Can a 72 Mhz receiver use a 75 Mhz crystal?

[BoyntonStu]

How flexible are receivers to using different freq crystals?

I would like to use a VEX 75 Mhz FM PPM TX sending to a 72 PPM
receiver with a 75 crystal plugged in.

I have never done this!!
And i think that it will not work,if i remember right!
The cost for a crystal is to little(almost 10$)...

QTY:Frequency/Band Changes:
Receiver (only) frequency change: $20.00
(Within the same band) Receiver (only) band change (except R127DF/DP
and R138DP receivers): $20.00
(72 to 75 mhz OR 75 to 72 mhz only) Transmitter (only) frequency
change: $20.00
(Within the same band) Transmitter (only) band change: $20.00
(72 to 75 mhz OR 75 to 72 mhz only) Non-PCM Transmitter mode change:
$20.00
PCM Transmitter mode change: $30.00
Transmitter module (only) frequency change: $20.00
(Within the same band)
or you may wish to simply purchase a new module from your hobby dealer

What does Hobby Services do to a 72 Mhz Futaba Receiver in order for
it to work on 75Mhz?

Normally you adjust a component to "tune" the circuit to a set frequency
a bit like tuning a guitar but you need several pieces of test equipment
to do it
