Getting Started on 2-Meter SSB

Try the "Other Mode" on 2 Meters

Bob Witte, KØNR
4 May 2003

2m SSB Frequency Range : 144.100 MHz to 144.275 MHz (USB)
2m SSB Calling Frequency : 144.200 MHz

In the past few years, a new breed of amateur radio transceiver has hit the marketplace --- radios that cover from HF through VHF/UHF frequencies. These radios include the ICOM IC-706, the ICOM IC-746, the Yaesu FT-100 and the Yaesu FT-847. This is not an exhaustive list since there are new radios being introduced every year with additional capability.

These radios include "all-mode capability" which means that they can operate FM, CW and SSB on the VHF bands. Clearly, FM is the most commonly used mode on VHF and UHF but having SSB opens up a whole new range of operating fun.

Why SSB?
FM is the most popular mode primarily due to the wide availability of FM repeaters. These repeaters extend the operating range on VHF and enable low power handheld transceivers to communicate over 100 miles. FM is also used on simplex to make contacts directly without repeaters. The main disadvantage of FM is relatively poor performance when signals are weak, which is where SSB really shines. A weak FM signal can disappear completely into the noise while a comparable SSB signal is still quite readable. How big of a difference does this really make? Perhaps 10 dB or more, which corresponds to one or two S-units. Put a different way, using SSB instead of FM can be equivalent to having a beam antenna with 10 dB of gain, just by changing modulation types. So this is a big deal and radio amateurs interested in serious VHF work have naturally chosen SSB as the preferred voice mode. (You will also hear them using Morse code or CW transmissions, which is even more efficient that SSB.)

Just as an example of what is possible on SSB, during one VHF contest I was operating portable on Garden of the Gods Road in Colorado Springs. I had just dismantled my 2M yagi antenna and was listening to 2M SSB on a short mobile whip antenna. Suddenly, I heard WA7KYM in Cheyenne, Wyoming calling CQ from about 160 miles away. I figured that with my puny little antenna and only 10 watts of power, there was no way he was going to hear me. But, what they heck, it was a contest and it would be more points so I gave him a call. To my surprise, WA7KYM heard me and we made the contact without much signal strength to spare. Now, to be accurate, this contact has more to do with WA7KYM's "big gun" station (linear amplifier, low noise preamp and large antenna array) than it had to do with my 10 watts and a small whip. The key point here is that this contact would not have happened using FM and was only possible because of SSB.

When and Where to Operate
The SSB portion of the band runs from 144.100 MHz to 144.275 MHz and Upper Sideband (USB) is used. The 2M SSB calling frequency is 144.200 MHz, so that is the first place to look for activity or to call CQ. One of the realities of 2M SSB operation is that many times, no one is on the air. There is just not that much activity out there, compared to 2M FM. Some amateurs get discouraged, turn off the radio and and miss the thrill of working distant stations during a band opening. To get started on 2M SSB, the trick is to get on the air at times when you know there will be activity--- during VHF nets and VHF contests.

Here in Colorado, the local Rocky Mountain VHF Plus net is on Monday night at 8:00 PM local time on 144.220 MHz (USB). This net is centered in the Denver area but VHF enthusiasts check in from all around Colorado. It is very common to have stations check in from the bordering states of Wyoming, Nebraska, Kansas, New Mexico or even Oklahoma. More information on the net and other VHF activities can be found at

There is also a 2M SSB net associated with the Amateur Radio Emergency Service (ARES) which meets at 7:00 PM local time on 144.220 MHz (USB). For more information, see

VHF Contests
Think of VHF contests as "VHF activity weekend" since they are a great opportunity to just get on the air and work most of the local 2M SSB enthusiasts. The main contests are the ARRL June VHF QSO Party, the ARRL January VHF Sweepstakes, the ARRL September VHF QSO Party and the CQ Worldwide VHF Contest in July. For more information, take a look at the article How to Work a VHF Contest at

The required equipment for getting started on 2M SSB is pretty basic - a transceiver capable of 2M SSB and a 2M antenna. If you own one of the rigs mentioned above then you are probably ready to go. The 2M antenna you already have is probably vertically polarized since that is what we use for 2M FM, both mobile and base stations. All of the 1/4-wave and 5/8-wave antennas that are commonly used for 2M mobile work are vertically polarized. Most omni-directional base station antennas such as those made by Cushcraft, Diamond, Comet, etc. are vertical, too. These antennas will work for SSB but most of the really active 2M SSB stations use horizontally-polarized antennas. Vertically-polarized stations can work horizontally-polarized stations but there will be a substantial signal loss (about 20dB?). If vertical is all you have, then give it a try. If you can get a horizontal antenna, then your results will be much better.

The most common horizontally-polarized antenna on 2M is a Yagi mounted so that its elements are parallel to the ground. There are a variety of horizontally-polarized, omni-directional mobile antennas, such as the HO antenna made by M2 (see

Get on the Air
This information is intended to get your started on your way to operating 2M on the SSB portion of the band. You will learn more as you get into it and you will find that most of the people hanging out down on sideband are friendly, knowledgeable and helpful. They are always happy to see new call signs on 2M sideband.

WARC bands

The WARC bands are three portions of the shortwave radio spectrum used by licensed amateur radio operators. They consist of 30 meters (10.100–10.150 MHz), 17 meters (18.068–18.168 MHz) and 12 meters (24.890–24.990 MHz). They were named after the World Administrative Radio Conference, which in 1979 created a worldwide allocation of these bands for amateur use. The bands were opened for use in the early 1980s. Due to their relatively small bandwidth of 100 kHz or less, there is a sort of gentlemen's agreement that the WARC bands may not be used for general contesting.

Throughout most of the world, the 30 meter band cannot be used for phone communications except in emergency situations. However, part of Region 1 (Africa, south of the equator, during daylight hours) is permitted to use phone. The USA limits amateur radio users to 200 watts peak envelope power on this band.

The ARRL and many other national entities recommend the NATO phonetics for Amateur Radio use as most Hams around the world recognize them. This alphabet dates from about 1955 and is approved by the International Civil Aviation Organization, the FAA and the International Telecommunication Union, and many National Amateur Leagues/Societies/Orgs. Note that different bodies prefer different spellings, so one also sees: Alfa Juliet Juliette Oskar Viktor]. As a matter of reference -- see URL:
NATO phonetic alphabet From Wikipedia, the free encyclopedia.

The NATO phonetic alphabet was developed in the 1950s to be intelligible (and pronounceable) to all NATO allies. It replaced other phonetic alphabets, for example the US military Joint Army/Navy Phonetic Alphabet ("able baker") and several versions of RAF phonetic alphabets. It is sometimes inappropriately referred to as International Phonetic Alphabet, which is actually the official name of an alphabet used in linguistics created in the late nineteenth century.

The NATO phonetic alphabet is now widely used in business and telecommunications in Europe and North America, and has been approved by ICAO for use in international civil aviation. It has been adopted by the ITU, (many radio operators will refer to the NATO phonetics as ITU phonetics). Although it consists of English words, its letter codewords can easily be recognized by speakers of languages other than English.

The NATO phonetic alphabet is generally understood by Amateurs in all countries. Used when giving your callsign or passing information that must be spelled out for clarity. For example, AC6V should sign ALPHA CHARLIE SIX VICTOR

Funny Phonetics which are memorable and easy to recall - like Karl # Always Killing Time. W # Empty Alcohol Jugs. Wrong phonetics but very very common on VHF repeaters and HF Contests. Kilowatt # Blue Oyster.
W # Big Kilowatt !!!

WWII Phonetics: Some old timers insist on the WWII phonetics: Able Baker Charlie Dog Easy Fox George How Item Jig King Love Mike Nan Oboe Peter Queen Roger Sugar Tare Uncle Victor William X-ray Yoke Zebra. And these guys are always tuning after a CQ Call !!

Civil Entity Phonetics. Some hams use the police/fire phonetics but many don't use or understand these: Adam Boy Charlie David Edward Frank George Henry Ida John King Lincoln Mary Nora Ocean Peter Queen Robert Sam Tom Union Victor William X-ray Young Zebra
And a lot of other Boy/Girl names depending on locale

Make Em Up Phonetics: Then we have Hams who don't know any of these and you might hear
Name is Tim - Texaco Indigo Macy's Actually heard this one!
