Land Ops - The Off Road, Navigation and Amateur Radio Search Club
The Northern California chapter has been invited to do a concurrent Landops event during the SAR Death Valley Advanced event scheduled for 26 September 2015.
I would like to open this forum on posting up ideas on how we would run a concurrent event somewhere in NorCal such that the event occurs simultaneously to the listed SoCal event.
The idea here is to link the Ops such that training and communications between the two groups is beneficial to the participating members.
Post up your ideas below.
Note: We have demonstrated the ability to communicate between landops teams located within a 200 mile radius of each other via 40 meters in daytime using specialized NVIS inverted "vee" antennas.
1. The only tried and true method for communicating over such long distances is 40-meter with NVIS antennas.
Here are some other possibilities, but each has some disadvantages:
2. APRS text messaging. The problem is that we probably won't find an internet connected digipeater in Death Valley
3. IRLP or Echolink repeaters. The problem is that there are no ham repeaters in Death Valley.
4. Amateur radio satellite communications. The problem is that amateur radio satellites have a communications window with ground stations of about five minutes during each orbit so the timing for the teams to establish contact via the ham radio satellites could cause a team to wait a long time for the satellite to pass.
