Check with you local ARES or RACES groups or CERT if you are not HAM licensed for starters
also research https://amrron.com/ for the CH3 project; MURS, FRS and CB channel 3
Good luck!

146.52 when traveling and also at home. I was surprised how many times at home I have heard hams passing thru the area on 146.52, calling looking for info on repeaters, other simplex, location info, or just wanting to talk. I keep 146.52 in scan on my FT2900R in my Jeep when traveling, and have made numerous contacts, both here in Texas, and along the coast on a couple of out of state trips.

In a time of national or international distress, I would scan the 40m phone band for domestic information and the 20m phone band for international info.

Edit: And then tune into the 80m phone band to find out what all the conspiracy folks think.

This side of the pond it would be 145.500 on 2m & 433.500 on 70cm both are National Simplex Calling Frequencies.

Since the scanner I use to monitor the calling frequencies is FM only:
29.6
52.252
146.52
223.5
446.00
906.5
1294.5

They are all programmed in the transceivers also to allow a quick response. The reason for the separate scanner is to allow continual monitoring even while the transceiver is in use on another frequency.

This. I monitor 146.42 (AmRRON/TAPRN) along with several local repeaters on my radio when home. 42 simplex is the main channel on all my mobile and portable VHF rigs.

USA-PREPCOM: A suggested radio coms standard for USA preppers

Original Concept By R-UK, as Adapted for US Band Plans by KE4SKY

The objective of the USA-PREPCOM is to coordinate between licensed amateur and unlicensed citizens band, Family Radio Service, Multi-Use Radio Service and other USA based survivor radio stations following a major disaster in which conventional telecommunications have ceased.

For easy mnemonics the standard is the RULE OF 3S
3 is the important number. Remember it!
The 3 parts to the Standard are:

• 1/3:WHEN (Time coordination so we all know WHEN to call and listen)
• 2/3:WHERE (Frequency coordination so we all know WHERE to call and Listen)
• 3/3:HOW (Radio set-up so that everyone’s transmissions are compatible)

What’s this document for?

It is intended that this document be printed and stored in a water and light-proof pouch which is to be kept with stored radio equipment intended for disaster communications.

PART 1/3 =WHEN
Everybody looking to communicate needs to coordinate the time at which to do so.
By coordinating times and limiting operational time window precious electrical power will be conserved

Rule of 3s again:
Start communication sessions On the hour
Every 3 hours (starting 00.00h)
For 3 minutes calling and listening, if nothing heard, close the station and try again at next scheduled time.

Note, if a contact is made it is good practice to move communications to another channel / frequency so that the emergency calling channel is freed for other users
There is no requirement to end it after the magic 3 minutes, it can continue as long as required, but bear in mind power consumption.

PART 2 =WHERE
Where relates to Frequency coordination so that everyone is also communicating on compatible frequencies, failure to coordinate frequency is like not knowing the direction in which to flash a torch to signal to someone at night. We need to know exactly where to send and where to look.

Rule 2 is broken into two parts 2a for simple License-free transceivers (CB, FRS and MURS walkie-talkies), whereas 2b Ham is a full version incorporating both license-free and USA Ham frequencies.

PART 2a =WHERE License free

So for license free, the RULE of 3 continues. Set your radio to one of the following:
• AM only CBs = Channel 03 26.985 Mhz AM US band
• SSB capable CBs = Channel 33 27.335 MHz USB
• FRS and GMRS = Channel 03 462.6125 MHz FM- NB (CTCSS/ DCS code turned OFF)
• FM-NB only MURS = Channel 03 151.92 MHz FM-NB MHz (US band)
PART 2b/3=WHERE Full version

PART 3/3=HOW to set up the radio and transmitting antenna

3.1 Identifying and setting the operating MODE of your radio

In all descriptions there are annotations FM/USB/LSB/FM NB. These are the different TYPES/ FORMATS/MODES of signal that radios can transmit.

It is essential that sending and receiving stations are using identical transmission TYPES otherwise they will not be able to hear one another even if transmitting and receiving on the same frequency at the same time.

Look at your radio: If it has a MODE knob it will allow you to select the modes required. If it does not have a mode knob and it’s a CB it will almost certainly be FM only. This should be confirmable by looking for a label or stamp of conformity on which the letters FM will be shown.

FRS equipment is only manufactured in FM variety so no choices to make.

3.2 POLARITY of your antenna.

For CB the antennas must be vertical
For FRS and GMRS antennas must be vertical
For Ham frequencies below 28MHz antennas must be HORIZONTAL
For Ham frequencies in FM mode above 28MHz antennas must be VERTICAL
For Ham Frequencies in LSB/USB mode above 28 MHz antennas must be HORIZONTAL

Cross polarization is only a big deal in direct path communications, anything involving reflections or mutlipath tends to smear the polarity. With direct path and cross polarization you can have up to about 30 dB of isolation, however typically it is less than that. But bounce that signal off anything one time and the polarization sensitivity falls off dramatically.



" For CB the antennas must be vertical"

Many, many, CBers work on the flat side. Often horizontal is used for DX and vertical for local comms.

" For Ham frequencies below 28MHz antennas must be HORIZONTAL"

Uhhh...no. I know many hams who participate in reliable communications that have never owned a horizontal antenna. Space limitations, structure limitations, the desire for a specific take-off angle, etc, often drive hams to a vertical antenna on HF.

I personally prefer horizontal antennas on HF, and the majority of my HF antennas are horizontal, but verticals also have some positive traits.

" For Ham Frequencies in LSB/USB mode above 28 MHz antennas must be HORIZONTAL "

To be sure, above 30 MHz vertical for FM and horizontal for weak signal (SSB or CW) is the convention. But I know a lot of hams on 2M and 70cm on SSB and only a vertical. Also circular polarization on these bands has a real advantage. With a CP antenna you can work EITHER vertical or horizontal stations with only 3 dB of polarization loss. And it is great for working sats, with their unpredictable polarization. The only time CP is bad is when you have another CP station with opposite polarization. A left hand CP station trying to work a right hand CP station can have up to 30 dB of isolation, and that is less reduced by reflections than with opposing linear polarization signals.

You do know, don't you, that the polarity of the signal changes as it bounces off of things, including but not limited to inversion layers, dust clouds, rain, man made objects, vegitation, or geological formations . What you said would be true for a direct line of sight signal. Even then the cross polarization loss at 90 degrees is 20dB +/-.

I have made many 6/2 meter USB contacts using mobile vertical antennas.

For me when at home I monitor the following:
1: 2.182.00mhz USB for Marine Distress/Emergency
2: Various calling in the 20/40/60 and 80 meter bands. Depends on the time of day, the day and time of year.
3: 28.400.00 mhz USB which seems to be a unofficial calling frequency for the Technician portion of the 10 meter band.
4: 50.110 USB (6 meter DX calling) and 52.525 FM (6 meter FM calling)
5: 146.520 fm (2 meter calling) and 446.00fm (70cm calling)
6: 155.160 National S&R Mutual Aid
7: 121.500 mhz AM for Aircraft Emergency

When Mobile:
1: 146.520
2: 446.000
3: 155.160
Various repeaters depending on location.

HF 7.272.00 on 40 meters if I'm not monitoring another frequency for net etc.
