    Subject: SL-30 problem - on to the next phase
    Thanks to those that responded to the initial post. Looks like reseating everything got things working - now I need to learn what it does and how to use it. Here's my configuration: S-Tec 30 dual axis autopilot with GPSS steering module. Century NSD 1000 HSI SL30 GNC420W Anyone else out there with a similar configuration? I am now able to get the SL30 NAV portion to display on the NSD 1000 which sends the signal to the GPSS module for tracking and I can get it to turn using the needle pointer. It doesn't seem to track very well in either the LO-TRK or HI-TRK modes. After getting back from my test flight and reading...the manual says something to the effect of starting within 10 degrees of the selected radial and within one needle-width before engaging either of the TRK modes. I didn't get this close before engaging the LO-TRK and it didn't seem to track well at all. Is it really that sensitive in the setup requirement? Does it really track well if it is set-up properly first? Following a GPS course is really tight and I am really happy with that feature - it does a real good job with the set-up and intercept all by itself. I am hoping that the VOR/LOC tracking is as good...even if I have to set it up first. As before, your input is appreciated, Ralph RV6A N822AR @ N06 31.8 hrs

    Subject: Radio Noise
    I have a bunch of noise in my headset, which is not ambient noise.- I hav e isolated it to the regulator and/or alternator.- I built a SeaRey with a 912 UL Rotax engine which has an intenral alternator.- I would have pre ferred to use one of the Radio Shack filters but they are off the market. - Is there a good substitute?- Ameriking?
