Yes to both questions.

I would offer a minor spelling correction ('receiver' as opposed to
'reiceiver'), and I would also say that 29.05 is only one example of an
IF. It is by no means standard across all receivers.

Example: Motorola has used IF's of 45MHz, 10.7MHz, and 17.9MHz in
various land/mobile 2-way radio products. GE/Ericsson has used 10.7, and
many others.

There are still other receivers that use more than one IF (dual-
conversion or triple-conversion).

Happy reading.
