Thank you Bruce,
As the BMW install instructions show that ground coming from the antenna cable what you say does make sense. I will certainly add this to the list to try. Since I already had the sting ray apart I went ahead and attached the ground to the chassis. Some have reported taking a small sheet metal screw and puting it thru one of the vent holes but there is a small green screw on the underside of the chassis which I used.
I had thought to run that ground wire to the same place where the antenna grounds go under the seat. I may try that before cutting into antenna cable.
Here is some info I ran across on the "squeal" (see the attachment in the next post):
How To Cure The Squeal
Refer to Figure 3.
1. Open the mike and figure out which colored wire is the actual audio or Mike line. (See the previous discussion to determine this.)
2. After finding the audio line, cut it at a convenient spot and insert a 4700 (4.7K, YELLOW-VIOLET-RED), 1/2-watt or 1/4-watt resistor in series with the audio line. See the inset in Figure 3.
3. For extra filtering protection, also connect a .001µF or .01µF ceramic disc capacitor from either side of your resistor/audio line connections to the bare twisted shield (Ground) braid of the mike cable.
We are getting there just takes time and great sharing of what has worked for others here. It was thrilling to have it work thru the VCII, helmet set and the bikes antenna if only with the cb's batteries for power. I am guessing to have about $60.00 in wire, plugs, soldering iron etc and tons of time and effort but that still beats the $495.00 plus install on the BMW radio that can not be gotten due to at my last check some 26 on back order for several months...
It still erks me that a cb on a motorcycle should not be this difficult. It has out a damper on my otherwise good feelings for the ride overall.
