I have to disagree with you there. I have just looked at the documentation for a
couple of the Radio Shack tape recorders commonly used with TRS80s, and
both have automatic gain control on recording.

It is actually quite rare to see a simple portable cassette recorder which
doesn't have automatic gain control (automatic level control). The early
Philips machines like the EL3300 are the only ones I've come across.
