While speech processors can make a difference getting through the QRM, they can cause unnatural sounding voice audio and should not be used when chatting locally. S1 provides an easy on/off switch for the speech processor during the local rag chew. This circuit can be easily constructed on any universal PC or perf board and should be housed in some

FT817 Audio Speech Processor. vk3bq / May 16, 2014. I blame Ben, VK2BEN for making me spend all my money, the other week, he shared with me a link to the below Speech Compressor designed to fit inside a Yaesu MH-31a8j microphone supplied with the FT817 radios. The ft817 has no built in speech compressor function, and this little PCB is designed to add a lifte more …
Audio Speech Compressor – Electronic Circuit Diagram
https://freecircuitdiagram.com/2257-audio-speech-compressor/
Speech processing is an important thing, when the SSB is operated at low power to get through the QRM. Speech processing can be done by this circuit. This is a simple and low cost circuit but it can perform well. This circuit includes the microphone element. So, we can assemble complete speech processor microphone in an old defunct desk mike. Here is the schematic diagram of …

https://www.electroschematics.com/speech-processor-clipping-and-dynamic-compression/
Speech Processor Circuit. To obtain the best modulation result of a transmitter you can use 2 ways: clipping and dynamic compression. Both methods have disadvantages: clipping – there is no constant signal carrier and so the transmitter has a tendency to be overmodulated or undermodulated and in dynamic compression degradation also happens because of the …

The Audio Processor system is a combined software and multichannel hardware system which applies real-time DSP effects to audio and acoustic applications. The system uses one of several DSP/data acquisition hardware possibilities to apply real-time processing to multichannel analog input, and produce desired analog output.
RF Speech Processor - Model 715
https://www.tentec.com/rf-speech-processor-model-715/
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 …

The processor is powered from the radio s main +13.8 VDC source. D3 is a 6.2 volt Zener diode that provides a well regulated power source to the processor. RF is decoupled from the DC power supply by C1. Holes are included on the circuit board for extra filter capacitors CF1 and CF2 (dotted lines). For RF filtering, CF1 can be
Compressor – Electronic Circuit Diagram
https://freecircuitdiagram.com/tag/compressor/
This is a speech processor circuit that can be used in communication radio circuit. This circuit consist of two sections, they are amplification and compression or dipping. The combination of these processing will improve the SSB communication intelligibility and provide higher average level while avoiding clipping.
