Ron,
Regarding suggestions to put a small speaker in the hole in the 
HW-8's cover, be aware that:
(1)  You would have to add an audio amplifier PCB because a stock 
HW-8 will not drive a speaker, it needs mono headphones, 1000 ohms 
nominal;
(2)  The direct-conversion receiver suffers from microphonics - any 
vibration or even touching the case is loudly heard in the 
headphones. Perhaps an external amplified speaker could work if it's 
not loud, not located close to the HW-8, and is not acoustically 
coupled to it (like sitting on the same shelf).
