Background Notes and Histories on Frequencies of the Lists.

Low Band VHF Frequencies:

LOWBAND VHF | PKDOT | 042.9800 FM | PREPPER LOW SIMPLEX
42.98 MHz is an old Low Band VHF itinerant business channel with a 2 watt limit. It is the Pink Dot channel, for those who are familiar with the Blue Dot, Red Dot, Purple Dot, etc. and similar "Color Dot" series used by 2-way radio marketing and event rental radios. Very few businesses still use VHF Low Band, because most have gone to cell phones. So the handhelds, portables, or mobiles for it are cheap at flea markets, garage sales, and online auctions. Also, 49 MHz walkie talkies and headsets can be modified for this frequency by changing the crystals. Useful for patrols and tactical communications. All scanners can receive this channel.

LOWBAND VHF | LOW | 033.4000 FM | SHTF SURVIVAL
33.4 MHz is an ancient Low Band VHF FM itinerant business channel with a 1 watt limit. Popular among reenactors, survivalists, and bulletproof-radio enthusiasts using old military surplus manpacks or military handheld sets on this channel (especially PRC-77). The reason they use 33.4 is probably because it is the only low power itinerant channel that old green manpacks can select with their 50 kHz or 25 kHz channel spacing dials. At low power in the field, they aren't bothering anybody. Useful for patrols and tactical communications. All scanners can receive this channel.

HAM VHF | 6M | 051.0000 FM | HAM PREPPER SIMPLEX
51.0 MHz is a ham radio 6 meter FM simplex channel widely used by operators with all types of Low Band VHF military surplus radios. The frequency is compatible with normal ham radios and is not on a repeater channel. If military radio tone squelch (150 Hz) may be used, it is compatible with civilian radios PL 151.4 Hz. Useful for patrols and tactical communications. All scanners can receive this channel.

Some interesting older "green" military surplus radios common for Low Band VHF frequencies:
Military manpack set PRC-9, AN/PRC-9 (27.0-38.9 MHz FM) continuously tunable
Military manpack set PRC-10, AN/PRC-10 (38.0 to 54.9 MHz) continuously tunable
Military manpack set PRC-77, AN/PRC-77 (30-52.95; 53-75.95 MHz FM) channel spacing 50 kHz
Military manpack set PRC-25, AN/PRC-25 (30-52.95; 53-75.95 MHz FM) channel spacing 50 kHz
Military handheld set PRC-68, AN/PRC-68, PRC-68A, PRC-68B (30-79.975 MHz FM) channel spacing 50/25/12.5 kHz
Military handheld set RT-1547/PRC-126, AN/PRC-126 (30-88 MHz FM) channel spacing 25 kHz
Military handheld set AN/PRC-128  (30-88 MHz FM) channel spacing 12.5 kHz
Military manpack set AN/PRC-119 (30-87.95 MHz) channel spacing 25KHz
Military radio set AN/PRC-117 (30-90 MHz) channel spacing 25KHz

High Band VHF Frequencies:

LAND SAR VHF | SAR FM | 155.1600 FM | SEARCH & RESCUE
155.16 MHz FM Simplex is the (ground or land) SAR (Search And Rescue) National interoperability channel in USA. It is widely used by government and civilian SAR teams for field communications and interaction with governmental, law enforcement, or fire operations in the field. This channel is also known as SAR WFM or SAR NFM and it requires an FCC  license to transmit on it. All scanners can receive this channel.

MARINE VHF | 16 | 156.8000 FM | SAFETY CALLING
156.800 MHz FM Simplex is VHF marine channel 16, the international primary Marine Safety, Emergency, and Distress guard channel worldwide. It is widely used and monitored by all boats, ships, and watercraft. All scanners can receive this channel.

MARINE VHF | 72 | 156.6250 FM | MARINE PREPPER
156.625 MHz FM Simplex is VHF marine channel 72, an international ship-to-ship or HT channel worldwide. It is widely used on boats, ships, and watercraft. It is designated for non-commercial use, is common for HT-to-HT informal communications, and is normally clear of commercial shipping or port operations. It is usually not monitored by coast guards. All scanners can receive this channel.

AIRCRAFT VHF | GUARD | 121.5000 AM | EMERGENCY DISTRESS
121.5 MHz AM is the Aircraft Emergency Frequency also known as the Guard Channel or International Air Distress (IAD) or VHF Guard. It is widely used and monitored by all aircraft, Air Traffic Control, defense aircraft, and towers. This was the primary crash beacon frequency for many years, up until newer 406 MHz UHF systems such as PLB, ELT or EPIRB emergency beacons became mandatory aboard aircraft in 2007. Transmissions on 121.5 MHz may bring teams of Search and Rescue authorities with direction finders looking for the transmitter. Some scanners can receive this channel.

HAM VHF | 2M | 146.5200 FM  | HAM CALL SIMPLEX
146.52 MHz FM Simplex is widely known as the ham radio 2 meter Calling Frequency. It is the most widely monitored simplex frequency in USA, but it should not be depended upon for emergency 911 type calls, because there are no organized first-responders on it. It is the most likely local ham radio FM Simplex channel to be activated in SHTF scenarios, especially when infrastructure and repeaters are down. All scanners can receive this channel.

HAM VHF | 2M | 146.5500 FM | HAM PREPPER SIMPLEX*
146.55 MHz FM Simplex is one of very few ham radio 2 meter frequencies widely coordinated for FM-Simplex-only throughout USA. *It is the only 2 meter simplex channel compatible with bulletproof military surplus radios (AN/PRC-127, etc) and forest-fire radios (Bendix HTs, etc). These types of radios have 25kHz channel spacing, and are in wide use by ham radio survivalists/preppers. Useful for patrols and tactical communications. All scanners can receive this channel.

3.818 MHz LSB is a ham radio Lower SideBand night regional frequency in the 80 meter band available to General license (or higher) operators in USA. It is on the channel list of several survivalist and prepper networks, including an active weekly net by TAPRN (The American Prepper Radio Network). HF SSB radios and some military surplus manpack radios can transceive on this channel. Shortwave receivers with LSB or BFO can receive this channel. Most scanners can not receive this channel due to the use of Single SideBand.

CB Band and Freeband HF Frequencies:

CB AM | 3 AM | 26.9850 AM | PREPPER CB
26.985 MHz AM is CB Channel 3. Useful for common tactical patrols and local area communications between vehicles and bases. Channel 3 CB is on the channel list of several survivalist and prepper networks. Shortwave receivers can receive this channel. Some scanners can receive this channel.

CB AM | 9 AM | 27.0650 AM | EMERGENCY CB
27.065 MHz AM is CB Channel 9. In USA, the radio regulations designate this as the Emergency and Travelers' Assistance Channel in FCC rules 47CFR95.407(b). It is widely used by CBers during emergencies, but it should not be considered a 911 type channel because it is not reliably monitored by any first-responder organization. Some CB radios have a dedicated Channel 9 button. Shortwave receivers can receive this channel. Some scanners can receive this channel.

CB SSB | 36 USB | 027.3650 USB | SHTF SURVIVAL
27.365 MHz USB is CB Channel 36 Upper SideBand. Highly useful for long range patrols and wide local area communications, espeically between vehicles and bases up to about 20 miles. Channel 36 USB CB is on the channel list of several survivalist groups. Shortwave receivers with USB or BFO can receive this channel. Most scanners can not receive this channel due to the use of Single SideBand.

CB SSB | 37 USB | 027.3750 USB | PREPPER CB SSB
27.375 MHz USB is CB Channel 36 Upper SideBand. Highly useful for long range patrols and wide local area communications, especially between vehicles and bases up to about 20 miles. Channel 37 USB CB is a prepper listed frequency. Shortwave receivers with USB or BFO can receive this channel. Most scanners can not receive this channel due to the use of Single SideBand.

CB FREEBAND | 38 GAP | 027.3780 USB | SHTF SURVIVAL

It is useful for long range patrols and wide local area communications, especially between vehicles and bases up to about 20 miles. This frequency is clearer due to less interference and has longer distance range than normal CB channels for SHTF groups using CB SSB radios with unlocked clarifier. Shortwave receivers with USB or BFO can receive this channel. Most scanners can not receive this channel due to the use of Single SideBand.

CB FREEBAND | E 2 HI | 027.4250 USB | SHTF SURVIVAL
27.425 MHz USB is a CB freeband Upper SideBand channel in extra channels, about 2 channels above normal CB channel 40. For CBs with extra channels in bands, it is channel 2 of the band just above normal CB band (usually Band E). It is useful for long range patrols and wide local area communications, especially between vehicles and bases up to about 20 miles. This frequency is clearer and has longer distance range than normal CB channels for SHTF survivalist groups using radios with extra upper high channels. Shortwave receivers with USB or BFO can receive this channel. Most scanners can not receive this channel due to the use of Single SideBand.
 
Freeband
Freeband refers to unlicensed transmitting on the frequencies above, below, and in between normal HF radio bands. CB radios can be modified to get freeband channels. Freebanding is communicating on the freeband frequencies. Freeband frequencies around 27 MHz CB have been widely used by thousands and thousands of freebanders worldwide over the past 40+ years.

AM Amplitude Modulation
AM is the basic modulation mode in standard CB radios. It is good for short range communication with common CB radios and CB HT (handheld) radios or walkie talkies. Some CB radios also have Single Sideband (SSB). AM is prone to more interference and doesn't go as far as SSB.

Upper SideBand (USB) or Lower SideBand (LSB)
Single SideBand (SSB) CB radios are very popular for freeband. SSB is by far the best freeband mode. LSB is mostly used for local area and "skip talking" in English language in North America. USB is used often for long distance, International communications, or Spanish language in North or South America. The choice of which sideband to use is not etched in stone. USB is usually selected for prepper and SHTF Survival channels because it is clearer and more compatible with various types of radios.

Freeband Radios
Freebanders use one of the following types of radios to talk on these channels:

1. CB radio modified with "extra channels", "high channels", "expanded", or "expanded clarifier".
2. Ham "10 meter" SSB radio that has been modified for 11 meters.
3. Export CB SSB radio, often with Band switch ABCDE or ABCDEFG.
4. Ham HF SSB radio modified for general coverage transmit.
5. Commercial land mobile HF SSB radio.
6. Marine HF SSB radio.
7. Military surplus HF SSB radio or manpack.
8. Aeronautical HF SSB radio.

Freeband Radio Rules
"License? They don't need no stinkin' license!"---an often misquoted saying that applies well to freebanders. Freebanders don't have a license for these frequencies. CB radio rules, channels, modes, and frequency bands vary quite a lot from country to country. 99.99% of the time, the governments don't enforce radio rules or regulations on the common freeband frequencies unless someone uses a high power linear amplifier to create radio interference for neighborhood TV sets or other services. Enforcement pretty much gave up on this part of the spectrum a long time ago, and it is mostly considered "sacrificial spectrum" in the "wild west of radio". However, there are some frequencies in this spectrum that wise freebanders avoid. For example, between 28.000 MHz and 29.700 MHz, the 10 meter ham band, they are very likely to be tracked by ham operators and reported to the authorities. In USA, many CB truck drivers don't heed freebander frequency caution; they often talk on 28.085 MHz (sometimes known as "high 19") where they are easily tracked down by hams. Their trucking companies are often fined by FCC, and the drivers get fired. Most freeband operators look down upon that kind of carelessness.

Why Freeband
So, with all the issues surrounding it, why do people use freeband? Simple. It works. The frequencies are clear; free of the busy chatter and interference of normal CB channels. Freeband goes further than other common unlicensed radios like FRS, GMRS, or MURS. Freeband distance range is similar to ham radio 10 meter HF SSB. Freeband is compatible with the CB radios. The radios are widely available, inexpensive, ubiquitous, and easy to use.

Freeband Operating Methods
Freebanders usually use fake callsign numbers or letters to anonymize themselves. These are different callsigns than the ones they use on Normal CB Channels. If talking about locations they are usually vague or use informal code words known only to each other. Freeband users often are normal CB users who just want some of the long distance communication advantages of ham radio HF SSB, but without a license. Freebanders go in between or outside the normal CB channels to achieve long distance communication that would be nearly impossible on the normal 40 CB channels. Radios with expanded channels, Export CB Bands, or VFO feature can transmit above the CB band. Even a very old used SSB CB modified with expanded clarifier slider can tune slightly off frequency to the Drop Gap (LSB) or High Gap (USB) clear space between channels. To avoid detection, freebanders often transmit from vehicles instead of base stations. Long distance can be achieved by parking away from power lines on an isolated hilltop, side road, or open parking lot. By limiting conversations on the freeband channels to only what is necessary and avoiding long-winded chat or skip-talking, the detection footprint is minimized. Freebander groups usually have one or two frequencies they use as a "call channel" for initially making contact, and then select another frequency at random for continued conversation. They usually avoid talking about specific activities or using coarse language that might make them stand out. Instead, they try to blend in casually.

Freeband Radios for SHTF
Freeband-capable CB radios are well-suited to SHTF survival situations. The direct radio-to-radio distance range of freeband CB SSB is much greater than a ham VHF/UHF HT or MURS or FRS or GMRS. This is because 27MHz travels further than line-of-sight, due to ground wave that can extend the range over hills and valleys. A big advantage is that inconspicuous CB SSB radios modified for freeband look exactly like normal CB radios. With a good antenna, these radios can usually cover a wide range around a local town or county area. The radios run on 12 Volt DC, can be powered for many days on a car battery, and then recharged with solar or alternative energy. Military surplus manpack HF SSB radios can be used for freeband. Marine HF SSB radios can be modified for freeband, and some Aeronautical HF radios can work on freeband. Keep in mind that many of these radios are only capable of Upper SideBand, so USB is usually selected for SHTF survival HF freeband frequencies.

Some possible freeband radios which have 'extra channels' in the 11 meter band 27 MHz.
(AM/SSB or AM or AM/FM or AM/FM/SSB)
Note: Most of these are either marketed as 10 meter ham radios, or banned for import into USA, or otherwise looked upon with disdain by do-gooders; so they may show up on auction sites, flea markets, non-mainstream cb places, cb websites, or under-the-counter at truck stops.
