OK, I answered my own question. You must do three continuous writes to
registers 07,08, & 09 WITHOUT reading them in between the writes.
This allowed me to change the frequency.

I ordered a 433 MHz RFM69HW but it came programmed to 915 MHz and will not let me change it.

The RFM69HW is marked "433 MHz" on the back, but when I read registers 07-09, is gives me 0xe4c000 which
comes out to 915 MHz. And it will not let me change registers 07 or 08. It will let me change the least
significant byte in register 09.

Did I receive the wrong board?
