Probably, but... And there's always a but... Depends on your use of a high quality electrical surge protector and if you use an outdoor antenna, how well you have it and the coax lightning protected.
What does it mean when i see cap+ at the top of my sds100 i know it's dmr but is it a trunking one i tried searching for it and the freqs ain't in the database but it's 461.6500 i have always seen DMR at the top but never CAP+ until now if i programmed that into sentinel would i choose dmr one freqs or motoTRBO ?

As it's only one frequency you can program it as OFT and monitor both slots. If it turns out to have a second frequency then you will have to program those as MotoTrbo and enter their correct LCN numbers.
You should probably verify that frequency using another receiver so that it isn't a false mirror frequency in the SDS100.

what is a false mirror freqs?
so does that need to be put in sentinel as just dmr one frequency or does it matter which way i put it in.

If a unit cannot be fixed, often a replacement is offered for a price. The keys may (or may not) be transferable since the old unit can be claimed as no longer in use.

It's oscillator signals, that shouldn't exists, in the scanner that works as a mixer and creates other frequencies where you can hear a transmission.
I made a test on my SDS100E to see how bad it was, it's always worse in SDR receivers than in conventional receivers like BCD536HP.
I generated a strong signal from a RF signal generator and tuned around in the frequency band to see where those mirrors appears, and it's pretty bad in SDS100. In digital mode you don't hear those mirrors as you only listen to the decoded analog audio from the digital signal, but will compromise reception just as much as in analog mode.

They use each slot as a separate conventional channel, so not trunked. If you only want to hear FD Dispatch then monitor only slot 1 of 155.970 but if you also want to hear FD Tactical you monitor both slots.
Even if a system are trunked you can enter their channels to monitor but it will not follow a call if it happens to jump between channels during a conversation. But you then don't need any LCN programming to be done as you will if programmed as MotoTrbo. OFT are good for unknown trunked systems until you figure them out.

All that info is in the link I provided to you previously here. There is even information in there on determining the LCN's on DSD versus Uniden for DMR Tier 3 systems.
Ok i don't know why this is happening but whenever my sds100 stops on a dmr freqs it hangs there with no audio sometimes there is audio sometimes there is no audio and it just hangs . it doesn't do this on any other freqs such as nxdn or p25
Here is a video showing how the sds100 while scanner will stop on a frequency and hang there for a long time with no audio, It always does it on the dickenson dmr site and i just noticed it's doing it on a p25 site as well. is this fixable it really slows the scanning down.

The time it stops on trunked systems is to check for activity. It cannot be sped up.
Yeah i know that but this is conventional , what i mean is i have it programmed in as conventional . also it's not a control channel the dickenson freqs it's hanging on is not a control channel all the audio happens on that one frequency. and this is not how a trunked system is when i'm scanning with stars enabled it doesn't just hang there for 30 seconds before it moves on . could i have it programmed it in wrong. i read on another post that it's a tier 3 system and i have it programmed as conventional. the freqs is 154.8600 153.1250 and 155.7000 these all show NXDN but dsdplus is telling me they are DMR and my sds100 also tells me they are DMR
I tried using IFX but that didn't help either
