The FCC rules and regulations give us the official word on band use. But
there's more to the story. By general agreement, and some prodding by various
organizations, the band has been divided into a maze of allocations and sub
bands. See above illustration. Knowing and following these voluntary
assignments can make you a more efficient and courteous operator. More than
that, knowing what's there and where to find it, can only add to your

These beacons generally run with very low power (some less than a Watt!) and
you can often hear them when the rest of the band sounds dead. Perhaps this

Having been inspired by low-power beacons, you should go QRP and tune around
the 28.040 or 28.060 Mhz calling frequencies for low power operations. Be
By comparison, a Novice or Technician can be a real powerhouse on 10 CW with
ample opportunity for exciting DX. Just take note of the two popular packet
frequencies in this area.

Most packet activity on 10 meters is centered around two frequencies. Check
RTTY and AMTOR enthusiasts should look at the region of 28.090 to 28.100 Mhz.

Depending on your point of view, Novice Enhancement is either something
unmentionable or a real boon for the hobby. Whatever you think, a quick scan
across the Novice/Technician SSB portion of the band when 10 meter is open is
a real eye-opener. An influx of economical new radios and a wave of the FCC's

While there isn't a real standard yet, 28.400 Mhz is a good gathering place
for mobiles to pick up QSOs. If the frequency starts getting busy, move your

you should try again. On 10 meters, any station can catch a rare one by using
courtesy and persistence, even low power mobiles! Listen to what's happening
and try to figure out what catches the DX station's ears.

The middle of the General phone band is home to some big time rag-chewing-try
calling around 28.600 Mhz. Look for SSTV activity between 28.675 and 28.685
Mhz, or on 28.945, if you're into FAX. Another interesting feature is the
continuous code practice transmission at 28.888 Mhz which comes from W6IRT's
QTH (N. Hollywood, CA) running only 5 watts into a ground plane antenna.
AM operation has a frontier outpost between 29.000 and 29.200 Mhz, with

To the newcomer, both rugby and 10 FM seem uncivilized with few survivors.
Well, maybe that's true about rugby, but 10 FM can have a more dignified
manner. Occasionally referred to as the Channel 19 of amateur radio, the FM

you might be surprised by the "no holds barred" activity.
connected to VHF and UHF repeater systems. Some of these operate exclusively
on this channel. Rarely out of control, but sometimes innocently left on, 
they faithfully retransmit the activity of their parent repeater. Users of
these links should take extra caution to ensure their proper operation, and
configure them without courtesy tones or hang time. A properly operated link
can be exciting for repeater users. Link owners should add to that excitement
With such heavy congestion on the calling frequency, stations need to move 
off quickly and continue their QSO elsewhere. The best place to QSY is 29.200

Repeater operation on 10 meters is nothing like its VHF or UHF counterpart.
Frequent propagation over large areas, and only four available repeater pairs
, often result in many repeaters being heard on the same frequency. Use your
best judgment to avoid keying up repeaters which may interfere with ongoing
QSOs. I think in the future we will see some solutions, perhaps PL. In the
meantime, keep up with 10 meter repeater activity by joining the Ann Arbor 10
meter Repeater Net on 29.54/64, Monday evenings at 0000 UTC.

Downlinks located between 28.300 and 28.500 Mhz are paired with uplinks on
other bands. Since satellite operators are'nt transmitting on 10 meters, they
often can't tell you that your're interfering with them. Even though RS-10/11
use 10 meters. Listen around 29.358 Mhz for the RS beacon and telemetry. When
you hear it, tune up toward 28.400 Mhz for the downlink passband.

Ten meters is frequented by a number of contests and regular nets. The
familiar sound of "CQ TEN TEN" is the result of Ten-Ten International, which
currently conducts a daily net on 28.800 Mhz at 1800 UTC. They sponsor
numerous awards and in the process have helped keep the 10 meter band active
nexpensive radios, relatively small antennas, excellent propagation, and a
understanding of the voluntary band plan make it work. Now that you know
