Introduction:
This product is handcrafted one by one by HAM. Its workmanship is crude and cannot be compared with commercial products. We will do our best to show you the most authentic photos. Please consider carefully before purchasing, and be able to accept rough workmanship before placing an order for this product.
This is a HF band QRP SSB / CW transceiver. It is very small and easy to carry outdoors. It uses a 0.96 "OLED LCD screen for easy reading.
Built in speaker, support to connect to PC, use FT8, jt65, FT4 and other digital modes, support CW mode, software control, and support CW automatic decoding。
Features:
1) 4-band coverage 10/15/20/40M 4 Band (modified based on the source program and different from the source program)
2) Excellent PCB design and excellent circuit performance.
3) Using 13.8V power supply, the power can be up to 3-5w in three bands, and the SOT-223 packaging pad required for upgrading is reserved.
4) High launch efficiency, with 40m / 20m efficiency higher than 80% and 15m efficiency higher than 60%. (Note: transmission is prohibited in non 40m / 20m / 15m / 10m band and can only be used for reception)
5) Ultra small volume and weight: 82 * 50 * 20MM (excluding protruding parts), body weight 180g, very suitable for mountaineering.
6) Multiple interface - cat, MIC / key, audio (headset supporting Android adaptation).
7) 100V or 250V cog / NPO capacitors are used for LPF.
8) Use Omron magnetic holding relay, TCXO Crystal oscillator
9) Use ne5532 operational amplifier chip.
10) Built in high-quality speakers.
11) BNC antenna interface.
