If he is stuck on 136.550, it looks like he is using a Ropex Tx.
I have now modified two of them, that is installed a new crystal, which does
involve some major surgery. In addition, if one wants to be exactly on a
particular frequency (as we have to be with our FCC license: 136.750 +/- 7 Hz),
then some small adjustable capacitor must be inserted in series.
I would be glad to supply detailed instructions on the process to anyone
contemplating the re-crystallization (?) of a Ropex.
