frsky conversion help

[Alan Reeves]

I have a ko esprit type r fitted with the v8ht hack module and using the v8r4 receiver.

The problem is they take upto or over a minute now to find each other.
If I leave the transmitter on I can switch the car on and off no problem but if I switch the transmitter off it can take an age to come back online.
When I first converted this set the response was instant.
I have tried re-binding to no avail.

Any ideas what has gone wrong? I have reverted to 40meg for the time being...
