PA3CLQ's Leuke Linken Nr. 484
I1QOD make copies of the PS-213 key.
He is a retired
aviation tool and die machinest and perhaps the fastest Morse
operator in the world. He knows a good key.
G0NVT makes a variation of the key.
He is a retired Royal Navy Machinest, he does excellent work, especially with his historic reproductions.
I am blessrd to
call him a friend whom company I enjoy when he visits.
I would buy a PS213 from Alfredo, I1QOD.
He made a improved faithful reproduction.
Improved because he put a beeded base on tge key, and corrected the earlier keys structural weakness.
I have not tried Begali's best straight key, but I have used his best sideswiper from the same signature line of quality and that key is true perfection.
I have sent the
same amount on other sideswipers as Begali's top of the line, and had
I known how good this key was, I would have bought it and never ever
bought another sideswiper.
Probably the best hand key has been made with the same care, but I have not used it.
The best straight key I have ever used is the PS-213A key, it has a beautiful feel.
The second best key is a copy made by G0NVT custom made for me with a full sub-base to stop tipping.
An excellent key which captures nearly all of the feel of the PS-213A.
The real one is
just a bit better.
The G0NVT current version has an ingenious basket spring tension and is a simplified version of the PS-213A reproduction he made.
I had both but but I liked the one custom made for me.
versiin is a very good key, but I would buy I1QOD's version as it is
more authentic and I think the G0NVT curent simplified design changes
the feel for me.
Right below these keys are the Marconi 365 keys, Amplidan, SRS Lennart Petterson, GNT Copenhagen (later made in UK), NATO key, Junker, Baumaster
Those are my comfort keys.

RRI EMCOMM Exercise - CW
Many SKCC members enjoy QRP and portable operation.
some of you may be interested in an upcoming Radio Relay
International EMCOMM Exercise, which will emphasize portable CW
This is a nice chance to get out in the field in the Springtime, set up a portable CW rig or QRP arrangement and demonstrate survivable CW operation
in a public park or similar setting.
Complete details on the exercise are available at:

End Fed Half Wave wires
I need to redo my antenna infrastructure after having solar panels installed on my house.
I'm thinking of
going for an end-fed half wave.
In the MFJ ad they claim the EFHW will cover 80 m - 10 m without a tuner.
If you have experience, good or bad, with an EFHW, I'd like to hear from you.
via the group or personal email is fine.
Thanks for your help!
I have used a Myantennas.com 8010 EFHW for field day and other portable ops.
It's a a great antenna at 80' or 30'
The construction is much better than the MFJ version.
SWR across all bands is excellent.
I am going to put 2 up at my new QTH perpendicular to each other to cover some lobe gaps at the higher frequencies.
support is awesome.
I have been using an EFHW by MyAntennas.com for three months now with good results.
Due to unique circumstances it is mounted on each end by ROHN telescoping masts about 30' high.
The transmission line end also has a 6M ground-plane antenna mounted above it.
I am looking to get a second to support portable ops.
My radio's internal tuner hasn't had a problem.
One shortcoming is the lack of 60M.
EFHW-8010-HP Multiband End Fed Half Wave Antenna 130 Feet (39.6m) long #18 or #14 wire
NO TUNER needed!
Perfect for ALE HFLink, ARES, EMCOM …
Resonant on 80/40/30/20/17/15/12/10m 1.5 kW-ICAS max.
73, Jeff de KC3HWU
I use an EFHW for 80 - 10 meters made by MyAntennas.
130 feet long I use it as a sloper from 50’ down to 15’ at the peak of my roof.
No counterpoise required and tunes up without a tuner.
impressed by the performance Check it out at:
Feet to meters conversion:
I use the EFHW-4010 from myantennas.
It has worked well for me.
The only problem is running high power.
The balun will only support 100W on WARC bands.
On 40M running 500W after 5 minutes the SWR started to go higher probably the balun heating up.
The balun was supposed to support 1000W ICAS.
I bought a higher power balun and all is well.
bands are still limited to 100W.
Hi Steve & all,
I tried one form of end fed HW, the Zepp, fed with balanced line.
When I tried it there was so much RF in the shack the rig locked up on transmit any time I increased output beyond 20 W ! I took down and reconfigured this antenna to a center fed antenna.
The problem was
resolved, even with the balanced line coming right into the shack.
CW is Real Radio 73, John...K8JD
I made a page on end fed antenna calculations a few years ago:
Maybe useful, maybe not since nearby objects in the environment can affect ideal length.
you have a capable tuner shoot for closest to halfwave, if a less
capable tuner then avoid them.
GL es 73, Mike ab3ap
I have an EF wire, but not EFHW, and I do use a tuner.
The wire length is such that it can be easily matched for 10-160.
The 10:1 ATU in
my K3 can handle it but I use a manual tuner to keep the RF a couple
of feet farther from me and the mouse & keyboard than it would
otherwise be if the wire went straight into the back of the K3.
Is my K3 ATU or manual tuner more efficient than the MFJ "no-tuner" EFHW? I don't know.
I can regularly
make contacts on all bands with it. Mostly use it for 20 thru
The MFJ no-tuner antenna would of course be more convenient to operate.
But I don't mind cranking my manual tuner; in fact, I kind of like it.
It's a bit retro with the surplus "ANTENNA LOADING" roller inductor and big Hammarlund knobs.
It's bigger than my K3!

I would go with the PAR antennas from LDG antennas.
I have several
bands of this antenna along with the trail friendly 40/20/10 antenna
which travels very nicely with my FT817 when I travel.
The other option is SotaBeams from the UK.
I also have several of these and like them almost as much as LDG.
They also make
antenna masts that are great for travel as they shrink down small
enough to fit in your travel bag.
Good luck in finding an EFHW antenna.
are on the right track.
Aron Brown NN1F
Two more thoughts:
1) I needed to put a common mode choke at the feed point of the antenna.
I also put one in the shack at the amp.
I did this to
reduce RF in the shack with this antenna and also on receive it cut
down the noise received significantly.
2) On 40M my VSWR is just short of 2 - 1 which is just under the minimum required for the AMP.
My VSWR is OK on all other bands without a tuner.
I have seen
some discussion that there can be VSWR problems with this antenna on
the highest band (40M in my case) when the feed point is high in
And some people
have solved this by lowering the feedpoint.
Thanks, Bruce, WB6IZG,
I live in a very grouchy HOA so have had to get by with antennas not visible from front side of the house.
My choice for
the past few years has been an end-fed long wire with a 9:1 UNUN
feeding 53' of "16 gauge stranded, insulated copper wire
suspended from a 20' pole at the back of the house out to a 16' post
in the back yard. With 25' or more of coax feed line, no counter
poise is required, and I experience satisfactory SWR (2.5 or less) on
all bands 6-160 with minimal tweaking of the tuner in my K3 (most
frequencies I see 1.1 or 1.2:1).
The UNUN is from Balundesigns.com.
It is $50 for their 300W model, slightly more for the KW version.
their web site they suggest a list of optional wire lengths,
obviously the longer the better, all the way up to 170'+ as I
To me, this is the best thing since sliced bread, considering that I can work anything I can hear, and that's enough to capture SX2 in very short order here in SKCC, with only 10 remaining for SX3,
I hope this testimonial might inspire others to give this simple and cost effective antenna a try, especially if you are one of those who wishes a way to cover more SKCC frequencies and bands efficiently.
Cheers, Mike, K5MP

Automatically introducing more characters and using actual combinations that will be received in contacts are innovative ideas.
It is a much
better way to go than the brainless "slogging" that is
We old wheezers have to keep in mind that long, long gone are the days when the beginner could cruise the c.w. bands to find a station operating at just the speed he needed to learn from.
Gone, too, are the 20w.p.m. press and high seas maritime traffic.
propagation the way it is now, for many of us the c.w. bands are
either an empty desert or, with a contest on, shoulder to shoulder

If we old curmudgeons had been offered a tool like this, many of us would have welcomed it!
We used old

Seems to me that anything that encourages the learning of morse code is worth a serious look and try.
Ben VE1AHX, brand new to SKCC On the air since 1952
I think it is good also.
There is a lack of word level Morse training software.
we all know there is much more to learning code than just recognizing
the sounds of individual characters.

"Not enough gap" is a common complaint of ops who haven't thrown away the learning crutch called "Farnsworth".
Not say that it doesn't have its place on the air.
Under poor conditions (such as mostly, now days) a bit of extra space is sometimes helpful, skcc numbers for example.
But very seriously now, wide spacing is a learning tool that students ought to leave behind at some point.
dit spacing is standard; in fact, wider spacing is antagonistic to

[slowspeedwire] Last Telegraph Service in Belgium
Smithsonian.com yesterday published an article stating that telegram service is coming to an end in Belgium.
Obviously not done in Morse or Continental, and not with keys and sounders, but by printer circuits.
More like a "commercial message service" than real telegrams.
For what it's worth...
-- 73 SW & (abram burnett)
Interesting stuff that.
system here in N.Z commenced in 1862, Morse transmission abandoned
about 1963/4, telegrams ceased and telegraph branches closed in
I was fortunate to be able work morse circuits (which were but a shadow of their early traffic handling) from 1952 to 1963.
Ah! The memories.
73, Maurie AK Ofc
In the later years of telegrams in the USA they were all done by Teletype as well.
Only American railroads used manual telegraphy right up until 1963 including when they were serving as Western Union offices in smaller towns.
It was a
shortage of qualified telegraphers rather than better technology that
made the railroads give it up.
Over the years I have come across various sources which have stated the percentage of WU messages handled by teleprinter for that time frame. The first, from 1914, was 20% (said to mostly be by using technology developed by WU's chief engineer John Barclay, better known in the telegraph community for his invention of the Barclay box relay, see this link for that source:
The next was from 1927 and it stated that it was already 75% teleprinter by that time.
The third from an actual WU 1941 typewritten report in the WU files kept in the local history division of the Rochester Public Library stated that it was 95% teleprinter at that time.
The last from a joint book by WU and AT&T celebrating the 100th anniversary of the telegraph in 1944 stated that it was 97% at that time (In that same book AT&T stated that their private line business was 95% teleprinter in 1944 having started at zero in 1918).
Now I am assuming that these numbers all represent percentage of messages handled but the reports were not clear as to exactly what the percentages represented in detail, just whatever percent of the business.
Of course as Tom states, railroads continued to support Morse telegraph and if one dropped into a small town train station before the mid 1960's to send a telegram, it likely would at least be started on its way using Morse Code.
Somewhere I came across a statement that WU dropped their last support for Morse Code in 1966 but the details of where and what were not stated.
73, Chris Hausler
On the Illinois Central, we used the telegraph lines until about 1969 .......
that was mainly because of a bad ice storm which took down the lines, which were not repaired.
still handled WU msgs on the wire in Illinois up until about

cause for concern.
is wasn't for the ARRL, there might not be any amateur radio today;
certainly not to the extent we have it.
If the ARRL turns starts operating like a 3rd world dictatorship, the future of amateur radio is very bleak indeed.
The real question is this: "Do hams really care?"
Most of us want to enjoy our hobby without drama.
However, the ARRL is important to both members and non-members alike.
It is viewed by important agencies, such as the FCC, as the de facto representative of the Amateur Radio Community.
These incidents should be a big wake-up call to SKCC members and CW operators.
The future of your operating interests lie in the hands of a few elected ARRL representatives.
