But I thought I would be able to get the aircraft bands and it does not
go that low. Plus one thing I read said the mods allowed you to tx but
not rx those frequencies. I am confused!



Your Alinco radio is FM only. Aircraft only transmit AM, so even if
your radio could be made to tune down to the aircraft frequencies, it
still could not hear (detect) aircraft radio traffic.

You apparently mis-read the "mods" information. No mod I ever heard
of would allow you to "TX" and NOT Receive. That wouldn't even make
sense. Probably you meant, receive only, without transmitting, which
would be just fine as you don't want to transmit out of the ham band,
anyway.
