8 Band Short Wave Wireless Transceiver Aluminum Alloy Multifunctional Portable SSB CW QRP Transceiver Kit 100‑240V EU Plug Item Type: Short Wave Wireless Transceiver Material: Aluminum Alloy Battery: Polymer battery x 1 Battery Capacity: 5000mAh (shipped with built in battery) Function List: 1. Eer e level driven SSB transmission stage 2. 13.8V power supply approximately 10W SSB PEP output 3. Supports full mode: USB, LSB, CW, AM, and FM DSP 4. Filter: 400025001700500200100100, 50Hz passband 5. DSP functions: Automatic Gain Control (AGC), Noise Reduction (nr), Voice triggering, Voice triggering xmit, Attenuator rx (att), tx Noise Gate, tx Drive Control, Volume Control, and DBM/s Meter 6. Ssb reverse sideband, carrier suppression transmission: better than -45dBc, IMD3 (dual tone) -33dBc; Reception: better than -50dbc 7. Supports multi frequency bands. Continuously adjustable in the frequency range of 160m-10m (20khz performance loss). 99 MHz 8. Open source firmware with built in IDE; Allow experimentation, add new features, share contributions through for GitHub, software complexity: 2000 lines of code 9. V based software can be used for fast and complete malicious operations (qsk and semi qsk), or to assist execution in digital mode (without CAT or PTT interface), for RX TX switches, with TX PA delay control external PTT output, simple installation and modification, 8 component changes, and 8 lines 10. Lightweight, low cost transceiver: Thanks to the for EER electronic liquid level transmitter, it has high power efficiency (without the need for a huge heat sink) and a simple design (without the need for complex balanced linear power amplifiers) 13. Three switchable analog controllers, independent of the front receivers 0db, -13db, -20db, -33db, -53db, -60db, and -73db 14. MDS receiver noise level: -135dbm (200Hz bandwidth) at 28MHz 15. Pre receiver selectivity: steep frequency adjustment -45dB/ten fold roll down+/-2kHz x blocking dynamic range: 20kHz offset 123db, 2kHz offset 78db 16. CW decoder, directly, iambic a, b keying Vfo a b and rit and frequency division, and switching corresponding relays with filters through for i2c Cat support (for TS480 subset), can transmit sound, keystrokes, and display text through for CAT
