| Before the antenna system setup change the Orion hardware mic gain was set to 10dB and mic gain set to 100. Still my ALC led faded away at times (not always) and it was frustrating. Stations reported my audio sounded raw and to much low frequency audio. I blamed the microphone at that moment. My solution was to move the TX EQ low pass to a higher value and this sounded better according to responding stations. Same experience when using the rear connector, connecting through 600:600 ohm audio transformer, Behringer voice optimizer and the same Heil PR-781 microphone. The result was still raw sounding audio. Stations did not complain but I did not get any compliments for great audio either. | Before the antenna system setup change the Orion hardware mic gain was set to 10dB and mic gain set to 100.

| - | After the change the Orion started to behave like it should according the manual. The hardware mic gain set to 0 db and the mic gain is around 80 now. ALC led is lively following my voice at all times. Stations report and compliment on audio quality. Speech processor can be set to level 9 and the Orion keeps working like expected. Right now I am using the speech processor at level 6 and it really works well. | + | After the change the Orion started to behave like it should according the manual.
