New Polk County Fire radio system? Could happen if grant is approved

The Des Moines Register reports, albeit vaguely, that the Polk County Sheriff’s Office, on behalf of fire departments served through its communications center, is working on earning a $1 million federal grant to switch out its VHF equipment in favor of 700/800 MHz trunking equipment.

Currently, the Polk County Sheriff’s Office leases airtime on the 700/800 MHz RACOM network, while the Polk County Fire Department (made of rural departments that are dispatched by PCSO) resides on conventional VHF frequencies that are then patched to the RACOM network.

The “Assistance to Firefighters” FEMA grant would allow the county to purchase roughly 116 mobile radios, along with 217 handhelds. A decision on the grant is expected by late May. Polk County would have one year to formalize the purchase and that would allow the county to select a new radio system.

Without the text of the grant application, it is unclear whether Polk County Fire would directly join the RACOM network or create a new standalone interoperable system, although reports surfaced earlier this year of a request for proposals (RFP) for a new, leased countywide P25 fire radio system. Westcom and Des Moines will have the option to join the project.

Ankeny Fire was selected to file the proposal, as Polk County was not allowed to apply for the FEMA grant. If the grant is approved, Ankeny, Polk City, Elkhart, Saylor and Delaware townships, Altoona, Bondurant, Granger, Grimes, Johnston, Mitchellville, Pleasant Hill, Runnells and Windsor Heights would benefit from the grant.


What’s your Field Day station this year?

Operating under the lights overnight at the Jollyboat Shelter at Big Creek State Park near Polk City, Iowa, for the 2009 W0AK Field Day.

Operating under the lights overnight at the Jollyboat Shelter at Big Creek State Park near Polk City, Iowa, for the 2009 W0AK Field Day.

Again this year I will be operating under the callsign W0AK for this year’s DMRAA/ARTS Field Day that will be based at Big Creek State Park near Polk City, Iowa (just outside of Des Moines). I will be mostly operating during the overnight hours, since my girlfriend will be home from 9-land for the weekend from her clinical rotation… she’s demanding attention even though it’s Field Day weekend! The nerve!

There’s been a lot of shop talk about what equipment everyone will be using and what class. W0AK (along with the GOTA station W0SCI) will be operating Class 2A, Iowa — same as last year. We may not be totally on battery power, since we will have one or two Flex SDR machines that seem to be happier on AC mains.

1 kW Power Shade by PowerFilm Solar

PowerFilm Solar, based just north of us in Ames, is graciously donating a 1 kW military-grade Solar Shade which is basically a large tent with flexible solar panels. I can’t wait to show it off. We’re still deciding on what will be put underneath the Power Shade, our operating area or the welcome area. The solar panels will be used to charge the batteries used for the radios.

Two generators will power the logging PC’s, lights, and the coffee pot. The generators will be a 3 kW EU3000I and a 2 kW EU3000I.

The radios and antennas may consist of (rough plan):

  • Flex SDR
  • Kenwood TS-690SAT
  • Kenwood TS-850
  • Yaesu FT-100
  • Whatever other radios people want to bring out
  • Two masts/rotators/controllers, with 200′ control line
  • Carolina Windom
  • Ladder line
  • G5RV
  • Buddipole (6m)
  • Some random antennas and towers from the NWS station

I feel pretty confident that our club has come up with a very good operating plan. Last year we made just shy of 1,000 QSO’s, and I’m hoping that we can break that number. Looks like the weather in central Iowa will cooperate for Field Day activities, which is a much-needed reprieve from the daily heavy rainfall we’ve been receiving.

If you’re in the Des Moines area, please do come out to our Field Day site to see what the DMRAA is all about. It doesn’t cost a thing, and there will be free food! Operating activities start at 1 p.m. Saturday and goes until 1 p.m. Sunday. We will also be holding a potluck supper on Saturday at about 5 p.m. For a map and directions, visit the W0AK Field Day website.


Video: 2009 W0AK Field Day

At last year’s W0AK Field Day I decided on a whim to produce a short video with only my Nikon Coolpix P3. It mostly focuses on the ambience and atmosphere of the operation aspect of it. This year I think I’m going to do the same, but hopefully catch some of the setup and some time with dignataries that we have invited. The only thing I’m grimacing about for this year’s video is the audio quality. For a point-and-shoot, the P3′s video quality is very decent (YouTube’s converting lost most of the quality though) but the audio is downright crap, so it’ll be difficult to do interviews or sound bites. I wouldn’t mind receiving a loaner 5D Mk III though…
