QST

Effective this date the former GE Mstr II repeater and its associated ACC RC-850 at the La Vigia site has been decommissioned. In its place is a GE MSTR III which will act as a surrogate system without any bells and whistles. It has the required time out timer and a CW ID. The remote TZ receiver at UCSB and voter will go away for the time being. All voice announcements has now gone away so personnel must make voice announcements as needed. The wide-band GE MSTR III will remain in place as a excellent standby system for the foreseeable future after system upgrade.

As explained by Matt Lechliter, w6kgb, at last months club meeting, the Mstr II will be converted to a uMstr with the addition of a new RLC Club Controller. Essentially the former repeater retains the same electronic design configuration. However, all the mixed cabling used for multiple variants will be discarded which will make the system easier to maintain by improving the common interconnections. A single RLC controller is now capable of handling six serial interfaced independent systems, multiple macros, and planned system interfaces tailored to the needs of emergency services and daily users. Commonality of a single controller will have the capability to interface the six-meter repeater, 440 IRLP repeater, the UCSB remote link and voter, ELT receiver, NWS warning system, etc. Command integration of the 146.79 and 145.18 repeaters will now be possible via ethernet controls over the clubs microwave system. Most importantly the controller will be ethernet capable which will ease the load on control operators through remote configuration. We shall try to maintain the basic configuration of the previous club and ARES net functions as best possible. But no two systems have the same design features and capabilities so we must adjust and learn. As we move forward the first task is to upgrade the MSTR II to a uMstr. This should take about 2 months. Meanwhile the task of interfacing the six-meter and 440 system will be on-going. In time you shall see a much more capable system.

A last word about the RC-850. The controller was way ahead of its time in the 70's. It has served the club extremely well by performing a myriad of timed macro's, voice synthesizer, paging variants, auto-patch capabilities, plus many control bells and whistles as a single system controller. The limitation of the 850 was interfacing of remotes or additional functions plus finding personnel who wanted to spend their time understanding the unique command software controls and becoming a good control operator-engineer. Hat's-off to the ACC people. They designed a controller that worked flawlessly for over 35 years. But time moves on. Hopefully the new system will attract competent technical people who love to work with systems integration.
