12 New Portal Members Registered in the Month of July! 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. What type of information can i find in the Members Portal? Coming Soon: The 813 Beam Power Tube & Data Spec.
