Found in the Attic: LPB Carrier Current AM Transmitter

By Tom Vernon on Feb 12, 2014 2:21:00 PM

LPB carrier current transmitterAn often-overlooked facet of AM broadcasting is carrier current radio. Typically carrier current is implemented by feeding the RF signal into the AC power distribution system of building allowing for broadcasting over limited areas. Hence, its widespread use among student-run college radio stations.

This month's trip to the attic turned up a dusty but functional LPB RC-6A carrier current transmitter, along with its coupler and test gear.

Five things your competition is doing to sound better than you

By Denny Sanders on Dec 21, 2011 4:12:00 AM

1) Their source material – songs – are technically perfect

Garbage in – garbage out; especially true when playing your music through a modern, hard-working audio processor. Stations that sound great play music that sounds great. This means the source material is as close to perfect as possible. No MP3s. No downloading songs using BitTorrent. With the cost of hard drive storage being so low these days, there’s no excuse for not ripping and storing your music library in a linear format – no bit-rate-reduction (data compression). If you must obtain data-compressed music, be sure it’s at a high bit rate. 256kbps minimum for AAC; 384 kbps minimum for MPEG Layer II. Check your songs for full frequency response using spectral analysis; you can connect a PC with a good sound card to your console output and watch for songs limited to 15kHz or less. Replace these cuts as you can. YOU are the final gatekeeper of your station’s source material integrity.
