National nc-121 manual




















Toggle navigation. Forgot Password. Reviews Home. Time Owned: 0 to 3 months. The National NC is a general coverage radio that was intended for the beginning ham and shortwave listener. Its features are four band general coverage tuner, product detector, pitch control, S meter, peaking Q multiplier, two IF stages but no RF stage, power transformer, built in speaker and six tube design.

This radios is about the size of a shoe box. It is a very attractive radio with grouped controls. This radio competed in a very dense field of beginner equipment such as Hallicrafters S , and S The Gonset G33 and the G 43 also come to mind.

At the beginners level most of these radios were more like shortwave radios that covered the ham bands than true communication receivers. The NC is fairly well calibrated but has a band spread dial with a scale. This would necessitate a logging scale to have any hope of finding where you are in the ham bands. This was very common and could seen with the Hallicrafters S and S also. The sensitivity of the NC is generally very good up to at least 16 MHZs where it would have benefited from a RF stage which it didn't have.

The sensitivity on the AM broadcast band is excellent. The selectivity is fair to good. The Q multiplier doesn't work very well on the AM mode. SSB and CW effect is a little better with the control having the value perhaps of a tone control. Stability is fair in the ham bands, not as good as Hallicrafters S or the S SSB sound is pretty good but the RF gain control must be backed down on strong stations.

These beginner radios are fun to collect and usually don't sell for very much money. Much of the time they mostly meet their advertising claims and could of been used in the ham bands to make long distance contacts. More than 12 Months.
