Hello ! I have a TDA7492 module with Bluetooth receiver. I have also spare 2.4GHz antennas. Is it possible in some way to replace the module PCB antenna with the external , for better range ? Thank you
Hello friends
I built a telemetry pair for a friend. An idea I used to have for a really long time, but I had lack of interest to do it only for myself.
All the system is based on arduino and NRF24L01 Transceiver module. (on the very begginings I had problems with the code on the atmega328...
Aha, thats not good news. I would input the audio signal through the 3.5mm fem.jack and maybe use the mic to say a hello :P
I will probably get a 15W fm transmitter assembled kit (RD15HVF1) for $45 to end with that thread
To transmit audio at 10 meters (killing a fly with bazooka)
Thank you...
I havent found unfortunatelly any attenuation network, so i believe that its just a micropower transmitter.
I am interested in buying a BH1417 kit that found on ebay, but dont know if that too can transmit more that 2-3 meters stereo.
What do you think ?
Thank you
Hello, I found out that I had a broken old car-fm-transmitter, bought around 2008 from DX
After some "retrofit" i made it work.

The stereo however dissapears at 1.5meter (s)...
