TX-FM1/W VHF FM Broadcast Exciter Transmitter

This 30W FM exciter, is intended for radio stations who want the convenience and cost
saving of an integrated RDS encoder but who would prefer to specify their own stereo
generator/audio processor.

EMC compliance and professional performance are assured, thanks to independent testing
and approval to ETS 300 384 and ETS 300 447 (under the R&TTE Directive 1999/5/EC).

Aimed at a new generation of radio stations and engineers, antiquated and slow acting
needle meters have been replaced by analogue to digital measurement technology. The
backlit LCD, together with ergonomic front panel controls, allows simple menu navigation
for easy option selection and setting.

At the heart of the TXFM1 /W is a high quality modulator employing proprietary
‘complementary varicap compensation’ resulting in constant modulation across the entire
band for true broadband performance. The carrier frequency is user-selectable via
internal ’dial-up’ numbered BCD switches.

ALC (Automatic Level Control) of the broadband RF power amplifier ensures that ERP not
only remains within the permitted limit, but is also continually optimised for maximum
reach. SWR cut back, and both audible and visual alarms activate in the event of
mismatches in the antenna system.

The rugged TX FM1 /W incorporates a Switch Mode Power Supply and local switching
regulators for efficiency. Convection cooling, plus carefully specified, quality components
ensure continual service for many years without maintenance, making the TX-FM1 /W
the obvious choice for today’s quality driven, yet cost conscious, radio stations.
