My plates are K5GP. Www.egpreston.com/Tesla3.PDFLooks great. I'll only rate 5 stars if you have the licence plate to match.

Great info on the long distance trip, I’m planning a trip from San Diego to Las Vegas on April 30th making 2 Supercharger stops. One stop in Fontana Ca and the other in Baker Ca. Model 3 plus 240 mile range.

I can see the cable now, so this must be the 2 m antenna.
I was confused because you mentioned just above that you installed a 10 m antenna?
So I was expecting having a tuning coil at the base, that you might have then kept hidden under the trunk door...
Where did you then installed the 10 m antenna? Do you have any pics?
Note: In case you might consider installing a 12 V power line in your trunk for an amplifier or other tools,
I noticed the following video explaining how to put a wire connected directly to the battery (see from 7:48 to 12:00)

I had another ham show me his setup in a Model S. Mounted the head on the "Piano Black" trim on dash. The antenna used was a glue mount base with a PL259 connector RG316 cable. I placed the mount on the quarter glass left rear window. I did have wind noise from it. Unfortunately I never got to use it. I went overseas for 6 to 8 months, career change (retirement) and marriage. I moved to DU land....Pictures are missing.

I have the plates on but am getting rid of them.
Ohio instituted a $200/Yr EV registration fee and I can't do a multiyear registration on Ham plates because they want to see your license every year. So I went back to regular plates to do a 5 year registration before the fees go into effect. I'll get some kind of plate cover with my call sign

I have a separate 5" mag mount for a small HF antenna. It's a little ugly, so I only put it on when I need it.
FWIW. I got the 8.6.1 update last night and immediately got a "Low USB voltage" warning from my scanner.
Tesla is apparently messing around with the current limit on the USB outlets as evidenced by others complaining that their wireless charging pads quit working after the software update.
I moved the scanner to another USB that wasn't shared with a thumb drive and it seems to work.
I'd be curious if anyone has measured the current draw before and after.

I put an ammeter on it and it stayed below 10.1 Amps on FM.
Two anomalies though:
1. On 440, the charge door opens when you transmit. This was stationary, don't know if it would when in motion.
2. I could hear some white noise on the FM broadcast receiver when transmitting.
3. I had the 12V power to the outlet go off for several hours with no error messages. I chatted with Tesla and they didn't see anything but it then it came back on. Reboot had no effect. Rather disconcerting. I have seen another post that said the circuit may reset after 60-90 minutes after a fault is removed but I wasn't close to the 12A continuous limit (and I had fuses inline). It seems like it went off while I was away from the car and not transmitting.
Current Draw FM: 2 and 440 measured at the socket
Receive only 13.91V .63A
10% 13.46V 4.65A
50% 13.11V 7.74A
100% 12.85V 10.11A

Hey! The TMC forum is huge, but I think I finally found my people!
Follow up:
I got some RFI around 146 MHz and discovered that the wireless charging pad was creating it.
It doesn't matter if the phone is charging.
All I can do at this point is unplug the wireless pad when using the radio.
FYI it's the JEDA wireless charging pad. (the latest one without the data wires)
If anyone has experience with Nomad and has different RFI results, please advise. I suspect it is just generic to wireless charging.

Update:
JEDA confirmed that they have an RFI problem on "some" units. I thought I even noticed something on FM broadcast for weak stations, but I may be wrong. I don't know how they passed their FCC certification.
I bought the $20 ultra slim wireless charger from Amazon and it works well with no RFI. I had to cut off one of the backside bumps on the stock pad to cut the distance down for a phone with a case.

I am really getting a lot of RFI with my 2meter rig. The ammount of noise from the motor is really desensitizing my radio. Always looking for solutions!
Exact setup I have. Speaker hidden under glovebox. You don't get interference with the glass mount? I went with a lip mount to be safe but I've always liked the larsen glass mounts.
My next project is to put in an HF with a screwdriver antenna... but not sure about rear trunk lip mounting it.

Hey Bob, yes, it can be done. You have two options, the senter mount hitch, or custom make a side mount (just weld a 2" square to shoot off to the side with a second hitch) this allows hitch use while the antenna is mounted. That said, I have discovered the Comet HD series mounts work just fine for small - medium screwdrivers.
Hope that helps. 73's

Many more then you would think. Not hard to install with a good radio shop. The main trick is be sure to use a relay off the ACC and 12V battery, then you are golden.
