SO, WHAT'S NEW? - By Michael K2SHF

First off, I hope all the mothers out there had a lovely Mother's Day.  The weather here on Long Island was far from pleasant, but doing something fun with my mom surely made up for Mother Nature.

Let me be the first to congratulate Caleb, KO4UYJ, on being voted in as our newest facilitator for the East Coast Reflector.  Caleb has been hard at work for the past several months on project after project, including the all new ECR App and the P25 and M17 bridges to the system.  Caleb already has other projects underway.  He is also busy as a Control Station on the system, and helps users who need it as well.  We look forward to seeing what else Caleb will be coming up with in the future.

The ECR name badges are a hit.  Many of our ECR family have already gotten their badges, and I've heard nothing but positive reviews.   You can order yours at https://thesignman.com/clubs/eastcoastreflector.html.  The ECR makes no money on these.  Check it out and see if this is something you'd like to add to your ECR swag. 


Thank you to all who checked in to the Morning Brew.  The following are answers to some of our recent daily questions.

We asked the following questions.   As always, only answers with a tally of 2 or more were included below.  Thanks to Derby Dan (KD2VNU) for his hard work in logging the answers and tallying the results after each net.


The following hams are celebrating a birthday over the next week.  Happy Birthday to you all!

KJ4TPE, Rick of Orange City FL, has a birthday on Monday, May 9th
W2AJR, Andy of Cheektowaga NY, has a birthday on Saturday, May 14th

Would you like your birthday recognized in the Newsletter and on the air during the Tech Net?  Just send an email to K2SHF(at)ARRL(dot)NET with your callsign and birthdate.  Your birthday will then be added to our spreadsheet.

Yes, the spelling is correct, GE Mastr II, not Master II. I saw my first Mastr II mobile in the early 1970’s. It was installed in a Kentucky State Police cruiser. KSP began an upgrade from Low Band to UHF 453/458 MHz during this time period and operated both systems until each Post had completed the upgrade.

It is a well-known fact that manufacturers in that time era purchased their respective competitor's equipment and then dissected it in their engineering labs. A hands-on approach one might say.

Reliability plus serviceability was a much strived after feature that both GE and Motorola were developing. The concept was simple, design a solid-state two-way transceiver that could easily be serviced in the “field”, and get the customer back on the air asap. However, this took many hours of research and development. Both Motorola and GE were highly successful. Both produced Mobiles and Stations/Repeaters with interchangeable circuit boards that could be removed and installed without soldering.

The result was two highly reliable/quick serviceability radio lines, the GE Mastr II and the Motorola Micor series. MICOR was named for “More Integrated Circuits for Optimum Reliability”. The Micor mobile radios brought the development of the infamous “Micor Squelch”. This concept incorporates a two-level hysteresis type squelch control circuit, allowing a weak signal to present a slow squelch closure, and a full quieting signal a fast squelch closure.

Many agencies purchased spare boards for the most common failures. A portable test set could also be used to assist in locating a fault, and/or adjusting. The defective board could then be taken back to the shop, repaired, and become a ready spare. The station/repeater power supplies were of fairly simple design, and being solid-state, no high voltage was necessary unless rf power was above 110 Watts, which required a high voltage power supply. Both Mastr II and Micor mobiles and stations require a key to open.

GE manufactured many radios after the Mastr II, including Mastr Executive II, Custom MVP, Mastr III, Rangr, Delta, Phoenix, Orion, but Mastr II was by far their most popular unit. Ericsson joined with GE around 1989, and continued the GE two-way manufacturing. Eventually GE sold their interest in the two-way market.

Motorola of course remains a premier manufacturer and leader in the two-way communications industry today.

The Narrow Banding mandate by the FCC made both the Mastr II and the Micor obsolete for commercial radio service even though the units were or for the most part still fully functional. when removed from service. Today many are still in use by amateurs as repeaters throughout the world, and in use on the East Coast Reflector system. I have included some recent pictures of “new old stock” Mastr II’s as they are being unboxed to sell at auction. GE changed the Mastr II cabinet color in later years to gray and black, which carried on with the Mastr III series. I think this speaks well of the reliability, brand-new spare units, now retiring, never “called to service”.
