Re: [Elecraft] k144XV Rocks--Indeed...

[John Ragle]

Hi, Steve...

 I beg pardon for using the reflector, since this is more or less 
cracker-barrel and store-front stove stuff, but your comments remind me 
of years ago when I first tried 2 meters. I heard this weak CW signal 
down in the noise on my vertical antenna/10 watt rig. the guy was down 
in Connecticut, about a 50 mile run for me, and he kept telling me "turn 
your beam toward me..." He was one of the (then) big guns in EME, and 
made me realize that there was something besides noise and FM on 2 meters.

 I went out the next day and bought an antenna -- a REAL antenna, a 
10 element collinear array with horizontal polarization -- and then 
discovered that there's lots of activity on 2.

 The message is (like the real estate guys say...) antenna, antenna, 
and antenna! I am using a 10 element Yagi from Cushcraft, up about 35 
feet at the present time. It was on a guyed flagpole with a TV rotator 
at first, but has now graduated to a better set-up...details are not too 
important.

 I routinely work 100-200 mile distances on tropo scatter, and have 
worked into the Gulf coast, the Mississippi basin, and the upper Great 
Lakes area  on SSB and CW when there is either a tropo duct or 
sporadic-E. In your location, there are probably not many tropo duct 
openings, but you can monitor

http://www.dxinfocentre.com/tropo.html
and
http://www.vhfdx.info/spots/map.php?Lan=E&Frec=50&ML=M&Map=NA

for further information.

 One comment: if propagation is good, then 10 watts will carry you 
quite a ways. For routine tropo scatter, a bit more power helps, but 
then one is into "heavy equipment." I am using a TE Systems amplifier 
and a 70-amp Astron power supply, but there is a wide range of other, 
equally-good, solutions.

 The K144XV is a good exciter. I am using its older brother, an 
XV144, from the same fine source at Elecraft. It gets along just fine 
with my K3.

 Don't neglect the CW portion of 2 meters. CW is a great weak-signal 
mode. People seem to hang around just below the USB calling frequency.

 And, don't forget about 6 meters ... same comment about antenna! 
... from here during the summer season Europe is more or less routine in 
the morning: I just worked Spain and the Canary Islands with S7-S8 
signals on 6. Your location gives you a tremendous advantage WRT working 
all states, as you are more or less central. I despair of working KL7 or 
KH6 on 2 from here, except by EME, unless Ole Sol does something 
spectacular.

 Have fun, and learn a whole new aspect of our wonderful hobby!

 s to say I was shocked.  Granted he had a tall tower and 11 element 2 meter 
antenna pointed my way but still...There I was with a dinky little vertical 
whip sitting in my basement running 10 watts and talking with this guy 50 miles 
to the north in another state.  The bug struck and now I too ordered the 
internal 2 meter option for my K3 SN 176.  Who knows maybe I'll get into moon 
bounce, ha.  Anyone have any suggestions for a 2 meter amplifier for the 
station?  Thanks again Elecraft for putting the fun back into the hobby.  Best

[Elecraft] low power on 6 meters

[Robert Garceau]

I have seen this issue posted before, but no answers that I can see.

 

I have a K3 and the output is no more than 52 watts with an swr of
1.23..sometime get it up to 62.

 

Now I have the KPA500 and using 40 watts to exite the amp, I get just a tad
over 425 watts.

 

Don't think I want to push it over 40 watts. And to be honest there probably
isn't much difference between 425 and 500, but would like to know why I
can't get the 100 like I should..

 

Bob, W1EQ

[Elecraft] K3/P3 interaction?

[Tommy Alderman]

I'm trying to re-familiarize myself with my P3, which is running with MCU v.
01.09. 

With Mkr A and/or B turned on, if I adjust the 'offset' control on my K3
(and RIT/XIT is not ON), VFO B cursor and Mkr B randomly jumps across the P3
screen. If I turn RIT or XIT ON, the P3 VFO B and Mkr B seem to operate
normally (meaning they no longer jump around the screen).

I haven't finished going through the P3 manual yet, but is there some
setting to prevent the random cursor/marker from jumping around the P3
screen?

Thanks.

Re: [Elecraft] K3 RTTY with morse key

[Jim Sheldon]

This is exactly how it's supposed to operate.  There IS a character which you 
can send from the paddles to make it switch out of transmit and that is dit dit 
dah dah sent as one character (dididadah) that will switch immediately back to 
receive.  The "Idle" is called "diddle" in the RTTY world and is either 
continuous "letters shift" or "blank" characters which were used to keep the 
mechanical decoders on real teletype machines active and introduce less 
distortion, thus cause less missed characters during the receiving of slow 
typing.

Welcome to the world of RTTY.  There is a free program out there dedicated to 
RTTY that works very well with the K3 and others called MMTTY, written a few 
years ago by a Japanese ham, Mako Mori, JE3HHT.  It has, probably the best FFT 
decoding algorithm for RTTY available and once you get it set up it works right 
down almost to the noise (just like the K3).  Google MMTTY and get version 
1.68a which is the latest.

You might want to also look at W3YY's website and think about the little 
interface he has available.  It isn't cheap, about 30 bucks shipped, but it's 
an opto isolated PTT, CW and FSK keying interface (only for transmit) that will 
interface the computer to the K3 (needs a second RS-232 port) for sending true 
FSK (that way the dial freq in FSK-D) will match the MARK frequency on RTTY.  
Also, the international standard for RTTY is to send it using LSB or it will be 
sent inverted and you will have to use RTTY Reverse in the program to copy.  
The W3YY interface hooks up to FSK, PTT and Ground using the 15 pin VGA style 
plug on the back of the K3, the CW out of the YY would plug in to the Hand Key 
jack on the back of the K3.  

I've no fianancial connection to W3YY, but have been using one of the 
interfaces ever since getting the K3 and since I operate a lot of RTTY, it 
makes things much easier.

Re: [Elecraft] What have I gotten myself into???

[George Winship, NC5G]

What have you gotten yourself into? Probably more fun than you deserve. HI!
Don't get in a hurry, read each step two or three times, install the part,
double 
check to make sure it is in the right spot and orientated right and solder.

I had not soldered anything more difficult than a PL259 on a piece of coax
in 
20 years when I got my K2. A little solder practice and then a blast to see
the 
radio come to life. After 10 years, it is still a thrill every time I turn
it on.

Enjoy the journey.

George, K2/100 #2217

David - same situation here - built K1 and a bunch of other stuff - then
when I lifted the cover of the K2 box when I got it, and saw all those

Turned out great.  One piece at a time.  Don't rush and don't worry about

Re: [Elecraft] K3/100 Perfect condition at eBay

[Mike K2MK]

Hi Levent,

On your eBay ad stating "all modifications" I notice that the upgraded DSP
board with low pass filter has not been included. Certainly S/N 1230 did not
include the new board. 

This is not a negative comment on your sale but I have noticed this before
on K3 sales. Is it possible that when an owner sends his K3 back to the
factory and requests "all" hardware mods, Elecraft doesn't mention the DSP
upgrade.

I found the mod listed on the following page
http://www.elecraft.com/order_form_parts.htm#K3%20Parts
I see that the full board swap costs $110 and if only the low pass filter is
desired the cost is $40.

73,
Mike K2MK

Re: [Elecraft] low power on 6 meters

[WILLIS COOKE]

Bob, do you have an amplifier in line on 6 meters?  I have noticed that my 
Clipperton L absorbs about 15 watts on 6 meters even when it it turned off.  It 
does not do this on the lower bands.  You can easily find out by taking the 
connectors loose on the amp and replacing with a short barrel connector.  May 
not be your problem, but it is mine.

[Elecraft] K2 Problem in NAQP

[Jim Harris]

Hi Folks,

I ran into a problem during the just completed NAQP RTTY contest with my 
Elecraft K2.  To make a very long and frustrating story short, on at least 20 
and 40 meters it receives on the lower side band but transmits on the upper 
sideband.   On 15 meters it receives and transmits on the same sideband which 
appears to be the lower sideband.  The only way I was able to get it to 
transmit on the same sideband on the two bands mentioned was to put the radio 
into RTTY reverse (with CW REV) and then operate MMTTY in REV.  As a result of 
the problem I lost about three hours in the contest while troubleshooting the 
problem.  If someone can shed (and I'm sure they can) some light on this 
perplexity, I would very much appreciate it.

This was my first serious attempt to do SO2R.  I used my K3 for the right radio 
and the K2 for the left.  I had aligned the RTTY filters in the K2 using the 
procedures found on the internet and used Spectogram.  I tried to be careful to 
set them on the correct sideband.  I can accept that maybe I didn't get that 
done right and will recheck them.  But, I don't understand why the upper band 
is correct and the lower bands are not.  

BTW, I ran both radio's pretty hard at 100 watts and neither overheated.  The 
K3 takes care of itself very well.  I think one could go near brick down for 
several minutes and it would be fine.  I used a hand held, point at an object, 
temp sensor with the K2 and the highest heat sink temp I measured was about 100 
F..usually it was 10-20 degrees lower.  I have manually adjustable variable 
speed four inch muffin fans mounted about three inches above each radio and ran 
them continuously at about half speed during the contest.  With a little 
external help I see no problem in running the K2 at 100 watts FB in RTTY 
contesting.

Thanks for all the commits I'm sure I will receive.

 

Take pride in the USA. 73

Re: [Elecraft] Looking for miniature 14-V power supply for travel use

[AD6XY]

Hi Wayne, 

I expect you are back by now. However it might still be of interest. I have
been using laptop type supplies for this application. Light, small, cheap
and some of them are relatively quiet. They will also fit in a small metal
box. Recently I came across LED lighting supplies, 12V again and similar to
laptops except they come with standard 2.1mm plugs. 

For quiet and off grid applications, I use LiPo batteries, 3 or 4 cell. For
the KX3, 3 cells will do and can be re-charged with a cheap balance charger.
I have a small one to hand, 20x40x100mm 2.2Ah and a 4AH 4 cell 20x50x120mm. 

My own application is powering portable microwave gear, but 12V is
universal. Fusing is essential of course as these cells will happily deliver
60Amps. They have a reputation for danger if you miss-charge them. But
people still fill up their cars with gasolene to go on holiday and that is
much more dangerous.

Mike

Re: [Elecraft] low power on 6 meters

[K4ia]

I notice high swr when my AL572 is in the antenna circuit - even when turned 
off.  When I hook the coax directly to the K3, the swr is 1:1. Haven't figured 
out why except maybe there is a low pass filter built in the amp that is in 
line all the time.

[Elecraft] Headset recommendation for the K3

[todd brady]

Hello to all on the list 
I'm a relatively new K3 owner, and this is my first post to the group. I 
purchased my K3 back in March ( SN# 5331 ) and just recently purchased the P3 ( 
SN# 1435 ). 
First of all let me say the customer service is hands down the best I've ever 
experienced, and the user group has been a wonderful help to me, as I learn the 
art of operating my K3 !!
I enjoy both SSB and CW   although I don't ragchew using CW, I do chase and 
work DX in that mode. 
I have tried various headsets with my K3 including the Yamaha, that so many 
here on the list recommend.
I have found a new headset that I like better than any I have tried, and I just 
wanted to recommend it to the group. 
I enjoy both SSB DXing and contesting and this headset is great for all SSB 
applications. 
It's the " Turtle Beach /  Ear Force Z1 " ... Its a light weight gaming headset 
designed for PC's and it's only $29.95 ... I picked it up at Walmart. The sound 
of this little headset on both TX & RX will surprise you !!
For more info on the headset ...  go to my blog at www.n4la.com
Thanks for all the tips everyone, and yes I'm a very satisfied K3 owner !!

AFAIK there are no plans to modify the K2 firmware to work with the P3,
but there are plans to modify the P3 firmware to work with the K2.  It
will never be as closely-integrated as the K3, but most of the features
should work, including readout of the K2 frequency on the P3, click to
QSY, accurate amplitude display, etc.  The main feature that won't work
is fixed-tune mode.

It's on the list.

Re: [Elecraft] low power on 6 meters

[WILLIS COOKE]

The input circuit is bypassed by the relay so the only thing in the path is the 
relay, coax connectors and the wires.  I think it is the wires.  I have no such 
difficulty on 10 meters.  My amp is the Dentron Clipperton L with the AD5X QSK 
mod.  The connecting wires are about 2.5 inches long.  The QSK mod works great 
on low bands when the amp is on.  The relay noise is less than the fan noise 
and 
it has survived several thousand QSOs with no problem other than 6 meters.  The 
Dentron is the predecessor to the AL572 with the same tube lineup and a bit 
more 
compact layout.

Many thanks for posting your find, Todd.  Thanks to the size of the 
market, there are hundreds of low cost headsets made for use with 
computers -- everything from gaming to Skype to listening to music. If 
you are able to sell in quantity, it's much easier to get the cost down. 
That's why we have the excellent Yamaha headset at such a low price, as 
well as the one you found. Someone on the Ten Tec list found a Koss 
headset that he liked a lot. Several months ago, I went shopping at 
Fry's for low cost headsets to use with Skype. I found a half dozen or 
so priced between $10 and $25, and I bought three that looked promising. 
All three "worked," but none was really comfortable, and one set was 
like having my head in a vise. Quite a few years ago, I bought a 
Plantronics salesman's sample kit at the Milwaukee hamfest and made 
connector adapters to hook them up to my computers and ham gear.  All of 
them worked, but only one was comfortable enough to use for more than an 
occasional phone call.

The beauty of the K3 is that, thanks to its flexibility, it can work 
quite well with almost anything that we can plug into it!

Many of these amplifiers use open frame relays and long connecting
wires for the T/R (bypass) switching function.  The inductance of
the wires/long relay contacts causes a significant impedance bump
on six meters (and to a lesser extent on 10 meters).

If you want to to resolve the problem connect a small capacitor from
the "bypass wire" (the connection between the two normally closed
relay contacts) to ground/chassis.  You will need to experiment -
or use a trimmer - the capacitor value will be small, typically less
than 10 pF.

Re: [Elecraft] K2 Problem in NAQP

[Don Wilhelm]

  Jim,

I suspect you have the sidebands inverted in your RTTY filter set.

Do the following with the K2 set to a band lower than 15 meters,

First set the FL1 filter to use the OP1 filter on the KSB2 board, and 
that filter along with its BFO settings will be used for transmit.  Set 
RTTY the same as your SSB FL1 settings - the BFO setting for RTTY should 
be the same as LSB, and the RTTYr BFO should be the same as USB.

The other filters are created from the variable bandwidth filter.  I 
usually set FL2 to 1.00, FL3 to 0.70, FL4 to 0.40, and center these 3 
filters at 1000 Hz. - use Spectrogram
MMTTY mark frequency is set at 915 Hz to be compatible.

Check the BFO frequencies for RTTY and RTTYr - normally the RTTY BFO 
frequency will be in the vicinity of 4914.xx and the RTTYr BFO will be 
near 4912.xx if you are using 1000 Hz as the center frequency.

Higher center frequencies may be possible, but you may run into 
difficulty with limits of the BFO range for RTTYr.

The K2 reverses its mixing scheme on 15 meters and above - below 15 
meters the VFO and BFO subtract while on 15 and above the VFO and BFO 
add.  The K2 automatically swaps sidebands for you, but it will not come 
out right on all bands if the sidebands have been inverted in the filter 
settings.

73,
Don W3FPR

[Elecraft] Elecraft FTDI N1MM

[Mike Greenway]

I noticed that Elecraft if now offering a FTDI cable.  When I bought my K3 they 
only had a Prolific cable.  It works fine for downloading Elecraft updates but 
have never been able to get it working on N1MM.  Wonder if anyone has used the 
FTDI cable offered by Elecraft to control their K3 via N1MM?  Everything I read 
points toward using FTDI type cables with the K3/N1MM combo.  73 Mike K4PI

Everything will go just fine. As I'm sure you know, you should take your time 
and work slowly but carefully. I managed to build a K2/100 with a number of 
accessories over an approximately 2 month period. Everything worked well when 
it was finished. It is a lot of fun. Best of luck and I'm sure we'll have fun 
working you when it is finished.

Looks like Elecraft has busted through the early April log jam of initial

Re: [Elecraft] low power on 6 meters

[WILLIS COOKE]

The relays in most amps are open frame and definitely not designed for six 
meters.  Mine is an aftermarket kit designed for an AL600 and modified by me to 
work on a boat anchor Dentron Clipperton L amplifier.  I am just offering a 
suggestion about what might be causing the problem, not looking for a solution 
from someone.  The elegant solution is to buy a KPA-500 that is designed to go 
with the K3 instead of using a Boat Anchor designed to work with a TS-520 or an 
FT-101.  The easy solution is to turn on the KAT-3 or to not look at the SWR on 
the K3.  The other solution is to disconnect the coax from the AMP and put in a 
barrel connector.  As for me, I have another 500 buro QSLs to answer today, so 
I 
must be getting out.

I am sending this again - as a further test.

Excuse the bandwidth, but I have recently sent messages to the reflector

Re: [Elecraft] order form questions

[Dick Dievendorff]

The KXV3a provides the IF tap needed for a panadapter (as well as Rx Antenna
and transverter I/O).

You only need a KUSB if you require a USB to Serial Adapter.  If your
computer has an RS-232 serial port (typically DB-9), you don't need a new
KUSB.  You will need a "straight thru" 9-pin serial cable to connect from
your PC to the 9-pin D shell serial connector on the back of the K3.
Details and pictures of the cables are in K3 Utility Help.  You can install
the K3 Utility and view its Help File ahead of time.

Your list is fine for "up and running".

I don't know what the free 144OPT100 is, either.   I put together a
tentative order with a K3/100, KAT3-F, KXV3A, MH2, P3-K and didn't see a
144OPT100.

Re: [Elecraft] Test

  I was also told privately (not sure why he did not post it) that he 
has a similar problem when using gmail from his Thunderbird email client 
(or I assume any other local email client).
OTOH if he sends from the gmail webmail he sees his own post.

the email will make it to the list
the party sending the email to the list

please clarify what you mean when you say:
"not seen them appear on the list"

where/how are you looking to see if they are being posted?

are you referring to on your own computer, in it's email client?

or perhaps archives of the list online?

[Elecraft] Digitally signed email to the Reflector

[Dick Roth]

I have sent a couple of messages to the Reflector that have earned me
the bounce message below.  I believe it is because I digitally sign my
email using PGP.  Can anyone verify that this is the cause and why it
should be so?

This message is sent without my digital signature, so I think I won't
get the bounce message.

Thanks for any explanation.

Re: [Elecraft] Digitally signed email to the Reflector

The reflector probably sees the PGP signature as an attachment, which

Re: [Elecraft] Test again :-)

[Jeff Cochrane - VK4BOF]

Hi guy's,
I hope you can see this as I won't.
"Why's that?" you ask, because I too use GMail's email service and I have NEVER 
seen my own postings to ANY mailing list whilst I continue to use a GMail 
account for posting.
I have raised the issue with GMail and to date there has been a deafening 
silence in reply.
So, I just accept the fact now that I cannot see my own postings to the 
reflector, not that it worries me greatly because I can see them in my sent 
items folder.
I use MS Outlook Express for sending email via pop3 on GMail. (It aint too 
flash, but it is free and is well integrated into the OS of choice that I use. 
(WinXP)

Re: [Elecraft] Test

[Dave Wright]

For mailing lists, Gmail typically does NOT reflect back whatever you post to 
the list. 

It automatically filters out the posts that you send to avoid duplication in 
your gmail mailbox. Every list I belong to is the same way; I subscribe to them 
using Gmail and I never get my posts back, but they are posted to the mailing 
list. However, if you go to the online version of the mailing list, you'll see 
that your posts are getting through.

[Elecraft] K2 modification of the variable BW Cohn CW crystal filter

[Stephen Rector]

I ve been using me K2 (s/n 6770) in the digital modes lately and have wanted to 
make an improvement in the passband ripple, which is almost 10 dB p-p when the 
BW is set at 2 KHz, with the RX audio viewed spectrally. So I simulated the 
filter using the crystal parameters given here:  
http://www.arrl.org/files/file/QEX_Next_Issue/Nov-Dec_2009/QEX_Nov-Dec_09_Feature.pdf
 , using the spice simulator Qucs at http://qucs.sourceforge.net . The 
simulation agrees with the measured passband when I set the termination 
impedances between 200-300 ohms, with the ripple being more pronounced as the 
impedance is lowered.

I found a reference on the web to a modification of the Cohn filter which 
preserves the equal capacitances and crystal parameters for all elements, 
documented by G3UUR and described (page 5) here:  
http://www.warc.org.uk/filestore/projects/xtal_bpf_203/eDishalHelp.pdf . I 
haven't gone into the mathematics of this alteration, but the effect of placing 
a crystal in parallel with X7 and X11 is a de-Q-ing of these two elements and 
substantial reduction of ripple at the passband edges. This effect is 
apparently not unknown to Wayne, who uses it in the BFO resonator and 
considered it for increasing the pullability of the PLL reference. I don't have 
the 2010 ARRL Handbook, but G3UUR has an article in it describing his 
modification of the Cohn ladder response.

So - the mod I tried in simulation was to place a crystal in parallel with X7 
and X11, and to replace the coupling varicaps D29 and D34 with 4700pF fixed 
caps. The varicaps D30-33 are untouched. My simulation results:


K2 design:
With Cvc = 44pF:

6dB BW = 2.07 KHz, 60 dB BW = 4.55 KHz, ripple = 9 dB p-p, shape factor = 2.2.

With Cvc = 200 pF:

6dB BW = 0.57 KHz, 60 dB BW = 1.52 KHz, ripple = 1.5 dB p-p, shape factor = 
2.67.

Modified K2 design, G3UUR topology:
With Cvc = 56pF:

6dB BW = 2.03 KHz, 60 dB BW = 5.31 KHz, ripple = 3 dB p-p, shape factor = 2.61.

With Cvc = 205 pF:

6dB BW = 0.57 KHz, 60 dB BW = 1.96 KHz, ripple = 0.5 dB p-p, shape factor = 
3.50.

So it looks like I get a substantial reduction in passband ripple and a flatter 
group delay with the modification, at the cost of a bit of increase in the 
shape factor. If I used the K2 strictly for CW or psk31, I might not want to 
make a change. But I use wider digital modes like Olivia where group delay 
distortion can make a difference in BER. So I think I'm going to try the mod. 
Don has suggested in the past to narrow down the passband when using the 
digital modes, but this makes enough of a difference above 1 KHz BW (and I see 
surrounding signals in the waterfall), that this mod is worth a try. I'm 
curious if anyone on the list has considered it.

Re: [Elecraft] K2 modification of the variable BW Cohn CW crystal filter

[Don Wilhelm]

  Stephen,

If you are doing mostly digital modes and not too much SSB, you might 
want to change the OP1 filter instead.  The SSBCAPKT contains capacitors 
to make it either a 1.9k, 2.1k, 2.4k or 2.6k filter.

Re: [Elecraft] order form questions

[Jim Rhodes]

Under the K144XV option there is a checkbox for K3/10 or K3/100. If you
check one of these boxes the system thinks that you are ordering the K144XV
and need the appropriate rear panel. The 144OPT100 is the rear panel for use
with the K144XV option on a 100 watt K3. Just don't check that box as you
don't seem to be ordering the internal 2 meter transverter.

Re: [Elecraft] K2 Problem in NAQP

[Jim Harris]

Don,

That was the leading suspect in my mind.  But I tried very hard to assure they 
were correct when I set them up.  I still don't grasp why the upper band was 
correct and the lower were opposite.  I realize there is an inversion of side 
bands up there but I thought it was a simple inversion which to me means they 
should have behaved as did the lower but maybe opposite from the lower on 
receive and transmit.

I will follow your instructions and see how they work out.  As always,  thank 
you for your assistance.

 
Take pride in the USA. 73


Jim, W0EM

Re: [Elecraft] Elecraft SSB Net results (7/17/11)

[Lyle Johnson]

I made a couple of calls on the KX3 prototype I have here after the net, 
but propagation wasn't very good and no one responded.

Re: [Elecraft] What have I gotten myself into???

[Tom McCulloch]

It took me about 80 to 100 hours - spread over 6 to 9 months -- but that 
was just my own pace...if I would have done it in 6 to nine weeks it 
undoubtedly would have gone quicker.  I took my time and enjoyed it.

Lots of guys on this list can offer lots of top notch advice based on 
their own experiences -- my 2 cents is as follows:  I like to check each 
solder connection to make sure I don't have a cold solder joint or put 
the lead in the wrong hole -- so to facilitate this I made a photocopy 
of each of the PC boards so I could easily check the traces...If 6,000 
guys built a K2 (what s/n are they up to anyway?), you'll get 6,000 
building different tips -- and they'll all be good!  This is a fun kit 
to build and this list list is a great resource---have fun

[Elecraft] K2/100 Pa transistors

[W2bpi1]

I had forgotten I was to retighten the screws that hold them to the heat  
sink after 5-10 hrs operation. I know I was way past the 5-10 hrs. Was I  
surprised how loose the screws were. Lucky I did not wreck the finals. DONOT  
SKIP THIS STEP!  73 George/W2BPI

[Elecraft] Elecraft CW Net Report for July 17th & 18th, 2011

[Kevin Rock]

Good Evening,
Twenty meters was very nice today.  Twelve checkins over a period of  
about 40 minutes.  Much nicer than last week's skunk :)  Most of the  
signals were quite strong while a few of the eastern stations had some  
QSB.  Some of the southern stations had fast and slow QSB which made life  
a little interesting.  But hearing folks is much nicer than calling CQ  
while reading a magazine!
Weather reports for the most part were much warmer.  Only Brian down in  
California came close to my 55 degrees.  I just went for a short walk and  
there was a warm breeze off the coast.  Not warm enough to put out the  
fire but it is better than the rain and 45 degree nights I have had  
lately.  Last night I had a mosquito flying around the keyboard but it was  
not very aggressive so it is warm enough for them.

On to the lists =>

Thank you for the fun nets.  I enjoyed hearing from you all.  It was  
very nice to hear improvement in twenty meters.  Forty meters was about  
the same as last week since it would not get over the Rockies as it has  
many times in the past.  But with the days beginning to shorten I expect  
it will get back to better propagation at net time soon.  It is noticeably  
moving southward at each sunset.  The flowers have also changed to the  
orange and purple hues of mid-summer.  While I was out walking just now I  
heard a mourning dove.  His call was not what I had grown accustomed to  
when I grew up in Wisconsin.  Not enough beats on the end.  I wonder how  
much variation there is in bird calls over their normal range?
Until next week stay well,
   73,

Re: [Elecraft] "Q" signal trivia

In commercial radiotelegraph in the past, they were generally presented 
in the opposite order ... you ask the question "INT QRM" meaning, "Are 
you bothered by interference?," or "INT QLB KPH 6" meaning "Have you 
monitored KPH on 8 Mcs and if so can you report their signal strength?" 
and the answer "QRM" meant "Yes, I am bothered by interference."  If you 
weren't bothered by interference you responded "N N K", or "NO K."  "N" 
and "NO" work for a great number of languages, as does "OK".

If you had monitored KPH on their 8 Mcs, you might report "QLB KPH 6 QSA 
4" meaning "I have monitored KPH on their 8 Mcs frequency and I report 
them as QSA 4."

In that service, "INT" [di di dah dit dah sent as one character] was the 
interrogatory, and preceded the question you were about to ask. [INT 
QRL]  The Morse question mark is "di di dah dah di dit] which duplicates 
the prosign "IMI" meaning either "please repeat last" or "I will repeat 
last".  Those with commercial radiotelegraph experience may remember this.

INT never made it into ham practice as [I think] we found that we could 
easily distinguish a "?" from an "IMI" from context.  Of course, we were 
also not handling traffic for a price for a communications company who 
had a rule book and a Chief Op standing behind you about to box you on 
your ears if you screwed it up. :-)

Very true in commercial marine and aeronautical radiotelephone service. 
  Hams, being inventive and prone to thinking out of the ITU box, have 
nounified and verbified [and in some cases adjectivified and 
adverbified] International Q Signals.  QRM is too many stations on the 
same frequency, generally a noun, as is QRG ["HIS QRG?"].  QRQ can be 
either ... a noun denoting high speed CW, or a verb [QRQ] meaning "speed 
up."
>
> Oh ... 73 is correct.  73's isn't.  73's is equivalent to "Good lucks".

I'm not the expert, but I have always thought 73 meant "Best Regards." 
Thus, "VY 73 ES GUD DX" meant "Very Best Regards and Good DX."  73's 
would then mean, "Best Regardeses."

But, if you tell me "Best 73's" on phone, I will take it as a gesture of 
good will toward me, and thank you for that.

Re: [Elecraft] Elecraft FTDI N1MM

[Steve Ward]

Mike,

The Prolific cable always worked for me on Windows XP but when I 
upgraded to Win 7 I could not find a driver that would not blue-screen 
the system.  The new FTDI cable works great with all software I've 
tried, including N1MM.

73,
