[slowspeedwire] How Did Edison Sine?
Does anyone know how Thomas Edison sined?
(Another question I never thought to ask Stu Davis...)
-- 73 SW & (abram burnett)
This is a good question.
Need to dig up some old train order o r similar document from his railroading days
Whatever Edison sined could not be determined by finding a train order............
because Sines were not permitted on train order records, only full names, or actual initials.
The documents necessary would be messages he copied, or relay office records of messages sent to stations where he was working.

[skcc] MRD - Maritime Radio Day - Announcement: 14 April 1200Z to 15 April 2200Z
idea of this activity is to get former professional radiotelegraphers on the
air and for others to work them.
You're certainly welcome to work the girls and guys who worked at various coast stations, aircraft or ships.
Maybe when we are all dead, the event can be modified.
But right now it's very exciting to work the genuine article.
Listen to the fists, there will be some clunkers, but you will hear some fists that are of the finest kind.
73, David N1EA ex Tuckerton Radio/WSC, ex many merchant ships.

knows what will be the propagation condx, so for long distance contacts and to
give everyone a fair chance of having DX QSOes during the Event and because
14052 kHz is the most common calling QRG, it is suggested to DX and QRP
stations to operate inside a small band from 14055 to 14058 kHz .
It is also suggested to avoid calling CQ in "Contest Mode",
PLS give adequate time for weaker stations to be heard.
please use the above suggested band as Watching Band reserved to radio stations
from far distances.
IF INTERCONTINENTAL CONTACTS ARE NOT PERMITTED DUE OF PROPAGATION CONDITION PLEASE RUN THE MARITIME RADIO DAY WITHIN RADIO STATIONS OF YOUR SAME AREA AND DON'T FORGET TO SEND THE LOG AT THE END OF THE EVENT, IT IS NOT IMPORTANT THAT U.S.A. OR VK/ZL STATIONS MUST TO ENTER IN CONTACT WITH EUROPE OR OTHER DX PARTS OF THE WOLRD, MARITIME RADIO DAY IS DEDICATED TO ALL FORMER R/O's EVERYWHERE TO REMEMBER THE " GOOG OLD DAYS" OF MARITIME RADIO COMMUNICATIONS.

Best regards, MRD Staff
The Morse Telegraph Club will be celebrating Morse Day on Saturday, April 28th at the Wabash Depot in Ferguson, MO. By my count, this is approximately the 17th year we've celebrated Morse Day there.
Hard to believe we have kept it going so long!
I will have a display of antique telegraph instruments and we will be on the wire as usual.
If you are in the area (and even if you aren't), please come by the depot, have lunch with us, and enjoy some friendship with the gang.
I will also have an all caps Western Union Mill typewriter if you want to try your hand at banging out a telegram on an all caps mechanical machine!
Here's the address:

I looked on the Reverse Beacon Network (RBN) for responses to AA7FV CQ calls during the USA SSN last Thursday evening (=Friday UTC).
includes both 40m responses (orange lines) and 30m responses (red lines).
It covers the period from 0000 UTC to 0043 UTC, with the change from 40m to 30m at 0027 UTC
I think it indicates better overall coverage on 30m, although from Arizona to the Northwest USA evidently 40m was better.
There don't seem to be any RBN reports on either band of Arizona being heard in Texas.
was only one report from Europe (EA5WU on 30m).
Just for possible interest.
Cheers, Darrel, aa7fv.
The April 5 report from Dr. Tamitha Skov:
The bright region that was once 2703 remains visible and it still shows signs
of life, but solar flux remains at solar minimum conditions. This is bad news
for amateur radio operators and emergency responders, who were hoping for
better radio propagation...."
Cheers, Darrel, aa7fv
From Cootie lover, Mike Pilgrim, K5MP.
Let's begin by describing “What is a “cootie key”, as follows: Some of the other names for a cootie key might be more familiar– sideswiper, doublespeed key, and slap key.
The simplest definition is a double-sided straight key, operated horizontally.
Around 1910, during the heyday of manual telegraphy, it was common for telegraphers to spend entire shifts either sending or receiving, often at the same speed and with the same operator on the other end of the line.
The incidence of RSI ( http://en.wikipedia.org/wiki/ Repetitive_strain_injury ) or “glass fist” became a serious,,,see editor's remark
The solution was to eliminate the vertical motion of the wrist typical of straight key operation and replace it with a horizontal movement of the entire hand.
The two devices developed with this in mind were the “bug” or semi-automatic key, and the “cootie key.”
Both feature a horizontal motion in which the lever is held (not tapped).
The thumb and fingers do not flex and the hand is rocked back and forth on the “heel” of the palm.
Since there is no flexing of fingers or wrist, there is very little chance of RSI. The cootie key consists of a single lever which can be swung back and forth between two contacts, either of which will close the circuit like a straight key. Thus the return stroke of a dot or a dash can become the stroke of the following element, almost doubling the speed of operation. You start each character on one side, and each subsequent dot or dash is made on the opposite side, in a back and forth motion.
If you’d like more information about using a cootie key, read Jerry Bartachek’s “The Art of Side-Swipery.”
A cootie key can easily be made using a hacksaw blade.
Bugs were very expensive by comparison, so most cootie keys were home-made.
The few commercial cootie keys were also relatively expensive and with a few exceptions are very hard to find today.
