Yaesu FT-1900R is a robust 2-meter FM mobile transceiver known for its durability and high performance. Operating within the frequency range of 136 to 174 MHz, it delivers impressive receiver capabilities, making it a reliable choice for amateur radio enthusiasts. The transceiver features illuminated front panel keys for easy operation in low-light conditions and is equipped with 200 memory channels, allowing users to store and quickly access their preferred frequencies.
In addition to its primary functions, the FT-1900R includes a 10-channel NOAA weather receiver, ensuring users stay informed about weather conditions. It incorporates CTCSS, DCS encoder, and decoder circuits, enhancing communication privacy and clarity. The device also supports keyboard frequency entry directly from the microphone, streamlining the tuning process into specific channels. Furthermore, one-touch access to Yaesu’s WiRES-II Internet Linking System facilitates seamless connectivity for users looking to expand their communication capabilities.
With a compact design measuring 5.6 x 1.6 x 5.8 inches, the FT-1900R features a rugged die-cast chassis that can withstand the rigours of mobile use. The rear panel includes an external speaker jack for enhanced audio output. Like the FT-1802M model, the FT-1900R offers a Memory Only mode and an additional 5 watts of power, making it a versatile and powerful option for novice and experienced operators.
The FT-1900E is a versatile transceiver designed for amateur radio operators, offering a frequency range of 136.000 to 174.000 MHz for reception and 144.000 to 146.000 MHz for transmission. It supports various channel steps, including 5, 10, 12.5, 15, 20, 25, 50, and 100 kHz, with a standard repeater shift of ±600 kHz. The device operates in F2D and F3E emission modes, with an antenna impedance of 50Ω, unbalanced. Its frequency stability is impressive, maintaining better than ±10ppm across a temperature range of -20ºC to +60ºC.
Regarding power consumption, the FT-1900E is efficient, drawing less than 0.7A in receive mode and varying from 4A to 11A in transmit mode depending on the output power selected (5W to 55W). The transceiver measures 140 x 40 x 146 mm without knobs and weighs approximately 1.2 kg. Its power supply operates at 13.8 VDC (±15%), with a negative ground configuration, making it suitable for various setups.
The transmitter features variable reactance modulation, offering 5, 10, 25, and 55 watts output power settings. The receiver utilizes a double-conversion superheterodyne circuit, providing excellent sensitivity of better than 0.2 µV for a 12dB SINAD. Selectivity is rated at 12 kHz / 28 kHz (wide) and 9 kHz / 22 kHz (narrow), ensuring clear communication. With a maximum audio frequency output of 3W into 4Ω at 10% total harmonic distortion, the FT-1900E is a robust choice for amateur radio enthusiasts seeking reliability and performance.
