Morse was prominently featured in the movie "Lincoln." The operators listened to the clicks of the sounders (no tone). I assume that it would have been "American" Morse rather than International.

According to the ARRL:

Producer Steven Spielberg has used Amateur Radio or Morse code in three of his last four movies: Super 8 (2011), The Adventures of Tintin (2011) and Lincoln (2012). Members of the Morse Telegraph Club (MTC) -- an association of retired railroad and commercial telegraphers, historians, radio amateurs and others with an interest in the history and traditions of telegraphy and the telegraph industry -- played an integral part in the production of Lincoln.

According to International President of the Morse Telegraph Club James Wades, WB8SIW, several MTC members -- including Tom Perera, W1TP; Derek Cohn, WB0TUA; Kevin Saville, N7JKD, and Roger Reinke -- provided telegraph instruments to equip the 16 operating positions portrayed at the War Department set. Jim Wilson, K4BAV, and his son Matt had roles as extras. Wilson also worked with production staff and the actors to explain telegraph technology and the role of the telegrapher in the 1860s.

Most excellent!

And it's not just the movies. In the musical "Titanic", there is a bit of Morse, in the song "Proposal/The Night Was Alive".

The "Proposal" part is sung by Barrett, who left his home and his girl to go to sea, because being a stoker on a ship was a better job that working in the pit (coal mine). The "Night Was Alive" part is sung by Harold Bride, the Marconi operator who sends the message free of charge for Barrett.

I still remember the first time I heard it, and wondering if anyone else in the theatre could read the Morse.

RG-213 is also no longer a military designation. The RG series has not been mil spec for more than 35 years.

Me 3. Just to reserve my ability to get on these bands.  Don't know if Pubic Service Electric and Gas uses these bands or not...
I'm located within 1km of Atlantic Electric, PSE&G and JCP&L services. But these utilities are underground. I suspect none are using PLC.

My recommendation would be a 60-foot crank up tower with a HAM-IV rotor and 3 element 10/15/20 meter Yagi on top. Add a 80/40 meter trapped inverted-V supported from near the top of the tower with legs running out to the ground level.

Now you might have to scale back some depending on your situation and finances.

From http://www.arrl.org/fcc-license-counts

the number of current unexpired FCC issued amateur licenses held by individuals on September 22, 2017 was:

Novice:                  9,268      (1.2%)
Technician          374,527     (50.3%)
Technician Plus             0      (0.0%)
General              173,539     (23.3%)
Advanced             42,871       (5.8%)
Extra                  144,652     (19.4%)

Total                 744,857


Percentages may not add up to exactly 100.0% due to rounding.

No new Novice or Advanced licenses have been issued since April 2000. However, the totals for those classes may sometimes show an increase over prior numbers due to renewals in the grace period.

This is a new all-time high record.

Use mineral oil. It was recommended by Heathkit for their original Cantenna dummy load. Mineral oil is available on line and at most drug stores.

Yes, if you can't get transformer oil, use mineral oil. The Heathkit manual makes it very clear that motor oil is not to be used.

From Page 9 of the manual:

"If transformer oil is not available, mineral oil may be used, but do not use any type of motor oil. The vaporizing temperature of motor oil is too low and would cause excess vapor."

The underlining of "do not" is from the manual. Heath was pretty specific - they knew what they were talking about.

Besides.....think about the reaction at the drug store checkout when you show up with a whole gallon of mineral oil.....and tell them you need it for "a special project".

---

btw - you can't use just any Carborundum-type resistor in an oil-cooled dummy load. The resistor used by Heathkit is a special coated type . Without the coating, the oil eventually seeps into the resistor and changes the resistance value. Not good.


The modern part number (made by Kanthal Globar) is 886-SP-500-K. The SP denotes the special coating, which is important.

MFJ also sells the resistor, as their p/n 115-1500A. The A denotes the special coating.

Thank you all for your very helpful advice.  Looking over my options, I think the best solution is to spend the bucks and buy a remote antenna tuner.  I can mount it onto a post outside at the house entry point where I can place a ground rod (tie that to the nearby service panel as well).   Hook up the ladderline to the tuner via a current balun and then not sweat the minor loss of running 40' of coax from tuner to the shack desk.

I may be old fashion, but I would like to have an editor that I can enter, edit, save and view arduino sketches on my laptop without the requirement of loading the Arduino software on my laptop.

I would then desire to be able to later transfer the sketch file to my home computer that I use for compiling, etc at a later time.

Is there software available to view sch files?

I am a novice when it comes to the use of arduino and don't want it on my work computer. Thanks, Stan AK0b

Another tip is this:
