MINITRANSCEIVER NA PASMO 3,7MHZ TRX2008 - SELF-ASSEMBLY KIT
Producer: AVT
Amateur QRP mini-converters are usually simple constructions of low power transceiving devices. They enjoy unflagging interest of radio amateurs around the world and are used especially during holidays or holidays. It can even be said that work with little power on hand-made equipment is currently experiencing a real renaissance. Interestingly, many devices use 'old', underestimated TCA440 systems (UL1203, A244). This is the construction we present. It is easy to make and characterizes it (as for an amateur transceiver) very good working parameters.
The device is especially recommended to all electronics-amateurs
Selected parameters:
- operating frequency 3700 - 3750kHz
- the ability to easily change the operating frequency (depends on the LC elements used)
- SSB-LSB emission
- Receiver sensitivity 0.5uV (for 10dB S + N / N)
- output voltage of 1V transmitter (maximum value for modulation)
- suppression of unwanted sideband> 40dB
- attenuation of the tidal wave> 40dB
- power supply - 12Vdc
- dimensions of the 100x90mm board
- in the set a printed circuit board, a set of elements and documentation
