Hi,
I finally got the time to construct audioguru's FM transmitter (MOD4) after so long. It worked upon first power-on. I am using a 80cm wire as an antenna. The wire is mounted on my window on level 5. Approximately 20m opposite the window is a tall (12-level) and wide building. Within our apartment, the reception is very clear and sound quality is excellent.
The distance I got when testing the transmitter - by walking around on ground level with my pretty sensitive PLL radio - is approximate 300m, from the transmitter to the point where the transmitted sound can no longer be heard.
Also when walking around, I notice that signal strength is not consistent. Only within a few meter's radius, there are points where the audio can be heard clearly while there are also places where it is severely distorted.
Is this expected due to the obstacles between the transmitter and the radio? or is there more to be done to improve the range?
