Off to Asia for the Week

Jul 30

Posted by mikelee in Uncategorized | No Comments

Hi all,

I am off to Asia for the next week, but we’ve put a number of articles on the blog for distribution during all of next week (almost every day, as usual). Going to Singapore to do a progress check on a project I have there with the national airline, as well as Manila for the major telephone company in the country. Will be back on Sunday the 8th. If you guys have any questions or concerns, feel free to contact Doug or Phil – they should be able to help you with virtually anything that I would have done while here. I will have my DVAP with me, so don’t be surprised to hear me on D-STAR from Singapore or Manila. I’ll also have my computer, so D-STAR registrations will get approved in a timely, albeit slightly delayed manner.

In the meantime, you can expect a number of things to happen in the week that I’m gone:

  1. The JAX Beach D-Star system should be operational – frequency will be on 444.975+ and the call sign will be KJ4RYI-B. Those of you who have been using the Daytona Beach UHF D-Star system will recognize that the frequency is the same – and for good reason – there is no other repeater on the air within better than 50 miles with that frequency pair. Steve Finger (KB4DNQ) is the “ring-leader” for the install there – and it is using the Satoshi Hotspot in Full-Duplex Mode, along with an internet connection for connection to other repeaters and reflectors. We’ll probably have this connected to REF034C most of the time, so that JAX folks can have direct conversations via the gateway to St. Johns, Flager and Volusia users. Steve already has the HotSpot and the two radios, and I have tuned-up a UHF repeater duplexer and assembled the interfacing cables so that the installation should be very straightforward. We received the Rack-shelves that we ordered (4 of them) to be able to mount hotspot repeater radios, as well as Gateway computers as necessary.
  2. The antenna installation for “Big JAX” should be happening while I’m overseas – this will be a DB-224E antenna that will be positioned at about 500-ft on the 1,000 foot tower. Coordinations are already in place – and this repeater call sign will be KJ4RYG-C. Electronics will not be installed while I’m gone, but we will prep the most difficult parts – the antenna and feed-line. Eddie, Phil and Doug have access to my storage facility where we have the 900+ foot spool of VXL7 Heliax hardline (1-5/8″), as well as the connectors, cable hangers and the antenna, so my attendance at the antenna party is completely un-necessary.
  3. Progress on MS-150 planning continues under the expert guidance of folks like Doug (N4FPS), Robbie (KG4HUF), Pete (KC1SS), Frank (KB4T), Rick (KC2HFL) and Phil (K5BBC), with Eddie’s (KJ4LRB) continual support on the admin side of the house. I know that they are planning for the first Group Exercise – scheduled for August-21. Please reserve the date, if you haven’t already. Also reserve September 18th and pencil-in September 11 as a possible table-top exercise.

MS-150 Net Control Antenna Configuration

Jul 28

Posted by mikelee in ARES Events | No Comments

We recently tested the proposed antenna configuration for the Net Control Station which will likely be at Beverly Beach (although this test was performed at Palm Coast). The objective of this test was to determine if two, close-spaced antennas would interfere with each other while having simultaneous transmit/receive stations on 147.15+ to the South, and 145.21- to the North. There were numerous speculations about whether it would succeed or fail – so a real-life test was in order.

The test was performed in the parking lot of the Rymfire High School (Rymfire and Royal Palms, in Palm Coast) at about 10:30 on Sunday. Participating were Eddie (KJ4LRB), Charlie (AA5QJ) and myself (WB6RTH).

Using already available antennas (not new purchase), we were able to achieve the following:

  • North pointing antenna aimed in the general direction of St. Augustine for the 145.21 (primary) and 146.625 (backup) repeaters. Antenna was a Cushcraft A27010S Dual Band Yagi with 5 elements each on VHF and UHF.. Radio was an Icom 2820 running full-power at 50w on VHF.
  • South pointing antenna, aimed at Daytona Beach / Holly Hill for the 147.15 (primary) and 147.375 (backup) repeaters. Antenna was a Japanese 3-element VHF Yagi which is portable with claimed gain of 6dbi and f/b ratio of about 18db. Radio was an Icom 2820 running full-power at 50w on VHF.
  • The configuration was as follows: North facing antenna (the Cushcraft) was at about 6-feet on a heavy-duty tripod. The South facing antenna almost even, facing 180 from the Cushcraft.. The mast and tripod had to be stabilized (by hand, in this case – but with guy ropes during the event).

Pictures below – the configuration is TOP HEAVY due to the size and weight of the longer Cushcraft. But we needed it on the top, since the path from Palm Coast to St. Augustine is both longer and lined with dense trees along the way.

Above: Charlie (AA5QJ) posing with the Antennas
Charlie did all the tuning of the Gamma-match, while
Mike watched the analyzer and sounded the VSWR.


Above:  Charlie (AA5QJ) adjusting the antenna.
Cushcraft is pointing to the RIGHT, and the Japanese
collapsable, portable 3-element YAGI to the LEFT.

Picture HERE

How was performance..??

  • Transmitting on 145.21 to St. Augustine, there was NO desense or S-meter reading on the other radio (tuned to 147.15).
  • Transmitting on 147.15 to Daytona, there was no desense or S-meter indication on 145.21.
  • Transmitting simultaneously, both radios were able to talk “cleanly” into their respective repeaters. No intermod (that was observable or objectionable).

Overall, this looks like a workable configuration. More testing in the field trials might reveal problems or issues, but this looks like it will work.

MS-150 Net Control Location Selected

Jul 27

Posted by mikelee in ARES Events | No Comments

We’ve tentatively selected a location on A1A in Beverly Beach for the location of the Net Contol operators. We will have at least 3 operators there  at all times during the event – 2 On-Duty Net Controls + 1 “Supervisor” who will be keeping an eye on the “big picture” and at least 1 relief operator. The intent is to have all operators trained to assume any position at that location as needs arise.

The selected location is at the Beverly Beach Campground – on the WEST side of A1A – this keeps us out of the line of heavy traffic for the campground, yet gives us a clear view of A1A on it’s north-south alignment. There is Power, Water and Sewer at the location, so we will have all the facilities needed to make a comfortable operating location under the awning from a large motorcoach. EMCOMM-1 will be there for the operators and will will have plenty of space to erect antennas, if lateral separation is required.

The current plan is to use two YAGI antennas for 2-meters – one facing north toward the St. Augustine repeater(s) and another facing south toward the repeaters in Daytona Beach and Holly Hill. Our initial tests indicate that we should have no interference problems with both stations transmitting at the same time, or dsense from one into the other.

Assembly of the DV Adapter – VIDEO

Jul 26

Posted by mikelee in D-Star Users, DSTAR Projects | No Comments

We have been fortunate to receive a live training video made for us of the construction process for the DV Adapters from Peter (AI4UE). We have two of these units  - one was built on Saturday while Peter recorded the build-process. For those of you who would contemplate building one of these kits int he future, this video will be valuable. It’s over 1-hour, 40-minutes long – almost the time that it takes to construct the entire board (figure on 2-1/2 hours for us first-timers).

Peter is the US Distributer and expert on the DV-Adapter which allows you to run D-Star on the HF Bands. Given our interest in the technology, he has made special “accommodations” for us – this video, special one-on-one assistance and helping us to get this off the ground in North East Florida.

View the video here:  DV-Adapter Construction Video

If you would like copy of the Flash Video (FLV-file), please email me and I’ll send you a link to download a copy. This is for your personal viewing only – all material copyright AI4UE.

Depiction a Geospacial Tool for Emergency Mgmt Part II

Jul 25

Posted by N4FPS in ARES Events | No Comments

Partial Depiction of MS-150 Bike Event

A few weeks ago Mike, WB6RTH wrote a blog about Depiction software stating that Eddie, KJ4LRB and myself (Doug ,N4FPS) were using the software to develop a resource list for East Coast and Crown District ARES.  I wanted to give you a short update on the progress as well as other projects we have been working with using the software.

First let me just say that this software should be in the tool chest of every EmComm group. This software is as useful to our execution as the Radios we use. Depiction software is a one stop shop for the planning, deployment and execution of any event or exercise. In a single Depiction a full graphical plan can be developed to take care of every aspect of an event or exercise. Image having the whole event displayed before your eyes on a single screen including the planning, deployment and execution. Your screen changes and updates as elements of the event change and resources are moved or advance. With a single screen, Operators can track others along a Depiction drawn route in real time while monitoring live weather conditions and sending and receiving live reports from one another including updating each others Depiction screens from remote locations. Visualize a roving operator calls in a location of a unforeseen emergency that blocks a route needed for delivery of supplies during the recovery operation of a storm or a route on a bike event.  Net Control places this road block in Depiction and the software re-routes the previous route and displays graphical and written instructions of the new route.

Depiction can be a vast database for your group’s members and resources. A single click on an icon representing a location will reveal the assigned operators and their personal information and the equipment available at that location. Depiction uses information available free from the public domain to display such things as weather radar, elevation data and a multitude of maps including, roadmaps, topographical and aerial maps. The depictions that you build can be placed over any of these maps at a single click.  Depiction will read and display GIS data that is  available publicly on the internet for States and Counties including locations of EOC’s, schools, shelters, police and fire stations.  You can display tower site locations and even get Depiction to draw line of site data for a given antenna on that tower.  One of my favorite capabilities is the ability to display a graphical representation of flooding based on user defined information.

We are using Depiction to help develop our event plan for the upcoming MS-150 bike event. We have also been working on building Depictions of the local ARES resources that can be imported into any future Depictions for events or activations.

I for one will use Depiction in all future planning for ARES events as well as for many personal events around home.  Depiction is great for planning your personal emergency plans at home.  I will begin using this software at my paid job as well.  One of the things that I do at work is write plans to conduct prescribed burning.  With depiction I can actually Geo-code my own maps into Depiction of the area I want to burn including the placement of fire lines and fire equipment and resources.  The cool part is I can enter an element to predict the smoke plume to meet my requirement of developing a smoke management plan which is a requirement of any burn plan.
