SCR-197

The SCR-197 was a ground mobile high frequency radio station used by the United States military prior to and during World War II, notably during the Battle of Wake Island in 1941.[1]

Specifications

The SCR-197 mobile station consisted of the BC-325 radio transmitter with a frequency coverage of 1.5 to 18 Mhz and an RF power output of 400 watts. Radio receivers consisted of three BC-342 and one Hallicrafters S-20R "Sky Champion". Also provisioned was a BC-119 control box. The complete set was housed in a K-18 truck and K-19 trailer combination. A 45 foot vertical antenna was used for sending and a 15 foot whip used for receiving. Power could be optionally supplied by power mains or portable generator units: one PTO driven GN-42-A generator for the transmitter and two small PE-75 skid mounted units for the receivers. The SCR-197 set was later replaced by the SCR-299.[2]

gollark: The correct way would be to use IPFS or something, but this is not widely done.
gollark: Or it could just randomly break at some point.
gollark: But that's not remotely decentralized, and the NFTs don't even bother to contain hashes of the image or anything, so it's entirely possible to make your server show different people different things.
gollark: See, storage on-chain is really expensive, so most NFTs just contain URLs for the actual image.
gollark: Oh, that reminds me, NFTs are really stupidly implemented most of the time too.
