Anybody know the frequencies for the fbi office in Dothan al

Don't count on hearing much of anything. It seems agents prefer cell phones.

Never heard squat from the Mobile office.

Anybody know the frequencies for the fbi office in Dothan al

Alabama is broken up with two different Field Offices.
Mobile and Birmingham - each has under them multiple Resident Agencies (RA) also known as Satellite Offices

Donathan covers the following Counties

• Dothan: Barbour, Coffee, Covington, Dale, Geneva, Henry, and Houston counties

Generally FO Radios are broken down into Zones in the Radios where Zone A (Admin) is assigned to the FO and is likely 4-8 channels/Repeaters then B/C/E/F/G etc are broken down by the RA (Notice D was skipped as that is a Nationwide assignment Zone)
Depending on your area/geographic size the Zone can be made up of 2-10+ Repeaters - generally (Except Zone A and D) linked, so what is heard when they are on that Zone is heard across your entire Zone
Since you are asking, I will assume you found Nothing in the RRDB or very limited

AL Federal Agencies (Alabama) Scanner Frequencies and Radio Frequency Reference

Scanner Frequencies and Radio Frequency Reference for AL Federal Agencies (Alabama)

www.radioreference.com

your best option is to SEARCH 162-174 at 12.5 khz channel spacings and see what you find.
Only YOU are going to know/learn what you can hear from your QTH

Keep in mind Federal Surv Activity is not like listening to your local PD/FD/EMS - you might find Nothing for weeks/months, then a major flurry of activity then nothing for a long time or even then Off Hours, Weekends, Holidays - you never know unless you try.

Now, despite the tourists (those not living in AL, myself include) indicating Cellphones or ENC vs CLR - only you are going to know yourself

Now - don't be quick on the draw to post immediately what you hear/find, if found in the CLEAR, take notes
Callsigns. Freq/NAC, channel names and best of all address info - log (write it up) then share it weeks later once it cools down

Discovering my local RA channel plan has taken over 10+ years of notes, listening, sharing with others and luckily some DF'n of the sites to narrow down where the repeaters might be, as one of my RA's covers the entire Southern portion of the State with 10+ Repeaters covering from just south of Boston to also Cape Code and the two Island.

What ecps92 is saying is, don't count on hearing much of anything.

From someone who worked with FBI, ATF, et. al, for years, they prefer cell phones. In my city of about 200K, both FBI and ATF were also issued radios for the city's system and they didn't use those either.

Don't put words in my mouth Not even CLOSE to that

Don't count on everythin being 100% encrypted all the time. Recently there was a big multi-agency drug action and felony warrant roundup in my area. A lot of out of town agencies brought in. Along with the local repeater two "new" repeaters (nationwide allocations) that I never heard anything on before came to life. There were several radios in the clear for some reason.

B I haven't listened to 162 - 174 in years, but even back then everything was encrypted. There is a transmitter
close to me with so much power I almost have to disconnect my antenna to keep it from overloading my receiver. 167.7625
P25 NAC 330. No traffic monitored. It sends out a digital station id every 2 min. Some freqs I saw this morning, no
traffic.
169.9125 P25 NAC100
171.1875
171.3250 P25 NAC200 encrypted audio ?
172.0625 P25 NAC100
167.1725 ? Strong
167.7625 P25 NAC330 2 min dig station id
Most of these are talked about in RR, different agencies, use at your own risk.

as Freqs get re-used by multiple agencies across the different Regions, where did you monitor these from ?
it helps to know, to formulate a correct reply

 

[ChrisP]

I would just add that I had this info for the Dothan RA from years ago, but might be worth a listen:
167.6625
167.5625
167.5375
163.9375
163.8625

Southeast Alabama, since B Mendez is from Enterprise and I responded to his request for freqs in the Dothan area, go figure.

Thanks for the Reply of "AL" - it helps in formulating replies with valid information
BTW - with the Hurricane how is the VHF Band ? Open at the time or Monitoring ?

169.9125 $100 - ICE from the Tampa/Fort Myers wide-area Net
171.1875 - too many possibilities in the SE US without the NAC
171.3250 $200 - BP in FL/MS - NOLA Sector EAST Net either the Pensacola or Gulfport Repeater
172.0625 $100 - ICE from the Pensacola wide-area Net
167.1725 - invalid frequency
167.7625 $330 - DOJ Wide Area Net - shared by FBI/USM - never nailed down where, but likely in Southern AL

Never had a report of $167 in use for AL, so all logic points towards the DOJ Nets with $330
and the general RID's for AL FBI units should begin with
a. 306xxxx Birmingham
b. 330xxxx Mobile - only just realized the RID's match the NAC

No skip for a couple of days now, not a 24/7 monitor. Enjoy the hunt, gonna sit on 162- 174 for a while and
see what I can see, but that 1 powerful station (167.7625) overloads the spectrum. Using usb SDR's. Later....

Question, anyway to pin down a transmitter site using FCC, property records etc?

FEDERAL Agencies - rent, lease, have their own sites, so other than DF'n or CLR traffic to indicate which site/repeater they are using... years or monitoring.

Altho side note, here in New England we had a rough idea of where a repeater was (narrowed down to 4-5 neighboring towns - all with Rental Towers) and low-behold what comes across the local Power channel during a major snow storm.... can you get over to xyz street that Big tower had an FBI Radio there and the generators are about to run out of fuel in the next 3 hrs...see what you can do to restore the main.

FYI saw 171.3875 NAC:167 with a RID of 8802305 with a lat long attached(?).
Is it ok to put the lat long here? My antenna is pointed south from Dothan but isn't
that narrow (log periodic). Lots of signals in the 162-174 range only a few are left after
the morning skip ends tho. The one above was logged at 10:36 CST and fairly strong.

Looked at my antenna rotator, not south, moved it to the east. Tower located at the
Jefferson County Florida Sheriff's office (Lat Long). Must be powerful to make it to Dothan with
a strong signal. The lat long was the radio's alias, go figure.

Mil

this is the last post I'll make here, go to the Federal section I guess.

880xxxx likely a USM Radio on the Pan Handle Net - and has been seen on being from FLA in the past
now the Lat/Lon (first time seeing/hearing those on FBI - Great Find)

Keep it here(IMHO), since it was about AL FBI Offices.

I doubt the Repeater is sending the Lat/Lon it is likely a Mobile or Portable with GPS enabled.
That said, it could be on Any of the multiple Pan-Handle Nets as they (generally) are all linked, so now the game is
to nail down where this actual repeater maybe, while also not knowing which repeater the unit is actually using.

Note - most Wide-Area NETs use a common input, but multiple different outputs.
Same applies to those with Vote-Scan

What is a USM Radio? DSDPlus log excerpt, someone may understand it, huh?
