Dayton FAM-3 Frequency Agile Modulator 3 Channel

The reason I purchased this item was I have two different SAT receivers and a VCR I wanted to broadcast (all turned on and available on UHF channels 40, 50, and 60) to several (6) TVs from a central location in addition to the local OTA HDTV and SDTV channels (through the CHANNEL PLUS 2512 2-WAY SPLITTER/COMBINER) from an outside antenna. One of the SAT receivers does not have its own audio gain control making it unbearable when switching it on. By using the audio gain control on the Agile Modulator I was able to adjust the sound to a normal level. I have used this item for about two and half years now with no problems except for having to replace the anemic audio gain control POT with a plastic encased version.
