I have some unneeded scanner crystals I would like to swap for some
I need.

Here's the crystals I have:
(IF = 10.7 (Realistic)

453.100
453.450
453.600
453.775
453.975
460.350 (2 of them)
154.310
155.341
155.280

Looking for:
(with IF = 10.7 for Realistic)

146.520
162.550
for starters . . .

What have you?
