What is The Members Portal?

it's a no-nonsense collection of some of the most useful and
invaluable technical files available today for the hobbyist and
the full-time radio shop technician in assisting in the service
and repair of a wide range of 2 way radio equipment, including
citizens band, 10 meter export and amateur equipment.

Who Subscribes to The Members Portal?

a large majority of our membership subscribes to the
Members Portal in an effort to confine their search for critical
technical information and relieve them of the necessity of
having to constantly search the world wide web everytime they
require the necessary support documentation needed to service
and troubleshoot a wide variety of problems related to their
everyday bench work. people directly involved with the industry
can begin their search here and forego the aggravating and
time-consuming procedure of asking questions in forums on the
internet and in the case where the information they seek is not
readily available our staff can perform the legwork for our
members and see to it that the information is added to the
portal for the benefit and use of all.
