Order Handling Time within 3 Working days(Pre-sale products excluded).
Retevis HS3 is an ultra-portable and all-band (100kHz to 2GHz) / all-mode (FT8, USB, LSB, CW, AM, FM, RTTY, DMR (optional) and WFM (receive only), etc.) SDR radio. It is designed, manufactured, and sold by Hamgeek. With its dual VFO modes, it supports split-frequency operation, intermediate frequency offset adjustment, fine tuning, noise suppression, AGC speed selections, RF gain and squelch controls, integral pre-attenuator processing, integrated AM/FM broadcast receivers, automatic sleep and transmit-time-out timers, CAT and configuration cloning capabilities; the HS3 is truly a next generation field and QRP solution.
This is the best 150W HF linear power amplifier! It supports automatic detection of band synchronization! All you need is a PTT sync cable! 6-band output low-pass filter has been optimized. 1.8-30MHz, 150W maximum output, 15W maximum input and 4 adjustable amplification gains. With high temperature protection and high SWR protection. High-performance NPO capacitors are high voltage resistant, with low pass! The product is neat and beautiful!
HF Antennas portable short wave antenna can work in the frequency range of 7MHz-54MHz. It is a telescopic antenna and you can adjust its length. It weighs only 1.8kg/4lb and its folded length is only 52cm/20.5", enabling easy carrying. The unique matching design of sampling ensures that the standing wave is less than 1.5 and the radiation efficiency and reception gain are higher in the use frequency range. It is a better choice among broadband portable antennas.
