Single Sideband on 2 Meters: The Other VHF Mode

Most new hams get started on the ham bands using FM, with 2m and 70cm being the most popular bands. This is a great way to get started using VHF simplex and repeater communications. 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.)

As an example of what is possible on SSB, during one VHF contest I was operating portable 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 2m 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. SSB operation is not channelized like FM simplex and repeater operations, so you’ll need to tune around to find other stations on the band. A station may be operating anywhere in the SSB sub band, and not one any specifically designated frequency or channel. As a result, and as compared with FM, adjusting the transceiver frequency is much more critical. If you are not precisely aligned on the same frequency as the station you are listening to, the audio will sound odd. Fine tuning adjustments will be needed to get the audio tone of the received station just right.

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, as 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.

VHF Nets You will need to check around to see if there is a SSB VHF Net in your area. Find out what time it is held and the frequency of operation. Checking into the net is a great way to try out SSB and to make contact with the 2m SSB operators in your area.

VHF Contests Think of VHF contests as “VHF activity weekend” since they are a great opportunity to just get on the air and work 2M SSB enthusiasts. The main contests are the ARRL June VHF Contest, the ARRL January VHF Sweepstakes, the ARRL September VHF Contest and the CQ Worldwide VHF Contest in July. For more information, take a look at this article from my personal ham radio blog: How to Work a VHF Contest.

Various transceivers supporting VHF SSB.
Transceivers offering SSB mode on VHF/UHF bands include the Kenwood TS2000, Yaesu FT-897D, and Icom IC-9100, as well as many others.

Equipment The required equipment for getting started on 2M SSB is pretty basic – a transceiver capable of 2M SSB and a 2M antenna. 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.

M2 Antenna Systems 2-meter HO Loop is a horizontally polarized omnidirectional antenna.

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 you 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 a new operator on 2m sideband.

Hi Bob,

I have found that a 2 meter dipole is extremely effective in sending and receiving signals on SSB. Easy to make and you will be thrilled with the results!

Never talked 2 meter sideband. Tomorrow im getting a Yaesu old school rig and matching desk mic. Will work on a horizontal antenna later.

Hello! Love the article. I’m an old HF SSB salt and would love to find a handheld SSB 2m rig. Were these ever made or can you suggest one to search for used? Thanks OM!
