Morse Code / Re: QRP DX
Last post by RadioRay - March 10, 2023, 10:19:36 PM
Good question.  The comms begins with propagation first.  The easiest antenna length does no god, if the band is too high for your regional comms/NVIS.  80 meters is a real work horse for regional comms.  The great news is that stringing a 130'ish foot piece of wire at low height is easy. Remember that for local comms having the antenna up a bit over head height is a good start.  Any EASY elevation after that helps, but is generally not essential.  I've done a lot of outdoor/wilderness radio and mil radio opns, where a bit over head height was what was practical.  That's not good for long rages, like a thousand miles or more, but fine for regional/high take-off angle work.

I'd recommend either a simple dipole cut to frequency BEFORE you deploy or Gil's favorite , the End Fed Half Wave wire.  The EFHW is usually easier to deploy and retrieve, especially in trees.

CW DX!  Definitely,  A little wire and Morse code is amazing.  I just had a basic QSO with a fellow in Germany on forty meters using my QRP rig, maybe five Watts. and a dipole up only 30 feet. It would have been better to have the dipole at 60 feet for that long haul, but he and I talked for about 15 minutes in slow, handsent Morse/CW, so it was still working - even at QRP levels.

Please let us know how things are going for your radio excursions./

Thank You, Sparks !

People who think radio is obsolete are ignorant. They see it as comparing a row boat to a ship.  When a mighty ship sinks, the lowly rowboat becomes King.

For those who thought HF and MF can be scrapped and replaced entirely by satellite, you can read here what happened when one of the major providers of satellite service was hacked the day Russia attacked Ukraine in February 2022:

Google Translate will do a decent job here if you don't read Norwegian.

A couple of background links about the break of communications:

Thanks Marjamada.
Unfortunately the forum has fallen into disuse.
Hopefully that will change. Thank you for your post.
