Easy to assemble and worked fine without tweaking the pots from their 50% setting. Comments received on 2m SSB were that, while audio is sweeter without it, the difference in signal level is dramatic.

Apart from a lot of advantages that made the FT-81x transceivers one of the classic QRP rigs, the lack of power on SSB is well known. This compressor makes SSB workable and gives the FT-81x the punch it needs.

I had a 590 set-up with just a patch lead connected to it. A simple test but boy does it MAKE a difference transmitting on the 818ND with the processor on and off, a great deal of difference! It also feels as if the TX bandwidth is narrower with the processor in switched on.

Works as specified, a good product at a reasonable cost.

I received the kit very quickly and the construction went well. When tried on test equipment the FT817 showed a reasonable increase in average power.. I am happy with the unit and will go with me on a trip to NZ.

I got my speech compressor for ft817nd this morning over the moon with it thanks

The compressor seems to working well. I would suggest better guidelines/help for the interactive adjustment with mic gain in the 817, mic level in the compressor and compression level. There must be better guideline available for a standard step by step procedure. The case would be improved with two small holes suitable for a jewllers screwdriver for pot adjustment without splitting ithe case. The plastic taps on the RJ-45 plugs on the interconnect cable are very susceptible to damage and should be protected, they are a weak link in the design. Other than that, first reports are good and I am optomistic.

Brilliant little gizmo makes my 5 watts seem more

it is nessesary if you don’t want to keep your voice ...loud...it is useful ..
