Digital FM Receiver Module, Icstation Radio Receiver Module Digital Stereo Board LCD Display DSP PLL 76.0MHz-108.0MHz Green

Extraordinary performance and sensitivity with a vertical 3-foot (1meter) pole or wire as an antenna. One key advantage of this DSP based design is that the mute and stereo functions are manually set. The mute arrived disabled by default and the stereo arrived always on by default. This feature is important if you desire to listen to a noisy station that would otherwise be muted out in other DSP designs. In this respect this module functions like an analog tuning, except that the tuning is exactly selected digitally.I have not explored any programmable features. Used a pair of AA batteries. The current draw was 19mA after the display light automatically goes off. This light adds about 3mA to the power draw.

My receiver receives the transmission from Icstation Digital Audio Transmitter Stereo DSP PLL Module 88-108MHz with LCD Display MIC USB Input that sits outside near my birdfeeder. The only enhancement is a piece of wire connect to the antenna hole on the circuit board. I made a front for it using my laser engraver/cutter. Not sure why, but sometimes the unit starts to get static in the output when another radio nearby has no static receiving the same transmission. Refitting the cable or headphones plugged into the TRS output seems to clear it up. So, I suspect the static is on my output side not the receiver. The photos show a couple of options I took on making a faceplate and adding a battery pack on one. The LCD display has a limited viewing angle and I initially just mounted the lower faceplate to the side of the battery pack, but the frequency reading wasn't visible while it sat on my desk. So the angled brackets were made to try and adjust the view to make it clear. I just used 3M car body double sided foam adhesive tape to mount it and some carpet tape with tool box liner under the battery compartment to stop it from sliding around. I will be giving the one with the battery pack on it to my father-in-law who is a regular caller into a Friday night AM radio talk show that just added a FM frequency in the last few months. It's too bad the unit can't be powered by switching type power supply, like a USB power bank, but I tried that before seeing the Icstation note on their web site that the unit will not work with power banks. My test with the power bank would power up the radio, but shut down within a few seconds. If I add a battery pack to my other receiver, I may look at using some type lithium ion 18650 battery holder. I admit, I did not scan the 2D bar code to view the instruction manual, but the knobs can be depressed to do different things. On the left volume knob, pressing it in will mute and unmute the audio output. The right tuning knob has two functions based on short or long press. One turns squelch on or off. The other duration allows setting of the squelch level. Basically this can limit static and ensure stations received meet specific signal level before any audio is output. Set the squelch too high, and you may think you have a defective receiver, so be careful if you adjust the squelch after turning it on.

The first unit I received had a problem with the left channel cutting out. After contacting Amazon they quickly replaced it. The second unit works fine. Despite the inexpensive price (pre-tariff) the radio has good sensitivity. With a telescoping antenna I also purchased here at Amazon it gets good reception. I hooked up two very inexpensive 70mm speakers (8ohm). I won't comment on the sound quality as the speakers are junk. I am running it off of a single 18650 battery (3.7v). It's amazing that they even include a built-in 2 channel, 3 watt amp at this price. It drives my speakers very easily. I typically keep the volume at about 1/3rd level. I 3D printed a simple case and I now have a nice FM radio to use in my garage.

The media could not be loaded. Great little FM radio module. All you really need is DC battery power and a speaker or two. It has a built-in amplifier already on board, so no need for an external Amp. There is a solder pad on the board for you to select if you want stereo or mono. It came with absolutely no instructions, so I'd assume it's stereo by default, and if you want mono you just bridge that solder pad. That's what I did and it worked..You do need to solder a length of wire to the antenna pad on the board in order to get multiple stations. Also has a 3.5mm headphone jack.No, it's not a Bose acoustic wave machine, but it is perfect for building your own FM radio in a box or chasis of your own design.
