Compressor

[brandon7861]

I never studied compressors, but I saw this video and thought it would be fun to try. I only had single op-amps but the plans call for two duals and a quad. Slapped some uv mask on the traces, still don't know why i do that, just makes it a mess. I still need to get the pots and a metal enclosure.

This is going to be one of the two boards for my home brew desk mic. I have no idea how well this will work for voice but I thought it would be worth a try.

For voice I would suggest DSB clipper: https://www.pa0fri.com/Diversen/DSBclipper/dsb-clipper.eng.htm
I've built a few of them, work miracles.

This the basic design found in the Yaesu FT-101 radio before inflation made them leave it out from the "EE" models. Processing the RF signal is more effective than processing the audio.

I have built several different style compressor/processors, even sold some to locals that used quad op amps back when I was at school (long time back),
I have built them using discrete transistors & vogad IC's too,

Imho RF type clippers that operate on the principles seen on pa0fri.com out perform any audio based clipper/limiter type speech processor,

They can sound thin if the filter you use is narrow or you use a sharp crystal filter but they give your low power radio a BIG readability boost in a pileup.
