   We maintain a data base of station configurations to enable us to analyze your difficulties over the phone. There is NO CHARGE for telephone consultation.

   Whether your transmitters are tube-type or solid-state, we've been there and done that... Harris, Collins, Larcan, Broadcast Electronics (BE), Vislink (Microwave Radio Corporation)... we've worked with them all. *
