So simple, just plug in, set Freq, and listen.
Today we set the unit up at our church and put a music CD on to play to test the sound. It was GREAT. Our IT guy said he thought he had never heard our sound that good before. After the drive-in services we are going to put it in the Sanctuary on its lowest power setting and use it for the hearing impaired. Ignore the picture above, what was delivered is what was on the product page exactly as described and is a great value. The Seller's service was exceptional when I asked to be sure what they were sending. This Pastor says Thank you!!
Noisy fan but good signal.
For the money I'd say it's a great deal. The supplied power supply is a two prong and thus ungrounded supply which I found produced a 60Hz hum in the background of the transmission. I replaced it with a 3 prong 12DC power supply Kastar AC Adapter, Power Supply 12V 6A 72W, Tip size 5.5*2.5mm for LCD Monitor, LCD TV, 5050 3528 5630 LED Strip Light, Tape Light, Rope Light, Wireless Router, ADSL Cats, Security Camera that solved that problem. The fan is easily 5 times louder and at a much higher pitch than an almost identical 7 Watt unit ( RioRand (TM) Upgraded RR7C+ FM Transmitter Mini Radio Stereo Station PLL LCD with Antenna ). I must have got a lemon but I'm not going to bother to return it just for a bit of noise - but if that would bother you perhaps this one would be better for you: Signstek 0.5 W 05B Dual Mode Long Range Stereo Broadcast Home FM Transmitter with Antenna and Free Audio Cable*Fashion Black* as it is totally silent - it has no fan. I've used the 7 watt since 2015 with no problems and 6 of the 0.5W units since 2016 also with no problems but this unit was ordered on April 28, 2017 so time will tell - I'll update this review if it dies.UPDATE: moved it to the garage with and added a magnet mount car antenna and now I get 15-20 blocks range on only 5 watts! Utterly amazing! I learned two tricks to reduce the volume of the fan - take out your hearing aids and move it to the garage! LOL
Sound quality was good. I have not done any extensive range testing ...
For the most part the transmitter was as advertised. Sound quality was good. I have not done any extensive range testing as I have not built a "real" antenna yet. My plan is to build a nice copper pipe J-Pole.I did make measurements of the transmitter's power output with a Bird Model 43 Watt meter and measured the antenna VSWR with a Bird AT400 antenna analyzer. All power measurements were made with the antenna that was provided attached.Advertised high power: 5.0 to 6.0 WattsMeasured high power: 5.6 Watts (93.7MHz)Advertised low power: 1.0 to 1.5 WattsMeasured low power: Just under 0.5 Watts (93.7MHz)The antenna that was provided works much better than I would have expected -- though performance was greatly improved by adding "tiger tail" (a wire that runs at a right angle to the antenna and attached to the base of the antenna. Google "antenna tiger tail"). recall that a VSWR of 1.0 is perfect and larger numbers are bad.Max VSWR without tiger tail: 2.15Max VSWR with tiger tail: 1.8Power output was not stable in that it changed with frequency and whether I was touching the case or not. In general, lower frequencies and touching the case produced more power. At 88MHz and touching the case I measured just over 9 Watts. It is not clear if the heat sinks attached to the finals would like this or not. At 108MHz and not touching the case I measured 4.8 Watts. On the low power setting and 88MHz I measured 1 Watt.The biggest annoyance was the antenna connector was not as advertised. The specifications and product images indicated a BNC type connector. The radio was shipped with an N type connector. From a technical stand point the N connector is probably better and that connector would not have changed my mind on purchasing -- but it would have been nice to know in advance so I could have ordered the adapters at the same time.I purchased the adapters from Amazon:http://www.amazon.com/gp/product/B00CXN5O62?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00andhttp://www.amazon.com/gp/product/B00CXN4EX6?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00I have attached photos of the test setup, power meter readings at low and high power (readings taken at 93.7MHz) and the connector at the back of the unit.All in all I like the unit and I recommend it to a friend who also bought one. As always though -- buyer beware - as things on these inexpensive imports can change.
Perfect for doing a drive-in church parking lot service! I was going to purchase a more expensive one, but this one would arrive quicker so went with it. It was all we needed and glad we did not get one that reached further. This one reached over a hundred yards.
Get's the job done, once you figure it out.
It works. Thus far I have only used it at the low power setting. I drive the transmitter with an older laptop that I have used as a way to push my Google Play Music to a home stereo. The signal quality seems to improve with the quality of the radio used for reception. I have two home stereo systems, and a high-end portable shortwave which covers the FM band. Each radio indicates that I am receiving a strong stereo signal. However, the cheaper the radio, the worse the signal quality seems to me.I had some difficulty getting the transmitter's signal strength right so my cheap boom box would sound decent. What finally worked was putting the antenna perpendicular to the transmitter's antenna. So, maybe the transmitter unit is overloading the cheap radio's ability to handle a strong signal. So, that is likely not this unit's fault.Another key to using this device is effectively is to use your own patch cord. The noise went down when I used a higher quality cable. Also, don't overdrive the input. Set your volume level at about 60 to 70%.The other reviews are correct, the fan is way too loud and sounds like it is coming apart. It is so annoying that I may open this unit up and install a better fan. Additionally, the directions that come with the unit are the bare minimum and take a bit to decipher. They are not the worst Chinenglish I have ever read, but they could be better. The fan and the directions are where this unit lost a star.I didn't ask for, nor did I receive anything for writing this review.
