All of the knowledge and articles relevant to the voting comparator and MICOR receiver-based mostly Spectra TAC receivers and Auxiliary receivers can now be discovered on this web page. Additional conversion information for MICOR receiver boards will be discovered on the MICOR web page listed above. We'd like to have some further contributions to this web page! While this occurred to some MaraTracs, it may also happen to quite a lot of other trunk-mount or distant-mount radios which have management head cables and connectors.
