Radio Frequency URI
Friday, September 30, 2011 by darcoOver the past few weeks, I've been thinking that it would be useful to have a URI format for describing a radio frequency or channel. Such a URI scheme would be useful for hyperlinking to a specific frequency from a link and for exchanging radio frequency lists between devices, programs, and people. (Think QR-codes)
I looked around to see if such a URI scheme had been developed, but I couldn't find anything. Since I think such a scheme would be useful, and I would like to use such a scheme in the future, I decided to go ahead and throw together an informal proposal for what such a scheme would look like and how it would work.
For now the scheme identifier is " UPDATE: (2014-01-08) According to RFC6648, the practice of prefixing "experimental" protocol identifiers with "x-freq
" because it is experimental at this point. If this scheme is ever formalized into a real standard then the "x-
" prefix would be dropped.x-
" is now deprecated. As such, you should just use "freq
" as the scheme identifier instead of "x-freq
".
Here are the use cases that I would like to be able to specify this this URI scheme, along with some examples:
- A specific single frequency.
Ex: <freq:107.9m> - A frequency with a repeater input shift.
Ex: <freq:145.23m-0.6> - Split receive and transmit frequencies.
Ex: <freq:145.93m/435.75> - Modulation type and other parameters.
Ex: <freq:145.23m-0.6?m=fm;dv=5;ts=100>
