Ive looked through alot of posts about the whister 1788 and its low volume. One subject I really wasnt able to find anything on was the use of a external speaker with it. How would I go about wiring that? Or is it even possible without voiding the warrenty? I really wouldnt to wire something directly to the board itself. I saw external speakers at radioshack that have plugs. Now would pluging a external speaker into the jack on the detector work and run it off batteries? I am highly doubting that idea will work though. Any comments would be helpful.
