Std Repeater Offset either +6 or -6 MHz

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.

Std Repeater Offset - 5MHz

Some areas of the country use + 5 MHz offset while others use - 5 MHz.
The 70 cm band is BIG…providing 30 MHz of spectrum compared to only 4 MHz on 2 Meters.
SSB is the preferred voice mode for so-called “weak signal” operators. The mode is more efficient than FM when signals are weak, so it is the way to go when you are trying to push the limits of 70 cm DX.
The channel spacing needs to be at least as wide as the bandwidth of the signal, which allows room for each signal without interfering with the adjacent channel. The vast majority of the country uses 25-KHz spacing for FM repeater and simplex channels. Some areas, most notably parts of California, have chosen to use a 20-kHz channel spacing.

Simplex

Choosing an appropriate simplex frequency can be a little tricky, since local practice varies. Across all of North America, 446.000 MHz is the National Simplex Frequency (also referred to as the calling frequency). In most places, the channels immediately adjacent to 446.000 MHz are used as simplex frequencies, spaced by 25 kHz. This means that 445.925, 445.950, 445.975, 446.025, 446.050, 446.075 MHz are all valid simplex frequencies. But other areas have assigned these frequencies to repeater operation.

Technician

Technician Class License:Technician class license holders have operating privileges on the 10-meter band from 28.000 MHz to 28.500 MHz

General

General class license holders have expanded operating privileges on the 10-meter band, with access to the full band from 28.000 MHz to 29.700 MHz. They have the same operating mode privileges as Technician class license holders, but with a higher power limit of 1500 watts PEP.
JT65 and JT9 digital modes may require up to 1500 watts of power for reliable operation, which is only allowed for Extra class license holders.

Range

Under normal conditions, the 10-meter band can typically support communications over distances o several hundred miles (or kilometers) using SSB voice or digital modes such as RTTY or PSK31. With good propagation conditions, such as during peak solar activity periods or during Sporadic E propagation events, communication distances of over a thousand miles (or kilometers) can be achieved on the 10-meter band.
