OK, give that a go and with any luck the Colt will actually turn out to be roughly as sensitive as the 777 now.

If not, the fact that the front end coils needed retuning means that we can't now assume that any of the tuning is still correctly set, so it may be necessary to check the I.F section tuning as well. Prior to that, you first need to be sure that the channel frequencies are dead on.

Do you have enough TX output on all bands (AM/FM) to allow you to measure the TX frequency?
