Model 1254 combines the satisfaction of the kit building experience
with the performance features expected in a modern HF receiver. Building
one’s own receiver from a kit has launched countless thousands of
people into communications careers or the hobbies of amateur radio and
shortwave listening ("SWLing”). You will build a true dual-conversion
superhet with a microprocessor-controlled frequency synthesizer. Digital
LED readout. Alignment is easy and does not require complicated
equipment. You only need a volt-ohm meter and your ear; the kit provides
its own 45 MHz test signal. Project skill level: Intermediate. Not
recommended as a first-time kit building project. Estimated build time:
15-20 hours.
