- There are some manufacturers - try Ace R/C, look in most any R/C oriented
- magazine for a number/address. I seem to recall the product is called
- "Glitch Buster", but that might be another mfgr. Every now and then someone
- in the magazines brings up the subject - Don Lowe of RCM (AMA prez) has
- written several articles about it, I think - he even went so far as to
- solder capacitors across the signal/ground wires RIGHT IN THE RECEIVER!
-
- I can't say for sure, but I think if you solder a small cap between the
- signal and the ground lines fairly close to the receiver, it will greatly
- reduce this problem. Best bet is to call someone like KMI (Kraft Midwest)
- and ask them for specific details. If you're willing to do the splice/solder/
- heatshrink routine, it's cheaper than buying a commercial product, which
- does the same thing.
-
- Unfortunately (fortunately!) I haven't needed to do this, so i haven't
- tried it. But I religeously read just about every article in both MAN and
- RCM, so i recall seeing this many times.
-
- Good luck!!
