I recently got a APRS transmitter and tried it out today in the smart. Then things went south...
First about APRS. APRS is a combination of GPS and a ham radio transmitter. Basically it takes your location and sends out a packet of info out on a specific ham freq. Every two minutes it sends out a 10 watt signal.
This particular device fits in a small Pelican case, batteries and all.
After starting the smart, I turned it on when I was leaving work and put it up on the dash so the GPS could receive better. I put the car in gear and... no throttle. The engine was running fine. I shut off the car and tried again. The throttle was fine. Went down the street and about two minutes later, No throttle. Not good when the light turns green and car no move! I still had not put it together yet. Got to the store I was going to and the car was fine. I thought about what had just happened and the (APRS) tracker was the only change. Turned that tracker off! Now I had a yellow check engine light. I checked the scangauge and there were two codes. P1D00 and P1D01. I have not googled them yet.
Anywhoo... I was just two short blocks from the smart dealer and I went there. They are going to plug into the car tomorrow morning and let me know what is up. Good thing I still have my other vehicle. They gave me a ride home.
The only thing I can figure is that the "pulse" from the tracker on the dash overwhelmed... something under the dash. Hopefully they can just reset the light and I won't do this again!
I will let you know.
