FM RADIO STATION TINY HOUSING PART 20
Perhaps the smallest radio station on the air today, tiny "Whisper Radio FM 102" is housed in a miniature cabinet with space for expansion.
Whisper Radio -
"To hear a whisper you need to shut out the noise of the world…"
The radio station housing is an insulated rectangular yellow polymer cabinet. Components on the inside include the main board on the left with protruding microphone at top and antenna on the left, plus a 9VDC battery over on the right side.
At the top left is the mic, and at the top right is the on/off toggle switch and a red LED power-on monitor light. The best feature of mounting the microphone this way is the shortness of the leads which are kept at only one fourth inch long, thus minimizing interference. The push through microphone, without extending the leads, creates the highest quality, best signal, and minimizes distortion.
The cabinet is "drilled" with a soldering iron that easily melts holes into the plastic. Keep the internal board to the left, close enough to the side wall but keeping clearance mounting space to include the antenna jack.
The cabinet is large enough for installing many added features described in previous posts, like the mute switch, on-the-air monitor, tone control, etc. Refer to the controls post and the index link for more details.
