LAVINA;
YOU POSSIBLY REMEMBER THIS LOCATION IN PARIS AND ALSO REMEMBER ALL THE
TRAINS GOING THRU PARIS,ONTARIO WHEN YOU LIVED THERE ??
I HAVE A BEAUTIFUL PICTURE OF THE CNR 6167 - TAKEN IN TORONTO YARD AND USE IT ON
MY COMPUTER AS A “SCREEN SAVER”.

In her last years the CNR 6167 steam engine was used exclusively for CNR Passenger excursions in Eastern Canada.
I believe CNR Tower Paris Junction was still in use and the dividing point between the LONDON EAST & LONDON WEST Train DISPATCHERS BOARD IN LONDON’ONTARIO in September 1963.
CNR 6167 has been preserved and is roosting at Guelph,Ontario

Hello, i found nice pictures of the CNR 6167 on

B&O RR telegraph video
Hi All,
Apparently the B&O Railroad museum has a TV "network". Who knew?
Anyway, I came across the following six minute video you might enjoy:
https://www.youtube.com/watch?v=7Qh4F6xC6W0
It mentions the life of a Woman telegraph operator Abbie Vaughn.
The video is about half commercials but interesting none the less.

AARRGGH!!! What is that CW tone code doing in there?
Surely someone responsible should have known better.

I can assure you, loss is something "all" antenna systems have.
It's only stupid if you don't know how to correct it.
I can also assure you there are no resistors in the matching transformer of the QUAD or the 10/20/40 multiband antenna by LnR Precision.
There is no mystery here.
It is a step up transformer with compensation across the input.
Simple
dimple and danged efficient.
Most EFHW designs place a capacitor on the antenna side of the matching
transformer, then it's tuned to resonate at one frequency.
The EF-10/20/40 has no resonant tank circuit on the antenna side.
We use a 150 pF capacitor across the coaxial 50 ohm side.
Old
school stuff from a very knowledgeable designer.
If you are really interested in learning the magic of the
antennas, by all means contact me off list.
I love those types of discussions.
If you want to see what other knowledgeable folks have done to "unwrap" our antennas it can easily be found on the web.
This
is one of my favorites:
http://www.hamradio.me/antennas/lnr-precision-ef-102040mkii-examination.html
He
does a great job of demystifying the antenna.
But make no mistake, the losses are very low and much more acceptable than a
multiband current fed dipole using a single coax feed and a tuner.

PS: Just for the record our web site doesn't say: Pwer Handling: 200W
SSB/ CW 50W A.Mo"
It states: "Power Handling: 200W SSB/CW 50W A.M."

Experience
My take on antennas after 58 years on the air is that if you can get some metal up in the air and make your rig happy with it, you'll make contacts.

BTW, our pal Steve - W1SFR has spent several years behind bars.
Well,
to make Torsion Bar Keys I mean, ;-).
Steve's latest creation, the Torsion Bar Portable Key, is built around an
innovative short torsion bar mechanism and has an elegant design.
Have
a look here:

Want to be one of the happy few owning a TBP key?
Drop
Steve an email:

Well
done Steve, keep up the good work!
Have a nice day gents, BCNU.
