I have a Sennheiser cordless headphone transmitter, a couple of half decent speakers and an amp. What I want is a receiver so I can have the speakers at the other end of the room without any cables. I don´t want a Sonos rig and I can´t use the speakers with a Bluetooth unless of course there´s a B´tooth receiver and I haven´t found one . Any ideas anyone?

Why do you want to operate at less than 1 Hz?

843 millihertz is not RF, it's just nervous DC! (rimshot)

I don´t understand any of this so I´ll say goodbye.
Nunchuks, or "danger sticks", are weapons used in martial arts. I have no skill with them and would probably hurt myself if I tried to pretend that I did have any skill with them.

one way would be to use a uhf tuner from a tv with a scanner connected to the if output.

Didn't they chop off the upper end of the UHF band for cellphone use prior to the digital changeover in 2009?

I checked, and it is channel 74, so you'd need a pretty old TV to make it work.

my tv's go to the top of uhf and some beyond. a tv made for cable tv should go that high. I have a uhf tv tuner in my home made spectrum analyzer that goes up to over 1000 mhz. got it from radio shack years ago. there are tv tuners available of all kinds.

Yes, but you may very well find that anything built in the last 35 years may not cover the specific frequency of 830-836 MHz.. The cellphone companies have been very successful in preventing the construction of receivers for their spectrum.
