Only power on after confirming that everything is working properly. 2. If the remote control battery voltage is low, please replace the batteries immediately. (A low battery voltage in the remote control generally reduces the control range.) 3. When using wireless electronic products, avoid strong interference sources such as metal covers, large electronic devices, and electromagnetic fields to prevent the remote control from being too close to the receiver or causing it to malfunction. 4. Do not use this electronic product improperly. Improper use can reduce product performance and lifespan, and in severe cases, damage the product and pose a safety hazard. 5. The delay time setting is automatically set when entering learning mode. The delay time setting is linked to the number of times the learning button is pressed. Please pay special attention to this.

Support for multi-band support, in the 80m frequency range of continuous adjustable 10m (from 20khz. 99mhz, loss performance)6. Open source firmware, built using Arduino IDE; allows experimentation, new features can be added, contributions can be shared via github, software complexity: 2000 lines based on7. The software vovovox code can be used for fast complete control (qsk and semi-qsk operations) or RX/auxiliary switch TX to be used in digital mode (no cat or PTT interface is required)8. The PTT/PA output is externally controlled by the all-digital tx-delay stage and the software-based SSB stage transmitter: the phase of sill SI5351 is controlled (by a small frequency change i2c at 800 kbits/s) and the PA amplitude is controlled (by a pwm pa key shaping circuit)9. Software-based all-digital SDR receiver level (optional) : sampling of I/Q (complex) signals from a digital mixer with an orthogonal sampling detector, and mathematically perform a 90-degree phase shift (David Hilbert transform) in the software by adding an Atten sideband10. Three independent switchable analog pushers (0db, -13 db, -20 db, -33 db, -53 db, -60 db, -73 db) from the front receiver11. Receiver background noise mds: -135 DBM at 28 mhz (200 hz bw)12. Receiver receiver front-end selectivity: +/-2 khz scrolling at steep 45 db/decade tuning frequency13. Blocking dynamic range: 20khz offset 123db, 2khz offset 78db14. CW decoder, direct/iambic-a/B keying15. VVFO A/B + RIT and split, and the corresponding relays pass through i2c16. The CAT supports cat with a filter switch (using the kenwood TS-480 protocol)Package includes:- 1 x transceiver- 1 x the microphone- 1 x charger- 4 x machine floor Mats
