Thew exact RF range depends on the tuner and if you get a device with the R820T tuner it will work down to 24 MHz or so.

Re: [Discuss-gnuradio] 49MHz Rtl_sdr receiver
The simplest solution might be to transvert using something like the ham-it-up. When not doing wireless mic duty, you'll also have a general coverage receiver to tinker with.

[Discuss-gnuradio] 49MHz Rtl_sdr receiver
Hello list; I have been following a thread by Marcus and others about coherent receivers, etc. I have a question: Is it possible to change the clock frequency to receive a slightly lower frequency? I have some ~ 49.89MHz wireless mic's that I would like to reuse, and an SDR seems like a cool solution. My current RTL dongle bottoms out at exactly 50MHz L Can I just change the clock or are their firmware issues as well? Right now if a try and set the frequency to say 45MHz, I get a "device not found" error from the Windoze software.
