Polar Bear on Hontoon Island

Look out Hontoon Island the Polar Bear of Florida is coming your way! Good Friday, 2 April 2010 Polar Bear QRP member #173 (aka K4UPG) will attempt to qualify Hontoon Island as a US Island on the Air by making 25 contacts including at least 2 DXCC entities.

Hontoon Island is a beautiful place for some QRP Portable Ops

Activity will start about 1400Z after the ferry ride over to the island. Plan is to use special callsign K4T for recognition.

Look for us on 30m cw (10.106-10.116 MHz) and 20m cw 14.050-14.070 MHz and on the hour we will check 15m 21.060-21.070. If anyone shows up to assist, will also attempt ssb on 14.250-14.260 MHz island corridor. All ops will be QRP so we’ll need your help to pull us out!

Fishing is good!

If things go well, our Central Florida QRP group may consider this as a new operating site! If you are in the area, come on and check it out with us.

Closing Time is Dusk

Hontoon Island closes when the sun goes down!

Thanks to Florida State Parks for the fine pictures!

P.S. We did it 4.2.2010!  Over 30 QSO’s update coming! I am TIRED!

Polar Bear Midnight Madness Event Mar 2010

A fitting end to this season of PBMME … Saturday the weather was finally decent here in Orlando and with 80F temperature and lots of sun, I certainly earned my red neck for the season! I set up my portable station near the tall pine trees in our neighborhood park on Lake Fredrica. A few curious neighbors came by to find out what the crazy guy with the wires in the tree was doing!

I am really liking the latest antenna launching combo shown in the photo below. I have been using a slingshot taped to a shelf bracket and equipped with a spincast reel, but have been considering other alternatives. The monofilament fishing line is prone to wind knots and tangles and does not always slip through the branches as well as I’d like. I found an old post by Russ Carpenter, AA7QU, a co-founder of Adventure Radio Society, which described using an archery reel and super slick braided line. Sure is nice to learn from those that have gone before! The bright yellow line is very easy to see though very thin, 3x stronger than monofilament and flies through both air and branches with ease! KEEPER!  Think I will do away with the spincast reel and save it for the grandkids!

Great trees for antenna wire hanging!

If you look closely, you can see the 30m half wave going up to the tree on the left. Nearly vertical for 46 feet and is spooled on a Coleman Camping clothes line and used with a 3 ft counterpoise.

To the right is my 20ft Jackite pole and a W3EDP 84 ft antenna with a 17 ft parallel feed with 3/16 inch PET pipe spacers about every 2.5 ft. it tunes 80-15m with my BLT+ tuner.

The Polar Bear QRP Group is a great bunch of guys… (no yl’s or xyl’s that I’ve heard yet) and our monthly outings are something I look forward to each month. The Yahoo Group is a good source of information and laughs as we swap stories and share our adventures. If you like QRP and portable operation, this is the group to join.

MEN OF ADVENTURE by Dan Caesar NI9Y PB #218

These last two Polar Bear adventure radio sprints in January and February was quite an experience operating QRP (5 watts or less) outside in the snow. I never thought I would never do anything like this in freezing weather. There I was knee deep in snow; with a wind chill around 15 degrees, under an open air shelter at Cobus Creek Park, located in the northwest corner of Elkhart County in January. I was invited by Bob, KB9IVA, who said it would be fun. So I got my portable gear and winter parka and headed out to the site. When I arrived Bob wasn’t there. I got out of the warm car and looked over the snow covered picnic table. The bright sun reflected off the stone on the side of the building helped warm things up a bit.

First one gets the warmest spot!

Then the sun disappeared and it became colder.  The heated outhouse was open so I warmed up for a few minutes.

It was too cold for me to set up outside so I operated in my mobile on 40 meters.  Bob arrived in a snowmobile outfit with a bag full of tools, and his ICOM-703 and MP-1 portable all band vertical antenna.

The antenna would not tune properly so I ran 25 feet of RG-59U coax from my mobile antenna to the picnic table.  Then the portable battery pack ran out of juice.  So I took my emergency car starter battery and hay wired a connection to the ICOM-703 and we were back on the air.  When it’s cold radios and batteries don’t work properly.  Wires become stiff, batteries quickly discharge, and the straight key was difficult to use.  Not to mention your exposed fingers feel frostbitten.  I had forgotten my gloves but you couldn’t send CW with them on anyway.

Cold stiff hands on a very cold key! YIKES!

I was more prepared for the February sprint but didn’t count on blowing snow.  Participating in this sprint was, Bob, WA9S Keith, and Steve KB9ZVJ and I Ni9Y.  Keith arrived late and operated inside his Jeep.  I Made a half-dozen contacts from Utah to Colorado to the East coast with my HB1-A 4 watt transceiver using a 50’ end-fed wire only 27 inches high.  Then the wires snapped off my battery pack.  So we quickly repaired the pack with a new connector and we were back in business again.

Bob had his IC-703.  His headphone band cracked in two in the cold.  Bob’s straight key was almost brittle and hard to use with gloves on.  Steve operated SSB with his Yaesu rig, powered by a riding mower battery, feeding a sloping 20 meter dipole about 5 feet high.

It was getting too cold for me so I packed up and left as the snow began to really come down. Steve saw me packing so he packed up and so did Bob.  Keith stayed behind moving to the picnic table and made more contacts in a small blizzard.  Then Park Ranger paid a surprise visit to find out what in the world was going on.  The ranger was satisfied that we weren’t suspicious characters after Keith explained the situation.  The ranger failed to notice Keith had wrapped his antenna rope around the door handle on women’s entrance to the outhouse. There was no way anyone could open that door.   The ranger probably thought we were a bunch of nuts playing radio in the snow.  It was fun and we probably will do it again next season.  Only next time I will be more prepared for polar bear weather.  Oh yes I forgot to say this was the POLAR BEAR MOONLIGHT MADNESS event.  You can read all about on their website http://www.n3epa.org/Pages/PolarBear.htm.  Polar Bears all over the country and in Europe participated in the madness.  The final polar bear event was held March 20th but I took a pass on that one because all the snow is gone so it wouldn’t be as much fun operating in warm spring weather!!!

The MEN OF ADVENTURE will soon take off again.  Barry, WD4MSM says “QRP To The Field” has just been announced for 2010.   He recalled that we took part in the 2009 version that had as its theme “The Great Depression.”  We operated from the WPA site of Monkey Island in Mishawaka (the bridge to Monkey Island was built by the WPA).

This looks as if it might be an ideal outing for us.  Saturday, April 24, 2010
Spicer Lake Nature Preserve http://www.sjcparks.org/spicer.html
Small picnic shelter available; Trees for antenna support if needed;
Restrooms (heated and immaculate) just steps away; Ample parking for hundreds!
Just minutes from South Bend; Plenty to do for family members and visitors (trails, grills, visitor center, two lakes, etc.); Handicap accessible trails and parking immediately next to the suggested operating position.

You to can join the MEN OF ADVENTURE even if you don’t have a QRP rig.  Just show up to learn about portable operation and how to put up antennas where they don’t belong.  Who knows maybe you to will be just as nuts as the other members of the group are?  Present company accepted.

That’s it for this edition.

p.s. Consider operating the special event KØS Strange Antenna Challenge Special Event — May 29-31, 2010.
Start Date & Time: Saturday, May 29, 2010, 1000Z
End Date & Time: Monday, May 31, 2010 at midnight (local time zones)
This is not a serious event.   We are all out here for fun!  K0S will employ out-of-the-ordinary antennas to promote Amateur Radio and making do with what might be available during an emergency.  Individuals and clubs may participate as “satellite stations” by using anything but wire or pipe for a radiating element and adding “/K0S” to their call signs. Details are on the KØS, Strange Antenna Challenge Web site. Strange antennas used in past events, dating back to 2002, have included folding chairs, paint easels, ladders, tape measures, dog kennels, fences, cots and chicken fencing with a trampoline as a ground plane. “More people share in the fun each year,” says Erik Weaver, N0EW, a Strange Antenna Challenge founder. “I hope you give me a call this year with your very own strange antenna. Now let’s play radio!”

Then the sun disappeared and it became colder.  The heated outhouse was open so I warmed up for a few minutes.
