[MRCA] [ARC5] ABA-1 IFF ( USAAF SRC-515-A )

[Bart Lee]

Hi Mark,


At the California Historical Radio Society (CHRS)  Museum in Alameda, we
have  cold-war radiation simulator (3 MHz) that uses a code disk:  about 4
‘ diameter, with red plastic teeth (see attached).  I’m wondering what the
IFF code disks looked like, as I have never seen one. Can you supply or
direct me to a photo?


Thanks
