With the use of high pressure injectors it takes a 100V pulse to actually fire the injector. There is also some back EMF from the solenoids as the pulse ends and the solenoid opens. Unfortunately the
I will point out that I am not publicizing the specific information I have on BPL locations, for pretty obvious reasons. Those hams that are willing and able to help should do so through the local am
Well, I guess you are now a hindrance instead of a help now, too, Tom. :-) To some I might seem like a hindrance, but I do have a point to make. It's bad enough when we don't appear technically astut
If you've arranged for local hams to cover every active and imminently active BPL pilot, then my criticism was indeed incorrect. Is there a similar effort aimed at hams working for public service age
Thanks, Tom. Are the frequencies in use likely to be compromised by BPL?>> Yes, if they have things running that are in the 40-50MHz range. That's the approximate frequency band we use for communicat
