Page 3: Product Description
Shenzhen Friendcom Technology Development Co., Ltd. 1 Product Description FC-302 is a synthesized 5-watt FM transceiver module, which is designed for data transportation and voice communication. For the voice communication, it can support selected pre-emphasis, squelch and audio amplifier. The radio is PLL(Phase Lock Loop Synthesizer) /microprocessor controlled with 4FSK modem. The application of two-point modulation with good low-frequency response in the radio also makes it a competitive choice for 9600bps rate data application. -

Shenzhen Friendcom Technology Development Co., Ltd. For data transmission test with 4FSK modem, the jumper’s position need to be changed shown as below. 4.2 Operation Instruction Detailed instruction for channel and system configuration is described. Especially, in input channel data, data input method for Rx,Tx frequency, Rx,Tx option such as CTCSS, DCS, scan and bandwidth is explained specifically. - Page 10 Shenzhen Friendcom Technology Development Co., Ltd. First of all , open the con port. The CON port is with characteristics of 9600bps, 8N1 and click “Open” as picture shows.
- Page 11 Shenzhen Friendcom Technology Development Co., Ltd. If user puts mouse cursor on the each icon in tool bar for a second, message for function indication is displayed. Power on the radio, after 5 seconds, click on the "Read", establish the communication with PC and radio. As the following picture: Warning: 1.
- Page 12 Shenzhen Friendcom Technology Development Co., Ltd. within 120 seconds after last operation, user should restart the radio for setting. 2. The BUSY signal, SWITCH and CTCSS/DCS will only be available after 2 minutes when user finish programming setting 4.2.2 Input Channel Data In this option part, user can input channel selection from 1 to 16, Rx,Tx frequency, Rx,Tx tone option such as CTCSS, DCS, power, switch and make SCAN list, and choose bandwidth, Narrow or Wide according to each channel.
- Page 13 Shenzhen Friendcom Technology Development Co., Ltd. User can decide the channel spacing in this feature with optional 6.25KHz (Narrow) or 12.5KHz (Wide) channel spacing. 4.2.2.3 SQ level Five SQ levels can be select in our radio. Level 0 is for fully open mute. The audio signal will continuously transmit.
- Page 14 Shenzhen Friendcom Technology Development Co., Ltd. CTCSS/DCS User can encode tones with CTCSS/DCS according to options shown in the picture. The feature is not available for high speed data transmission. Switch When we use radio remote: the Switch function can be use to change a logic from +5V to 0V minimum. The judging condition is long period of 260Hz, sine wave 300 Ms.
- Page 15 (set by “stop when timeout”) after the radio released PTT. 4.2.3.3.3 De-emphasis Volume FC-302 radio output voice via SPK Pin with 9 levels volume. User is able to select appropriate volume for the connected external speaker in this feature.
- Page 16 Shenzhen Friendcom Technology Development Co., Ltd. Power Save Time When Power save is enable, sleep time can be programmed from 20 to 500 ms in 20ms increment with 1~25 optional values. That means 1 equals to 20 ms, 2 equals to 40ms ..25 equal to 500ms Standby time can also be programmed from 40 to 600 ms in 40ms increment with 1~15 optional values.
