The current QMX SSB receiver can receive AM because what is transmitted is the two sidebands and a carrier but it's not receiving it as AM, it's receiving as SSB using one sideband of the AM signal and ignoring the other sideband and the carrier.? You don't get the advantages of true AM reception where precise tuning is not required, and you have thrown away half of the data.

Try it with a rig that can receive SSB and true AM on a broadcast AM signal.? You will see that the AM signal can be received as SSB but you need precise tuning to get the correct tone, with AN you don't need precise tuning and the signal to noise is a little better.
