Fringe TV http://www.fox.com/fringe/ The "Fringe" TV Series http://en.wikipedia.org/wiki/Fringe_%28TV_series%29 ~ RHF . It seems like they added some distortion to the audio in the numbers broadcast. They don't want to lose any viewers to shortwave radio. Jim Fun to catalog the technical errors ... like Peter removing a transistor from the PCB without desoldering it ... or the soldering torch that the shape-shifter used to insert it in the first place, which curiously made a whirring sound like a drill! Also the private pilot talking to a tower on an HF frequency, and in AM mode no less ... wasn't all that decommissioned ages ago? Actually, no. Ok, but then the HF aero comms were all USB, and the numbers station was tuned in AM mode. The pilot never changed modes on his receiver ... HF aero comms are not all USB. Some are. Most are still AM. This is due to the ability of AM signals of very low level to be noticed while other comms are taking place, facilitating discovery in an emergency when conditions are less than ideal. Where are there any AM aero comms on HF? VHF and UHF, yes, but I haven't heard any AM aero comms in, well, as long as I can remember, if ever. International, especially over an ocean, require greater range than V/U can deliver. Yeah, I've never heard anything but SSB aero comms. I hear about as much AM as SSB. What freqs are you hearing this AM on? I'll write them down the next time I bring one up. I usually roll a recording at the time, as well, so I'll save it for you. ![]() |
