Specifications: Days when exposed to tune straight power: <20W Days when adjusting the input power tuning: <3W Tuning indication: LED display Interface: Q9 type Operating frequency: 1-30MHz Antenna Interface: Q9 type The antenna impedance matching range: about: 30 - 300 ohms Carrying RF power: less than 15W Tuning required RF power: less than 3W Box size: Approx. 10cm x 6.8 x 5.0cm Package weight: 210g Descriptions : 1. This is a set of DIY parts for QRP manual tuning. You need to have a certain foundation of electronic technology, understand related components, and be familiar with welding, assembly and debugging. Please read the kit instructions carefully before assembling. 2. The built-in circuit board is a standing wave indicator circuit, which is convenient for welding, simple process and not easy to make mistakes. It is the standard configuration of each version. 3. This tuning can add proper inductance or capacitance to the original non-resonant antenna to make the radio work normally. 4. It can modify the original resonant antenna, but due to external influences, the SWR of the antenna that has changed. 5. It can be used as a band-pass filter to reduce unnecessary out-of-band radiation when transmitting, and to reduce out-of-band cross-modulation and interference when receiving. Package : 1-30 Mhz Manual Antenna Tuner kitsThis kit is not a ready product but need welding and install by yourself. August Update - Products come with instructions. |
