>Perhaps a 2 meters whip is a bit too short ?
The smallest antenna that I have experimented with was a base loaded vertical that was almost 3 meters long and I observed reasonable success with about 100w TPO. The radiator was a 2 cm diameter aluminum antenna tube so charge was distributed pretty well and no corona was observed. There was no additional top loading in the test. I was using a fair radial system at the time but perhaps its time to try this same arrangement in a fixed mobile setting as you have done here.
I look forward to hearing about your further experimentation. I hope you will conduct this test again in the winter.

I am sad about my experiment, only one station copied my very loud signal last night : F5WK at 72 km. Perhaps a 2 meters whip is a bit too short ?
For a next experiment, F6GEX just give me an other mobile antenna shape idea. Intesresting indeed ! Be sure, I’ll give to you also the results of the doppler effect. HI.
Best 73 de Andy F6CNI.
Great Andy, this is a wonderful experiment!
If you could persuade yourself to drive on a highway while transmitting, would we be able to measure your speed using Doppler effect? Probably not using WSPR, but surely with QRSS-60...
73, Markus (DF6NM)

Hi to all.
I’ll be testing this evening WSPR 2 and at times WSPR 15 on MF using a short mobile antenna. My call be F6CNI/M.
Of course, I don’t drive my car, it is resting in my garden…
Reports be appreciated.
Begining the experiment this evening at 2000 TU to next morning, but I think the best period is around 2300 to 0200 TU.
