JOTA SATURDAY OCT 19, 8AM at Camp Lazarus

We will be setting up a JOTA station at Camp Lazarus by the dining hall again this year. I will be at Camp Lazarus 8 -8:30am to setup the JOTA Station Saturday morning. We will operate until around 5 or 6pm, when the Monster Mash activities begin.  Please let me know if you can join us to help out with the JOTA station. 


There will be a lot of cub scouts at the camp accompanied with adult leaders/parents. It is a great opportunity to promote the hobby to younger kids and adults. Activities that are planned are as follows:


I have a board put together that has information about amateur radio Satellites and the space station. It also has information about HF signal propagation and 2 laminated maps, one of the US and one of the world. Scouts can mark the locations on the maps of the stations they talked to with a dry erase marker. Another tentative activity I am also working on is a scavenger hunt/Questions/answers sheet that the scouts can work on while they are waiting. Some answers will be on the board, some may require the scouts to ask an amateur radio operator.  


2 CW practice Oscillators - scouts can practice sending their name in CW while they are waiting to talk on a radio.


Fox Hunt - Find the hidden 2 m transmitter. A transmitter or two will be hidden and the scouts can try to find them using a tape measure beam antenna and a HT.


HF Radio - there will be a HF radio setup with a 80 meter dipole fed with ladderline with a tuner to get scouts on the air talking with other scouts. It will tune on multiple bands.


DMR - there will be a DMR radio there to use with the Delaware DMR repeater. If you want to bring your own DMR radio you can. The JOTA Calling TG will be setup as static on timeslot 1, Time slot 2 will be used for dynamic (Push to talk activated) JOTA TAC talkgroups. See the attached image for the JOTA talkgroup numbers


TS1 JOTA CALL 907 (static)

TS2 JOTA TAC 1 - 8 (Dynamic)
