my radio was working fine then it started to pop thru the speaker .then it went farther downhill.I did not have channels 1 thru 21.it would still trans on 22 thru 40 and the mod channels and hear .now the added freq counter scans thru all the freqs. and will not trans or receive.if some one close talks it will pick them up and stop scanning until the unkey then scan again.checked all the votage points 1 thru 15 and the only bad one is #7 test point which should be around 7 volts.it only has .18 volts.I have gone thru the hole curcuit and can not find any thing bad.r 152 the votage in is 8.54 volts and when you hook up the resistor it dops to .18 volts out.has 7.50 before hookup.trans 32 is good and I also changed the pll.checked all cap and resitors in the curcuit.the is a static charge somewhere because when its powered on the s meter will slowly peg out.turn the power off and the needle will slowly drop back to zero.anyone at all that has any idea I will try it thanks Sonoma. |
