1. No AVC means you constantly have to crank the volume up and down as you tune weak and strong stations.
2. Audio quality is poor compared to newer sets, by the mid 30s things were WAY better. Speakers and audio transformers improved massively.
3. Easily overloaded by strong local stations.
All in all, those sets made before approximately 1935 are much more primitive than those produced later.
Some of the major improvements include:
AVC
VARIABLE MU RF tubes
Beam power output tubes
Dynamic speakers with accordian spiders instead of the terrible phenolic spider
Better power supply filtering via inexpensive electrolytic capacitors
The pentagrid converter
Also, by the late 1930s, components such as resistors and capacitors started to take on the physical appearance which we know them by today. The really old stuff looks very weird when you're working on it
Finally, the art deco movement of the 1930s dramatically improved the styling of radios, modernizing them substantially compared with earlier offerings.
And on and on.
