Well, there are hand held radio communication devices for just about every band now. 27MHz CB now have handhelds with 40ch. AM and 40ch. AM/SSB. There are UHF CB handhelds that have full 40 chnnel coverage and some with the first 16 channels only. There are also 55MHz hand held available unit and some on 433MHz.

More recently though some new handhelds have come out in the 433MHz frequency range which lies in the Amateur Radio Band. These hand helds are very low power and operate on FM. I haven't used one myself, but imagine they would operate quite well. The only draw back is the unfortunate case where one of the 20 channels lie right on repeater inputs in the 70cm amateur band, and you happen to operate on this device within range of a repeater or similiar.

	Mundara SY-201 An AM and SSB handheld CB. The SY-201 provides full 40-channel operation, LCD display, Mic gain and RF gain controls and selectable high-low output power. It can be used in a vehicle with the supplied slide-on adaptor. Handheld operation uses optional "AA"-sized batteries, providing up to 6W PEP RF output.
	Uniden UH-040XR 500mW output power. It has an LCD display, duplex capability, auto squelch control, auto power save and battery level indicator.
	Uniden UH-045 I have actually purchased a Uniden UH-045xr. It has been used for mostly car to car communications and does the job well enough, however, when you start picking up some distance you can lose signal of course. The CTCSS feature is quite handy, but it's unlikely that it would be needed a lot. Some features: 19 Channels: Only the first 19 channels of the UHF CB band are included, in simplex only Time out timer: programmable transmission time limit Busy Channel lockout: You can optionally prevent transmission while receiving incoming signals Power Save: The radio will power off until an incoming signal is received CTCSS: 38 CTCSS Codes that will assist in blocking out unwanted noise/signals Output Power: 400mW output only. Power supply: Standard alkaline batteries can be used, or rechargables (requires 4 AAA batteries)

	Digitor D 109920 Channel UHF Transceiver on its on 433MHz segment. 20mW RF output only for up to 1km line of sight use. This also includes CTCSS.
	Digitor D 1095 55.050MHz low power 300m range unit.
	Digitor D 1097 3 channel 55MHz low power 300m range unit.
	Radio Shack TRC 501 55.050MHz low power unit. It gives approx 400m range with decent line of site. Personally, I have used these before and foune them quite good for short range communications - very clear.
	Radio Shack TRC 502 5 channel 55MHz low power unit. This is basically a head set version of the above hand held, but has more channels. It also has the option of voice activated mic.
