FM passive radars as alternatives to Graves

Two weeks ago, on November 13, I left my computer logging meteors on Graves' frequency with the help of Baudmeteors. My goal was to catch the Leonids shower. But on November 15, around 16:40 UTC I detected one meteor and then, only silence for the next two days. Graves was turned off.

You don't realize how dependent the radio meteor detection is from Graves until you lost it. Around 20 UTC I realized there was no problem with my radio or just a very low meteor count. Graves were really off!

Baudmeteors: Capturing meteors with Baudline

I already knew Baudline. I used it some years ago as a simple FFT spectrum display but I didn't use it until last summer, when Iban, EB3FRN sent me a little script to automate meteor capture using Baudline. It turned out Baudline was much more than a simple spectrum analyzer display. Baudline turns out to be a powerful signal analyzer and quickly it becomes one of the most used programs in my computer.

Impressive "dual band" feed

This weekend I've reviewing some photos taken last summer, and I found this interesting photo from an interesting dual band feed for parabolic dishes:
