I’m am very thankful for what u told me and ironically the frequency I gave me is not ne of the frequency the scanner pick up manually...so is there anyway I can listen to the talk groups?? Basically is there anyway I can hear the pd from this pro 74 ���� please help tomorrow is Xmas and I’ll have to give it to my husband I just want to surprise him!!
Thanks in advance I appreciate your help u really are a angel from heaven merry Christmas and happy new year...
As Troy and I said, most Frederick County public safety organizations operate on a system that requires a scanner capable of decoding P25 digital signalling, which unfortunately your PRO-74 cannot do. It's confusing for those new to scanning because not only does the scanner need to be able to receive specific frequencies, it also needs to be able track their trunking radio system, and be able to decode the P25 waveform.
A local company may be able to assist you on which scanner to purchase:

I would make sure to buy a scanner that is capable of decoding the latest version of P25 signaling know as "Phase 2," which is backwards compatible with the earlier version of P25 signaling know as "Phase 1." Frederick County is currently a Phase 1 system, but as part of the National Capital Region, they may be transitioning to a Phase 2 system in the future. The other determining factor is the state of Maryland is building a Phase 2 system currently, and it's operational in Frederick County now, and in Western Maryland counties in 2018.
That said, your scanner is capable of receiving the dispatch side of the Maryland State Police Frederick barracks *if* they are still using their VHF (low) frequency: 39.400 It's *possible* that you may hear field units if they are very close to you when they transmit. However, they will be transitioning to the state's P25 system in the near future. The state police also have there own talkgroup on the Frederick County system (which again your PRO-74 cannot receive.)
Hope this helps.
