The sleep timer is like what, 20 years overdue? I had one on my Icom R2 and it was the best and wanted feature in a very long time. I loved that radio as nobody had only 2AA back then, and killed the BS theory about portables having poor audio quality and crappy volume due to their small size. Nope, mostly Uniden and sometimes GRE used crappy stuff. I really hated radios like the Pro 51 and Pro 94, 235, 245 XLT, and many others. If the R2 had good volume and sound, so should every flagship model by Uniden etc. Uniden has come a long way as I use to hate them witn a passion for all the junk they released with the telephone battery packs and/or expensive packs that don't last like the 2500XLT. I actually liked the 2500XLT other than that which was unusual at the time. Even the 9000XLT had crappy audio and less than par squelch tail. If Uniden picks up the audio and speaker quality, then they'd be great. After spending all that money on the SDS 100 and 200, I better get decent audio or I'm going to rant like I haven't since the 780XLT came out sounding like crap. We're back to the proprietary battery packs again, but that display is too awesome to run on 4AA.
