| Post subject: | Low Khz deviation |
On my first (very brief) test using ST to drive my transmitter, I could only max out at 32 Khz deviation. I've bumped the Marian Trace Alpha output from +15 to +18 dBu. Where else shall I look? |

Probably exciter input level. |

If you mean the transmitter itself, I tried that, didn't do much... |

Success! I increased the MTA input (Analog 1-2) +7.5; all faders at zero; then had to turn my transmitter level up by "5" CW to get from 50 khz to 75 khz. For the record: running ST 7.74 beta027, preset: Analog Pleasure FM (hvz), into BW transmitter TX300 v2. |

Odd, even with my Realtek (which is probably much softer than the Marian) I need to lower the level to about 30% (-10 dB or so). RVR LCD30. |

it makes me wonder if my air chain is a little on the soft side... but this was recommended going into my audio switcher. For the record, my airchain for testing ST was Rivendell automation -> ASI 6044 card -> BT switcher -> Behringer SPL 3220 (limiter bypass) -> Henry Patchbox -> Marian Trace Alpha -> ST as above. Only the Behringer and MTA are easily adjustable (not counting ST), and the Behringer is pretty straightforward. |
