I never kept them written down, sorry. I know it's red white blue, but I forget which is which for the Astatic, I think red was PTT, white may be audio and blue audio ground with black the general ground...but it's been a while now. I just matched them up to the modular connectors' specs which are in the user manual for the 857.
I can tell you this, that I run a 636L now as the other two simply had too much gain for the 857...that already has a super hot mic input. Even with the passive 636L, I run mic gain at 4 out of 100 for FM and for SSB maybe 18 out of 100 at most with no proc at all.
