Ten-Tec 715 RF - User Manual

Model 715 RF Speech Processor
Model 715 RF Speech Processor is a high performance true RF-type speech processor
designed to operate with most modern HF Amateur Radio transceivers. RF speech
processing is a superior system to the traditional AF clipping, AF compression, or RF
compression found in a typical HF transceiver for achieving the highest ratio of average-to-
peak power from an SSB transmitter.
• Increase average SSB power output by up to 6 dB
• Enhance readability by stations hearing your signal
• Break pileups for DXpeditions faster
• Keep your net or contest run frequency clearer
• Easy to install, easy to operate
The purpose of an RF speech processor is to increase the readability of your signal at the
other end of a QSO. Speech processors do not increase peak power; they increase average
power output. An up to 6 dB increase in average power output in SSB service can be
achieved with the proper use of a true RF speech processor like Ten-Tec model 715.
This power increase, coupled with the ability to tailor the speech passband can mean the
difference between a signal buried under band noise or an intelligible, copyable signal.
