NC-98

 

I just joined the group.

I recenlty acquired a NC-98 and better than expected conditon. It does work, but poorly. I have just started replacing the caps and next plan to check the tubes to see their condition and to align it. I do have a manual.

I've always liked the looks of the NC-98.? I used one with a Heathkit QF-1 Q-multiplier added to it back
in the sixties but sold it many years ago.? Just a few years ago I bought another NC-98 on eBay in very
nice condition and have also bought another QF-1 to go with it.

Here's an article/review about it.



Do a web search and you'll find more information and even videos.

Hi Paul.? I had an NC-98 and a NC-190 years ago.? I liked the 98 better than the 190.? The 190 was very drifty and it had no RF stage for the AM broadcast band.? My sons now have them and they still work after I repaired and aligned them.? Good luck with your restoration.? Email me if you have any questions.? Maybe I can help you out.

Thanks and good to hear from you. I replaced most of the caps and aligned it. The alignment went okay but there was one cap that went to near the end of its limit. All the tubes are okay. I added a fuse and changed the power to 3-wire.?

I suspect that some resistors need to be replaced as their body color is somewhat dull. I only checked one and it was in tolerance.

It seems to be somewhat lacking in sensitivity but then I only have an IC-7300 to compare it to. That isn't really a good pair to compare.

The big problem is why did I get it and what do I do with it now that I am done? I guess I just wanted to see what I could accomplish as physically it is in nice condition. It really is too large to economically ship considering what I already have in it. I would give it to a local youngster if I knew one who would appreciate it.

You might give it to a local club to loan out to new tech licensees who are
interested in getting their "low bands ticket" (general licence or higher). They
can learn what different bands are like, how QSOs go, etc. I will be loaning out
one of my fix-it radios to a friend for that purpose.

If you wanted to make it have better ears, you could make a preamp for it. It
covers a wider swath of the radio spectrum than many general coverage receivers
do. If you have room for it, maybe make it a decoration in the house? That's
what we did with a telegraph key and "clicker" that goes with it. It was on a
nice wooden base and we put it inside a glass case.
