Brooke An interesting question and like you I have seen the odd frequencies. For the 10.230 MHz since they come out exactly at the carrier frequency that would tend to speak to a direct conversion receiver.
At least on the much older receivers that had IF stages at either 75 Mhz or 35 Mhz and therefore some other frequency would be needed. (There could also be a very wide range of IF frequencies besides the two I mention.) I will guess the 10.9 Mhz is exactly that when multiplied up either comes up high or low by the IF frequency offset they wanted.
