Custom Packaged (tru)SDX
Posted: 24 May 2022, 02:27
My requirements for this great rig are likely different from most. I dont require a tiny rig but rather wanted to have an internal rechargeable battery (1800mAH), lighted pushbuttons (for night time use), larger speaker with more volume and better bass response, and a dedicated AF Gain control. I also machined a small shroud for the readout to make it a little better viewable in sun light.
I added a small LM386 gain stage and that allowed for the larger speaker and the AF Gain control. The shown front panel is temporary- just to determine how everything would fit. The LED pushbuttons only added 2mA drain and the LM386 another 18mA.
