As @rcool101 alluded to above, the rem810 is probably not making good contact with center post on SDS100. If you are scanning 700-900 MHz and want a portable antenna on an SDS100 I’d recommend rem820s.

There was a REM-800S for the BCD436HP etc. That was a large diameter adapter. I am pretty sure that the REM-810S has a reduced diameter to fit the SDS100. The REM-820 has the O-ring for water resistance.

REMTRONIX REM-810S 700/800/900 MHz SMA Antenna For Uniden SDS100 scanner NEW! | eBay
FULLY Compatible with Uniden SDS100. This antenna was made specifically for the Uniden SDS100 scanner. It will not bottom out like the REM-800s does. It seats fully into the antenna lip. SMA Connector(Standard SMA).

That is what my purchased two years ago, my mistake.
Ok, so maybe a little late to suggest this, but it if you take antenna off often I would recoemmend an sma/bnc adapter and bnc antenna. Leave the adapter in place and a simple 1/4 twist to take off bnc antenna.

With ID Scan, you receive only the talkgroups you programmed. With ID Search, you receive every talkgroup on the system whether programmed or not. It doesn't affect how well you receive the system.

As soon as you see signal levels of -75 -70 and even stronger at -60dBm you could try to add the attenuator to those frequencies to help the scanner cope with those strong signals and any eventual interferencies will also be attenuated.
If you see the signal level drop more than 20dB, it should go from -75 to -95 when switching on the attenuator, it would be a sign of that you have interferencies that the scanner reacts to and looses performance.
If you use color code search and ID search it will help the scanner to receive the signal as it will ignore any false decoding that it otherwise would mute and begin to scan.

I've had this radio a year, and it seems no matter what system I input locally, when Attenuator is applied the RSSI goes blank, DATA and D-ERROR dissappear, and NOISE goes through the roof.
What is color code search and how do you do it?
Currently, as I mentioned in another post I have a P25 system, an EDAC, and an analog. The P25 is the culprit as I have always discussed on this forum. I have reformatted my SD Card, re-programmed everything, and only customized Global Auto Filter to Wide Normal, Wide-Invert, or Off in this particular post, so currently I am at Wide-Normal with Squelch on 3.
The P-25 works perfectly fine with RSSI between -45 and -50, NOISE in the hundredths (200-500) and D-ERROR at 0 if I set squelch to 1 and Filter off. In the past, I questioned if it was the correct frequencies because if I go to a particular location, I have picked up two talk-groups I don't even know what system they are apart of, it appears some type of ambulance service but it is not under my local frequencies.
The EDAC works fine since I took this radio out of the box. However, the RSSI is always in the -70's (with a little over half bar on the bar graph when dormant, when there is conversation its always -60 though) and D-ERROR does not show, but it has never flickered, garbled, or anything. Now if I move the radio into my back room where the P25 works perfect then this system has gone down to -45 RSSI as well and D-ERROR becomes 0.
With Analog, when dormant NOISE is through the roof and RSSI goes blank and only when there is conversation then it goes into the hundredths, the RSSI is always in the -90's.
The EDAC and Analog comments are no matter with or without changing Squelch.
Now for all three systems, I assume and attributed because I am still a newbie with this, that because of the internal radio recycle I have witnessed the RSSI jump for like a milisecond (-45 will become -95 and go right back and -95 would become -110).
For the most of the past time, I have left Squelch at 1 and Filter off, so I wouldn't have issues with any of them and being life gets in the way =). Hope this is helpful.
PS- The Remtronix 820S will be here on Saturday.

Could you do a debug log that we could look at? It would show that you are not suffering from any bad solder joint problem that could cause a lot of headache.
Hold down the Avoid button and power on the scanner and keep holding the Avoid button until the favorite lists starts to load.
Then go to the scanner menu and choose Setting and you should find a "Set Debug Log Mode" menu.
Go in there and select "SD Card" and then exit out to normal scan mode.
Let it scan for a minute or two and then connect the USB cable to scanner and PC and select Mass Storage Mode.
With the Windows Explorer program that handles files, (or just hold down the Windows button and E on the PC keyboard and click on the SD card) go into the SD card drive and down into the BCDx36HP folder and into the Debug folder.
Copy the files there and zip, 7zip or RAR them to make them smaller and attach to your message here.

Would Monday be better, when there is more activity? I did this before with you too and there wasn't the joint issue at that point. Should I do this every so often, like a routine check-up?
This time, do you want me to log it during regular circumstances (squelch on 1, Filter off), with Squelch on 2/Normal Global Filter, or when its programmed as conventional? With my computer being in the office, it might not pick up as much as it does in the rear of my home.

Ah, yes, that was in the other thread. If you feel that nothing has changed then no need to do another log session. It doesn't matter if there's activity. As long as the scanner are scanning frequencies it will show if there are any miscommunications going thru that connector. There wasn't any in your previous log so probably just some strong transmitter making your signal strenght jump and perhaps even blocking your reception.
Remember that a SDS scanner has more than a 7Mhz wide spectrum where it senses transmitter signals and adjusts its gain in the receiver to adapt to the current RF situation and the filter, attenuation, and IFX settings that your are using.
