    AM Radio Reception

    Not to beat this subject to death, but I shared with Grady my posts and observations above (see above for who Grady is) and this is what he said: The problem is actually pretty simple, probably stemming from having unshielded wiring and unfiltered goze-intas and comes-outas where the...

    AM Radio Reception

    Also, depending upon the resources that you want to put into this, you might want to consider hiring as a consultant Grady Moates out of Boston who has great knowledge of AM reception issues: http://www.loudandclean.com/. He can be reached at: [email protected] I have known Grady long...

    AM Radio Reception

    My main interest in all of my experimenttion with the OEM Alpine Roadster radio was the FM reception rather than the AM reception as I am not generally an AM listener although do enjoy it occasionally. So I did not delve as deeply into trying to improve the AM reception as I could have. If...

    AM Radio Reception

    When I first got my Roadster some 17 months ago, the radio reception issue drove me crazy. I represent radio broadcasters in my day job and therefore I have more than a passing interest in optimum automobile radio reception. Also, I was moving from owning a BMW in which the radio reception was...

    National Plug In Day 2012 Events - September 23rd

    NPID in Washington, DC Note the prime parking spots for the Model S and the Roadster! At first I told organizers that I would not give rides, but then I relented and produced a big TESLA smile!

    Roadster volume control

    Its gotta be the amp. I changed out the Alpine head unit to a Kenwood DNX-6990HD (so much better than the Alpine!). I still have the occasional substantial volume increase. Happens with the top down (sure that has nothing to do with it) but at a high volume from the head unit either with...

    Charging Station at General Lewis Inn, Lewisburg, WV

    The General Lewis Inn in Lewisburg, WV (Lewisburg WV Hotels ~ General Lewis Inn ~ 888.697.5902) is an excellent destination for a TESLA road trip as it now has a J1772 charging station. I had to be at the General Lewis Inn for a meeting with a small group of engineers last week so I emailed...

    Trip from Reston to General Lewis Inn, Lewisburg, WV -- I-81 Charging Info Needed

    Next week, we are taking a trip with my Roadster going the approximate 250 miles from Reston on I-66 west, I-81 south and I-64 west to Lewisburg, WV. I need a place to stop and charge somewhere on I-81 between I-66 and I-64, particularly on the return trip on Sunday. I see that PlugShare...

    Replacement of Alpine IVA-NAV-10

    I had not seen that Alpine unit (looks like it is a very new model) when I was looking for a replacement so it certainly looks like an option that might be worth considering. Below is the wiring diagram from the OEM Alpine to compare with the wiring harness diagram whenenver the installation...

    Replacement of Alpine IVA-NAV-10

    On my car there is also what appears to be a GPS antenna on the back of the instrument cluster (it is an approximate 1"x4" rectangle), but I was told by the TESLA techs that it is the GPS antenna for the car's monitoring system (the feature that tells the car at what current draw and when to...

    Replacement of Alpine IVA-NAV-10

    With the new crop of double-DIN navigation receivers being released early this year, I decided it was time to make the move to replace the Alpine IVA-NAV-10 in my Roadster 2.5. To say that I detested the Alpine would be an understatement as so much of it, in my view, was poorly designed...

    Latest double-din navigating car stereos for Roadster 2.5 Sport?

    If the conditions are either substantial changes in sound quality between the HD and analog FM, or time-shifting, it is not the radio. It is the radio station's implementation of the HD radio signal. Not only do many radio stations broadcasting in HD give very little attention to the technical...
