The 311 appears to be a set of level converters to convert the "one open collector per band" output of the Orion/Orion II to the +12V select lines (160/80/40/20/17-15/12-10 M) for the the Herc 2.
The K3 does not provide decoded band data - its output is Yaesu format BCD. In order to use the K3 with TenTec 311/Herc 2, it is necessary to decode the BCD data to "open collector per band." The simple solution for that decoding is the W9XT "BCD-10" board: http://www.unifiedmicro.com/decoder.html. You will need to supply your own case, power supply (or borrow +12V from the K3) and the matching connectors for both the 311 and K3 ACC jacks. 73, ...
