HUSD usdr-usdx Transceivers 10m 15m 17m 20m 30m 40m 60m 80m 8 Band HF SDR Transceivers Shortwave SSB/CW Transceivers Built-in Microphone Speaker with Aluminium Alloy Cover

Features:
8 band support: 80m/60m/40m/30m/20m/17m/15m/10m.
Three a-92 bs170 packing tubes are used, with a transmission power of 3-5w.
The pll uses 0.5ppm tcxo temperature compensated crystal oscillator, and the lpf part uses 100v np0/c0g capacitors to give you a better experience.
Lightweight and low-cost transceivers design with high energy efficiency.
For some weak signals, you can try to close agc or set agc to fast, att2 is 0, so the reception effect will be better.
Because the hardware structure is extremely simple, the sensitivity will decrease with the increase of frequency, so it is recommended to turn off agc at high frequency and set att2 to 0. Sensitivity will also decrease at frequencies supported by non-amateur bands.
