VHF LADD

VHF LADD (Logging Administration Dispatch), LD (Loading Channels) RR (Resource Road or Road Resource) channels, standardized for trucking, logging and use in remote areas for truck-to-truck, truck-to-base and emergency services communications with trucks, loading channels, etc. These frequencies are known by several names, including the Ice Road Channels, Ice Road Truckers Frequencies, Loading Channels, LD channels LAD channels, LADD channels, Resource Road channels, Logging common channels, Natural Resource Road Channels Resource Road VHF, VHF trucking channels, Canadian trucking channels and several other combinations of these. In remote areas of Canada, specific sections of roads are assigned specific channels.

Note that use of 27 MHz CB radio equipment (called the General Radio Service in Canada - not to be confused with the General Mobile Radio Service or GMRS) is still a de facto requirement for trucking and use of CB equipment is strongly recommended.

LADD Loading Channels (LD) and Resource Road (RR) Frequencies Channels Canada Trucking VHF List

Note that the 4 LADD channels are still in regular FM (20 kHz bandwidth or 16K0F3E emission) while the 5 LD (Loading Channels) and 35 RR (Resource Road) channels are narrowband FM (NFM or FMN - 11.25 kHz bandwidth - also known as 11K3F3E emission, 11K2F3E emission or 11K0F3E emission). CTCSS (PL) or DCS (DPL) should not be used on any of these frequencies.

Receivers must be set for carrier squelch or CSQ mode.

LADD and Resource Road VHF radio system base stations can range from 50 watts to 300 watts and may be remotely operated via landline telephone or VoIP technology. Mobile radios with transmit power ranging from 25 watts to 110 watts are used, with 45 watt, 50 watt and 60 watt mobiles commonly found in trucks.

1/4 wave NMO antennas are often used when space consideration and rugged heavy duty antennas are needed but 1/2 wave and 5/8 wave VHF antennas are also used for improved gain on the VHF frequencies. Portable radios are also used for flagmen, wide load safety and other purposes on these frequencies.

While these frequencies were originally intended only for use by logging companies, oil exploration and drilling equipment delivery companies, remote base station dispatch (think 'Ice Road Truckers') and other specialized use, the proliferation of inexpensive VHF-FM mobile radio equipment (including, but not limited to, the Icom IC-2200, Icom IC-2200H, Icom IC-2300, Icom IC-2300H, Icom IC-V8000, Icom IC-F5021, Icom IC-F5011, Alinco DR-135, Alinco DR-B185HT, AnyTone AT-588, TYT TH-9000D, Kenwood TM-271A, Kenwood TM-281A, Kenwood TK-780 series, Yaesu FT-2980, Yaesu FT-2900, Yaesu FTM-3100R and several others) means their usage has become more widespread and these frequencies have become de facto "interoperability" frequencies in remote areas of Canada. The LADD channels in particular are used by natural resources officers to communicate with logging companies as well as for truck-to-truck, handheld radios for flaggers at loading sites and for other specialized purposes.

The LADD and RR frequencies are used as an adjunct to 26 MHz/27 MHz CB radio (called the General Radio Service in Canada - same frequencies and modes as the USA) in some places, and in others, CB radio is used as an adjunct to the VHF LADD and VHF RR and LD channels. Note that the similar MURS VHF CB frequencies are not permitted in Canada for these purposes. VHF LADD does not replace regular CB. Trucks should still retain regular 40 channel 27 MHz AM CB radios in addition to a VHF radio with LADD/LD/RR channels programmed into memory.

Like the Business/Industrial Radio Service (land mobile radio, LMR, PLMR, business radio) and the MURS service, these frequencies are sometimes used for other purposes, such as hunting or other communications in remote areas of Canada and Alaska.
