Great article on restoring vintage radio's

Shameless link from Warbird News site.

Really interesting what is needed and done to get vintage stuff going on the Dakota Territory Air Museum’s P-47.

Scroll down to the radio section of the article.

May I point out.....not cheap to do vs only sticking in modern stuff.....Just look on how they are stuffing modern capacitors inside old capacitor casings!!!! Pretty cool.

Are vintage radios still in service in the U.S? In Europe, the 8.33 kHz channel spacing has killed off all old equipment and "old" includes radios as "young" as a few (5-10) years.

I've done a bit of restoration of WW2 radio gear. It's a labor of love, and not something that can be rushed.

Re-stuffing capacitors is fairly common when restoring old radio, audio, and musical equipment where it's desirable to maintain the original look. It's not terribly difficult, but it is a bit time-consuming.

In the US military those old bands are long obsolete I think. I know for civilian equipment the bandwidths have been tightened up and bands added between the old ones.

The research takes a long time.Manuals are one thing but seeing all the details on how its all put together as a complete system is another.I,m trying to get my head around how the Spitfire radio and IFF is all connected.

How does one get the electric / electronic schematics!!!???

Which is the basics to get it done!

I have no idea about Swedish military but I assume that they have moved on as well. For civilian use there are a few 25 kHz spacing frequencies set aside for aircraft and gliders where investment in new equipment is too expensive. Those frequencies and the two 8.33 kHz spacing channels on either side are not alotted for use on new equipment. However, that would prevent you from going to an airport or through controlled airscpace with 8.33 kHz spacing channels.
