KO Universe 3 interference problems

[RobW]

I know it is not easy to solve these things over the web but just thought it might be worth a shot in case someone comes up with something.

Have a KO Universe 3 which is probably about 5/6 years old. Have run it with Spektrum 2.4g from the start and never had any interference issues before about 2 months ago. Have one standard receiver and two micro ones – not sure of model (cars not with me at moment) but all bought at time of transmitter so not the very latest.

Started having a couple of issues at local track (TORCH – large-ish outdoor astro track) where it would glitch going around just one corner – not even the further one away. Did all the normal things like making sure transmitter battery was fully charged, moved receiver aerial and changed receiver. Usually resolved the issue.

Problem then started to get worse with car intermittently glitching and losing throttle for splits of seconds and then coming back. It is not continous – maybe once or twice a lap but enough to make the car dangerous to race. This was with 2 different cars (my 2 and 4 wd so different speedos, motors etc) and three different receivers so I figured it had to be transmitter related. It is not a loose module as I have always used insulation tape around the module to ensure a snug fit.

Borrowed a 40Mhz module half way through a meeting and problem solved. Thing is I want to run 2.4g so I got hold of another 2.4g module but still had the same problems. Borrowed a receiver capacitor and problem seemed to go away until my final when after I crossed the line (in first of course ) when the car carried on at the end of straight at full speed, luckily not hitting anyone.

So it seems transmitter has interference issues just with a 2.4g module fitted – is there any logic to this? Odd thing is the problem generally seems to start half way through races (never in practise) when everyone is stood around with their transmitters switched on ready for the next race – are the latest 2.4g systems stealing all the channels?

Any ideas?
