Bedford County Communications Guide
This guidebook was designed by the Bedford County Amateur Radio Society to inform. While most of the information is geared towards Amateur Radio Operators (hams) in and around Bedford County, we hope it can provide a powerful resource for anyone interested in radio communications technology. A good portion of this text is made to be introductory, so it should prove useful for you even if you are not from Bedford County.
If you are not interested in wireless communications, this book will be less useful, but could still contain some valuable information. It provides contact information for a number of emergency response organizations. We all know to call 911 for immediate emergencies. But do you know how to get in touch with the Red Cross, or PEMA, or FEMA? How would you check on relatives during a flood with no working phone?
About Bedford County
Founded in 1771, Bedford County has a rich history predating the birth of the Union. Bedford County is a small community in central Pennsylvania with approximately 50,000 residents and 25 townships spread over 1,017 miles of mountainous terrain. Each community is typically divided along geographical boundaries such as a mountain ridge or body of water.
The Bedford County Amateur Radio Society was formed in 1959 in order to support Bedford County. BCARS was formed by Bedford County reseidents such as Tom Scott K3ETC, and Arden Moser (K3MIU). Several of these “founding fathers” are still in the area today. One of their first tasks was to take charge of the Bedford County Civil Defense, communications system, which as that time was housed in the county court house basement.
Throughout the years, BCARS has maintained a close relationship with Bedford County Emergency Operations, providing communications as needed in disaster situations, as well as assisting with communications at county events. As such, the club has maintained its presence with first the Court House, then the county 911 center, and ultimately moving with the 911 back into the renovated and expanded county court house in 2006(?).

Citizens Band (CB)
Citizens Band Radio, commonly referred to as CB is an unlicensed short-range radio service suitable for both personal and commercial uses. In the US, CB communications is set at 27Mhz (the “11-meter band”). Originally a 23-channel service, it has since been expanded to 40 channels. Conventionally, channels 1-35 use “Amplitude Modulation” at a maximum of 4 Watts while Channels 36-40 use “Single Side Band (SSB)”. SSB mode is allowed to use up to 12 Watts of power, giving it an advantage over the AM channels. Technically however, most modern CB radios can do SSB on any channels. This is discouraged as it would cause interference with those using AM on the same channel.
The FCC has set aside channel 9 for emergency use. In most regions, emergency service will listen on channel 9 for emergency calls. Many modern CB radios will also listen on channel 9, even if the operator is actively tuned to another channel. If a broadcast comes in on channel 9, the CB can play it, alerting as many people as possible to the emergency. While not a regulation, most operators consider channel 19 the “common call” frequency for AM modes and channel 36 the common call for frequency for SSB modes.

MURS - is an unlicensed “multi-use radio service” limited to 2 watts. No license is required, but some companies (such as Wal-Mart) use MURS radios and tend to get upset when non-employees start coming in on their handhelds.
FRS - “Family Radio Service” limited to 0.5Watts (unlicensed)
GMRS - General Mobile Radio Service is a licensed commercial band permitting up to 50 watts. Hybrid FRS/GMRS radios exist. Channels 1-7 are shared between FRS and GMRS, however FRS radios are limited to the 1/2 watt restriction. Licensed GMRS and unlicensed FRS operators can communication on channels 1-7. Channels 8-14 are FRS only and 15-22 are GMRS only. The channel numbers listed below is the most common for a hybrid radio, though a GMRS only radio will have different frequencies per channel.

Understanding Amateur Radio
What is Amateur Radio?
Amateur Radio means many things to many people. However, first and foremost, it is a hobby. People get into amateur radio because they have found something in it that they enjoy. For some, it's the idea of being able to talk to someone half a world away without relying on any sort of infrastructure. A radio, a battery, and some wire will get you on the air. Others just want to talk to local friends on the repeater. Still others are into building things, and amateur radio is a great outlet for that. Up until recent years, “technical people” have been in the minority. Finding a diverse group of technically minded people to talk with has always been a challenge. Amateur Radio provides a medium for technical people to come across each other and enjoy a sense of community.
While there is a licensing test to take (involving technical questions and some legalese), the learning curve is not that hard. You see, Amateur Radio operators are granted the largest chunk of the wireless spectrum and given the most amount of freedom in how they can operate. A commercial radio station has to operate within very tight restrictions. Unlicensed operators must use FCC Part 90 certified low-power, “locked down” equipment. But in Amateur Radio, the onus is on the operator to ensure that they are within regulations. The test is in place to ensure that an aspiring operator understands what they are working with and the potential interference that they can cause.
Does this mean you have to be a technical genius in order to get into Amateur Radio? *Absolutely not!** The test requirements are designed to allow as many people as possible to get on the air. Children as young as 8-years old have studied for and passed the FCC License exam. Many Boy and Girl Scouts will seek out an amateur license as part of a merit badge requirement. Young, old, deaf, and blind people have taken and passed the test. What's a deaf person doing on the radio? Most likely they're participating in a digital mode such as Radio TeleType (RTTY). From voice communications to packet radio to talking with the Internation Space Station, Amateur Radio has just about something for everyone to enjoy.
Amateur Radio is first and foremost a hobby to be enjoyed. In order to keep it as enjoyable as possible, operators have developed a code of conduct for operating that is in some ways more important than the FCC regulations. This common courtesy goes beyond “keeping it clean” and includes tenants such as leaving a pause for other operators to break in and managing “round table” type discussions.
Simplex Radio communications (sometimes referred to as half-duplex) is one of the most common and simplest form of communication. Operating simplex means that you are transmitting and receiving on the same frequency. Typically, only one transmitter is active at a time within a coverage area. Once the radio operator completes their transmission, they stop transmitting and allow other operators to respond with their own transmission. If two operators attempt to transmit at the same time, this is called doubling or getting stepped or walked on. If a lot of operators attempt to transmit at the same time on the same frequency, this is called a pile up.
The most prevalent and active use of simplex radio is probably CB channel 19. The bulk of CB radios sold in the US default to channel 19. On any given day near any given road, finding activity on channel 19 is not uncommon in the least.
For amateur radio in the US, the frequency 146.520 is reserved as the “National Simplex Calling Frequency”. Many ham radio operators monitor this frequency at home and while traveling. While activity on this frequency has been on the decline as linked repeater systems become more common, there is a concerted effort to make this channel more active once again. The Interstate Highway Rest Area Society1) is promoting an annual event for hams to operate out of rest area parking lots. This event (RAOTA)2) is to take place annually the weekend following Thanksgiving, the busiest travel period of the year.
Duplex and Repeaters
Repeaters typically work in two modes: simplex and duplex. A simplex repeater receives on one frequency, records what it receives, and then broadcasts it again on the same frequency once the original transmission stops. A duplex repeaters will listen on one frequency and transmit simultaneously on another. Duplex are the more common type of repeater as they allow for more continuous communication.
Some repeaters use a ”pl tone”(also called ctss or sub-audible) tone to reduce interference. With a PL Tone, the end-user transmits a pre-configured tone ranging from 67.0 Hz to 250.3 Hz along with their transmission. The repeater will only activate if it hears the appropriate tone. This prevents the repeater from keying up during spurious transmissions. The PL tone is removed from the final output audio of radios receiving the broadcast.
In order to use a duplex repeater, you need to understand how the frequencies work (though many new radios will have an “auto repeater” feature that figures this out automatically). We will use the BCARS “K3NQT” repeater for an example. Typically, a repeater is listed by its transmit frequency (Tx). BCARs 2M transmits on 145.490, so you would tune your radio to receive on 145.490 in order to hear it. However, the BCARs 2M repeaters listens on a “negative offset” frequency of 144.890 (0.6Mhz 'down' from 145.490). So in order for you to talk to the repeater, you need to program an offset into your radio so that it transmits on 144.890. While the procedure varies from radio to radio, it usually involves two settings: 1) the offset type of + (postive), - (negative), or “none” (simplex) AND 2) the offset spacing. For BCARS 2M, the offset spacing is 0.6Mhz. The BCARs repeaters also use a PL Tone of 123Hz, so you would have to enter that in as a separate setting.
Because there are a large number of possible offsets (or splits) that repeaters can use, a standard has been adopted within the US for repeater pairs.
On the 2-meter band, the offset spacing is typically 0.6Mhz. If the repeaters Tx frequency is below 147Mhz, the offset is typically negative. If the Tx Frequency is above 147 Mhz, the offset is typically positive.
|Output Frequency||Input Frequency Offset|
|51-52||- 0.5 MHz|
|52-54||- 1.0 MHz|
|144.51-144.89||+ 0.6 MHz|
|145.11-145.49||- 0.6 MHz|
|223-225||- 1.6 MHz|
|440-445||+ 5.0 MHz|
|445-450||- 5.0 MHz|
Digital Modes refer to any mode where you send information in a mode other than voice or video. Occasionally HAMs will include Morse Code as digital, but others will disagree as it can be understood by the human ear. Excluding Morse Code, digital typically requires a computer or microcontroller in order to send and receive the information.
WPA ARES actively promotes using existing repeaters to send real-time digitial notices. It's not automated by any means. In this scenario, you would start off with voice, announce that you're going to send your digital message, wait for a voice “go ahead” and then send it.
Ideally, you would have at least person in the EOC (which would be the club room, if we had antennas) directing the emergency net with an ability to send and receive real-time digital. On the net, you would have to take turns between sending voice and sending digital. For this to work though, operators would need the fldigi program installed on their computer and for their computer to be able to hear the radio. While acoustically coupling works fairly good, a dedicated interface cable would definitely cut down on noise. If you have a computer with a soundcard, adding real-time digi takes only a bit of effort. I think we need to get more members setup with the fldigi software and perform a few practice NETs to give people practice.
Another option for short alerts is APRS (144.390 PL 100). There are a fair number of APRS users in our area and most of Bedford County is in reach of an APRS digipeater. Within the club itself however, not too many people have it. The club also doesn't have any form of APRS transmitter, though I am hoping to set one up. With APRS, you can send out bulletins that would get displayed on APRS capable radios (as well as PCs connected to an radio). We could send out bulletins such as “Tornado warning, emergency net on 145.490” and every APRS device in the area would receive it. An APRS compatible radio could even press a button and automatically tune one side of their dual-band radio to that frequency. APRS allows sending “public” broadcasts and you can send to individual operators by their call sign. Messages are limited to 3 lines of 67 characters each for a total of 201 characters. Shorter messages are better for propagation.
As a final option, there is packet. There are a couple BBSes in the area, such as N3NXO's MTDALLAS station on 145.05. This is a more dedicated mode with no room for voice. The advantage of using a BBS would be the CONVersation mode, which would be a form of text-based chat. Operators are able to connect to this BBS and drop into CONVerse mode to chat with other operators. You can also upload a file to a BBS and then others can download it. The Packet mode allows multiple operators to be transmitting text at once and the packet station will sort it all out and put the text in order. The big downside to packet compared to the other two modes is that it ties up a 2M radio. Even if you have a dual-vfo radio, one side of the radio is going to be monopolizing your antenna. However, if you have an older 2M radio without PL tones/repeater capabilities, it will make a good packet radio.
Somerset County has put together a really nice BBS infrastructure on 145.03. They have a couple packet stations deployed with a BBS to BBS “backbone” on 220Mhz.
Using software such as fldigi, you can use your computer to send and receive digital data in various modes in-between voice transmissions. If you already have a computer with a sound, the cost to entry is very low. Your computer's sound card can convert text to sound and transmit it out the speakers. Conversely, you can feed the radio's audio output into the computer's microphone to receive these transmissions. The best setup would involve a push to talk adapter and a pair of audio cables connecting the computer to your radio. However, if your radio supports VOX (voice operated transmit), you don't actually need the PTT circuit. For really low end, some people have had good success just holding the radio near the speakers and microphone and manually pressing the radio's PTT!
How is this useful? HAM works on a one-to-many or a many-to-many approach. If you need to send a list of information - be it people's names, supplies needed, or model & serial numbers, voice is very, very slow and prone to error. How many times have you had to ask an operator to provide their call sign more than once. Using phonetics such as Kilo-Bravo-Three is even slower and *still* error-prone. By typing this list up on your computer before hand, you can paste it into fldigi and send it relatively error-free in one transmission. Since this is not a continuous digital mode, you can take turns between voice and digital. This means you can send digital transmissions using existing repeaters.
Here is the fdigi beginner's guide.
|fdigi in action||Setting up for FM use|
fldigi also has several supporting programs.
- flwrap converts a digital file such as a photograph or ZIP file into ascii data which can then be transmitted over the radio.
- flsmg is a FORM manager that allows operators to fill out a standard form. You fill out the form in an easy to use graphical interface and then send it as pure ASCII. Receiving stations can view the raw text or open it in either their web browser or flmsg. The receiving station can then print out the form or email it from their computer if available. There are several forms included, but anyone can make their own form and distribute it locally. Not everyone needs the form on their computer to receive it (as the form will open in a web browser - no internet access needed). A standard form could be created just for Bedford County EMS if desired.

Comparison with Packet
Traditional packet operation typically requires a dedicated frequency. Packet stations perform beaconing and repeating of data, all under automatic control. It is quite common for multiple stations to transmit at the same time. There is no room for voice transmissions. “Real-time digitial” however, is manually controlled by human operators. There is typically a voice transmission in between each digital transmission. In essence, the data is controlled by voice. An operator getting ready to send will inform other operators of his intent. The receiving operator will announce they are ready “send your traffic” and if it was received properly “solid copy”.
Packet has its advantages. For instance messages can be sent from packet station to packet station automatically until it reaches its destination. A user of one node in Bedford, PA can send a message to a node in Warfodsburg, PA and be relatively confident that it will arrive within minutes. Packet nodes can also be used to send and receive email from the Internet at large (for example, using winlink). Packet BBSes often have what is known as a “CONVerse” mode where operators can “chat” in real-time on a channel.
However, packet has disadvantages in an emergency situation. First off, it excludes voice only operators. Second, since packet uses a “store and forward” method of sending messages between nodes, critical messages can be delayed minutes, hours, or even days (depending on how congested the channel is).
Automatic Packet Reporting System
For quick reference, here are the common APRS frequencies and PL tones to use in the US:
Ch1 “APRS VA ” 144.39 Voice Alert, CTCSS 100 for normal operations
Ch2 “APRS raw” 144.39 no tone squelch - for troubleshooting
Ch3 “APRSmute” 144.39 CTCSS 123 - for completely QUIET operation (substitute any private CTCSS tone you want)
APRS is most commonly associated with just location, but it is a full-fledged messaging system for radio operators. You don't even need a GPS to utilize APRS. At its core, APRS is a standard packet format for short messages with limited distribution. If that sentence confuses you, follow this scenario.
- Operator 1 tunes his APRS-equipped radio to 144.39Mhz (pl tone 100hz) and uses the radios built in controls to tap out a text message “Route I-99 Mile 39 washed out”.
- This message is transmitted from his radio and picked up by 4 other radios within his transmitter range
- These radios display the message on their screen and then retransmit the message again
- Each message has a built-in limit as to how far it could be retransmitted, typically limited to 2 or 3 retransmits. This prevents the local message from being relayed across the US. It keeps the message relatively local, based on the transmit power of each radio involved.
APRS messages are used to identify radio resources within an area. If an operator is able to connect a GPS to their APRS radio (or a location-aware computer to a non-APRS enabled radio), they can provide their exact location. Web services exist to view APRS resources within an area and to send them messages directly. ARPS messages can also include items like the frequency pair of a local repeater. Imagine driving into a new area and getting a message with a suitable repeater to use. The mere act of receiving the message tells you that you are in range to hear the repeater.
Many amateurs will connect a laptop to their APRS radio (or you can connect one to an older single-band radio or HT) to be able to view and interact APRS information on a full screen (and keyboard). If GPS enabled APRS users are transmitting nearby, they can show up on a map. You can send messages to them directly.
APRS nodes also act as a relay. You can specify a specific call sign to send an APRS message to (even if you don't see them in your list) and your message will be relayed from APRS node to APRS node until it reaches its destination.
