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

stakeholders meeting at NearFest May 3, 2008.
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..

using commercial gear and building ham repeaters, be sure not to miss this great site by Kevin Custer:

Members of this group tend
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

List is now too large.
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
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
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

Real radios hurt
when you drop them on your foot.
Just GE Delta, really fast.
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.
