Markus123456 has a spectrum analyzer and I sure when he has time he will try it out.
I am really interested in the board. I have a few modules myself and i would love to put them on my smaller planes. 15grams plus a light weight camera and all up I would add very little weight. I hope for under 30 grams with an e-osd. I would put a rp-sma because I have so much damn rp cable
Sounds like a great dyi project and if you need someone to test your board (I'll use my modules etc) just let me know.
thanks for the tip on tuning too. I am going to try that with a few helicals I have!
