	This part of the amateur spectrum is more prone to radio frequency interference than other parts of the amateur spectrum. Natural noise is high on the band, and mobile use in automobiles often requires careful attention to suppressing stray RF emanations from the vehicle's electrical system. A properly-configured 6 metre mobile station can be very effective.		This part of the amateur spectrum is more prone to radio frequency interference than other parts of the amateur spectrum. Natural noise is high on the band, and mobile use in automobiles often requires careful attention to suppressing stray RF emanations from the vehicle's electrical system. A properly-configured 6 metre mobile station can be very effective.

			Interference from 6 metre stations to broadcast receivers may also be problematic in countries where the band is adjacent in frequency to television signals (such as VHF channel 2, 54-60 MHz in North America NTSC-M). A poorly-designed broadcast receiver may be susceptible to overload due to the presence of a nearby and powerful adjacent-channel signal.

	Most communication paths on 6 metres are line-of-sight. In many ways, the band behaves like other VHF bands.

	Single-band 6 metre gear used to be common, but has largely fallen out of use. However, many modern HF rigs have added 6 metres to the bands supported. Rigs in current product that support all-mode 6 metre operation include the [http://www.eham.net/reviews/detail/109 Alinco DX-70TH], [http://www.eham.net/reviews/detail/63 Icom IC-706 Mk IIG], [http://www.eham.net/reviews/detail/3046 Yaesu FT-857ND], and [http://www.eham.net/reviews/detail/3821 Kenwood TS-480SAT].

The upper 2 MHz of the band is generally used for [[Modes#Frequency-Modulation (FM)\|FM]]. Some areas have 6 metre [[Modes#Frequency Modulation (FM)\|FM]] [[repeater\|repeaters]].

	This part of the amateur spectrum is more prone to radio frequency interference than other parts of the amateur spectrum. Natural noise is high on the band, and mobile use in automobiles often requires careful attention to suppressing stray RF emanations from the vehicle's electrical system. A properly-configured 6 metre mobile station can be very effective.		This part of the amateur spectrum is more prone to radio frequency interference than other parts of the amateur spectrum.
