UPDATE: After using the Insignia Universal FM Transmitter to broadcast some softball games live, my initial assessment was ironically enough “in the ballpark”…the signal dies at the outfield fences, which are about 200 to 220 feet away from home plate, then adding in about 20 feet from the press box to home plate, the maximum range in any…[Read more]
I have two AM/FM/SW receivers at my disposal, one analog (Kaito WRX911) and one digital (Radio Shack 2000669), so that’s what I’ve been using to monitor my Talking House AM Transmitter and my assortment of FM transmitters originally designed for use inside cars. They’re not the best receivers, but not the worst either, but pick up my signals…[Read more]
So the Insignia Universal FM Transmitter arrived sooner than I thought it would, so I have some test results from the home studio.
Currently the Edirol UA-3FX USB Interface is feeding audio to the Insignia, and the Edirol UA-3FX is being used as the sound card for a Dell Latitude D630 laptop that has Winamp running RFCC-Lebanon’s automation.
I’ve just ordered the Insignia Universal FM Transmitter. It’ll be at the RFCC-Lebanon studios before the end of the month.
This transmitter is FCC Part 15 Certified with the FCCID being 2AEI7M35.
This transmitter, like the Prime Audio Wireless FM Transmitter and the Scosche TuneIt, has an 1/8″ jack (3.5mm) for taking in audio from anything that…[Read more]
Actually, the Scosche TuneIt and the Prime Audio I have both have a range of about 100 or so feet without fading and they fade out completely around 200 to 250 feet depending on the terrain, with no modifications. I’ve posted about them a while back. The Prime Audio can work off a 12V AC Wall Adapter, and the Scosche can work off any adapter that…[Read more]
The Rolls website says that the HR70 has a transmitter output power of 40 milliwatts, antenna impedance of 75 ohms, and 150 milliamps of current.
Can any of that data be used to determine if the field strength of this transmitter is under 250 microvolts per meter?
Like I said in my earlier post, the “van” is just there to get me from my home studio to the gym or the field. My setup includes the following:
** Laptop with Windows 7 Operating System (Switching to a tablet with an Android 5.0 Operating System by the end of the year)
** USB Audio Interface (My main one is the Behringer Xeynx 302USB but I use…[Read more]
I guess what I’ve been doing the past couple of years for ball games is “portable Part 15″…I’ve taken my TH 2.0 for AM broadcasts and my Prime Audio “Wireless” Transmitter (that’s what they have printed on the manual) or my Scosche TuneIt for FM broadcasts. My “mobile vehicle only gets me to and from games. Sounds like the station van guy has to…[Read more]
Yep, straight out the box, and with one of those cigarette plug to AC wall adapters to power the Scosche, it was good to go. The Prime Audio came with its own cig plug, but it and the Belkin Tunecast II can be powered by a standard AC wall adapter. The Tunecast II has to be powered exactly with a 12 VDC/200 mA adapter, while the Prime Audio can…[Read more]
In the spring, I threw the idea out on the P15 forums here and on Facebook of using FM transmitters made for use in cars as Part 15 FM transmitters.
I’ve been using the Scosche TuneIt for about a month or so on 101.7 and it has range of about 250-300 feet in any direction with no problems so I’m definitely going to bring the TuneIt with me to…[Read more]
