Help with 433 RF project & Code check

hello all,

i working on project control multiple 32 channel receivers using manual remotes. project using rcswitch, vituralwire, existing software & 433.92 transmitter. believe on 24 bit should able run 32 devices 32 channels (1024 total). software seems set , has option different receivers on different channels, when sync receivers transmitter on different addresses , run program, on same one, giving me 32 out of possible 1024 channels. i'm new i'm hoping can check code see if might problem or if has other suggestions. - z.

after research, possible encoding chip needed on transmitter? new auduino , thinking controller encode each signal software. software sound others have used success other sketches. i'm thinking must code. didn't write code i'm hoping here can verify it. appreciated. if more info needed please ask. need have project working in 2 weeks. in advance - steve.
