    SDS100/SDS200: SDS100 Battery Hack for Record/Play

    I know there's a lot of discussion in other threads on the SDS-100 battery but I didn't think any of it focused on a possible workaround for the fact that the radio will not record without the battery pack. Has anyone looked into what would need to be provided from a battery pack substitute to...

    BCD536HP Date and Time reset.

    OK, I know the Clock Reset issue is an old one and Uniden has ended the repair campaign and the other threads are closed. My current issue seems to be a little different.

    BC125AT: Battery Level effecting Receiving?

    (My model is the European BC125AT, the UBC125XLT) Does battery level effect the range that my scanner is receiving, or am I going crazy? I notice that (2.85V being fully charged) when my scanner reaches ~2.4V and lower, I start to get lower receiving range, less talking, etc. Is that...

    Thin/Compact battery for the XTS2500

    Can anyone suggest a good capacity lithium-ion battery for the XTS2500? I purchased an XTS 2500 because it was more compact than my XTS5000. However when looking at the photos of the XTS2500 the battery looks to add a fair amount of bulk to the radio. Can anyone suggest a thin quality battery...

    I've searched and searched, but can't find the answer I'm looking for. I'm going to wire my quad band mobile ham in my 2016 Malibu Limited 1LT (which has an auxiliary battery in the trunk to facilitate restarts when the auto-stop engages).
