The NCX -1000 is an example of top engi- neering design providing receiver performance unmatched in any previous amateur transceivers, and transmitter operation of unsurpassed excellence. Check the specifications of the NCX -1000 and see what a coordinated engineering approach means in terms of performance. Consider that each circuit has been conservatively designed, and built with carefully specified parts, and you may correctly deduce that this is the most reliable transceiver available today.
