I really want to like my SDS100, but have found a lot issues since using it for a Month now. My 436 outperforms it in almost every way. Reception is just bad. Either missing transmissions or over modulated P25 Phase 1. The internal Speaker is terrible. Just tinny sounding. I have to use earbuds connected to the SDS100 to understand what is being received clearly. The Radio just gets Hot. Which is probably why the battery life stinks. I’m sure even with the larger battery coming, it still won’t match the 436. And it takes a really long time to recharge. The display is hard to read on bright days outside. No matter the Display Settings, just is unreadable. Other than that it’s a great radio.
I looked back on your previous threads (Well not just you back many constant complainers). From Day 1, you haven't liked the speaker (Working great for me, not using ear buds just old fashioned ears). Missing transmissions or over-modulated Phase 1 Transmissions (Must be ear bud related because I'm running a Phase 1 system and have missed really short replies so reverted back to original firmware, until a fix is found but working great otherwise). Radio getting hot (Yes, it get's warm but not hot. What kind of charger are you using?). You have seemed to be dissatisfied from the beginning, but instead of returning it, you kept it. My display is white background and black text and Simple Trunk mode. When I'm outside I wear sunglasses and can see it perfectly. Unless you have a problem with your eyesight...well I'll leave it here.
You mention transmissions dropping out. Their have been 3 firmware upgrades that have addressed issues. Did you submit any debug files or learn how to set that up? I didn't either but I have learned, sent them through and some issues have been addressed as a direct result. You should try this route instead of complaining about a product you're unhappy with and didn't return it within the return window. Their are many out here who have loved to try it out, who are in a simulcast hell (That's me), and have been satisfied with our choices.
I think their must be over 100 threads on this scanner...it works and works very well. Many of us, including myself, are working with UPMan to tweak this product by submitting debug files instead of the constant whining and complaining about "I don't like this/this doesn't work/I can't hear". Is it possible you damaged the scanner trying out one of your off-market non-approved antennas and cracked the housing? Is it possible you downloaded from the database and the NAC codes/frequencies were not correct? Seeing more of that lately, but it's difficult to follow all the threads.
It appears you have an offer...sell the damn thing and save us all the *****in!
