SDS100/SDS200: SDS100 Scanning Issues

[blades561]

Hi Everyone

I recently bought the SDS100. Bought my County preprogrammed. Used Sentinel to create specific Favorite Lists with just the specific frequencies in my town. Perfect.

I have 2 issues, but the first is the main one.

Somehow when the scanner is scanning and worked, yesterday it stopped picking up what was working the day before. once in awhile like hours between something comes across. So I used my scanner radio app on my phone app a call comes across or the daily tone tests and not on the scanner. Always did until yesterday. If i stop the scan on the specific channel frequency it works. All the channels are in. I even went back and created a new Favorites list from scratch on sentinel and downloaded. Still doesnt work. Is the scanner broken or did I do something somewhere. I did try and run a conventional scan of my area but stopped after a few minutes and deleted the scan. Other than that I cant figure out what I could have done.

Thanks and I'm new with digital scanning as u can probably tell. I thought I had been doing real well until this. I'm stumped and dont want to send it back. Or if anyone knows anyone I can call to help.

Thanks Again
Pete

Oh fyi I just parked it on 1 frequency (Hold) at a time in the favorites list and it works. Not scanning but looks like it is. Im baffled.

The most common issue for not hearing what was expected is that the correct service types are not enabled. When your scanner was first shipped, and/or when Sentinel is first installed, only the Dispatch Public Safety service types are enabled. (Law Dispatch, Fire Dispatch, EMS Dispatch, and Multi-Dispatch). You also need to enable the Tac & Talk service types- Law Talk, Fire Tac, EMS Tac, etc. If you don't have those types enabled, then the scanner will not stop on them in normal scanning.

Also, make sure that your correct location, and desired range, are set. If you are using Location Control and the main database, departments and sites that are not in range, based on the settings you have entered, will not be scanned. Also, when creating a Favorites list manually, if you plan to use location control, then you must also include the location information for departments and sites on your list. During manual entry, the "location" would initially be 'blank', zero degrees for both latitude & longitude. That "location" is in the Atlantic Ocean, off the west coast of Africa. However, if you create a list by appending from the main database, the locations are carried over to your list along with the other system data.

For more details on how location is used in your scanner, see this:
How it Works: Location, Location, Location

Also, take a second look at your Favorites list, and ensure that a system, site, or department was not accidentally set as "Avoid".

Im baffled.

I'm down the road in the Cromwell area.

What are you trying to monitor?

 

[blades561]

I'm down the road in the Cromwell area.

What are you trying to monitor?

Howdy neighbor. Just rocky hill police, fire, and emergency.

It was all working for the 2 months I've had the scanner. I was thinking that my police channels weren't catching everything so I was messing around on Thursday. I realized yesterday morning that the scanner was scanning but not catching anything. If I hold on a channel like Fire Dispatch it works. Set back to scan the favorites list. Nothing works. I always heard the fire tone checks but not as of Thursday night.

The issue is that it worked from Jan until this past Thursday night. All of a sudden nothing. Every once in a while a piece of something comes across.

When I was programming manually I was meaning I created favorites list to just contain the ones I wanted to listen to. All was good for 2 months. I believe my police frequencies weren't catching everything so I was messing around trying a discovery bit stopped it and deleted. That was Thursday and I realized the evening I wasn't getting anything. The display looks absolutely normal as if it's scanning but finds nothing. I must have done something. It's usually operator error. Thanks

In your earlier post, you indicated that while the scanner was not stopping on active channels, you would hear transmissions if you manually stopped on a specific channel. Normally, this is an indication of some sort issue regarding settings, such as service types, location based errors, quick keys not enabled, and other issues that are not caused by a defective unit.

Now, you are indicating that you are hearing nothing. Do you still hear anything if you manually tune to a channel or talkgroup? Or does that no longer give any reception? Can you hear your local weather radio station? For a frequency (not a talkgroup), that you know is transmitting (based, perhaps, on your scanner app on your phone), try this:
Press the Channel soft key to pause scanning.
With the channel paused. enter a frequency that you know is currently active. Do not press the Enter key after inputting the frequency. Instead, press the Channel key again. Do you hear anything doing that?

If you do not, and you know that the channel is active (if in doubt, use your weather station's frequency, since those are always on), then it may be a hardware issue, possibly the much kicked around "cold solder joint". See this long thread for greater detail.

SDS100/SDS200: - Cold Solder Joint

As I've mentioned elsewhere, I sent my SDS100 in for the cold solder joint issue, and after about a month away from home, it came back working again. Until today. The A/C in my house is broken, and ambient has been 85F or so the last couple days, and so the SDS100 has been running warmer than...

Looking at the thread, especially post #6, it appears to me that there may be an issue with the way discovery mode was stopped and deleted. Hopefully, someone more knowledgeable than me about discovery can comment on whether stopping discovery can disrupt a return to normal scanning.

I've had discovery unintentionally get disconnected, and so far, the only thing that has impacted is occasionally the session itself, not saved correctly or getting corrupted. Have not seen any effect in regards to returning to normal scanning.

Ok here's the file. Hopefully its right. But an interesting development. After shutting it off and turning back on this morning its now picking broadcasts up. Its not that hadn't tried rebooting it or shutting off overnight. As I am typing this it now seems to be working. I have gotten a few broadcasts already from multiple frequencies. The only other thing I did last night while working with someone on reddit, I did switch the Global Auto Filter to "Auto" from Normal. I have never touched that filter until then. Maybe it got switched by the discovery I tried to do. I'm too new to have an idea.

Thank you for helping

Looking at your file, I don't see anything that stands out as "wrong". I see that your city, Rocky Hill, has a single talkgroup on the state's system, CLMRN. but you do not have that programmed.

Since, at present, you only have a handful of conventional channels programmed, the "Auto" setting may not affect you very much. But using that does slow down your scanning, as the radio tries all the various filters to see which is best, That could result in a delay before you actually hear anything. Unfortunately, the scanner does not remember what Auto setting worked best, so every time it lands on that Department, it again tries all the filter options. That's one of the requests made to the new Uniden rep, 'Joe Bearcat', to see of the scanner can remember that setting, and use it the next time the system or site comes up. Or, at least display which one it chose, so that you can mirror that in your programming.

As you only have that single department programmed in your Favorites list, the scanner may well leave whatever filter setting it chose in place, since it's staying on that single department, not moving to different ones and going through the evaluation repeatedly on each one. But if you add additional departments and/or systems, I suspect that you'd notice a degradation in scanning speed.

If, as noted, you started getting reception after setting the Filter to Auto (from Global, which would be 'Normal' unless you chose something else in your Sentinel profile), you may have some nearby source of interference that the "Normal" setting does not abate. Unfortunately, finding the correct filter setting to use (other than relying on the Auto setting, which slows scanning) means doing it manually. Try changing the filter (from Auto) to the various choices, letting it scan using that long enough (at least a few minutes each time) to see if that is better or worse. Among your choices are Normal, Invert, Wide Invert, Narrow Invert, Wide Auto, or Off. While most of the systems I monitor do well just with the default of "Normal", there are a few that a different choice makes a noticeable improvement.

If i stop the scan on the specific channel frequency it works.

When you stop scan it will not use the Service Type and it will not use the Broadcast Screen. In Profile check the tab for Broadcast Screen and untick all boxes so that no filter is in use. Check also that the Service types are enabled.

SDS100 are not the best scanner to monitor 400MHz frequencies and might need a lot of fiddling with the filter settings and IFX.

[jonwienke]

Wrong. The SDS is somewhat more susceptible to adjacent-channel interference than the 436, but that applies equally regardless of band. In the absence of a strong interference signal, the SDS100 and 436 perform similarly on all bands.

A couple clarifications. My favorites list is right from the info on here radioreference. The whole reason my issues seemed to start because I believe there are more frequencies for the RH Police Operations etc. Ive been told be Uniden that the scanner should automatically pick up the backround frequencies but it doesnt seem to. So I've been trying to find out the issue. Is there any other places I can find more info on my town as well as others?? I switched back to normal to see if it works. Global is still missing broadcasts.

Thanks so much for your help, knowledge, and patience.

In the absence of a strong interference signal, the SDS100 and 436 perform similarly on all bands.

My 436 and SDS100 do not behave the same and I mostly do analog and no subtone scanning and can clearly hear the difference. The internal mixing products and birdies seems to have more impact the lower the frequency. In the 450MHz band where I have 15-20 frequencies within 2MHz at a -80dBm to -110dBm level where it's difficult to not run into problems with intermodulation and mixing products in the SDS100 regardless of filter and IFX settings, but the 436 are solid as a rock. There's no signal stronger than -70dBm in my whole 320-510MHz band.

SDS100 test

In the 800Mhz band with a search with squelch set at 2 the interferencies doesn't seems to affect the search rate at all. In UHF it starts to hesitate at certain frequencencies and at VHF it really starts to slow down search at about 50% of the time. The interferencies are of such high distorsion and squeling high pitch noises that the squelch doesn't open but only stops briefly and then continues to search.

The audio interference where exactly the same in all bands VHF,UHF and 800Mhz, so it's probably something that happens in the receiver after the first mixer in the 1:st IF. If you only scan digital or mostly use 800Mhz band you'll probably never be aware of the problems with the receiver. These interferencies will blend with all signals it recieves and create mixing products that spread all over the frequency band.

/Ubbe

 

[jonwienke]

I test the SDS100 and 436 against each other on airband regularly, VHF and UHF. When connected to a common antenna, they very rarely do anything but play identical traffic when monitoring the same frequencies. I test on airband because it's AM, and cold solder RX oddities and artifacts don't get masked by FM/digital capture effects.

The person that told you that "the scanner should automatically pick up the background frequencies" is not correct. What you see in the RadioReference database is based on information submitted by members of RR. If there are other frequencies, that no one has submitted, these will not show in the database, and so the scanner would not stop on them automatically. You might run across them if running a search, but if you wanted them to be scanned as part of a Favorites list, you would need to either program them yourself, or submit them to the database, so that once updated, your scanner will access them based on that.

Is there any other places I can find more info on my town as well as others??

You can do a search to see what else your town is licensed for.
Go to the Hartford page in the database.
Click on the tab marked "FCC Licenses".
Enter "Rocky" in the Entity Name field.

Click on retrieve.
That gets you to a list of licensees that have 'Rocky' in their name.

Click on one of them that has 'Rocky Hill' and 'Town' in the name,
That will get you a page with any licenses for your town.

RR Database Home

The most complete database of radio communications data

www.radioreference.com

I skimmed through the licenses, and it appears that almost all of the Uhf frequencies that are licensed appear in the listing for Rocky Hill under the Hartford County page. Of the two 'base station' frequencies that are not shown, one is labeled (on the license) for public works, the other for a school. There are a number of licenses listed in either Vhf-low, or Vhf-high, that are not on the page, but those might no longer be in use. You could program them and see if anything comes up. I'd bet that the Vhf-low frequencies are obsolete, and have not been used in quite some time. That may be the case with the Vhf-high frequencies as well. Since all of the listed channels in the database are Uhf, maybe the Uhf frequencies superseded the Vhf-high ones when new radios were purchased.

I switched back to normal to see if it works. Global is still missing broadcasts.

That leads me to believe that something is causing interference for you. Could be an FM or television broadcast tower, or maybe a business trunked system.

Thanks so much for your help, knowledge, and patience.

Your welcome.

Try the attached file. Extract the 'new to fix.hpe' file from the zipped file, and import it into Sentinel, then load on your scanner as a test.

I set the filter on this file, for your "Hartford" Department, to "Wide Invert". That's the setting that I see mentioned most often as one that helps. I have one of the Uhf departments in my area set to that as well. Leave your "Global" filter for the scanner at "Normal".

I added a department "Still used" for the vhf frequencies that are licensed for Rocky Hill, but not showing in the database. I entered only the ones listed as base frequencies.

I also added the statewide system, with just the Hartford site, and the talkgroup listed for Rocky Hill. If you find that they are using that, then possibly there are other TGIDs for Rocky that are not currently listed.

 

[jonwienke]

The scanner will pick up voice channel frequencies that aren't listed in the database if the site control channel is listed. But if a site's control channel isn't listed, then the scanner won't.
