(pronounced "g-e-moto" as in GE and Motorola)
 

 

Welcome!  GEMOTO is not a club.  GEMOTO may be thought-of as a quasi-social networking group or consortium made up from members and officers from several New England radio clubs with common interests.   This is a central depository area for New England hams who share an interest in:



Mike Giovannucci, N1OMJ with his seed stock of 50 Motorola MTX9250
900MHz  portables. Mike and K1BOS purchased these to resell at a low
price to help increase 900 MHz activity in the Boston area.  It worked!


And one year later with 52 MCS2000's  (quickly sold out within days)

  • Conversions of surplus commercial GE and Motorola gear to ham operation... from P25 digital to tube type!
     
  • VHF-FM operation on less-than-mainstream bands such as 10 meters, 6 meters & 440
     
  • A pioneering effort at 900 MHz  (see left)
     
  • VHF and UHF digital (both APCO P25 and now some D-Star)
     
  • Kenwood commercial gear is also well respected and we are adding a Kenwood section.
     
  • Building and operating ham repeaters
     
  • Preservation of the great engineering heritage from two companies in their once-dominant eras.
     
  • Lately, even large group buys of 900 MHz portables, mobiles and repeaters to convert.

We're also realists so we admit to occasionally using traditional multi-band Yaesu, Icom and Kenwood ham appliances.  But again we aren't a formal club, we are just a group of hams with common interests..

Local knowledge

Members of this group tend to help each other via equipment contributions, skills, time, etc.  We are not a formal club, we are just a group of approximately 100 local, active hams with common interests.  Due to a sudden surge of low-cast surplus gear, operations on 900MHz is currently the hot growth topic.  When in the area, members can often be found on:

  • 29.60 simplex  TX PL 151.4    vertical antenna polarity 
  • 53.07 MHz  Mt. Uncanoonuc, NH  W1DC   (large system, link to details)
  • 53.77  MHz PL 71.9 now on the air central New Hampshire
  • 51.74 MHz PL 71`.9  Hopkinton, MA linked to Gunstock
  • 53.27 MHz  PL 71.9  Framingham, MA   WA1NVC
  • 53.65 MHz  PL 71.9  Windham, NH    N1WPN
  • 448.175 MHz   PL 88.5  Framingham, MA    WA1NVC  IRLP node 461
  • 900 MHz:   List is now too large.  click here

Interestingly, members of this ad-hoc group are often not local to Framingham or even Massachusetts.  Due to the wide area six-meter coverage, additional participants come from New Hampshire, Vermont, Maine and Rhode Island.  A wide-area 900 MHz repeater link-up seems to be gaining traction.  Aside from on-air sharing of knowledge, the group meets every month for lunch at restaurants in diverse  geographic locations.  We typically swap war stories on how to acquire, convert and operate GE,  Motorola and Kenwood commercial gear and build ham repeaters.  The restaurant table is usually littered with both nachos and walkies of the commercial variety.  Several of our 100+ participants have previously worked for two-way radio dealers in past lives although only three are currently employed in that field .

Others simply enjoy the less crowded bands, the occasional technical conversation and the opportunity to meet new friends with similar interests.

Typically on the third Thursday of the month, we have been meeting for 11:30AM luncheons at Rte-128 area restaurants.  An evening dinner group has also been started further south and west.  Monthly breakfasts are in Northboro, MA.  Turnouts now seem to exceed "real club" meetings even though we do not want to become a large group that requires some form of formal management.

If you get a twinkle in your eye when someone mentions a Delta, 41V,
MASTR-II, TK690, Spectra, GTX, MTX or an Astro Saber, you'll fit right in!

In the 70's,  a souped-up 2m HT220 was used by the BMOC's.  In fact, that MADE them a BMOC !
 


The Motorola GTX and Spectra series are now used on
many new 900 MHz ham repeater systems.

Just GE Delta,  really fast.  (RANGR too)

One of our newest projects is to compile links to certain rare documentation on the GE Delta and GE Rangr series of radios.  Due to the demise of the former GE Land Mobile empire, this information is becoming increasingly difficult to obtain.  This section has links guiding you to radio combination/model numbers, control head variants, cable part numbers, and more.

NEW non-mainstream repeaters worth noting.

These folks have worked long and hard to provide new services so please take the effort to reprogram your radios
and check them out!
