Last hijack post. Sorry Bjorn. Big fan here.
The noise you hear is interference caused by the type of radio transmission (the modulation technique) by mobile phones which use TDMA. GSM's radio interface (2G, if you will) uses it. IS-95 (aka CDMA) and UMTS (3G) do not (they both use CDMA).
If you have a Verizon or Sprint phone, you'll never reproduce it. If you have a T-Mobile or AT&T phone it will happen when you first power on your phone close to a speaker, or, if you lose "3G" and it falls back to 2G. Once your phone establishes the faster CDMA based 3G connection, you won't get any interference noise.
Based on my feedbacks, I will still keep poting on different forums as well as on Facebook. But mobile upload pics will only be posted on Facebook because it's easier.
About the GSM issue, don't worry about posting in here. It's related to my videos. In some of my raw video clips, they were so bad that I had to discard them. So finding a solution to this would be of great value not only for me but for others too

Try this, Bjorn. I think you have a Galaxy of some sort:
How to Force Galaxy W (Android 4.2.2) to Use Only 3G? - xda-developers
That is supposed to force your phone to select WCDMA networks only. Of course, it could also be your Model S transmitting on GSM which could be causing the noise.
This weekend I'm going to drive on the Green Highway (Green Highway | Green Highway Ett samspel mellan Sundsvall, Östersund och Trondheim). This is a collaboration between the municipalities of Trondheim, Östersund and Sundsvall. The highway goes from the west coast in Trondheim to the east coast in Sundsvall. There are several charging stations there, including 22 kW type 2 chargers that I will be using. Almost all chargers are free.
As of today, the 22 kW chargers only extend from Trondheim to Östersund. The last strech to Sundsvall is not yet covered. But by 2015 it will. And because I have limited time this weekend, I will only drive to Östersund and back.
It's going to be as low as -20°C/-4°F between Lillehammer and Dombås on Friday. But I don't worry too much. I've made some modifications to my Tesla to deal with that

Thank you for the tip. In several parts of Norway, including in buildings in Oslo, I need to use EDGE. So I can't switch to use 3G only.

Thanks for the explanation. I noticed it was a lot more common on my old flip phone (2G). But you're right, I can't get this to happen with my iPhone on LTE.

Hey techMology this makes sense to me. I drive a lot in areas with somewhat questionable cell coverage. Pretty good in general but definitely some spots no so much, so this totally could make sense. I think I am losing 3G and going into to 2G. There is one road in particular where I can almost consistently reproduce this problem. Enough so that I may mention it on my next service call as it is not *that far* away from the Palo Alto service center. I do have an AT&T phone. In general, I used to like Verizon, but I like the new cheaper plans that AT&T has now.
Bjorn - maybe you can turn off your 2G capabilities while you are making critical parts of the video, and then turn it back on during long non-filming parts of your drive.

Thanks for the tip. I think I'll just put my phone on flight mode before any critical recordings.
Now, a new video from me:

There were some changes in my plan. But I did drive on the Green Highway. Video will be published soon

Bjørn, I read in another forum thread that the easiest way to keep the heater going in the Model S while you are sleeping in it is to put the car in neutral with the parking brake on and leave the heater on the setting you want. Seems like you are having to wake up and reset the heater with your phone app. Have you ever tried the other way? Probably want a rock or something to chock the tires.
Thank you for the tip
I will try this on a flat surface with some rocks on the wheels just to be sure.Video #4 is out! This time I go to a Tesla gathering in Trondheim and drive the Green Highway which goes from Trondheim to Sundsvall.

Bjorn: As always, I really enjoyed your latest video!!! Gotta tell you I was actually perspiring watching you "drift" a little down that narrow highway early in the video - and the sound of the car and motor only added to the tension! really appreciate you showing us the different chargers and configurations - quite educational. Noticed at one point you were charging at 26 amps 9which is what you set as your limit), but the charger had 31-32 amps it was putting out. might want to be sure you are not artificially limiting charging by setting too low of a charging limit. enjoyed the sheer joy you showed at the Tesla meetup - many of us have shared that same feeling!! Lastly, noticed for most of the video you were wearing long sleeves - guess you only do that when it is colder than -15C! Jim

and again Bjorn, great video! Thanks for sharing! I have a question regarding the 90% charge. Why is the range showing 348km (twice in this video)? I would have thought that 90% charge would be at least 50km more than that. How is this range calculated actually, is it based on previous consumption or what?
Norway's scenery is just awesome, I love your drives during daytime... And thanks to your great videos, I was recently inspired to search for more Norway videos. I stumbled upon and actually watched yesterday a documentary called a Norway Passage from PBS, about Nordnorge ship and the live tv show from 2011, about the one-week cruise along Norway's coast.... The scenery is just breathtaking... Norway is such a beautiful country!
Take care and keep'em coming!

@jthompson: no, 26amps is the max at the moment in europe! tesla limited the current because of a hardware problem with the chargers. a fix is coming in 6-8
weeks
@atc@lwsk: the European cars calculate the range different than the US cars. Typical Range is based around 205wh/km which is much more realistic!

Thanks ch_model_s.
According to typical range of 205wh/km, 205wh/km x 348km = 71,34kwh
and 90% charge of 85kwh = 76.5kwh
Am I missing something? Or is typical range based on 220wh/km? in which case 90% charge which equals to 76.5kwh would give 348km of typical range.
That seems way off of the 502km rated by NEDC, what am I missing?
Thanks

Regarding 3G interference: It seems to be particularly bad when the cell phone is placed below the 17" screen. By putting it elsewhere -- e.g., in your pants or in the cup holders or even in the center space but next to the arm rests rather than in or under the cubby -- you may be able to completely eliminate the interference sound, at least from the car. Of course, if the interference is with the camera rather than with the car, these tricks probably don't make any difference.
Hi Bjorn,
Try gluing Coreflute plastic to the upper surface of your insulation material to prevent it from sagging.
I would cut a piece about 50-70 mm smaller than the pano roof opening to allow you to tuck the insulation in.
Coreflute is used for sign making and is often available free after an election as many politicians use for their "vote for me" signs.
