As the was raging this morning 1400 UTC 10:00 EDT, this was me waving Goodbye to the 20 meter band this as my beacon showed fading band propagation.

And 20m went KAPUT. I've succumbed to Mother Nature's . Running 20m simultaneously with to see what pans out on this activation.

Who's Afraid of the Big Bad Wolf? Not me! These are the tools I'm throwing at the BIG BAD for this morning's activation. A for , for & for . EXPERIMENTATION is the foundation on which was built.

Another day another different antenna. 40/20 meter built specially for my 40 & 20 meter . Couldn't break through activity effecting so tried some on 40 meters

Update: My transmitter v1 looks great! PCBs from JLCPCB arrived some days ago and I soldered the first kit. Works well but some changes will be made to v2 of the PCB. Upcoming: measuring and testing.

Do you think we've had enough closed, irreproducible, proprietary digital modes contaminating the hobby (, , , , , etc.)? Well, now we've got for .

No: ham radio should be based on open, free standards. There are plenty of free, open, well documented digital modes (, , , , , , ) in addition to the oldest-ever digital mode (). Please support ways of operation everyone can inspect, modify, or build a radio around.

And we are having another go at overnight operations of our student built beacon callsign DL0WH - this time with an improvised antenna tuner adjusted for maximum field strength in the near field using . First few transmission cycles are already looking pretty good.

I’ll put mine on the air tonight! Woohoo! Been handing out points the past few days.

For all operators in the Midwest, keep an ear out for DL0WH on 40m. @quantensalat is a physics teacher who built a WSPR station with his class. It would be so awesome for the kids to hear reception reports from real live people.
Tune to 40m overnight, and let’s see if we can give them reports!

student project update: it works!!!

After some modification to the amplifier, the oscillation has been suppressed enough. The dipole had to be shortened 15% or so due to the proximity to ground and buildings but no matter, the system works.

We got immediate spots in Great Britain on our first transmission cycle - in broad daylight @ 40m using our club call sign.

The dipole has a metal facade directly to the east, which might explain the directionality of the spots

Student project update: Today we let the student built beacon operate through the night for the first time using our club call sign, and it is fascinating to see places open up during dusk.
Yet, since our dipole mainly shoots west, eastern europe and russia only came on the map slowly while La Palma appeared relatively early

The second night of yielded much the same picture with one very notable exception: we managed to be heard in Costa Rica

@quantensalat okay. I will run starting Sunday night EDT. I’ll leave it on until Wednesday. I am KB8QPT. Is this for a school?

@quantensalat

As soon as the storms pass today, I will turn my on.

I heard my old hometown (santa paula, ca) on last night!
