<p>The car transmitter guy here…</p><p>The Scosche FMFreq has a couple of model numbers.</p><p>The current model on Scosche’s website, the FMTD10 has a 3.5mm input, so any 3.5mm male to male audio cable will work. I bought mine on eBay for about a third of or half the retail price, but there’s not many left.</p><p>The old model FMTD8R, which…[Read more]
There’s been a lot of people moving in across the street from my house at this new apartment complex, so maybe you can ask if they’re at a place called Woodfalls. Those apartments, plus the train tracks and an assisted living facility are probably the extent of my range on AM and FM.
As I also work part time at our town’s locally owned AM/FM stations, the power to those were knocked off before the tornado sirens went off, but came back around dawn, a little bit after I got my Part 15 stations back on, so there was no “all hands on deck” situation like some of the Nashville or Cookeville stations.
As some of you may know, my station studios (a.k.a. my house) are near the path of the tornado that wrecked a few counties in Middle Tennessee last week.
Thankfully, with a tornado siren literally in my backyard, I was able to get everything powered down before the main event, which went by about a mile away from me, but still did a fair amount…[Read more]
Over the past few months, I’ve picked up a few more FM transmitters originally designed for cars without 3.5mm audio input/aux in jacks.
Here’s how much max range I got out of them:
Belkin Tunecast Auto Universal FM TX – 50 feet
Griffin iTrip Universal FM TX – 25 feet
Auvio Universal FM TX – 50 feet
and the big winner was the Scosche FMFreq…[Read more]
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?
