I can't imagine that you would have any problem with just plugging
the KUSB into the USB port on the PC with Win7 and let it find the
driver.  I don't have a KUSB, but I use FTDI USB to Serial cables and
have not had a problem with Win7 finding the proper driver for them.

Win7 found everything it needed to use any of the popular logging
programs with USB to Serial cables for the K2, K3 and WinkeyerUSB.

Re: [Elecraft] K2 Firmware change request

I used my pair of K2/100's in last weekend's NAQP CW. Band conditions were
pretty good for August, and I ended up with 789 qso's. I use the pair
SO2R, meaning I am listening on one band while transmitting simultaneously
on another band.  In the NAQP mults count on every band (including 160),
and you change bands a lot.

I was reminded again of a K2 firmware "bug" that has been very annoying to
me: after changing bands, the K2 transmit power is reset to zero. I takes
several dits for the power to come up to 100%. That means if I change
bands, the first station I call gets something like "AOGW" instead of
N4OGW! If I forgot to hit the tune button or send a string of random dits,
the station I was calling frequently came back with "?" I'd rather not
have to QRM other stations "tuning up" every time I change bands.

Is it possible to make the K2 start out at 100% TX power? Is this supposed
to protect the finals?

In the NA Sprint contest (coming up in September!) this is a really big
deal. There, you must QSY after calling CQ, and if the station I am
calling misses my call, I may never hear him again!

I'd say if you are going portable a lot, a switching power supply.
If you are going to stay home and never roam, a traditional heavy power

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

[Hank Kohl K8DD]

Chris Page wrote:
For general day to day operating, I normally use the K2 in SPLIT mode

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?


Chris 

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.

Re: [Elecraft] Microphone for K2

[Hank Kohl K8DD]

Sara 

The Kenwood MC-43S is a good microphone, however you said "for Contests 
/ Dxpeditions".
It is very difficult to either keep a log sheet with pen or pencil, or 
to type on the keyboard
and picking up the microphone on every QSO. 

I would recommend one of the Heil Prosets, and the Heil foot switch to 
give you hands-
free operation and make it easy to log the QSO's while you are talking.  
We have used
them with the K2 on several DX trips to FP, V47, etc and they have 
preformed very well
with the K2 (and other radios).  My favorite with the K2 is the Heil 
Proset IC with the

Heil Icom adapter, and the K2 microphone header set up for Icom.

The K2/100 can handle the voltage/current requirements . But he 
relay in the Ameritron amps is not the fastest relay to pick  --  it 
takes at least  50ms or more. 
During that time the K2/100 sees a high SWR during this time and shuts 
down the amp, so you start sending and the amp has no output - and you 
never know if you aren't watching the meters.  K6XX has a "relay 
accelerator" circuit on his web site that works great in speeding up the 
relay - my AL-1200 with this circuit built on a terminal strip has not 
failed since I put it in place.
Doesn't happen with other radios and the Ameritron amps  Just the

Take a look at http://www.kkn.net/~k5tr/trlog/switch.pdf
This is a schematic that I have used to switch between two K2's. 
I do not operate that much SSB, so I did not include the relay to switch 
the microphone,
but the logging programs that I use (CT, Logger32) switch the keying and 
amp T/R line using

Pin 14 on the LPT port.
You could also do it with a manual switch.

Re: [Elecraft] Which logging software

[Hank Kohl K8DD]

What a question to get some emotional answers!   :-) 
Logging programs are like wives . find a good one and stick with it!


My choices would be:
For general logging - Logger32 - very full featured for awards and all 
the features of the $100
class programs . For Free and a real good support mailing list.  
www.kc4elo.com


For contesting -
DOS NA Logging Program.  It covers QRP-ARCI format contests.  But 
it's not free.

WindowsCTwin Logging Program.  Freewarewww.k1ea.com

AGC - was [Elecraft] OT-Preserving CW memories

[Hank Kohl K8DD]

I was at VO2AAA in Labrador City for CQ WW CW with K2/100 #850 and an 
AL-1200.  We were next to a residential area with a very high line noise 
and precipitation static.
On 80 and 160 meters with the AF gain about 3/4 way up and riding the RF 
gain and DSP with noise reduction made some of the second & third tier 
stations copyable.   Sometimes you have to be really fast on reducing the 
RF gain to save your ears!


I don't really like the "sound" that I get out of my K2 with the DSP, but 
when you are digging stations out of the noise the NR and the DSP filter #1 
really helped.


The K2 as the run station was good for about 3000 Q's, the mult station for 
a couple hundred.  And 3.4M points.  Think I remember working a couple 
calls from this list!

Ron and all,

Are you aware that reducing the RF gain will reduce the AGC action as 
well. Folks who want to try it may be surprised how well copy can be made 
under QRM conditions with the AF gain at full and the overall gain 
controlled by the RF gain.


With this technique, the residual AGC provides some 'limiting' protection 
for the ears while allowing one to dig for really weak signals - this is 
applicable at any bandwidth, but more so for wider ones.

- Original Message -
To this day I still prefer a wide filter, even with moderate QRM. With my K2
on CW, I use the SSB filter more than any other.  I love being able to keep
track of what's going on around the frequency I'm using. The trick of
course, is to turn off the AGC so stronger signals in the passband won't
depress the receiver gain. One of these days I'll add a hard limiter to
protect my ears. The dynamic range of the K2 allows really huge peaks to
come through without the AGC.

Re: [Elecraft] G5RV advice...

Actually I think the ones that I've made are pretty darn good.
And much more economical - find 102' of wire, a couple of short
pieces of 1/2" PVC for the insulators, 28' 300 ohm twin lead
from Radio Shack -or where ever - and some coax.  And some good
black tape! 
The dimensions are from http://www.g3ycc.karoo.net/g5rv.htm

and work pretty darn well!

I've seen G5RV kits for around $33 from the Wireman. He even
throws in 100 ft of rope.  The Wireman has good stuff if you
can't find all the parts in your shack or in any of the local
hams shacks!

That's not entirely true  at least in my case.  In a contest about

RIT for the stations that don't

When I'm searching, it's the main tuning knob and maybe the AF gain.
The computer control keys the radio, keeps track of the frequency/band.
I try not to use any more of the buttons on the front panel than I have 
to when I'm contesting.


Pretty much the same for DXing  Set the filters the way I want them

Or   it's not a Johnson TR switch and separates.  Or  it's not a 
Ten Tec.   But the K2 has enough features to make up for not having QSK.

Can you hear the receiver between dits on the cw transmit when using QSK? I

perform at least as well as the TS-850 (now sold as seed money for the K2)

Re: [Elecraft] KNB2 (or any NB) performance

[Hank Kohl K8DD]

From sitting at my desk with 2 K2/100's and an IC-746  and an 
IC-706MKiiG in the truck .

It seems that noise blankers in general .
Work sometimes
Don't work sometimes
degrade signal quality sometimes
don't degrade signal quality sometimes
Coupled with (or without) a combination of pre-amps, attenuators, DSP 
noise reduction and / or the DSP filters .. You could even add one 
of those noise reduction boxes that use a sense antenna. 
You might get rid of the noise.  Or  you might not!


The KNB2 works real well for a $40 noise blanker.  How many would be 
willing to pay several hundred dollars for the noise blanker that I'd 
bet Wayne could have designed?


But it's just like paddles, cars, wives and cold drinks . one 
size/type/model doesn't fit all.  I could say "use what works", but that 
may not be politically correct in this case - so I didn't!

I have found that messing with the pre-amp and attenuator sometimes 
gets it to work.


Also, I can only remember a few times when high or low threshold made 
a difference and only once where NB1 vs. NB2 made a difference.


The NB2 is adequate most of the time.  I built my K2 to have one of 
the very best receivers available, regardless of price.  For low power 
draw and portability, the K1 and KX1 fit the bill nicely.  But, the 
prime draw of the K2 is it's top performance.


It would be great if the NB2 could be brought to that standard.

Re: [Elecraft] K2 or K2/100 + amp, QSK?

[Hank Kohl K8DD]

On CW, it depends on the amp.  If it is the "traditional" amp with a 
relay you will have the traditional VOX delay.  Or you could get an 
Ameritron QSK-5 and retain the K2's level of QSK.
However if you get a QSK amp, like some of the Alpha's or TenTec's, you 
can retain the degree of QSK that the K2 or K2/100 is able to provide.

Re: [Elecraft] Headphones

[Hank Kohl K8DD]

There was just a thread about headphones, comfort and the noisy shack on 
the cq-contest reflector.


First ... I have Heil Pro Sets - two of them. 
One pair is right out of the box several years ago. 
After about 5 or 6 hours they hurt my ears and head.
The other pair I got the new ear piece covers that look like a stocking. 
They are better, but I can't tell you why, but they just don't feel 
right after several l hours.
Neither of them keep a whole lot of ambient room noise out - like 
relays, blowers, kids, wife, etc.


Now for cq-contest reflector .
One short thread that I've found (Noisy shack? Here's the cure) recommends:
From KF9YR
http://www.racingradios.com/index.asp?PageAction=VIEWCATS&Category=12 
The David Clark headsets have 24 db noise reduction and cost 59.95.  It 
would be possible

to mount a boom mike on them if you really have to operate SSB!

Also, you could go the K6LL route.
1. Buy a Peltor H10A hearing protector 30 db noise reduction (about $25)

2. Buy two little speakers from Mouser (253-5405) $4 each.

3. Use sticky-back Velcro to mount the speakers in the hearing 
protector. Unless you have ears like Dumbo, there's plenty of room in 
there. Dumbo may have to pluck out some foam to get more clearance. Just 
run the wires over the ear cups. I used speaker wire from the 99 cent 
store, but RG-174 might be nicer.


4. Buy a Heil HC-4 or HC-5 element (about $33)

5. Take a one foot piece of #14 copper wire and solder a copper penny to 
one end. Glue or Velcro the HC-4 to the penny. Twist the other end of 
the wire around the headband wires of the hearing protector.


6. Glue some of the acoustic foam that comes with the HC-4 over the mike 
aperture to protect it.


Then K8DO recommends ANR aircraft headsets.

There are some nice stereo headphones out there that sound ok, but  I 
think I'm going to try a pair of ear protectors and the Mouser 
speakers.  Or maybe take the speakers out of one of the Heil's.


Maybe it's time for an Elecraft kit - Hearing protector, speakers and a

Make up the little 2 transistor keying switch that Elecraft posts on their site.
It works great.  Use it to key a shorting relay on the input to R2.
It will be activated before rf leaves the K2, and released after rf ceases.
That should be all the protection you need.

Hi, 

I am going to operate a little in the CQ WW 160 meter contest this weekend. My 
problem has always been too much noise on receive...I'm an alligator. I want to 
try using my 20-meter quad as a receiving-only antenna. 

The question is: the quad is right next to my inverted-L transmitting antenna. 
If the quad is connected to the K2 rant input, is there any danger of 
damaging the K2 when transmitting at the 1.5 KW level? 100 watts?

Re: [Elecraft] SO2R setup

[Hank Kohl K8DD]

In CT, CTWin, NA contesting programs the PTT delay is
used to immediately key the radio (and amp, if used), delay
the keying from the program for a user defined time, send
the CW from the PC buffer and quickly drop the PTT. 
PTT delay will not work with the K2 because it is common

to the dit line, or it will key the radio to full power, depending
on how the keying is set up.

I'm not sure about N1MM WroteLog and TRLog, but I believe
they are the same.

I have a box with a couple relays and a transistor to use LPT1
pin 14 to switch the keying line, amp relay line and eventually
(when I get around to it) switch RX audio.

Probably by the time I'm done with my homebrew box I'll have
the price of a DX Doubler and then some in it!

Just as a reminder to those of you who are contemplating SO2R operation with
the K2 - the stock K2 cannot properly use PTT for steering between the
transceivers when in CW mode because the PTT line is the same as the DOT
input.  If the SO2R enabled program steer CW by switching the keying, things
will work fine, but I believe there are some that key both rigs and depend
on the PTT routing to select the proper transceiver.  I am investigating the
methods used by various programs right now.

There is a 'cure' - take a look at my 'PTT for CW' article on my website
www.qsl.net for the schematic.  The photos currently have my 'haywired'
prototype, but I am working on a dressed up version that I should have
completed in about 3 weeks.  No changes to the electrical operation, but a
much 'prettier' packaging arrangement.

Re: [Elecraft] K2 - NOISY POLLING

[Hank Kohl K8DD]

I got rid of the computer polling noise on both of my K2/100's by
removing the right side panel and tucking the ribbon cable up as
high as possible - away from the main board.

Not that I would recommend doing it the way that I did it (with
the power on and CTWin up and running), but I could hear the
polling noise go away on each radio as I tucked the ribbon cable
up as close to the top cover as I could get it. 


Again I would not recommend that you do it with power on unless
you like living on the dangerous edge of life  in the K2 lane!!

Just a wild guess, but you may want to check the cable between the K2 and

Does anyone else have a problem with noisy polling with their K2 when
used with a computer logging program, and is there a cure for it?

I have two K2/100s which both have the 160m, NB and DSP options and
one has the SSB option.  I am using N1MM Logger with an old desk-top
(about 300MHz) computer under Windows 98 and when I listen to the SSB
K2 on any band with the AF gain at minimum, I can hear a soft pulse
every second or so.  This does not increase as the AF Gain is
advanced and normally the sound of signals, etc masks it, but it is
slightly annoying when tuning on a very quiet band.

Re: [Elecraft] Trip to Canada

[Hank Kohl K8DD]

Yes, you can take it along.
You should, however, take it in to US Customs at the border crossing and 
have it registered on a Customs Form 4457.  That will show that you had 
it when they looked at it!  And, when you return to the US and the 
Customs person at the re-entry point asks "what are you bringing back 
with you?" and you say "nothing" and he says "what about that radio that 
you bought in Canada?" . you will have the piece of paper that says 
you had it before you entered Canada.
If the Customs person wants to be a complete PITA, he can pull you into 
secondary and make life miserable.
If you have the original receipt for the radio, complete with the serial 
number, that should work too.


That said . I have gone to Canada and returned probably several 
hundred times with radios and other electronic "stuff" and only been 
questioned about Form 4457 one time . and that guy was almost a PITA!


And that said  it is far better to be prepared because US Customs 
can be one place that it is NOT better to ask forgiveness than it is to 
ask permission!So my best advice, after quite a few DXpedition trips 
that have taken us into or through Canada would be to take the safe 
route and have the paperwork!


And you can have fun operating /VE3!

   In the early 70's I had and instrutograph (sp) that used paper tape

computer generated code practice today.


   I made an offer to make code tapes for anyone that sent me a 
cassette.  A high school student call and I became an Elmer via 
telephone.  After several months of learning the code from the tapes I 
met him in person and gave him the novice code test which he passed 
with a perfect copy.  I was not required to test his sending but I had 
a CPO and key with me and had him try sending for his very first time.


   What he sent sounded like it was machine sent.  It was the only 
code he had ever heard.  He passed his novice, upgraded and kept his 
first call for over 30 years.  He also started with QRP and has stayed 
with it.


   My point is don't buy any key until you know the code and can copy 
with out effort at over 10 wpm.  Only then buy the paddles and keyer. 
There are far too many people who think the know the code who should 
be forced to copy their own sending.

Re: [Elecraft] The K2 and Random Antennas

Tom 

I would agree with Don!  The K2 & KAT2 should match it great . with 
or without the radials.
When I was a young General in about 1959 or 60 I had great luck on 80 & 
20 AM with a 60 - 65' longwire from the second floor window out to a 
tree.  The shack was on the first floor with about 40 ft of coax of 
questionable quality, and I used a tuner.  (WRL Globe Chief 90, homebrew 
cathode modulator, WRL tuner and an SX-99 and a homebrew TR switch).  
The more OT's that told me it shouldn't work, especially with no ground, 
the better it seemed to work!

Give it a try and be sure to report back when you put the K2 & KAT2 on it.

W3FPR - Don Wilhelm wrote:


Tom,

The KAT2 should adequately match the antenna system that you have, but I
would recommend that you scrap the coax and feed it with open wire line
because the feedpoint impedance on 40 meters and above should be a lot
greater than 50 ohms - the line losses and SWR on the feedline should be
rather high.

BTW, you could add a couple radials cut for 80 meters and use it on that
band too - the 60 ft wire is almost a quarter wave on 80 and it should
behave similar to a 60 ft high vertical (with some horizontal radiation too
depending on how much it slopes)

Depends on the amp and the keying speed, but I have found that for about 20

Depending on the amplifier, you may need to use a "relay accelerator"

160M board in it yet, but I don't think so.
That said, I don't like the KDSP2 at all for normal QSO's or HF contesting 
(160 is MF), but
it's like that hammer drill I talked the wife into letting me get -- when 
you need it to do the

job, you're glad you have it.
And the clock is cute!

I have a set from Kenwood and they are very comfortable and worked well
when we were on St Kitts.

Hi guys,

This discussion reminds me of something I've been wanting to for a while. 
I don't use the internal keyer in the K2 but prefer my
own keyer and I'd like to parallel my computer/cw keyboard with it. What 
kind of circuit would this require or could I just parallel

the lines together?


I don't use the internal keyer in either of the K2's either, so I parallel 
the lines together.  I use phono jack cables for most everything and use a 
"Y" phone cable to join the memory keyer and the PC keying lines.  Works great.

Re: [Elecraft] Hum coupling? - A real fix!

Supplies with big trnasformers, or even small ones carrying high current,

Switchers probably won't induce hum, but might cause in-band birdies by 
virtue of their switching frequency and (for some) lack of adequate filtering.

OK  here's the new program!



Supplies with real transformers can cause hum in the K2
Supplies with switching can cause birdies in the K2

What's the option?   No power supply?
No power supply, No hum, No birdies, No problem?
Well, the sensitivity goes to Hell in a handbasket.

The solution?
The new K2-PSQ and K2-PSH

K2-PSQ is a 4 amp power supply to power your K2 with a bit of current to spare.
K2-PSH is a 25 amp power supply to power your K2/100 with a bit of current 
to spare.
Both power supplies fit in an enclosure that fits right under your K2 or 
K2/100.  How do they do it?  SMT - the new technology.  Brought to you by 
the Godzilla PoWer company, Surface Mount Transformers that can deliver up 
to 1 watts of live of power.  In conjunction with Elecraft LLC, and 
QRP-L, Godzilla has miniaturized their line of very high power supplies to 
fit into the Elecraft KAT-100 1.5" enclosure with 99.89776% regulation 
(mandated by qrp-l, and several 6's).
Just send the name of your financial institution and a letter from them 
with a line of unlimited credit to . well, you get the picture!


Ok . wife brought the little white pills to calm me down and said she 
will let me go back to the shack for some 40M cw in a short while.  They 
tell me I haven't been the same since Godzilla came out with the 3 db per 
hundred feet gain special coax.  Guess I never should have ordered that 
1000 feet spool!
