Wire antenna question

Ah! Here's a fellow user of #26wire, Paul. If a reasonable catenary is left in the antenna legs, wind doesn't bother such small wire.

Have a look at:

to see the arrangement at radio station VE7AOV.

We've had very high winds, documented on that site, and neither leg has blown down.

    For those who need an antenna that doesn't bother the neighbo(u)rs, consider fine magnet wire like Paul's.

It's only 0.40 of a mm. That's hard to see at any distance.

Loss to resistance from skin effect at h.f. is NOT a problem contrary to what we were told years ago.

With magnet wire, the insulation is bonded to the surface so there's no corrosion surface layer to cause I^R issues.
Neither leg has been lost here in any wind and, as Paul says, the stuff is cheap anyway.

No Micro$oft or Apple products were employed in the production of this email and no horses were injured.

As for the history of the Telegraph

I like the enclosed poem Цcirca 1848 Ц which was inspired by MorseТs invention of the telegram


G.L.ФGrenФ Schrader, Former Order of Railroad Telegraphers (ORT)


The sideswiper was the last key that I learned but along with the semi-automatic key,,,,,,,,,,

it remains my favorite.

In fact when I first heard a sideswiper on the air, I couldn't copy it, but after a minute, I started feeling the rhythm of the code, and it started making sense, as soon as that happened, not only could I read it, but I was hooked, I wanted more and more of this JAZZ.
    That's what sideswipers are - they are the JAZZ of Morse.
N6SL sends Dixieland because of the time he spent in New Orleans, LA where he was one of the premier Morse operators at famous maritime coastal radio stations, Slidell (LA) Radio, WNU, the last remaining station of Tropical Radio Telegraph's network of radio stations.
    Do you think I'm on to something?

Cootie keys are like jazz?

Maybe the French Dyna sings like Edith Piaf singing "Hymne à l'amour"?

You will love our little history section of our web page at:

masterfully edited by Yann, F5LAW, who sends such beautifully clear music with his various sideswiper keys.
