Terry is spot on. The original HaiCom 204III did require turning off everything but the $GPRMC string which could be done via the SiRF chipset shareware
I have several sets of Jeff's NixiChron electronics driving various clocks that I purchased from Jeff after the DST fix was incorporated. This Rev. also incorporated the change to accommodate 'todays' GPS pucks that do not have the 1PPS out. Last Rev. was "11-02-10" (Rev. is written in pencil on the top of the MCU) I use the GlobalSat BR355 exclusively now on these electroincs. Much better at locking-on too compared to the Haicom.
