Regarding suggestions to put a small speaker in the hole in the
HW-8's cover, be aware that:<br>
(1) You would have to add an audio amplifier PCB because a stock
HW-8 will not drive a speaker, it needs mono headphones</font><font

ohms nominal</font><font id="role_document" size="2"

(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).<br>
