Looks like some good radios. A bit rough in places but should clean up nicely.

The main sets are the ART-13 which was a very advanced liaison transmitter used in WWII. The B-29 was the main Army aircraft that used it but the Navy used them a bit more is seems.

The BC-348 was the mating receiver to the ART-13 in many Army installations like the B-29 and lots of post war Air Force aircraft. These radios were normally associated with large aircraft that carried a radio operator. The ART-13 was one of the first steps to help eliminate the radio operator as it could be remotely controlled by the pilot if needed. Its 10 channel autotune system was revolutionary at the time and this WWII transmitter was popular/used into the 1970's.

Both your specific ART-13 and BC-348 appear to have Navy lineage. The ART-13 has a Navy contract on the data plate of themount as well as a NAS Alameda stamp on the front. The BC-348 has the Pensacola inspection stamp with a 1945 date. It has been my experience that not too many 'pure' Navy aircraft had the BC-348 installed so to speak. Meaning you normally see it where there were there were Army equivalent aircraft like the C-47/R4D or B-25/PBJ, B-17/PB etc.

Cool radios certainly worthy of effort to get them working again. You need a radio crew chief to take them under his or her wing. The dynamotor for the ART-13 is there and the connectors are available to wire it up. You basically need to build a straight harness (pin to pin) from the dynamotor to the transmitter, add power and it should fire right up.

Please be quite cautious with this radio because this transmitter puts out enough power to knock you across the room where you just might need someone to try and get your heart going again!

I heard a story of a guy working on a similar set who got one finger a little too close to where it shouldn't be and it knocked him across the room. When he woke up he said he was thankful that the door was open as he must have flown through it. He figured that if he hit the wall or the closed door that he would have been busted up a lot worse... :shock:

As with all aspects of these great warbirds we must be cautious and take great care.

Taigh's right about using caution around radio transmitters. The ART-13's dynamotor supplies 1,000 VDC. Transmitter RF power output is rated at 100 Watts, which is enough to give you a nasty RF burn. If you've never experienced an RF burn... trust me when I tell you that you don't want to. It's not just a surface burn like you'd get from touching a hot surface. An RF burn goes all the way through to the bone, and it's terribly painful and slow to heal.

Thanks guys for the information.

The Staff of the Dixie Wing has decided that they would like to sell or trade the equipment.

We are still working on the restoration of the P-63 and that is the priority #1.
