For college students studying electronic technology, it can be used to test their own learning level. And QRP communication enthusiasts can use the assembled kit for various outdoor QRP communication, especially digital communication using PSK31, RTTY and JT65.
For emergency communication, it is a small and portable emergency communication equipment. To +60°C - Frequency Stability: ±1.5ppm (5 minutes on), -10°C to +60°C (standard); ±0.5ppm (5 minutes on), -10°C to +60°C (TCXO-M) - Working voltage: 915V DC - Working current: Receiving: 410MA-440MA (maximum display brightness).
Minimum LCD brightness can be reduced by 40-60MA. After hardware improvement, it will drop by 50%-80%; about 60MA after shutdown, and 3-5MA after power amplifier driver level improvement. Transmit: 3A (FULL); 1.5A (5W) - Transmitting frequency band: 3.5Mhz-? 3.9MHz, 5351.5-5366.5 kHz, 7MHzï½? 7.3MHz, 10.1 MHz-?14.350MHz, 18.068 MHz-? 24.990 MHz, and 28MHz-? Usually it costs about 30USD-50USD. If you receive the item that not satisfied or defective, please do not open case and kindly notify us within 30 days.
