Default Help - Sanwa Interference - stumped...

I run a Sanwa Super Exzes with a Sanwa TM-221DS Module.
Never had any issues with it - ever - until today at Southport.

This last weekend at Southport outdoor track, I was occasionally a passenger as the car locked for a few seconds at full throttle and I had no control. Just like the good old days of interference on 40 Meg Had to retire the car in the last final as it was a liability and shot across the track into the straight

This is the TX.



And this is the Module



I tried 2 different receivers at the track, same problem.
I tried re-routing all the wiring and standing the aerial wire up, still no good.

Anyone any bright ideas?

The battery I normally run is a NIMH and reads out as 10.7 Volts on the TX. I wondered when I got home if the battery wasn't giving enough power / my signal getting swamped etc? With a lipo in the TX (blue Turnigy one in picture) I get a readout of 12.1 Volts. Is more Volts / power better?

I didn't try the lipo at the meeting as I didn't have it with me - could more power help?

Is the Southport track notorious for Interference, I did see others with similar problems, which is weird as I thought we had put all this interference behind us.

Any help - pointers appreciated.
