SDS100 200

[n0wla]

I have a 100 and 200 both programed identical. In side-by-side comparisons the 100 out receives the 200 by a lot. Anyone else ever experience this?

No.

Are they connected to the same antenna?? If not, get a multi-coupler & try again, or at last use two identical antennas & test in the same environment / location.

There are so many variables that that doesn't mean much. One radio can even affect a radio that may be near it. Filter settings, antenna locations, etc., make a difference.

Certainly can't judge radio rx by programming alone. What are you using for an antenna on each? Have you connected the same antenna independently to one then the other? Is the squelch set identically on both? (not impacted by programming) You've ensured the same service types are enabled on both?

Stock antennas on both, locked on same FL, SQL on 2, 100 chatters on while 200 scans with an occasional hit.
Switched 200 to outside discone with same results.

And my last question?

I will reiterate a previous poster.
Unless the radios are connected to the same antenna (via a multi-coupler), any reception comparison is invalid.
Just a few inches difference in the radio's position - and certainly the antenna's different gain, etc. can and does make a difference.

Are the radios really side by side or is there some separation. Something near one scanner could cause a wee bit of de-sense.

squelch ?

Have you considered what part simulcast may play here? First, if you can determine the SDS100 is receiving simulcast agencies when the SDS200 is not, but all conventional analogue frequencies are not affected, you may be experiencing simulcast distortion. While I have not seen this happening between these two SDR units (as that’s what these two are designed to combat against), it’s important any comparison be done with the same antenna as previously mentioned. I am assuming all programming is identical in each radio and both radios are placed in exactly the same spot, one at a time, with some distance between both. Put the SDS200 in the exact same spot as the SDS100, removing the SDS100, turning it off and parking it away from the SDS200. A quick way to determine this is to take the SDR card from the “good” SDS100 and instal it in the SDS200.

As a long time owner of both SDS 100 & SDS 200's, yes it is possible, the reception could be different. My SDS 200's all run off an outdoor antenna and on certain systems, I have to apply the attenuator where the SDS 100 doesn't need attenuation. Since I self-program using Sentinel, I copy these systems, rename them (Illinois State Police SDS100 for example) and edit the profile so only that favorite list is added the the proper scanner(s). As it's been said for many years here, these scanners need to be experimented with and once you find the optimal settings, you save them and read them back to Sentinel to save it.

Can you post a short video or link to a video of them both in with the display in detailed mode?

 

[tglendye]

I’m curious which system and what type it is?
