[Elecraft] NAQCC Sprint Announcement

[Larry Makoski W2LJ]

The NAQCC QRP CW Sprint for March is this coming Wednesday night March 
15th (Thursday morning, March 16th UTC time).  This month, there will be 
two time periods open for the contest to benefit Amateurs on the West 
coast.  The available time periods are 8:30 to 10.30 PM EST or 8:30 to 
10:30 PST (0130 to 0330 and 0430 to 0630 UTC).  You may operate both 
time periods; but you may only submit a log for ONE time period.


This month's Sprint will be held on 80 Meters ONLY. The suggested 
starting point for participants is from 3.555 MHz to 3.565 MHz and there 
abouts.  Please be considerate of non-contesting FISTS members who 
congregate around 3.558 MHz !!!


Those who wish to initiate calls, please use "CQ NA".

The exchange is RST - SPC - NAQCC Member Nr.  (for those who wish to 
participate that are not NAQCC members, simply substitute the member 
number with your output power.  Please use a "W" to indicate that you 
are sending a power output figure!


A bonus is awarded as follows:

If you use only a straight key for the entire sprint, multiply your 
score by 2.

If you use only a bug for the entire sprint, multiply your score by 1.5.
If you use a keyer, keyboard, or computer, there is no bonus multiplier

ALL amateurs may participate; but only those using QRP power levels may 
compete for awards.


For details - please check: http://www.arm-tek.net/~yoel/sprint200603.html
To join the NAQCC please check: http://www.arm-tek.net/~yoel/joinup.html

This month the contestant who earns the highest numeric total of SKCC 
member numbers will earn a special certificate.

The battery switch only disconnects the battery. It has no impact on 
supplying power to the radio.





With an old (4+ years) battery installed, and plugged into external 
power,
what would be the nominal reading off the K2's internal voltage meter? 
On my

radio #309, I only show about 12V, power supply is providing 13.8.


If the voltage on the K2's display reads 12 V even with the battery 
switch OFF, then either the K2's voltage monitoring circuit is in 
error, or your external DMM is.


If the voltage on the K2's display goes up to about 13.3 V or so with 
the battery switch OFF, but is 12 V with the battery switch ON, the 
battery is trying very hard to take a charge. If it gradually increases 
to 13.3 V or so over about an hour, the battery may be OK. But if it 
just sits at 12 V all the time, your battery may be unable to charge. 
In this case it should be replaced.

[Elecraft] Elecraft CW Net Errata

[Kevin Rock]

One error this week.  I copied the call just fine.  But then I transposed 
two characters and then cut and pasted it so the same errors shows up 
twice.  Maybe that should be counted as two errors ;)  But I wanted to get 
to soldering and did not go over the lists again for accuracy.  I did 
study the punctuation however.


The error?
K5TE - Jay - CO - KX1 - 969

Should really read:
KT5E - Jay - CO - KX1 - 969

Close, but not close enough.

Just before I went to bed I ran through my rough notes from EQP.  I made 
more contacts than I thought!  I had fun too.  Maybe next year I will try 
to spend more time at it and work more than three bands.


Sorry for the break in the daily Elecraft news.
   Kevin.  KD5ONS

P.S.  Ask Jay what he uses for an antenna and feedline.  I think you will 
be surprised.

[Elecraft] Off top post Re:FT1000mp

[vk2nu]

Apologies for the off topic post, but thought someone on the reflector with 
more technical savvy than me could point me in the right direction. I've tried 
the FT1000mp reflector, but was no help.

My FT1000mp failed on me at the weekend, that 18 and 21mHz bands have gone deaf 
and I have no output power. The problem is sporadic, and the rig seems Ok, when 
I turn it on cold, but after 20-30 minutes I lose these bands. The radio goes 
deaf (+no tx pwr) between 14.500 and 21.999, and these frequencies correspond 
to a band change relay clicking in, so I assume there is maybe a fault with 
either a relay or possibly something in the LPF network corresponding to this 
frequency range.

I'm looking at putting it into a shop for repair, but if it is simply a matter 
of replacing a relay etc, I'd prefer to have a go myself.

If anyone is familiar with the radio, and has some ideas, please e-mail off 
reflector..

"To get back on topic, I had a listen in the EQP at the weekend between 
operation in the Commonwealth Contest. The only station heard was KD5OMS (from 
memory), calling on 40m, but he had stopped by the time I had connected up the 
K2"

Regards all and apologies again for the off topic post

Re: [Elecraft] K2 microphone question

[John R. Lonigro]

Werner:
I went to the ICOM website and did a search on the SM-8 microphone. I 
found the IC-718 uses the same mic, so I suggest you download the manual 
for the IC-718 and you should find enough info about the microphone and 
the connector to get it working on your K2. I don't think there's a 
circuit diagram for it, but there is a pin-out for the connector on the 
radio and you can figure it out from there. You can do the same for 
other mics you may be interested in interfacing with the K2.


73's and good luck,

John AA0VE

[Elecraft] Polar Bear Pics Needed!

[Edward R. Breneiser]

Hello all,

I'm putting together a polar bear Power point presentation and need some
PB pics from the following bears: VE3WMB, W9HZC, N5SEZ, N0TU and VE3WEH.
If any of these bears have some pics, please email them to me to include
in the Power Point Presentation. I would really like a mug shot of you
too. It's shaping up to be a nice presentation! Once it's finished, I
plan to show it at Atlanticon for general viewing.

To all the other bears out there. If you want your favorite picture in
the presentation, please email it to me. I will make the presentation
available after Atlanticon or around April. If you already gave a
donation to the EPA QRP Club for the "Polar Bears Gone Wild DVD," the
Power Point Presentation will be included on that disk.

To all those who haven't heard about the DVD, click on the link below
for information.

Re: [Elecraft] KX1 s/n 1287 now a four-bander

[David Toepfer]

I have not done this yet (though I plan to), but I'll take this time to suggest
the Hakko 808 desoldering gun ().  I
bought mine a year or two ago and OMG, it is wonderful.  I spent years when I
was younger fiddling with desoldering braids and ruining PC boards.  This thing
is just wonderful.  Money well spent.

[Elecraft] Delaware Water Gap Hike/Radio Trip: April 15-16

[Edward R. Breneiser]

Hello all!

Look for N7UN, WA3WSJ and maybe NU3E to hike the DWG and play radio.
We plan to start the hike on the AT near the Delaware River at the NJ
line. From there we will hike into the DWG also known as  Worthington
State Forest. We will climb the AT some 900' and camp some three miles
into the Kittatinny Mountains at a campsite with a view. We should end
up at an elevation just over 1300' overlooking the Delaware River. On
our way to the campsite we will hike along Dunnfield Creek with
waterfalls etc. I will also hike the extra mile or so and visit Sunfish
Pond as I would like to see it too. Talk about a scenic trip! So look
for us playing radio and having fun April 15-16. As usual look for us
near the qrp frequencies. I ,hopefully, will have my 4-band board in my
K1 by then - hi!

72,
Ed, WA3WSJ

[Elecraft] Kx1 3080

[Ed K1EP]

I guess I will wait until Dayton to view the new 80M module for the KX1.  But I 
have to ask, if it hasn't been asked already...what about 160M?  Operating 160M 
QRP is, well, not easy.  But I think that the KX1 would be interesting on 160M. 
 I guess I might wait for the 1608030 module...

Although I purchased a 30m kit at the time I got the KX1 and KXAT1, I never did 
get around to installing it.  However, if you are concerned about desoldering, 
you should know that the new 80 & 30 meter kit does require desoldering a few 
components from the KX1 board, in addition to removing the existing 30m kit.  
(Only one of the removed parts gets re-used and in this case Elecraft supplies 
a spare in case you destroy it).  The desoldering is not difficult, but does 
require some care.  Elecraft recommends using a good vacuum desoldering tool.  
I got by using some very small (0.1" wide) solder wick; however this is risky.

[Elecraft] PTT Signal Question

[Kevin Shaw]

I'm in the process of designing a USB interface board for my K2 and I have a
technical question concerning the "/DOT-PTT" signal in the K2. The signal
goes into Port D of the PIC processor. PTT is grounded when the microphone
is keyed yet I don't see a pull-up resistor on the signal. I believe Port B
of the PIC has internal pull-ups but not Port D. Is there a pull-up on that
signal somewhere on the schematic that I'm missing?

 

Thanks,

 

Kevin

Re: [Elecraft] K2 SPLIT AND DX CLUSTER SPOTS WITH LOGGER 32 & N1MM

[Rich McCabe]

So sniff it!

If you don't have a network sniffer (most don't), you can use another PC 
(or
laptop). Configure Hyperterm to look like a K2, hook up the cable, and 
tell

the logger to do the spot. The "commands" will appear on the screen!


PortMon does the same thing without using another PC. Just start it before 
you start your serial application and watch the data. And its free !

Re: [Elecraft] KX1 signals peak at low audio beat frequency

[Martin Gillen]

Hi, Mike.

I noticed exactly the same thing here.  In fact the
passband ripple of my KX1 is pretty bad, 600Hz is
actually in a trough not a peak!  And when I narrow
the filter to the narrowest setting it centers on
around 480Hz.

Neither of these is a fairly significant issue in
practice though.  If I have occasion to use the filter
in its narrowest position then I zero beat first then
use the RIT to move the signal down to 500Hz before
closing the filter to its narrowest position.

Most of the time my filter stays in one of three
positions:

5 oclock - fully open - Quiet band.

12 oclock - halfway open - Fair amount of QRM.

9 oclock - about 2/10 open - In the 9 oclock
position the audio peaks (to the ear) at 600Hz
so this is the most useful position for zero-
beating.

I almost never close it right down (7 oclock position)
however I did last weekend when I had a station come
on 100Hz away from my QSO and he couldn't hear me.

In this situation I use the RIT control to send the
wanted signal to 500Hz after zero-beating at 600Hz.

Does that help?

By the way Michael VE3WMB mentioned before that he
has the same ripple pattern in the ten-tec scout
and it may be a feature of the Jones filter design.

After all the component count in the KX1 is tightly
controlled and there are tradeoffs because of that.

RE: [Elecraft] K2 SPLIT AND DX CLUSTER SPOTS WITH LOGGER 32 & N1MM

[Dan Barker]

So sniff it!

If you don't have a network sniffer (most don't), you can use another PC (or
laptop). Configure Hyperterm to look like a K2, hook up the cable, and tell
the logger to do the spot. The "commands" will appear on the screen!

If the software won't do the spot without first communicating with the K2,
you may need to rig a splitter for pins 5 and 3 (sig gnd and TxD FROM the
logger), but don't split out pin 2, it will just confuse the issue.

btw, documentation or the vendor's input is a better choice - OR - write
your own macros, then you'll know what they do and can make them do what you
want.

You Still haven't said what you WANT the macro to do. I'm just guessing what
is desired.

Dan / WG4S / K2 #2456


N1MM does not have a Radio Debug window like Logger 32 and so I am
unable to see what the actual command that is sent by N1MM to the K2.

RE: [Elecraft] K2 SPLIT AND DX CLUSTER SPOTS WITH LOGGER 32 & N1MM

[Chris Page]

Thanks to Don, Dan and Rich for their explanations of this problem.

Whilst noting what Don says about Logger 32 not sending the TX and RX 
information for each of the K2's VFOs, and that being the reason it 
will not work effectively, it cannot be the reason why it won't work 
with N1MM.  N1MM does send the TX and RX frequency information for 
each VFO, at least whenever the spot on the DX Cluster contains a TX 
and RX frequency, ie split operation on 40 and 80 metres CW.

N1MM does not have a Radio Debug window like Logger 32 and so I am 
unable to see what the actual command that is sent by N1MM to the K2.

By the way Rich, what logging program are you using?  It will be nice 
to know of one that doesn't cancel the split option on the K2.

Re: [Elecraft] K2 SPLIT AND DX CLUSTER SPOTS WITH LOGGER 32 & N1MM

[Rich McCabe]

I would say you have a software issue and not a hardware one. I have no 
problems setting splits on the K2.


If the command you listed is the one for split it will not function. They 
are not doing the FB so its useless.


K2 has a split button emulation "SW26" but  appears they are not using this.

I am not familiar with your logger program and although its possible to use 
software to do the splits, they are not getting it done without  setting the 
VFO B.

Thanks for your quick reply Dan.

Logger 32 has a "Radio Debug Window" which shows the commands and
replies going between Logger 32 and the K2.

When I click on a DX spot, Logger 32 sends the following message to
the K2:

Set Radio Freq/Mode : FR0;FA0001808;MD3;FA0001808;

Re: [Elecraft] Filter alignment question

[Don Brown]

Hi

Here is a way to check the alignment of the filters. Assuming a 600 Hz 
sidetone tune to 4.000 MHz in CW normal mode You should hear the 4 MHz 
internal oscillator as a 600 Hz tone, Switch to each filter and the tone 
should not change frequency by more than a few hertz. Then switch to CW 
reverse and go back through the filters. Again the 600 Hz tone should not 
change. To check the SSB filters select LSB and tune to 4.00060. You should 
hear the same 600 hertz tone then check each SSB filter and the tone should 
not change. Now change to USB and tune to 3.99940 MHz and check for the 600 
hertz tone on each filter. If you do not hear the correct tone on any of the 
above tests then you need to recheck the filter alignment for that filter. 
You may have it set on the wrong side of the filter slope or may need to 
move it slightly. Use spectrogram to re-align the filters after first 
setting them to the values listed in the manual so they are in the ballpark. 
You should move each filters BFO frequency slightly even if it is correct so 
the firmware will recalculate the sidetone offsets.

The short answer is   yes and nothing!
Yes it is the norm and nothing can be done. 

Then the longer answer  That's how Logger 32 works.  It will not 
send split
frequencies to the DX Cluster nor will it recognize them from the 
cluster.  The
ham who writes Logger 32 does not believe in split operating.  Every 
time the split
subject comes up on the reflector for Logger 32 it results in a 
sometimes long,

sometimes volatile, thread  happens on most reflectors, doesn't it?

Logger 32 is a fully featured program with more stuff than I use - the 
price right and

it does have a few things that are whims, or beliefs of the software writer.

[Dan Barker]

Set Radio Freq/Mode : FR0;FA0001808;MD3;FA0001808;


Let's see what that is SUPPOSED to do (ref: KIO2_Pgmrs_Ref_revC)

FR0;
 Sets receive VFO to A (What about transmit? Don't you need an "FT1;"?

FA0001808;
 Set VFO A frequency (What about VFO B?)

MD3;
 Set Operating Mode to CW

FA0001808;
 Set VFO A frequency again (interesting - maybe the MD3; sometimes resets
the VFO? - Then, why the first FA?)


Anyhow, to rule out a firmware glitch, you should do the above commands
manually, and with Hyperterm, and see if they perform differently. They
shouldn't.

I powered up my K2 (first time since we moved, last Saturday) and it's
busted. Probably mechanical, but I don't have time to look now. Poweron I
get a horrible buzzing in the speaker, regardless of the AF pot setting. I
immediately unplug. Will inspect before debugging. However, you may want to
try those commands yourself.

You need macros that accurately reflect what you want to do. BTW, I'm not
sure what you expect it to do. When you click on a spot, should it set two
frequenies? Should it set one and set the other some fixed offset from it?
Should it read the current offset and apply that to the freq in the spot?

I agree "it" shouldn't change the SPLIT/NOR mode. ("it", in this case -
Sorry Mr. Clinton - means the software/K2 Combination).

RE: [Elecraft] K2 SPLIT AND DX CLUSTER SPOTS WITH LOGGER 32 & N1MM

[Don Wilhelm]

Chris,

The K2 is operating properly - apparently Logger 32 programmers wanted Split
to be cancelled or they would not have sent that string of commands.
The KIO2 Programmers Reference clearly indicates that the 'FR' command
always cancels Split mode.

To work effectively with a program in Split mode, the program must be aware
of which VFO you are using for transmit and which for receive.  My guess is
that Logger 32 did not want to deal with that potential for confusion
because the transmit VFO can be quickly changed by a tap of the front panel
button or by a KIO2 command - many things could easily get mixed up.

RE: [Elecraft] Filter alignment question

[Don Wilhelm]

Mike,

Which oscillator are you referring to as "local Oscillator"?  If you are
referring to the BFO, then it should be different from LSB to USB because
that is the way the sidebands are switched.

If you are referring to the VCO, then you must be retuning if that changes
between LSB and USB - if there is a need to re-tune to maintain zero beat,
then yes, a filter alignment is in order, and perhpas a dial calibration
also.  Full, detailed instructions for setting the reference oscillator and
doing a dial calibration and filter alignment can be found on my website
http://w3fpr.qrpradio.com

[Elecraft] Filter alignment question

[info4mjs]

Hi, 

I was monitoring the K2's local oscillator frequency and I noticed that as I 
tune to WWV in the various modes, that the LO frequency is different at zero 
beat.  I expected an offset (w/respect to SSB) in the CW mode but I expected 
the LO to be the same at zero beat whether I was in LSB or USB modes.  It isn't 
so I am wondering if something is not aligned properly.

Any insight is appreciated.

[Elecraft] K2 microphone question

[Dr. Werner Furlan]

I am going to finishing the SSB board (with the QRP-Project modification 
included) in some days, as soon as the parts I need arrived. 
I have several microphones I could use, so maybe you can give me some 
advice. 
I have one Icom SM-8 microphone - is there a circuit diagram around for this 
type of microphone? I read in the manual of the K2 that some information for 
microphone jumpering should be on the Elecraft website, but I did not find it 
yet. 
Then I have a Kenwood hand microphone (from a VHF SSB transceiver), 
and a Heil Pro Headset. 
I have also read about the good idea to make a plug for each type of 
microphone from discarded IDE plugs. (several around here)
Maybe there is a list of microphones with my SM-8 type listed?

RE: [Elecraft] K2 SPLIT AND DX CLUSTER SPOTS WITH LOGGER 32 & N1MM

What commands do these programs send to the K2 when you "click on a spot"?
That is the first question. If the documentation doesn't say, and the vendor

[Elecraft] K2 SPLIT AND DX CLUSTER SPOTS WITH LOGGER 32 & N1MM

[Chris Page]

For general day to day operating, I normally use the K2 in SPLIT mode 
(with the flashing V over A on the front panel) and have the 
Secondary Menu option set to PER.

I use Logger 32 connected to the DX Cluster through the Internet and 
have noticed that when I click onto a Cluster spot, the K2 correctly 
goes to the frequency and mode of the spot, but the SPLIT option is 
cancelled and the K2 returns to its default setting of no SPLIT.  
This happens whether the Secondary Menu SPLT option is set to NOR or 
PER.

Is this the norm, and if so is anyone aware of a mod that can be done 
to prevent it happening, please?

It is especially annoying when a DX station working split is spotted 
on the Cluster.  The K2 is correctly sent to the DX station's 
transmitting frequency, and after using the A/B button to find the DX 
station's listening frequency, I transmit only to find I am 
transmitting on the DX station's transmitting frequency because the 
SPLIT option has been cancelled and I have forgotten to switch it 
back on again.

Of course, this can be got round by hitting the SPLIT button after 
clicking on the spot, but in the heat of the chase for the DX 
station, I often forget to do this.  In any case, in a well designed 
radio (like the K2) it should not be necessary to have to remember to 
do this.

Although I don't use the K2's RIT option, the same thing happens with 
that, it is cancelled when you click on to a Cluster spot.

I use N1MM Logger for contesting and the same thing happens when you 
click on a DX station in that program.  The problem must therefore be 
with the design of the K2 and not the logging program.

I searched the Elecraft Reflector Archives for an answer and found 
that WA2DGD asked the same question in July 2001.  Larry was using 
the DX4WIN logging program and the answer provided was to use the 
TS850-TS950 option in DX4WIN for setting the radio, but Logger 32 
only has a KENWOOD ALL option, which is the only one that works with 
the K2, and N1MM Logger specifically has an Elecraft setting.

Thanks for any help.
