Any help greatly appreciated.

10Hz under your RF IIRC...

so if my rf is say 60 hz. then tune to 50?

anyone else got ideas?

my res. freq is 51hz, we usually need to tune around 40ish to peak at 51. Robert Kollar who competes in prostock USACi is tuned to something like 59 or 60 hz and burps at 63hz if i heard/remember what he said correctly. you will probably end up having to try many different freqs

start ~10hz below. cut off 1" each time and meter it, if you gain, cut again, once you stop gaining, dont cut anymore lol. with a regular slot port it might be hard to cut 1" off though.

^^^ that does not seem like a too exact of a method.
