Hi,

I don't know what the correct chain is but if you know its dimensions try matching them to the many varieties available at McMaster Carr here:

I would think a "standard" size was used even back then!

Great radio.  Basically the TS440 receiver.

Love the audio my TS440 makes.  Run into a small amp and a decent speaker they really shine.

Kenwood does have a signature sound and you can tell they are an audio company first.

Spent a lot of money at EPO when I lived down the street from them!

Still have a few dm19 caps I bought from them left over from the amp building days!

Can anybody point me to the correct chain that is used on the band change mechanism for the National Nc-300 receiver?
 I have tried a few different 'new' chains, and I believe the ones currently being made are of a slightly different pitch or size, compared to the remains of the original chains.
 So I'm probably looking for some new-old-stock type of deal, someone who has a reel of this stuff dating from 50 years ago.
 ANYONE?

I first met Dick at the CQ Magazine office back in the 60's.

The CQ Magazine Saturday night  party at the Dayton downtown Marriott during Hamvention time were legendary.

As promised, here is the data from the 1941 ARRgghhL Handbook that I think Steve, KL7OF was seeking.

I don't remember the spec, but I used IRF640 in my PWM.


Cheap cheap cheap!

I also used them at 160and 80 meters.

I think the same thing happened to 73 Magazine. I was told by a very knowledgable person at NEARFest years ago that 73 Magazine was still being published. They just weren't mailing it out. 

Thanks for the details Mike. We all have benefited from your vision and work (along with others) to bring back the "Deerfield Fest" in the form or NEARFest and make it a success all these years. You've done well to identify and train your successors. Long Live NEARFest!
