2018 Military Cross-Band test info

#1
If your thinking about getting into Ham radio or setting up comms for your local group or any "other reason" this is a good place to ply your ability. All times an dates are UTC (aka) ZULU. The listed freq's are where the MARS station are transmitting only, once you hear them they will indicated where they are listening, so you will have to transmit on that freq an set your gear for working splits. If you are only going to listen unless you have a SWR that allows freq,lock splits you will only hear 1/2 of the conversations. There will be no codes used, everything will be in plain English. The Sec of Def message will be sent via Digital messaging, that info is not posted here but it's on ARRL.org, the ARMY MARS web site as well as many others if you plan on trying to copy it Via open CW (Morris Code) Love the fact they have added BB61 (USS Iowa) this year. the more history ships the better I like it. FYI LST 325 (NWVC) made the landing on on Normandy.

ANNUAL ARMED FORCES DAY CROSSBAND TEST

(12 May 2018)
The Military Auxiliary Radio System will host this year’s Armed Forces Day Crossband Test,
scheduled for May 12, 2018. This annual event is open to all radio operators, and will not impact
any public or private communications. For more than 50 years, military and amateur stations have
taken part in this event, which is only an exercise scenario, designed to include hobbyist and
government radio operators alike.

The AFD Crossband Test is a unique opportunity to test two-way communications between military
communicators and radio stations in the Amateur Radio Service (ARS), as authorized in 47 CFR
97.111. These tests provide opportunities and challenges for radio operators to demonstrate
individual technical skills in a tightly-controlled exercise scenario that does not impact any
public or private communications.

Military stations will transmit on selected military frequencies and will announce the specific ARS
frequencies monitored. All times are ZULU (Z), and all frequencies are Upper Side Band (USB) unless
otherwise noted. The frequencies used for the test will not impact any public or private
communications, and will not stray outside the confines of the exercise.

The following stations will be making two way radiotelephone contacts with stations in the ARS
between the time periods listed on the frequencies listed in Kilohertz below.

I'm about ready, I have my mobile rig, but antenna setup is my limiting factor. Hopefully band conditions will be favorable that day.

Hopefully I'll be able to hit WUG2, AAC, AMF,. I would like to get to the Midway as my grandfather was on it. I'm from socal and have gone on the tour a couple times. They still use the original HF radios in there.

They still use the original HF radios in there.
Most all the ships radios back then only operated on AM. The radios that will be used during the test are mostly ham rigs. Depending the ship an what else is going on her test day, they will either use dipoles, fans or inverted Vee's. I an others would like to see them use the ships radio shack an antennas as there are a lot of Ham operators that could still reach them on a AM emission w/o issue. We (hams) are not allowed the transmitting power MARS is but good antennas can trump power levels (to a point) w/o issue. Interesting to know today's HAM gear plus an average antenna, would surpass most all transmitters during WW II an Korea both. An some things we can do today was only a pipe dream back then.

For your Mobile antenna, just find a hill top an throw up a dipole or inverted Vee in a tall tree. If your only running 100watts or under some 8X coax to your mobile transceiver will get you most places. If you build the antenna correctly you will not need a choke or Balun at all.

I keep many different antennas on my truck at all times, but I find my self using tuned Ham stick Dipoles the most. I've a bracket on the back of the truck that holds the fiberglass military poles. With this set up I can get the array up to about 40-50' most of the time if I have to. For most NVIS work though I set it at 20' an need no guying at all but, higher I have to guy it off as it get to swaying in the wind.

I think a couple of the guys in the local club are planning on going up to one of the hills where one of the local repeaters is and stringing up a temp antenna for this. Hopefully next year I'll be a bit more prepared, building the new house has me pretty tied up.

Myself, after passing the test last year, I had totally planned on being 'further along' than what we are now. We even traveled across the province to pick up a mast last summer.

Alas, considering what-all is going on (as explained in a thread in the 'Pit) I don't know when I'll be able to pursue this further, and am looking at selling the mast. What I want, NO. Is it responsible, yeah.....

Dammit.

As per the MIL Cross-Band test, get 'out there' Guns, and contact away. If you get a chance, say hi to BB61 for me. I've always admired that Iowa Class.

Well tomorrow at 0700 local it kicks off. Hoping the bands are better than they have been the last 3 days, as Mr. sun has not been kind these last few weeks/years. Talked to A1AW (ARRL) this afternoon, an it was so bad I only about a 80-85% copy on my end but they had me at a 5/7. If it's this bad tomorrow I for see the amps, getting a heavy work out all day long.

Well it's in the books now. I missed 6 stations total as I could not hear them at all. However 4 stations had the same transmit freqs which did not help at all. Some of the stations I did get required some skills to find them, as they were either on the wrong freq or were using the wrong emission mode.
My missed stations were
USNS Mercy
ADB Japan
ABM1 "
ABH Hi.
AIR US
AAC US

Some stations I made contact with twice on different freq's, one of them (MARSRADIO on 14,606.00) amassed both of us as we should have been way to close to recieve each other, (me Al Him Ar)but I'm guessing both of our antennas were perfect for the conditions on 20 meters.

Nice! I got redirected yesterday and never got to the radio. Making all but six is nice! Hopefully next year I'll have my stuff lined up.

I was looking for all but one, ABH has always eluded me for some reason. Although at one point I thought I heard them very faintly on 17 meters. Next year I will have a 1400-1500 foot listening (RX) only antenna up as the TS2000 I use has that ability. I wanted it up an working before this one but, too many other things got in the way, like shooting, trucks, woman, an such. Next year it will, be ,up! Some of the stations do not run power, but if you can't hear them, your sure not going to work them. With my Beam an up to 1500 watts + on standby I've never heard a station I could not work, to date. But I have to hear them first, so it's time for me to get off my ass an get the RX antenna up.
