I have updated my Ebay auction listing to include an MP3 sound file you can
download which is an ACTUAL recording of how the FM transmitter sounds
on-the-air.

Transmitter is an assembled and tested unit -- not a kit.

This transmitter design DOES NOT use the "BA" or "Rohm" analog chip -
ANYWHERE IN IT AT ALL. Which is a good thing.

This transmitter can equal the sound of commercial FM stations. It
outperforms ANY of the Ramsey transmitters, including the "export" version
of the FM-100B which Ramsey sells for $429.99.

You can buy this transmitter for much less than that.

Here are the specifications for this transmitter (from the manufacturer):

Transmission Frequency: Adjustable between 87-108 MHz
Tuning Steps: 10 kHz
RF Power Output: Typ 1Watt @ 13V or 2 Watts @ 24V
Spurious RF Emissions: Better than -45 dB ref. to carrier
Frequency Stability: PLL Typ +/-1KHz
SWR Ruggedness: Withstands 30:1 SWR mismatch
RF Output Connector: BNC type
Audio Input Sensitivity: 0.8V rms for +/- 75 KHz deviation
Signal To Noise Ratio: 60 dBu
Frequency Response: Flat from 20 Hz to 15 KHz
Stereo Separation: 40 dB
Pre-emphasis: 75 uS (standard FCC spec for U.S. FM radio)
Audio Distortion: Better than 0.2 % THD
Audio Input Connectors: RCA Phono Jacks
Power Jack: Coaxial type, 5.5mm O.D. 2.1mm I.D. center positive
DC Power Input: 12 to 24 Vdc Regulated 600mA

The transmitter has a built-in user options menu system with two buttons for
adjusting operating parameters such as transmitting frequency, modulation
level, MPX pilot level, etc.

This transmitter has a clean RF output. The design includes a seven-element
Low Pass RF Filter for harmonic suppression.

This transmitter has built-in audio AGC (Automatic Gain Control). The AGC
feature can be adjusted using the user options menu or you can turn it off
if you like.

Operating instructions will be included with the unit.
