In versions for the USA (indices "B") AMPS bands 824-849 and 869-894 MHz are cut out. (В версиях для США (индексы "В") вырезаны полосы AMPS 824-849 и 869-894 МГц)From The RadioReference Wiki
Cell blocked (or cellular blocked) is a phrase applied to scanners and wideband receivers manufactured for sale in the US which denotes that they comply with the provisions of PL 102-556, which amended Section 302 of the Communications Act (47USC302) to prohibit manufacture, importation, or certification of scanners which could receive the frequency band allocated for analog AMPS cellular telephony, "the frequencies allocated to the domestic cellular radio telecommunications service": 824-849MHz 869-894MHz

Morse Code for Survival
The Morse code for "A"
The Letter "A" with the 'Dit" and "Dah" placed on the letter as a memory aid.
In the event of a serious crisis, communication will be a challenge to say the least.
You will likely have to deal with power outages, inoperable cell phones, and the need to communicate covertly. In this kind of circumstance Morse code is a godsend. It requires little to no power or technology and very few people are able to interpret Morse code communication. In this day and age Morse Code is a lost skill, yet fortunately it is very easy to learn!
The above based mnemonic Braden-Powell included in the Girl Guides handbook in 1918

Essential Modern Survival Kit
Portable water in suitable containers for inmediate drink-ability, and a water filter for purifying after you run out of bottled water
FOOD
High calorie foods such as high calorie energy bars or MRE (meals-ready-to-eat] are vital to mantain sufficient energy to keep going
EXTRA CLOTHING
Even if it's warm outside, if you get in trouble without extra clothes, hypothermia becomes a risk.
BODY WARMERS
Bring reflectrive "aluminized" space blanket or survival blanket to retain body heat, catalytic heater and bottled gas fuel
SHELTER
Small tent, tarp with grommets, large plastic trash bag as poncho or expedient shelter roof
SUNGLASSES
There are some grate sunglasses out there that will enhance your vision, provide polarization for water or snow, and will prevent eye fatigue
SANITATION
Toilet paper, hygiene products, soap, hand-towel and any other body care products you may need
FIRST AID KIT
Keep at least the basics: band aids, sterile, gauze, desinfectant, first aid manual, medical tape, medical scissors, disposable gloves, tweezers, cotton swabs and a thermometer
EXTRA CASH
Extra cash will enable you to purchase the supplies you did not include and other necessary items
MEDICATIONS
There should be at least an even-day supply of any prescription and non-prescription medications used by family members
MATCHES
Keeping a lighter and a fire starter in addition to matches are a good idea
MAP
Simply having a good map of the region you're in could get you out of trouble
COMPASS
Is ideal for establishing bearings while used in conjunction with a map
FLASHLIGHT
And extra batteries. A LED flashlight, preferably a head-mounted style, is the best choice
PERSONAL DOCS
Important personal documents like proof of address, insurance policies, birth certificates and passports should be stored together in an area with easy access in case of a natural disaster
WEATHER RADIO
A small weather radio will keep you informed of the conditions outside and where to seek shelter or emergency personnel during and after a natural disaster
CELL PHONE
The towers may be down following a natural disaster, but emergency personnel will get them repaired fast for communication

RTL-SDR Multipurpose Dipole Antenna Kit
Designed for temporary outside usage only, not for permanent outdoor mounting.
- One dipole antenna base with 60cm RG174 cable and SMA Male connector. This is the dipole base where the telescopic antennas connect to. The short run of RG174 is decoupled from the base elements with a ferrite choke. This helps to prevent the feed line from interfering with the dipole radiation pattern. On the inside there is a 100 kOhm resistor to help bleed off any static. The dipole has a 1/4 inch female screw on the bottom, which allows you to use standard camera mount products for mounting.
- One 3 meter RG174 coax cable extension. This coax cable extension allows you to mount the antennas in a place that gets better reception. E.g. outside on a window, or higher up.
- Two 23cm to 1 m telescopic antennas. The telescopic dipoles are detachable from the dipole base via a M5 thread which allows for greater portability and the ability to swap them out. These long telescopic antennas cover VHF to UHF.
- Two 5cm to 13cm telescopic antennas. These smaller antennas cover UHF to 1090 MHz ADS-B, and even still work decently up to L-band 1.5 GHz frequencies.
- One flexible tripod mount with 1/4" male screw. This piece allows you to mount the dipole on a variety of different locations. E.g. a pole, tree branch, desk, door, window sill. The legs of the tripod are bendy and rubberized so can wrap securely around many objects.
- One suction cup mount with 1/4" male screw. With this mount you can mount the dipole on the outside of a window, on a wall, car roof/window, or on any other smooth surface. To use first clean the surface with window cleaner or isopropyl alcohol.
