This is a follow-up to my mini-review of the new Radio Shack model 2000669 receiver.

Overall, I continue to be quite happy with this receiver, however, I think the loss of memories and time when replacing batteries is annoying.

So, I did a simple mod to the radio to help prevent having to re-program everything after installing new batteries.

I found that there was enough space within the case to tack a 220 µF 6.3 V electrolytic capacitor across the pads on the PC board where the battery leads are attached [see the photo below]. Adding a series resistor to limit current flow might be better, but this simple change seems to be OK.

The mod won’t prevent long-term memory loss, but it will keep enough voltage on the circuit for a quick battery change (especially if you change one battery at a time). The radio is not actually altered, and the mod can be easily removed if desired.
