Yes, you may be able to look at the manuals and drawings and engineer the connection. I think it would be much better to interface both machines to an inexpensive controller. I have a UHF and VHF Micor Station lashed up with a NHRC-4 that work FLAWLESSLY. (Thanks mostly to N3XCC)
There is also a VHF Micor, UHF MSR2000, and 220 machine all interfaced with an Arcom RC-210, that Scott built.
