Horrible performance and interference ?? Do tell ...
Bought the SDS 100 and 200.
All I did was fight the scanner, the SDS200. I Was changing the filters non-stop. Just when I thought I found a filter that worked best, nope... back to switching filters.
Was advised to get an outdoor antenna. Bought a 800 mhz Vertical antenna from DPD Productions and LMR400 coax, as advised, and mast. Antenna was picking up very very well and from a far distance. Was impressed. But... still switching filters non stop.
What I did find was the site I'm having trouble with receiving, I would have to have the mast and antenna at 53 feet. That's not happening as I don't have a way to do that. This height was determined from another RR user using his rf mapping. I should mention, I have a mesa in the way, and it was determined I'm getting signal through refraction.
Anyways, after all the testing things, trying things, etc.. I had numerous RR users tell me it sounds like I'm dealing with interference from something or somethings.. and at this point I was tired of switching filters.
Now, here's the catch...
My SDS100 is hanging on a wall in a bedroom to a radio clip, with a Remtronix 820S antenna. RSSI reads around -105 and I have the filters for my 2 sites set. I never have any reception issues, even hanging in the absolute worst area you could ever think of having a scanner located.
I purchased a Remtronix 830b for the SDS200. Put it back on and abandoned the outdoor antenna. I also found what I considered to be the absolute worst place to put the scanner. To my surprise, I haven't switched the filters, RSSI -100 to -104 and runs without an issue now.
At this point I have 350 dollars worth of antenna outdoors doing nothing. I am now at the point that I want to just sell the SDS200 as I think Uniden has screwed everyone on these models.
I've had at least 15 people tell me to sell the sds series scanners and get the 536hp as it handles interference MUCH better.
So, here I am... considering it.
I've also had a boat load of people private message and think it's absolutely INSANE a remtronix antenna would work better indoors than an outdoor antenna setup. I AGREE. It makes zero sense, but the Remtronix antennas beat the outdoor antenna setup, hands down, with no issues. I think if I had the 536hp and it was hooked up to the outdoor antenna I wouldn't have the issues. I belive the issues all fall with the horrible front end issues with the SDS series.
Anyhow, that's where I'm at with it all. I'm just debating if the filters of the SDS series would be better keeping in my horrible signal area and situation, versus the 536hp as I'm not familiar with it.
