Mike’s RadioShack Model 2000669 modification to prevent station memory loss

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.

Many thanks for creating and documenting this simple mod, Mike!

On a side note, I remember when RadioShack used to pride themselves on having a full line of products that could maintain memory if batteries were removed or in case of power outage. RadioShack badged VCRs, receivers, radios and clocks all had this feature in the 1990s, at least.

Again, Mike, many thanks!
