Crossband Repeater

“A vehicle with a locked-band repeater parked in a moderately favorable location provides near county-wide coverage. ” Bryan KG4UPR
Requirement: true dual-band mobile radio as opposed to dual VFO)
Recommend:  learn how to set up your true dual-band mobile radio for locked-band repeater mode.  Store the configuration in a Programmable Memory for ready access. Test it regularly.
Mobile Radio Configuration: Locked-band repeating for emergency use would typically have the mobile radio set to receive on an appropriate UHF frequency (e.g., 440.850 MHz simplex), and set to transmit on an appropriate VHF frequency (e.g., 147.480 MHz simplex). The UHF input (receive) should have Continuous Tone-Coded Squelch System (CTCSS) enabled.
HT Configuration: A dual VFO HT configured to use the locked-band repeater would have its transmit VFO set to the the UHF input frequency (with output tone configured to match the locked-band repeater CTCSS), and likewise its receive VFO would be set to the VHF frequency of interest. Typically the HT is going to be in close proximity to the locked-band repeater, so the HT should be set for the minimum power level necessary (e.g., 0.5 W). It’s possible with some radios to remotely adjust the operating configuration of the locked-band repeater using DTMF tone strings.

In Virginia, ARES® = RACES

ARRL – 07/24/2008On July 3, Virginia officials, along with representatives from that state’s ARES® and RACES groups, signed a new Memorandum of Understanding (MOU), uniting the three groups. State Coordinator, Commonwealth of Virginia Department of Emergency Management (VDEM) Michael M. Cline; State RACES Officer Mac McNeer, K4YEF; ARRL Virginia Section Manager Carl Clements, W4CAC, and ARRL Virginia Section Emergency Coordinator Ron Sokol, K4KHZ, signed what ARRL Emergency and Preparedness Manager Dennis Dura, K2DCD, called a “precedent setting” document.

“Before the signing of the new MOU, the Commonwealth of Virginia, Virginia’s Department of Emergency Management RACES Program, the ARRL ARES program and various representations from unofficial RACES groups in Virginia led to the ineffective utilization of Amateur Radio resources,” Dura said. “In some situations, Amateur Radio was not even a part of emergency management organization’s response structure due to existing tensions and problems.”

According to Clements, the new MOU spells out that during activations that require deployment of ARES personnel, a State RACES officer at the State Emergency Operations Center will direct the Virginia Section Emergency Coordinator as to where Emergency Communications help is needed. The SEC will then assume the role of Virginia ARES-RACES Deployment Officer and will be responsible for the deployment of all Virginia ARES personnel and resources.

“The MOU formally recognizes any registered Virginia ARES member as a registered RACES member in Virginia; a volunteer does enjoy limited protection from liability to the same extent as a state employee, provided they act within the scope of their training, the limits of the MOU and the mission assigned by the agency,” said Clements.

“This MOU now provides the opportunity for all of the independent RACES units operating within the Commonwealth of Virginia to join with ARES/RACES to complete the fabric of mutual assistance that will help us cooperatively cover the entire Commonwealth,” said Clements. “We will continue to work together with emergency managers across the Commonwealth in support of their emergency communications needs in service to the citizens and guests in Virginia.”

Sokol said he was extremely pleased that the signing of the document has come to fruition: “The restoration of this MOU has taken a succession of ARES administrations to accomplish. Both Carl and I are pleased to be in leadership at this time to see this MOU to conclusion. We are fortunate to have such viable and flexible VDEM leadership and staff to work with. This document allows ARES/RACES to [work] as one in the best interests of the citizens of the Commonwealth of Virginia.”
