The transceiver is built on the scheme with a single superheterodyne frequency conversion and four Crystal quartz filter. The device is controlled by a microcontroller. The frequency synthesizer used as a local oscillator on-chip SI5351 The transceiver is designed to operate in the lower (LSB) / upper (USB) sideband as a phone (ssb) and CW (CW). It is possible to work in digital modes.
Power supply in the 10-14 (13.8 Nominal) Current consumption in receive mode with an average volume of 100 mA 600-800 mA in transmission mode (mean 700) Receiver sensitivity better than 0.4 Microvolts Transmitter Output Power 3 W nominal. (Max 4 W) Low-pass amplifier Output Power 0.7 W
Intermediate Frequency 9 MHz Band crystal filter bandwidth 2.9 kHz at -6dB
Switchable LP filter (200,300,600,900,1200,1500,1700,2000,2200,2400,2700,2900 Hz) with a fairly steep slope. Carrier suppression more than 70dB Suppression of non-operating side, more than 70 dB
Functional: LSB / USB CW / SSB / DIGI Two AGC mode (Fast / Low) Signal strength indicator (S-Meter) Vertical / semi-automatic keyer Turn on / off key for CW transmission Enable / disable the transmission of AF signal at the input. For digital modes (DIGI-VOX) The offset frequency for CW Self-control for CW Lock encoder Indication of low voltage A little later will be available schema files and documentation.
