This problem looks to me like the generator is on its way to die.
Maybe something simple like worn brushes.
 
Your battery might be charged intermittently. And your static in the radio 
comes from the weak battery.
 
Have someone check the generator/regulator.

You say it won't start. Do you crank and crank and the prop spins good for a 
while but it just won't start? If so the problem is probably mag related. If 
ignition system is breaking down will cause static. If the prop just doesn't 
turn (run down battery) it is alt-generator ( does the static sound like 
"wirling" sound and increase as you throttle up?). To check 
alternator-Generator. Check your battery voltage with a voltmeter (multimeter 
set for DC volts) between positive and negative posts before you start engine.  
Should be around 12 volts. Start engine and with RPM around 1800 check voltage 
again. Should show an increase, preferable at least 13.5 volts. Good luck,Bill

I feel like "pig pen" (if I have the Peanuts' cartoon reference correct) as 
there seems to be a black cloud following me around. I thought I knew what my 
radio problems were, but apparently I don't. On my first long cross country to 
Jean, NV, I attributed severe static on my radio to a failing battery. That 
seemed logic since the Coupe had a dead battery the next day and I didn't seem 
to have the same radio problems on the way back. In retrospect, that logic 
seems pretty weak.I started my trip to Wyoming to visit my father for 
Thanksgiving on yesterday. Guess what? Dead battery again. I replaced the 
battery with a loaner that was charged and known to be good. The Coupe started 
now and I did some touch and go practice to see if the ship was ship shape. I 
push the start of the trip out by one day and spent the rest of the day 
relaxing with my wife.This moring I departed just under the clouds from 
Torrance. After clearing the morning coastal gloom, I climbed to 9,500 MSL for 
my first leg to Kingman, AZ. (Man it takes a long time to get to 9,500 
feet!)Toward the last half of the trip I was noticing some static on the radio. 
I attributed to weak signals from distance airports on 122.8. But as I 
approached Kingman and started my chatter on the Unicom channel. It became 
apparent that everything was not right. The static was so bad that I could 
barely copy anyone's transmission. So I switched to my handheld radio, and it 
was no better. I warned Kingman traffic that I was having radio problems. When 
I entered the downwind, I was told that I was being heard loud and clear.After 
I landed (and stopped shaking), I powered down at the fuel pump. I turned the 
radio back on with the engine off and sure enough there was no static. The 
radio was loud and clear.So, here is my restated problem. On long flights, my 
radio reception becomes extremely staticy (is that a word?). At the being of 
flights and on short duration flights, everything is fine. I can only assume 
that static is being generated by the engine (I guess the alternator) or that 
some kind of static filter is failing when it heats up.Does any of this make 
sense?Oh by the way, my engine wouldn't start either. I guess I will be 
learning how to solo hand prop tomorrow morning.Stuck in Kingman...Frank
