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
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
Indication of low voltage
A little later will be available schema files and documentation.
