In your screenshot, you are tuned to 154.5475 (not 154.55). From FCC Frequency Search, this frequency and 152.8775 are licensed to FCC Callsign: WQVP567 (Powell Valley Electric Coop). It is possible that this is what you are receiving.

The VA.csv file used in FMP/DSD+ has this as:
154.5475, 0, "Blooston, Mordkofsky, Dickens, Duffy & P", "9635 Radio Rd/Norton/WISE", 36.8894, -82.6205, "7K60FXE", "11K2F3E" ; VA​
152.8775, 0, "Blooston, Mordkofsky, Dickens, Duffy & P", "9635 Radio Rd/Norton/WISE", 36.8894, -82.6205, "7K60FXE", "11K2F3E" ; VA​

However, as you note, it does not look like these frequencies are included in the database.

Your dongle appears to be off-frequency. I believe this is causing you some confusion. You may want to refer to this post for tips on making a ppm adjustment (if you have not already done so).

That freqs is showing DMR BS DCC:6 for me but no freqs that i can see in that list says DMR. any ideas why? also that freq is strong but has no traffic at all on it , it only shows this

As previously mentioned, it does not look like these frequencies (154.5475, 152.8775) are included in the RR database in your area. No one has confirmed the usage of these frequencies and submitted them to the database. The link I provided is from an FCC License Search - as a possible usage of the frequencies..

You will notice that the emission designators listed for the license includes:
7K60FXE : This is 2-slot DMR (Motorola MOTOTRBO) TDMA voice.​
So, this is licensed for DMR.

It may take some detective work to confirm the usage of these frequencies. I'd start by listening / logging traffic during the day (during business hours). So far, you have only seen LRRP location data transmitted, but apparently no voice transmissions.

The license shows the Licensee as: Powell Valley Electric Coop. (The contact is listed as: Blooston, Mordkofsky, Dickens, Duffy & P). The location is 9635 Radio Rd; Norton, VA WISE County (about 39 miles from you)

You may have better luck asking about these frequencies in the Virginia forum (virginia-radio-discussion-forum.20)

Again, you really need to understand what your seeing and how it works.

White Gps data being broadcast on that freq. Your not going to hear audio.

Red ppm still off. You cant figure out what freq your on unless its tuned properly.

Green noise floor still high.

Orange multiple users licensed for same freq. Does not mean they all use it. Does not mean any of them use it. Does not mean the listed emission is what's being used. Turn that off. Your relying on the settings in your fmp24 cfg that specify your location and a range to display. Your near a state border and using an LNA.

Take his advice. Research what you hear. Go to some of the gps locations showing on LRRP when they are near you. If you see power company trucks at each location, then you know who the user is. If you see school buses, then you know.

There are some possible clues contained in the LRRP information. Google Maps shows that one of the gps coordinates is at a SCTC (Scott County Telephone Cooperative) facility in Gate City, VA. There is a relationship between SCTC and Powell Valley Electrical Coop (PVEC). PVEC Fiber is a partnership between PVEC and Scott County Telephone to provide broadband access in the area.

Keep listening to see if you capture any voice traffic that helps to determine the usage of these frequencies. Likely candidates include PVEC, SCTC, and PVEC Fiber. (The detective work can be one of the fun parts of the hobby)

Can someone with more knowledge than me maybe help me with this, this is a problem that i have noticed for awhile now and i can't figure out what is going on i have tried searching it on google and i'm stumped I have all these frequencies popping up every where and they pop up really fast and disappear when i stop on them and catch them i hear a few words get spoken u can hear it in the first part of this.

I will keep listening and see. i will just program them into my scanner and keep an eye on the proscan recordings

Frequencies just don’t pop up on my scanners. You either have them programmed, or your are searching a range that includes them, or you have close call on, or using full database. Maybe something else that I am not thinking of at the moment.

Looks like you made unwanted changes to DSDPlus.


Just a reminder,

SDS100, Provoice, DMR, Menu, Questions.

That's the title of the thread. DSDPlus should be discussed in the appropriate forum.

Yea i saw that sorry here is the Video the freqs are just popping up all the time really fast like that and it's hard to know where to begin to figure it out.
Video mostly shows you hovering your mouse over different areas of the visible RF spectrum thus the "freqs just popping up". Looks like normal operation to me...unless I'm missing something

i'm talking about the freqs themeselves they are popping up like that and when i can catch one it says its IDAS and i can get a few words of traffic from time to time but i can't narrow it down to what is what

Have you used the frequency query search (one of the perks of your RR premium sub) to look up your findings to see if any are listed in the RRDB?

FCC search?


If this is the case have you searched surrounding state(s) you may be within range of?
yes i even added them all into the scanner and double checked to make sure they were all 450mhz freqs and scanned those but i'm not hearing anything . here is a freqs that i get a few words when the signal bleeps up 451.42500 i searched that freqs and added all the utilities i added all those and scanned them and don't get anything it's got me thinking it's a trunked system and thats why i'm not hearing it but i don't know

I believe you are playing whack-a-mole trying to chase the frequencies in dsd+. Once you catch a frequency, stay there. Don't try to tune to another frequency. Stay on one frequency until you are able to get a feel for what it is. Wait for more transmissions on that frequency - then wait some more. Write down your observations.

I am not sure you are tuned to the center frequency. I suggest that you enable the Zoom Spectrum Overlay in FMP. This is the green plot which is a zoomed in view of the frequency you are tuned to. (This is toggled using Z in FMP.) Use the up/down arrows to center the frequency in the shaded region.

yes i have i still can't find anything
What exactly have you searched?

One of the frequencies shown in your video is 451.925. An FCC Search (in VA) for 451.925 returns Pocohantas Gas LLC in Buchanan County.

Many of these frequencies appear to be used by utilities in the area - and are not included in the RR database.
