KN-Q7A - 7 MHz 40m 10 Watt SSB Transceiver Kit
|Model:||KN-Q7A 10W 40m Transceiver Kit (incl Encl and 2nd Crystal)|
Fun to Build!
The KN-Q7A Transceiver Kit is a great project for licensed Radio Amateurs who would like to build their own SSB Transceiver. Apart from 1 medium-sized SMD transistor, the kit uses conventional leaded components on a quality PCB with moderate component density and a classic uncomplicated circuit design. Assembly should be no problem if you have with some previous Kit building experience. With guidance from an instructor, this kit also make a good first project for Novice Operators.
The kit comes complete with black enclosure and all components including a A5 printed assembly manual.
(No Internet connection required to build or operate this rig)
KN-Q7A kits from SDR-Kits are supplied with a crystal socket which allows a change of VXO Crystal
Two Crystals supplied in kit, Tuning range of 7080 kHz - 7100 kHz and 7110 - 7130 kHz
Optional matching KN-Q7A Speaker- Microphone available
Fun to Operate!
10W SSB RF Output and 0.5 uV Sensitivity assures solid On the Air performance - Simple to operate!
Ideal for Portable or Emergency use in combination with a 12V Gel battery and a 10m Fibre mast antennaas
