Question: To someone who actually owns this please: can it be set to 87.9?  Many home transmitters can even though the printed specs say they can't.  Thank you.
Document: They warn you not to use this supply on other items or any other supply with the phone. I assume they are telling the truth so I have not tested this.Left handed antenna connector, making it difficult to fabricate your own (illegal) antenna.It only goes down as far as 88.0 and not 87.9; unfortunate since it is wide open in many areas.What I have no opinion on:I have only used this as a home transmitter. It sits on a shelf and is remotely powered on and off.
I have mine connected to my mac mini. Whether the transmitter is on or not, there is some radio interference (caused presumably by bad shielding) in the speakers connected to the other audio output. If you pull one end of the audio cable out the interference goes away. Another problem is hum. If you power the unit by any means other than batteries, you get varying amounts of hum in the signal, even when you're careful to keep the signal cable away from power cables.Must say that Whole House Transmitter are certainly good at marketing.
I have owned different FM transmitters in the past and none of them performed as well as they were advertised. I can plug this one into my computer and then listen to internet radio on any FM radio in the house or even out in the garage. It sounds as if I am listening to a local FM radio station. I am truly amazed at the transmitter's performance. I highly recommend this product to anyone. It will be nice this summer when having bar-b-ques out on the patio.
Ding dong, and the doorbell rings, package at front door. Connect it up in about 5 minutes, turn on radio & transmitter. Well, all I can say is that it works like advertised. I found a clear spot and easily set the frequency to match. The sound is clear, slightly lower volume than other real FM stations (about 3db lower), which is no problem.Then I got into the automobile and drove around the 2 blocks nearby. I could hear the transmission quite well strongly a block away.
To do this, you hold the cycle button and mute and it goes into high power mode, shown by a lightning bolt on display. I have not tested this since I don't need extra power.What I don't like:Per my oscilloscope, built in AGC that is supposed to avoid over-modulation does not work.Front panel meter shows volume, not modulation. This is misleading at best.Per the instructions, the power supply is not standard even though it looks like the same one as my Droid smart phone.
OK - I just got this today and set it up, so maybe I shouldn't be writing this so soon.The problem I have is we live in the boonies. The few radio stations we get are weak, the selection of music types is obviously poor and the reception is spotty & unreliable at best. As part of our DirectTV package, we have music, but that is restricted to our home stereo. What to do?I bought this unit to transmit our DirectTV music throughout our home. Setup was easy and the signal is strong throughout the house.
Even with having a gift card I was skeptical with the price point. I was looking for a whole house music system and tried Bluetooth speakers. Problem was, when one speaker was on the other would turn off.I bought the fm transmitter to connect them all together. Worked like a charm once I found the proper station. I had 3 speakers and 2 radios connected on different levels of the house. I even had reception in my car driving around the block. Definitely worth it for my home entertainment project.
It seems to work fine but the device feels cheap and fragile. It's powered with a mini usb connection that connects to what appears to be an ultra cheap usb power connector. The cord and the power adapter don't even connect properly as the usb cord only inserts approximately halfway into the power adapter before coming to a stop. Feels like a 30 dollar product...The unit is light weight and if you don't care about breaking it, probably great for portable use. I wouldn't touch it for anything else though. The cheap 60 dollar units from china feel sturdy compared to this product.As far as transmission strength and quality goes, it works fine and the sound is acceptable.
Has license info on transmitter. Good to know if you worry about getting busted for running an unlicensed station.Decent sound for an inexpensive transmitter.Reasonably easy to set up (but you must be careful not to over-modulate).Decent range. With the antenna perhaps 10 feet above the ground, it is reliably reaching 150 feet.Has selectable pre-emph curves, so you can use 75 microseconds in the US or 50 in Europe. Most cheap transmitters use 50 microseconds, which sounds very dull on US radios.Comes with both legal and illegal antennas; I assume the illegal one has better range (I haven't tried it since I am satisfied with the current range) if you don't mind risking getting busted.You can turn on Hi Power Mode (again, you will not be FCC type 15 compliant; fine if you don't worry  about getting busted.)
I had the Gold Edition for about 5 years, and it was beginning to show its age, so stumped up for the new version. First impressions was how cheap it feels. I attached the stub antenna, but when I went to remove it to attach the wire antenna instead, I found the stub was stuck on.The unit does come with a plethora of accessories, including a microphone - not sure what that's for, unless you want to start your own pirate radio station!Nice that you get a number of presets, and that the entire FM band is available, not just a few channels at the upper end, like with the Gold edition.Sound is fine, not sure about some of the other reviewer's experiences of low volume, if you set the unit up correctly and the volume on your device, you should get adequate levels.I do have some niggles, though.
Answer: I just tried and it looks like the lowest it goes is 88.0. Sorry.
