I have a small solar system that charges L1 nicely. Problem is I need to back down on the charge rate when a cloud comes over. It seems logical to do this through software but Elon choose not to allow this. So based on the conversation on this thread I will proceed with the openEVSE route...

Its very hard to get off fossil fuels even with nuclear in the mix and next to impossible without some nuclear because of the large storage requirements and lack of power lines to power a renewables only plan. I have some models on my web page showing this if you want to get in to modeling up...

I was wondering if the car charges to 99% of battery capacity does that mean the battery contains 99% of the original 100% energy in a new battery? If so my battery degradation would be just a loss of 3 miles from 310 miles. Now that I am charging a bit at a time with covid and im not going...

Its too large for my garage. Im not buying one until its shrunk in size.

I wish we had a way to take grid tied panels with inverters on each panel that make AC and be able to plug them into a box that would allow us to plug those panels into the Tesla EV even if we do not own a power wall. This would be a way to extract energy into the car off grid or when the grid...

A great HF affordable radio is the ICom 7300. I got one for my daughter for xmas. I've been wanting to build a small cw transmitter to go with my IC756P3 which has a good RX but the TX is burned out. I have no specific suggestions for you. I see others are commenting. Maybe one of them...

Running cables to the 12 volt battery would have required drilling holes. Another ham said there is access to even higher power levels at 12 volts under the rear seat, enough to run nearly a kW. This is beyond my interest level. I was just wanting to get HF and VHF radios on the air in the...

Some local Tesla X and S owners are saying they are getting AM noise. I did some more testing. This morning I took my Yacht Boy portable receiver out to the car which was powered down. I tuned in a local radio station on 590 and it was full scale on the S meter. I tuned up to 605 kHz and...

I made one last video of my final no holes drilled installation in the Model 3. Most importantly it's wife accepted. https://www.youtube.com/watch?v=X8dmpqsuqq8 The repeater background noise was due to a high audio volume, not car RFI. Most of the time I'll have the FT8100 radio off and...

I switched to 2 meters and trimmed the little 1/4 wave whip to get a low swr. It keyed up local repeaters however there was quite a lot of background noise. It sounded like switching noise to me. I spend the afternoon moving the antenna to the back trunk. There was a wide enough gap to...

This morning I qso'd KA8KCR and W4EDE both in Florida from my home in Austin TX as /m using the above video link setup. I was lite copy for them but I was running just the little whip at 25 watts on 7057 kHz. KA8KCR Richard told me he has a friend with a new truck and ham radio in the truck...

That one drive link was not very user friendly. I made a youtube video. Teslas make ideal ham radio vehicles on high frequency with the transmitter RF not causing interference to the car's electronics. The Teslas may be the only cars this well shielded. See

I put my ATAS100 Yaesu mobile mount on the front hood and powered up the IC7100 on 7038 hz. There was no rfi. I found I could run 25 watts with 11 amps peak current on the 12 volt accessory plug. Here is a short video Meet Google Drive – One place for all your files

What brand and model of mag mount antenna are you using? It's tiny, just what my xyl wants. I just bought an IC7100 so now Im getting serious about installing it in the model 3. How did you route the 12 V power and control cables to the trunk? 73 gene k5gp

What if you polish it so its a mirror finish?
