Go to the Hobby Kits section, then AM/FM broadcasters

I have the FM-10 and FM-100 kits, and a friend of mine has the FM-25. All
three kits will easily broadcast around your house. If you build a dipole
antenna, you can also get a little extra range. Note that this might put
you over the FCC limit; however, having a range of 1/2 a block isn't going
to be a big deal.

The 'C. Crane' FM transmitter (not a kit) is on sale for $69. Used to
sell for $99. It tunes the entire FM band. Comes with a whip antenna.

Anyone know the range of this device ?


PON,

C. Crane Co. claims "Approximate line-of-sight range of 70 ft."

However, if you want to increase the Range, it is simple to
construct an 'extension' Antenna for the FM Band to attach
to the built-in Whip Antenna or Wire Antenna.

Cut a piece of TV 300 Ohm Twin Lead to Five Foot Ten Inches (5' 10")
- At the Top-End 'strip' a 1/2" Insulation from the Two Wires
and Twist them together.
- At the Bottom-End 'strip' a 1/2" Insulation from One of the
Two Wires.
- Trim the Transmitter's Antenna Wire to Two Inches (2") and
'strip' a 1/2" Insulation from the wire. Take this wire and
the Bottom-End Wire and 'twist' them together. Extend the
'extension' Antenna Wire Straight UP Vertically.
- OR - Collapse the Transmitter's Whip Antenna. Take the
Bottom-End Wire and 'attach' an Alligator Clip. Attach the
Alligator Clip to the Whip Antenna. Extend the 'extension'
Antenna Wire Straight UP Vertically.

TBL: This 'extension' Antenna for the FM Band should improve
the Signal Quality of the current reception and "Extend" the
Range of Reception to 150-200 Feet.
