It has a pocket-style design, is lightweight and portable at 0.17 lbs., and has a maximum transmission range of 200 meters. Long operating time, excellent performance offered by a 2000mAh polymer lithium battery incorporated into the radio transmitter, and faster charging speeds supported by a USB cable with a strong copper core. Because of its built-in condenser microphone, digital audio processing, and support for external condenser microphones, this radio transmitter provides a clear sound quality and excellent sensitivity. The radio transmitter may play music from your phone to the FM receiver by supporting TF card and AUX line-in with a 3.5mm male to male Aux cable. The entire public FM spectrum is available for transmission; a single transmitter can connect to a large number of FM receivers; if you wish to add more tour guides or simultaneous interpreting spaces; just carry out your needs yourself.
HOW TO INCREASE FM TRANSMITTER RANGE
The RF signal from the transmitter is often amplified using transistors (and/or tubes). Using a larger, taller, more effective, or directional antenna can occasionally be the least expensive solution to extend range.
HOW TO CALCULATE THE RANGE OF FM TRANSMITTER
The only method that is direct is to measure the voltage at the antenna. The output power will be 4/37 = 108 mW if your antenna is a quarter-wave monopole, which has a radiation resistance of around 37 ohms and 2 V RMS (VHF/FM).
HOW TO MAKE FM TRANSMITTER NOT STATIC
By adjusting the radio in your car to the FM transmitter, you may get rid of the static. Select a non-channel frequency on your FM transmitter and get it ready. Turn on the radio in your car and enter the same non-channel frequency. Turn on your FM transmitter once they are both tuned to the desired number to eliminate static.
HOW TO STOP FM TRANSMITTER FROM BUZZING
With a radio receiver, look for a blank frequency. Then, to use, switch the broadcast transmitter to the blank frequency. F, In order to lessen the humming noise, you could also try reducing the power and connecting a Ground wire from the antnna connector to the PA mixer board.
FAQs
Yes. When you turn it off and back on, the last setting is still there, you don’t need to reset it.
Yes.
For this Retekess FT11 transmitter, it works while it’s plugged into power, but it may affects the battery life.
1 mW to 300 mW. The Max power seems to depend on the FM frequency. We find at about 100 MHz the little transmitter has a range of about 600 feet or a city block.
I am sorry to tell you that this is an FM transmitter, it has no translation function. But our tour guide system can meet your needs,ASIN:B071HXVB7M,B071VW1V3B,B072FKPHHV.
This Retekess FT11 portable FM transmitter can only be used as a transmitter, you can use any FM radio as a receiver, such as Retekess TR101, V112, TR612, PR13 FM radios, ASIN:B07FD8PMHC, B019BYBR48, B088T6SV61, B01M9B10V5.
Yes, you can download music to SD card.
Yes, you can. You just need to set the frequency of the two FT11 transmitters to different frequencies, then your clients can tune the PR13 FM radio to the corresponding frequency to switch between both audio signals.
For this Retekess FT11 transmitter, It can be connected to 2.4GHZ RT receiver with 3.5mm male to male Aux cable.
Please kindly note that one transmitter can only transmit one audio signal, if you want to transmit two different audio signals, you can use two FT11 transmitters and set their frequencies to two different frequencies, then your clients can tune the PR13 FM radio to the corresponding frequency to listen to the signal they want to hear.
Yes, you can. You just need to set the frequency of the two FT11 transmitters to different frequencies, then your clients can tune the PR13 FM radio to the corresponding frequency to switch between both audio signals.
Yes, you just need to tune the PR13 FM radio to the corresponding frequency to switch between both audio signals.
Yes, this FT11 portable FM transmitter can meet your needs.
This products with Lithium battery, if you ran from the charger full time, which will reduce battery life
Yes, you can use it. And it’s maximum transmission distance is 200 meters.
