I ended up talking to Scott Nixon on this and he said he'd familiar with the SST-1 transport and that if I already HAD something like the jitterbut or simlar that it wouldn't hurt to put it in the chain, but if I didn't that adding it or going out to get it wouldn't help. Apparently the SST-1 has a pretty excellent coax out engineered into it so it doesn't need much help. This fits with what I heard from Steve McCormack, however, since he actually built the thing I took it with a grain of salt until corroborated by Scott.
Thanks for the help!
