REMINDER: CHECK YOUR FILTERS

While it is always important to maintain a regular schedule to keep clean air filters feeding your stations, the  recent fires in Canada have put a lot of debris in the air, and the air filters will likely show it, especially if you are in the Northeast. But, do not take this reminder only for the transmitter and AC units – check you car air filters and home systems as well.

THE SECRET TO THE NEW BE 5 kW TRANSMITTER
It is almost hard to believe a 5 kW transmitter in 5 rack spaces and 65 pounds. But the new AMX series from Broadcast Electronics has done it, using some new components. Tim Hardy explains how it was done.

WHEN THE SOLID SIGNAL IS NOT SO SOLID
Every station is always looking to improve their signal as much as possible to make the listener enjoy the programming. But, AM signals can fade, due to a combination of signal scattering and diffraction loss over obstacles. Recent measurements made by John Kean show how even 50 kW powerhouses can suddenly disappear while driving through a city.
