Speaking of the old Baltimore & Ohio Railroad here's,,,,,,,,,
a current Facebook video of the bridge over the Wabash River on the former B&O line between Decatur, IL and Cincinnati, Ohio.
It was taken using a drone and it opens with a view heading westward from the Montezuma, Indiana end of the bridge towards Hillsdale, Indiana where I worked at the tower in 1954.
The rails have been removed from the ties.
I saw many, many heavy freights heading eastward at Hillsdale towards this bridge.
It's
a shame they tore up the rails between Hillsdale and Indianapolis (maybe east
of Indianapolis, I don't know).

SO2R & Flexradio on german keyboard Stereomode (Good to know?)
Hello guys,
i have Flex-6700 and use SO2R with N1MM Plus and german keyboard.
When I want to switch to STEREO Mode (two slices will be ON simultaneously all the time) with Tilde Key it’s not working.
They are not opportunity’s to do this on other keyboard than US.
I should switch in windows to the US keyboard and that klick the same key (tilde) like on US keyboard.
Additional “Config - Sub receiver always ON” not make any different when using N1MM in SO2R and Flexradio.
I would suggest for stereo mode another (international) key on keyboard to use instead of tilde key, or couple the “Config - Sub receiver always ON” in SO2R as Stereo switch.
Can you give me please short feedback or Tipp about this?
Thanks in advance.

Emil,
The stereo keycode is 192.
You can find the key on your keyboard with the Config, Function Keys tab, Keycode of Ins Key box or this webpage. http://www.cambiaresearch.com/articles/15/javascript-char-codes-key-codes <<------ NICE
The Dual RX On issue is that Flex SO2R is a single VFO for each virtual radio.
Sub Receiver Always On works fine in SO2R with a regular radio(s) that is capable.

What Do I Need?
I'm new to Ham and CW.
I have been attempting to use a QRP Pixie with a 40m dipole for CW with sketchy results.
What
is a good choice for a transceiver?
73, Marty KD2JQG
REM :
I always want to have an antenna with multiple band coverage: the more the better.
Multiple
bands means I can always take advantage of the best propagation available at
any given time.
In the simplest case I'd choose an endfed wire over a dipole.
However, it must be cut to optimum length.
And
an antenna tuner is required if it is to cover all the bands.
Here's a good article on endfed wire lengths:
http://udel.edu/~mm/ham/randomWire/
Approx
135' (34.29m) length would be ideal; 72' (18,288m) would be a good shorter
length for multi band coverage.
It's great to have a righ with an auto-tuner.
Yes, a manual tuner only takes a few extra moments to retune to previously logged settings on each band.
But being able to jump instantly from one band to another is so much nicer.
An
auto-tuner will change how you operate compared to using a manual tuner.
Beware: some rigs have very limited antenna tuners, capable of
matching only 3:1 SWR or less.
Other
rigs (K2 and K3 in my experience) can match 10:1 or more, which would be
suitable for an endfed wire.
Power output. I've logged thousands of WSPR contacts trying to
see how much an S-unit on the receiving end is worth in number of contacts.
Results say that each time you double power output you can net 3x more
contacts.
My own setup: K3 @ 100 watts (was 10 watts for a number of years
before I installed the PA module).
Endfed
wire antenna, approx 90' (22.86m) length.
Also, a 10m thru 20m 'cobweb' resonant antenna in the attic.

Actually, 137 feet (34.798m) is better than 135 feet (34.29m).
With a 17 foot (5,1816m) counterpoise.
73 - Bill KA8VIT
REM :
Yes, 135' was approximate.
You'd
want to trim it to best length in your own surroundings.
A nice convenience of an endfed wire is that if you can make some provision for
routing 4 or 5 ft of extra wire on the feed end you can double it back over
itself for various lengths of adjustment.
Then
you never have to drop the far end for trimming; just change the effective
length at the shack end by doubling more or less wire in the feed.

I was encouraged to do it by WB4DBO Bill,,,,,,,,,
So this is my first WES - and after seeing the special MacGyver keymaker bonus I decided that would be a whole lot of fun..
So I made a key and made some contacts and then I had to work...
But
works is slow so I'm posting a photo in the hopes other keymakers post photos
of the keys they made.
Mine is as MacGyver as possible using junk I took out of the trash can beside
my desk.
Cardboard,
foam, a pen, a pop bottle, duct tape, and some wire.
Attached is a thumbnail and a link to full size image.

Key adjusment
Hello
friends,
Very interesting stuff gentlemen, here's my 2 cents on the subject.
When the arm of the key is a flexible blade, contact spacing
depends on blade flexibility: the stiffer the blade, the narrower the contact
spacing.
When the arm of the key is a rigid lever, a return system of the lever is
provided.
This
adjustment determines the rest position of the lever and contact spacing.
I first adjust both tensioners, magnets or springs, with approximately same
amount of tension (weak to moderate) on both sides to achieve a certain
equilibrium position of the lever.
I then temporarily adjust contact spacing to check if the action is good
enough.
If not, I readjust tensioning.
If
the action is smooth and the key produces a nice clickety-clack, I accurately
adjust contact spacing.
I start with a too narrow gap and I increase it equally on both sides until no
more chatter is heard.
I adjust my keys by feel and by ear.
FYI, I accurately measured contact spacing on my TWanger and FM-32, both rigid lever sideswipers, with feeler gauges.
Gaps
on both sides are as follows:
TWanger - (magnetic tensioning: 0.5 mm, 0.020".
FM-32 - mechanical tensioning: 0.4 mm, 0.016".
Thanks folks, have a nice weekend, BCNU.
Happy holidays, season's greetings.
