137kHz QRSS3 test

One of the aims for this week is to carry out that 137kHz QRSS3 test with my earth-electrode "antenna" in the ground with my FT817, E-field mag-mount on the car roof and SpectrumView software on my iPhone. To do this needs the coax fitting to my mag-mount. I must have "stolen" it for some reason.

Before going out in the car I can check things locally.

This software allows about 2 minutes of audio to be recorded as a spectrogram view. I hope to do this by just placing the iPhone next to the FT817's speaker. The photo of the SpectrumView screen is attached.

2200m beacon

My test a year ago with this was (surprisingly) a failure. At some point I would like to try again. There is a short video of this beacon on my video channel. It sends CW at 10wpm and QRSS3.
