A recent posting by Customs and Border Protection (CBP) reports the capture of a group smuggling marijuana across the southern Arizona border with Mexico. The Yuma Sector was involved in the arrest:
https://www.cbp.gov/newsroom/local-media-release/border-patrol-agents-arrest-15-connection-possible-smuggling-network
Photos that accompanied this report on the CBP Twitter feed showed the radios and batteries that were seized during this arrest.
The CBP photo shows several models of Motorola TRBO digital radios, probably UHF. I'm wondering if they will do any forensic radio analysis and see what frequencies they were on.
The drug cartels in Mexico have long been known to use radios, and not just portables. A while back, there was a wide-area radio system with linked repeaters that was reportedly build by a company in Houston, Texas. It was operating in an unusual part of the UHF military air band and was fully encrypted, of course.
Which brings me to a recent discovery when I was in Arizona. I left my radio searching unattended while parked at a fairly high altitude near the Mexican border. I recorded a number of encrypted DMR hits on unusual UHF frequencies. I caught quite a bit of traffic on 403.2500, 403.3500 and 403.4500 MHz. All the communications I recorded were using the same talk group number (116), so this might be part of a trunked system. Is this really related to drug smugglers? Who knows, but an interesting catch none the less...

Fairchild Air Force Base, Washington
Fairchild Air Force
Base, located near Spokane, in eastern Washington, started out life as the
Spokane Army Air Depot back in 1940. Local business owners and citizens raised
the money in order to bring the base to Spokane. The base was renamed in 1951
in honor of General Muir S. Fairchild.
Fairchild was at
one time home to the 92nd Bomb Group, flying the B-29 Superfortress.
The base also supported the B-36 Peacemaker for a time in the early 1950’s. The
base became home to B-25 bombers in 1956 and KC-135 tankers in 1958. During the
Cold War, a ring of nine Atlas intercontinental ballistic missiles silos
surrounded Spokane and Fairchild Air Force Base. These were operational from
1961 through 1965, as part of the Air Force’s 567th Missile
Squadron. The bombers moved away in 1993, making aerial refueling the base’s
primary operational function.
In addition to the
tankers, Fairchild is home to the Air Force Survival School. The 336th
Training Group teaches SERE tactics, Survival - Evasion - Resistance - Escape. Some of the real-world
training takes place in the nearby Coleville National Forest.
The base itself is
served by a VHF P-25 digital trunked radio system. This system was a Motorola
system years ago (the last time I was at the base), but has since been upgraded
to a true, P-25 system. Base personnel that I spotted with radios seemed to be
using mostly Motorola APX radios. The system appears to be a single site with
no networking to anywhere else, but with the recent trend of military base
radio systems being networked with other bases, I would not be surprised if
that happened in the future here at Fairchild. Here are the specifics of the
base trunked system:

In addition to the
trunked system, there are a number of VHF and UHF conventional frequencies
allocated to the base. While on base for the 2017 Skyfest air show (more on
that later), I spotted a variety of antennas on hangers, buildings and small
towers located all over the base. I have confirmed a few of the UHF air band
frequencies, and have information that some of the VHF channels are being used
for the USAF Survival School training. Here is a compilation of my database of

2017 Solar Eclipse NASA Frequencies
-->
A rare natural phenomenon
that occurred on August 21st, 2017 brought a lot of attention. A
total solar eclipse, where the moon blocks the suns light for a short time, was
visible across the United States. This was the first total solar eclipse that
had been visible in the continental United States since 1979. I was fortunate
enough to be very near the “path of totality”, that is the line along which the
eclipse crossed the United States, plunging a narrow strip the earth in near
total darkness for a few minutes in the middle of the day.
There was
tremendous media buildup prior to the eclipse, and there was concern by public
safety agencies in the areas where the eclipse was going to pass, that the
large crowds would be an issue.
In addition to the
huge crowds, there was a large response of scientific researchers on hand to
observe and record the eclipse. The National Aeronautics and Space Administration
(NASA) had multiple aircraft flying, including their WB-57 high-altitude
research planes, up “chasing” parts of the eclipse as it crossed over the
country. NASA provided continuous media coverage of the eclipse as it moved
from the Pacific Ocean on to the Oregon coast. NASA has an excellent web site
set up with all things about the eclipse and what they were doing with it: https://eclipse2017.nasa.gov
Here is a list of
likely VHF and UHF aircraft frequencies that would be used by NASA aircraft.
Listeners in other regions of the country have confirmed some of these as in
use by NASA aircraft, particularly by the NASA fleet aircraft that fly between
NASA facilities in Houston, Florida and California. Keep these in your scanner
and see what you hear:

Besides NASA, the
National Oceanic and Atmospheric Administration (NOAA) flew some aircraft to
observe and record the eclipse. I did not have any luck catching the NOAA air
traffic on any agency specific air-to-ground frequencies, at least in the
Portland, OR area.
VA IDAS Trunking System
New Federal IDAS
Trunked System
Recently, a friendly
source in the Seattle, Washington area passed along information on what
appeared to be a new, three-site IDAS trunked system in the Puget Sound area. IDAS
stands for Icom Digital Advanced System, which is an Icom trunked protocol
using the NXDN open standard developed by Icom and Kenwood.
The frequencies
that have been identified with this system are 408.0375 MHz, 408.4250 MHz and
410.3250 MHz. So far, the system has only revealed these three original site
frequencies that were first noted. The frequencies are all using NXDN digital
mode, so they can be monitored with the TRX models of Whistler scanners or
using SDR radios with the appropriate software. The three sites all seem to
carry the same voice traffic simultaneously.
By listening for
several days, it was determined that the likely user was the Department of
Veterans Affairs Medical Centers. There are two VA Medical Centers in the
Seattle area – the American Lake facility in Tacoma, Washington and the Seattle
facility in Seattle, Washington. https://www.pugetsound.va.gov/locations/directions.asp
So far, the IDAS
trunked system appears to be used by maintenance and shuttle transportation. VA
Security has been reportedly using UHF P-25 repeaters at the Seattle area VA
facilities, but has also been reported to have talk groups on the federal VHF
Integrated Wireless Network (IWN) trunked system that supports a majority of
federal agencies in the region.
