spekky module issue

[fidspeed]

hi experts

have a spekky module in my sanwa M8 it is very slow to illuminate green light on back of module (not trying to connect to rx at this point) it vaires between 5 and 45 seconds (worse at a race meeting )

i have just bought a ko spekky module (both pro versions) and this is super rapid

any thoughts ? (pins contacts are good and tight)

regards dave
