I need a highpass audio filter for my BM17, Yeasu EQ is not capable of cutting the lower frequencies. MH-31 stock mic is using a simple capacitor for that on switch position 2 (see freq. curve). How is everybody solving this issue? just use a 0.33uF - 1uF cap and a switch?

Guys, please consider contributing however small. This project will just get better and better, I noticed an improvement again yesterday.

I spend ~30€ euro/month to cover the electricity costs of running the rmnoise3.rmnoise.com server, which provides the #RMNoise service to the #hamradio community. If you like the service, please consider making a small donation donorbox.org/rmnoise TU
