new DRM transmitter, an ASI CE-50000WS, was installed in April 2018 and
is in program test at random times. The transmitter is rated at 15 kW
and is using the Rhombic antenna at 062 degrees. The authorized schedule
for this transmitter is: Monday-Friday 0700-0900 on 7325 kHz, 0900-1100

terrain. The principal radiation direction is 242 degrees true, or
almost due southwest. Minor lobes exist to each side of the main
lobe and to the rear on a bearing of 062 degrees true. The pattern
when the antenna is fed in the 062 direction is the same as 242 rotated
