- My Magnum Sport instructions said the same thing. Well, it's not quite
- the case that they would actually adjust the crystals; perhaps they
- are implying that the would tune some circuitry or something. At any
- rate, the common and effective practice of just pulling out crystal#1
- and substituting crystal#2 seems to have given nary a problem to me
- and to any racers who find that they need to use an alternate frequency
- in an A-main due to conflict with another racer. In short, I personally
- would disregard this particular Futabian instruction.
-
- Regarding my earlier post which asked if AM and FM crystals are the same
- thing with different prices, if I ever get an FM radio, I will certainly
- try 'AM' crystals before I pay the 'FM' crytstal price.

- Stay tuned,
