Here's the "original" mount:
because of the assembly type there was some vibration against the box and sound was a little bit on the bass side.
Nothing some rubber washers and a little of fabric can't solve, there's also some peaces of rubber, bellow the speaker in each of the bolts, from an bicycle inner tube
I also increased size of the lid holes...
To finish product:
Now the sound it's much more even across the spectrum (2.4Khz!) and doesn't "vibrate" against the box lid.
Still to do on the radio:
*Add 30,20,15,12 and 10m band...and maybe 500Khz rx
*Add another audio amp, the existing one stays just for headphones
* Add in IF buffered output
*Check drive level on 40m that is generating some instability (I know were the problem is and how to work around but will try to fix first)
And eventually I will transform the "Speaky" in something similar to this:
p.s. The magic smoke of previous post was not that magic, it was a broken solder joint in one of the pins, glad it was simple because it was not going to be easy to replace any other components in the main board.
Have a nice weekend!
