An HF band, 28.000 - 29.700 MHz Region 1 (Including UK). The highest and one of the largest of the HF bands. This band can be both interesting and frusrating to operate on, relying heavily on solar conditions to determine how far a station you can work. Primarily a daytime band, 10 meters will come alive during high solar periods not long after sunrise, and often remain useable until after sunset. The 10 meter band is often polluted by people illegally freebanding with modified CB rigs, which can make contact and intelligent conversation difficult.
