Wendy - re your post #85. So you've successfully removed the coil - and several times too. From memory of the RF box ass'y., I thought that doing that would be a really tricky job - and perhaps it was - so well done!
When the coil is out, do you have the kit to measure its inductance? Knowing that value and the value of the capacitors associated with it will enable the tuning range to be calculated, albeit approximately.
