Hi all,
I have just finished testing and tuning my DYC-817+FT-817ND.
I transmitted with 500mW into the endfed wire at the balcony and received with my IC-706MKIIG with no antenna at the shack. I was listening to my own modulation being received by the IC-706 on my AKG K240DF Studio-Monitor headphones.
There was a problem of too much mic gain on the FT-817, which was fine for use with the standard microphone alone, but it entered, at some point, in conflict with the Speech Compressor.
I reduced MIC SSB value on the FT-817ND from 90 down to 20 and then increased it up to 30, 40 and finally 50. I also had to slightly reduce the level of compression by tuning one of the Speech Compressor trimmers to avoid some audio interruptions I was experiencing while counting numbers, more precisely after pronouncing certain sounds, like the S at the end of DOS = number 2 in Spanish and TRES = number 3 in Spanish.
The modulation is definitely more punchy with the Speech Compressor ON.
After this tunning made while transmitting with 500mW, I switched to 5W and noticed that the output power peaks got higher with the Speech Compressor ON.
I think it’s got much better now and I’ll try to run a new comparison test with and without compressor during my next activation. Not today because it’s raining here…
That’s all folks!

P.D. after many times switching between positions 1 and 2 in the switch at the back of the standard FT-817 microphone, I must admit that I almost don’t see any difference. Perhaps, my voice gets less bass and more treble sound on position 1, but it’s been really difficult (rather impossible) for me to appreciate a substantial difference.
