba next month around 
the 6th of April. He said not likely.  

I ordered mine on New Year's day from what I recall.  Took me a couple days 
after it was made available for order  to decide if I wanted barebones or fully 
loaded KX3.  I ended up getting a loaded one. I am so excited and am also 
wondering when that bad boy will grace my presence.

[Elecraft] K3: Audio Level Ramp-Up in DATA-A

[Edward R. Cole]

I'm wondering if there is a way to escape the 4-5 second gradual 
increase (ramp up) of audio drive when in DATA-A mode on the K3?  I 
run WSJT on DATA-A and every transmit sequence starts at about 50% 
power out due to the audio drive ramp up.  It takes the K3 about 4-5 
seconds to reach full power.  This OK when my transmit sequence is 1 
minute long but there is a test mode under WSJT called Echo which 
permits me to measure my own eme echoes.  However, Tx/Rx cycle in 
Echo is about 1.5 seconds long and I cannot test at full power.  This 
is a fully automated test routine so I can't use CW.  The program 
transmits a continuous tone which is the same as key-down on CW, and 
returns a measurement of my Moon echo which is real nice to determine 
system performance.

But I can't use the Echo function with DATA-A on the K3 as it is.  I 
wonder why the K3 acts this way in DATA-A?  I did not have any issue 
running WSJT test modes with my FT-847.

Re: [Elecraft] K3: Audio Level Ramp-Up in DATA-A

[iain macdonnell - N6ML]

Hi Ed,

1) Make sure you have 4-5 bars on the ALC meter when transmitting your
JT65 signal - insufficient audio drive could lead to the DSP
compensating by adding gain

2) Run through the TX gain calibration (see K3 Owner's Manual)

Re: [Elecraft] K3: Audio Level Ramp-Up in DATA-A

[Don Wilhelm]

Ed,

Are you driving the audio to give you 4 bars solid and the 5th blinking 
on the ALC meter?
The behavior you are seeing is normal if you do not have enough audio.

The lower 4 bars of the ALC meter do not indicate ALC, they are similar 
to a VU meter.
The 5th bar indicates the onset of ALC.

[Elecraft] Elecraft SSB net announcement

[Phillip Shepard]

The weekly Elecraft SSB net will meet tomorrow (3/4/12) at 1800Z on 14.3035
MHz +/- QRM. I will be net control from western Oregon, and we'll try relays
to pull in the stations that I can't hear.

See you there.

[Elecraft] 7261 finished all is well except?

[Don Baucom]

I finished last night. The receiver/transmit alignmet went well ( I used the
XG3) I had one QSO last night.
He gave me a 599 but said something about freq. I did not catch it.. I have
been calling and answering Cqs with no luck today. So I took the antenna of
my FT-950 and cranked the power on the K2 down to 1 watt. My 950 has a bar
graph that centers on the correct CW spot. When I send on 7035.00. The 950
says I am on 7035.50.  The Pitch was set on 500 . The only time I thought a
guy came back to me when I answered his CQ he also said something about
Freq?

Have I got something out of wack or am I just having a rough day with 12
watts?

Re: [Elecraft] 7261 finished all is well except?

[Don Wilhelm]

Don,

It sounds like you have the CW filters set for the wrong sideband.  The 
CW (non-reversed) filters must be lower sideband while the CWr filters 
must be set for upper sideband.  What that means in terms of BFO 
frequencies is that the CW filters will be in the vicinity of 4913.6 to 
4913.0 and the CWr BFOs will range from 4915.3 down to 4914.2.

For good dial calibration, once you get your CW sidebands correct, go to 
my website www.w3fpr.com and look at the article on K2 Dial Calibration. 
- it deal with both dial calibration and filter alignment.

Don W3FPR

Re: [Elecraft] Call for Elecraft CW Net volunteers

[Geoffrey Mackenzie-Kennedy]

Hello Kevin,

Sorry to hear that your new antenna has been felled by trees.  If of any
interest to you I can send you a sketch of a "Counterweight Fuse"
arrangement which I used in Scotland to prevent any of my wire (Flexweave)
antennas being broken should a tree fall across an antenna or its catenary -
which did happen on more than one occasion during gales (tall pines).

If a tree falls across the antenna/ catenary the "Fuse" will "blow", which
allows the antenna/ catenary to fall under the tree without breaking. Remove
the tree and reel in the hoist rope, and you are back in business.

73,

Hi Rich,

A very thoughtful response.  PSK31 is one of my favourite modes.  I 
have used several different xcvrs ... at the moment I am using a 
Kenwood TS-50 and I have setup another xcvr (an old Ten Tec) as a 
monitor.  As you point out  the signal must be kept below S9 in the 
monitor rcvr in order to get an accurate read on the IMD of the 
transmitted signal.  I did the tests into a dummy load.  The TS-50 is 
primarily designed as a mobile SSB xcvr ... however I find it 
provides excellent IMD (in the -30db area) when I set it for full 
power and set the PSK31 audio level that produces 15 watts RF 
output.  Beyond the level the IMD figures drop rapidly.  I generally 
operate in the 10-15 Watt output level and I seem to be able to work 
anyone I hear ... including a lot of DX (with my rotatable dipole at 
16M height).

I expect the KX3 will work vy well at 5 watts output.  When the KXPA3 
comes out I would expect to be able to generate a clean signal in 
that 15-20 watt range..

Hi Bruce,

I expect you are correct ... a different method of setting the 
output.  The strategy described by chip is the method I use with my 
old Kenwood TS-50.  But since the TS-50 has no ALC indication I used 
the monitoring method to determine the amount of drive that initiates 
a drop in IMD.  The TS-50 is rated at 100W PEP output on SSB ... 
however careful monitoring indicates the IMD drops dramatically 
beyond 15W output!   I operate between 10 and 15 watts and get great 
reports.  I will have to get used to KX3 method of controlling power output.

[Elecraft] K2 MH2 P1 jumper wiring w/5.6k resistor

[Gene N4FZ]

I just bought a used K2 that needs to be wired for the Elecraft MH2 mic.
Question: Do ALL the jumpers have to be soldered directly across, as per
instructions with the mic? The P1 strip looks different, (has exposed long
pins, that have pins 1, 2, 7, 8 jumpered and soldered), than the 2008
instruction sheet. It looks like pins 3,4,5 are unused. Any help is very
much appreciated! Gene

Re: [Elecraft] K2 MH2 P1 jumper wiring w/5.6k resistor

[Don Wilhelm]

Gene,

It is not clear, so I am going to make an assumption (you know what that 
means) that pins 1. 2, 7 and 8 are jumpered straight across the mic 
configuration header - AF to pin 1, PTT to pin 2, GND to pin 7 and GND 
to pin 8.  If that is true, all you need to add is a jumper from 5V to 
pin 6 AND a 5.5k resistor between pins 6 and 1 on the back of the 
microphone jack.

Yes, there are other pins that could be connected - UP, DN, FUNC, but 
there are no corresponding buttons on the MH2, so don;t bother 
connecting them.

The relevant information is in the KSB2 manual which you can download 
from the Elecraft website.  If you do not have the paper manuals, I 
suggest that you download the manual for the K2 and the instructions for 
all your installed options.  Read through the alignment and operational 
parts of each of them to familiarize yourself with your new K2.

Re: [Elecraft] K2 MH2 P1 jumper wiring w/5.6k resistor

[Don Wilhelm]

Gene,

In that case, if there is a 5.6k resistor soldered between pin 6 and pin 
1 on the back of the mic jack, you are all set to use the Elecraft MH2 
microphone.  If the resistor is missing, I would assume the prior owner 
was using a Kenwood microphone or a Heil microphone with a Kenwood 
adapter.  The most you should have to do is add a 5.6k resistor between 
mic jack pin 6 and pin 1.

Sorry, "fat fingers" - the resistor value is 5.6k.  You would have a

Re: [Elecraft] K3 feature request - auto-changing tuning rate

[FredJensen]

If it's selectable and I can turn it off, fine.  My FT-847 does this and 
I hate it.  K3 works just fine for me, however I get only one vote.

[Elecraft] Elecraft CW Net Announcement

[kevinr]

Good Evening,
 There will be a net tomorrow but I will not be the net control.  
Even though I have found most of my latest antenna it may not be 
repaired in time.  So there will be at least one net control if not two 
of them.  If I get my antenna back up I will check in but the nets will 
be under guest control this week.

Please join us tomorrow afternoon and evening.

1) Hail signs  (first letter or two of the suffix of your call)
2) NCS help  (as well as QSP/QNP  help)

Sunday 2300z (Sunday 3 PM PST) 14050 kHz
Monday 0100z (Sunday 5 PM PST)  7045 kHz

   Stay well,
  Kevin.  KD5ONS

Re: [Elecraft] - tuning rate

[Jack Berry]

Kenwood 850 had a good solution - a second, small fast tune knob that could 
selectively tune 1 or 10 kHz. Not possible for the K3 but can maybe be on a 
'K4' wish list. 
It's the only 850 feature that I really miss.

Re: [Elecraft] - tuning rate

[Rick Prather]

I wonder how many ops that want a selectable faster tuning rate have VFO OFS 
set to ON?

>From the manual:

"VFO OFS

If ON , the RIT/XIT offset control can be used to tune VFO A in large steps 
when both RIT and XIT are turned off. The step sizes vary with mode (see VFO 
CRS), and are the same as the Coarse VFO tuning rates."


I use the RIT control in this way for large excursions and find it very useful.

Re: [Elecraft] - tuning rate

[Don Wilhelm]

Guys,

Read the K3 manual  (especially the menu entries)- it is already 
"included" in the package.
Set the menu VFO CRS to whatever you desire (note that it is per mode).  
Then set VFO OFS to ON and you can use the RIT knob to tune in the VFO 
Coarse steps.  Yes, it does not work if RIT or XIT is turned on, but 
works FB when they are off.
