This is a shortwave QRP SSB/CW transceivers. It has powerful functions such as using IRF series launches tube, can be used by connecting the M seats antenna, it is an indispensable tool for amateur radios enthusiasts, come and have a try, it will not let you down.
Features:
This receiver as using IRF series launches tube, can be used by connecting the M seats antenna.
13.8V power supply about 10w ssb pep output and eer e-level drives the ssb transmitting stage.
Support multi-band and can continuously adjustable in the 160m-10m frequency ranges (loss of 20khz performance)..99mhz.
Embedded DSP and SDR functions: DSP filter: 4000, 2500, 1700, 500, 200, 100, 50Hz passband, and with powerful DSP functions such as AGC, NR, VOX, ATT, TX noise gate, TX driver control, volumes control, dBm/S-meter.
Software-based vox can be used as a quick and complete invasive (QSK and semi-QSK operations), or to assist in running in digital mode (no C-AT or PTT interface) for RX/TX switching, external PTT output with delay TX/ PA control.
Thanks to the ERR level and transmitters, it has high power efficiency and simplicity design, no need for bulky radiator and complicated balanced linear power amplifier).
Fully digital and software-based SSB transmitters stage: By controlling the phase of the pll si5351 (through small i2c frequency changes over 800kbit/s) and the amplitude of pa (through PWM of PWM), the microphone is sampled and input and the SSB signal is reconstructed. PA Keys shaping circuit )
All-digital and software-based SDR receiver stage (optional): sample the i/q (complex) signal from the digital mixer of the square sampling detector, and perform a 90-degree phase shift (Hilber transform) in the software ) and remove a sideband by adding.
C-AT support (TS480 subset), you can stream audio, press keys, and display text through C-AT.
With three independent switchable analogs front-end receiver attenuators (0dB, -13dB, -20dB, -33dB, -53dB, -60dB, -73dB).
Specifications:
Material: aluminum
Plug: EUPlug, USA plug (optional)
