If you haven't picked up your DIY 150-watt Dummy Load Project from Angelo, you'd better get one now before they are gone.
It takes fewer than 30 minutes to build the kit.  The cost is $ 20.00 with all proceeds going to the Club.

Great job Angelo, K3YUN!

J-pole at 20 feet. I could move it to the top of the tower but I’d like to see more details about the exercise before going to that.

THANK YOU!  It appears we have outstanding participation in this exercise.

We are finalizing the three locations - one in the Port Charlotte / Murdock area and one on the south side of Punta Gorda and the final location will likely be a little east of these locations.
Frequencies will be set for each of the zones in both VHF and UHF.
And we are configuring the portable stations to operate from painters poles or similar portable mast systems.

Stay tuned for details so you can get your hand-helds programmed and ready to go!

Hi Don,
Thanks again for all the useful information. I think I can make it happen as I already have a tilt base from DX installed but got called on it due to HOA rules. I think I can get away with it on a temp install every other Thursday evening...then take it down before AM. I was looking at a comet Antenna unit that is around 7.5 ft in height on top of a twist lock pole That should get the base at about 20 feet.
Talk soon, 73’s

Looked on the map and from my location (Net Control) to your location is about 9.5 miles.  Depending on the elevation of your antenna (how high is it mounted), you could be in the fringe of my reception area or just outside of it.  So, elevation is item #1.

The other thing is power.  What I found very quickly, very early on, you need to go up in power.  I'm operating at 100 watts to be able to reach all that I can reach, and even then, still have to rely on relays to communicate with outlayers.  So, power is item #2.

Obviously, an antenna that is tuned to 6m (without using a tuner) will give you better true power out of the antenna.  I know you said you had a 6m ham stick but it didn't receive as well.  That's probably very understandable.  Again, you are at the very southern edge of my transmission area and most of the folks are north of me, some at the very northern edge of my transmission area.  I have trouble hearing some of them, so you would most likely never hear them.

One thing I am a bit confuse about, You made a comment that Susan was blasting in.  However, I have never had a Susan check in on my net in all the times I ran it, so that leaves me confused.

So, elevation, transmit power, and 6m antenna, as Doug said, I am using the GP-52 mounted on top of a 24 ft painters pole and it gives me pretty good coverage, especially being in an HOA.

If you have any other questions, you can contact me direct at kumpostd  @  hotmail.com (take out spaces)

I forgot to share the most famous local antenna for 6 meters - It's KO4ACY Chuck's Copper J-Pole.
It is mounted in a tilt-over base made up of three 10' pipes (1 1/2" dia).
Ask me about the hose that got stuck during the installation some time - it's a two beer story.

Rod,

Great radios.  I love my 590s and I have had the opportunity to run the 7300 a few times.
Sounds like the antenna(s) are reflecting enough power back to the radio that the radios are folding back and reducing power.

At your location, antenna height is a key factor.  If you can get something up 20 feet or so that should help a lot.  You might want to start with a simple verticle dipole.  They are easy to tune and simple to make.  This is more complicated than the simple wire antenna, but it might give you some inspiration...lol.

Hi Doug,
I’m in Burnt Store Marina using an SX-80 vertical (80-6m) have tried 
my Icom 7300 and Kenwood ts590. Have three manual tuners etc..
None of the tuners are rated for 6 and SWR is to far off for the radio’s internal tuners to handle it. I bought a 6 meter ham stick a month or so ago and couldn’t get it to hear as well as my vertical and it couldn’t be heard either. I don’t have an antenna analyzer so even with the ham stick I don’t know which way to adjust length or counterpoise wire.
Thanks for asking,
Rod  K4BGU

I'm in. I am new in the area, but used to be active in Ares/Races and EOC on the other side. Are you guys utilizing NBEMS here? It would be a good exercise for it. Easy to do with no special equipment and a handheld. Here is some good info, if not.

Charlotte Amateur Radio Society

A Preparation Excercise for an Emergency Radio Communications Drill


This exercise is the first step towards a scenario-based training drill that involves a county-wide simulated emergency.  This simulated emergency includes a loss of regular emergency communications through telephone, cell phones, and internet services.  The drill specifies that radio communications may not utilize any repeater services nor any internet services.


The first phase is to test the capabilities of the hand-held radio and determine their ability to reach a portable VHF/UHF station.  The goals of this exercise are:


  1. Determine the maximum range to complete reliable and effective voice communications of the hand-held radios.

  2. Identify the issues involved in setting up a portable operation for VHF/UHF communications.

  3. Determine the ability of the portable operation to complete reliable communications to a portable command center.

  4. Evaluate the ability of mobile units to augment emergency communications with the portable field centers and the portable command center.


What do we need from the amateur radio community to hold this exercise?


GREEN ZONE - 6 licensed amateur radio operators


  1. One portable operation designated the “GREEN” Station.

    1. Two licensed operators

    2. One dual-band mobile or portable base unit capable of 50 watts on FM

    3. One antenna system with a minimum mast height of 20 feet and a maximum mast height of 25 feet in height.  The antenna can extend above the mast.

    4. All appropriate power, coax, and other support gear including logging supplies.

  2. Four (4) “GREEN” operators with 5-watt hand-held radios

 

BLUE ZONE - 6 licensed amateur radio operators


  1. One portable operation designated the “BLUE” Station.

    1. Two licensed operators

    2. One dual-band mobile or portable base unit capable of 50 watts on FM

    3. One antenna system with a minimum mast height of 20 feet and a maximum mast height of 25 feet in height.  The antenna can extend above the mast.

    4. All appropriate power, coax, and other support gear including logging supplies.

  2. Four (4) “BLUE” operators with 5-watt hand-held radios


RED COMMAND CENTER - 2 licensed amateur radio operators


  1. One portable operation designated the “RED CONTROL” Station.

    1. Two licensed operators

    2. One dual-band mobile or portable base unit capable of 50 watts on FM

    3. One antenna system with a minimum mast height of 20 feet and a maximum mast height of 25 feet in height.  The antenna can extend above the mast.

    4. All appropriate power, coax, and other support gear including logging supplies.


Additional needs - 2 mobile units and one “Big Gun” Base station 


  1. It would be helpful to have two mobile units to participate in the exercise.  We can evaluate the appropriate use of mobile units in an emergency situation.

  2. It would also be nice to have a base station with a tall antenna system to observe and report their findings and thoughts on the exercise.



This is an ambitious excise that requires approximately 14 -17 amateur radio operators to participate in the event.  I suspect we would hold the event on a Saturday morning.  The exercise would begin at 10:00 am and conclude at 12:00 noon.


We have a series of communication tests planned for the event.  We will specify the location of each of the “ZONES” and the frequencies required for operations.  We will test and compare VHF and UHF capabilities.


Let’s see if we can raise enough operators to make the exercise worthwhile.  If so, we can work through the planning issues.  I am guessing we will target mid-November to mid-December for the exercise.


Please post your interest here.
