Good evening: First and foremost if there is a better forum for this please let me know, this seemed like the best one for regulation questions. I'm working on a project that is kind of a "rf pager". The design is to have a transmitter that will broadcast a status out, likely dtmf tones or similar, to control status lights on a receiver. The purpose is to get my attention when I'm operating a machine where I may not notice the phone buzzing or if I'm in a cell dead spot, of which there are a couple on my property and in nearby parks. For this use the transmitter will be unattended and broadcasting on a timer. This will be a one-way transmission, but will only run on-demand when I need it. The receiver will be monitored, but will only be status lights. My question is how is this classified under the regs. Would this be a beacon? I see 47 CFR § 97.203 allows for one-way transmissions under 100W, but this is not "for the purposes of observation of propagation and reception". Is there another section that allows this kind of transmission I should be looking at?
