[Elecraft] Revisting audio after absence from the reflector

[Henry Gardiner]

>  For my GMT logging, at Walmart I bought an LCD alarm clock with big 
> numbers for time and date.  Too bad there's no stock number on 
> it.  Placing the clock on the K2 top cover just behind the speaker grill, 
> I discovered a couple db increase in audio and a flattening of audio 
> response near the CW tone frequency.  It was easier to hear CW.  A better 
> acoustic match?  Blocked reflections from the wall behind?
>   Experimentally the effect can be replicated with cupped hands or other 
> objects to suggest a design for a simple reflector/horn made of wood.
