K2K New Hamshire will be operating all modes on 160m – 6m (except for 60m) and on Satellites as well. We’ll have a QRP station (K2K/QRP) as well.

The 2019 Thirteen Colonies Special Event begins today. Get on the air and work all Thirteen Colonies as K2A – K2M and don’t forget the two bonus stations – WM3PEN and GB13COL. Have fun!

HAB-4 to Launch on Sunday from Hollis-Brookline High School

We are planning the fourth launch of our High-Altitude Balloon (HAB-4) this Sunday, June 9th between 10:30 am and 11:30 am ET. We will be launching locally from the Hollis-Brookline HS here in Hollis, NH. Read on to learn more about our HAB projects and how to track our HAB while it is in flight.

You can learn more about our HAB projects here on our website and you can view a video about our first three HAB launches above.

High-Altitude Balloon Launch Site and Weather

The weather and Jetstream conditions look good for our HAB-4 launch! The jet stream has finally settled down to a point that will enable us to launch locally from the High-School here in Hollis, NH. Nashua Area Radio Society members and friends are invited to join us for our launch.

We have been working with students at the Hudson Memorial School and Bishop-Guertin High School here in NH. The students and their teachers will handle HAB-4 launch preparations and the launch. Launch preparations will begin on site at 9:00 am ET.

Weather Forecast for our HAB-4 Launch

The weather forecast looks great for our launch on Sunday with mostly sunny skies and moderate winds. These conditions should enable us to capture some spectacular video from HAB-4 during its flight! We are also planning to live-stream video from our HAB-4 launch and recovery to the Nashua Area Radio Society Facebook page.

Tracking Our HAB

I wanted to share some information about tracking our HAB as it flies. Our balloon will carry a GPS receiver and a 2m APRS Transmitter.

HAB Flight Platform
HAB Flight Platform

The onboard APRS transmitter will operate on the Amateur Radio standard terrestrial APRS frequency of 144.390 MHz and will transmit our HAB’s position, heading, speed, altitude and other telemetry data every minute during HAB-4’s flight. The transmitter is battery-powered and generates a 250 mW signal into a dipole antenna suspended from HAB’-4s flight platform. HAB-4 will use N1FD-11 as its call sign.

HAB-4’s APRS packets will be picked up by ground-based Digipeaters and iGates and will be relayed to aprs.fi where the HAB’s current location and flight path can be tracked.  You can click on the link in the previous line to see HAB-4’s current location and flight track.

HAB-4 Flight Path Prediction
HAB-4 Flight Path Prediction

Based upon online HAB flight prediction calculators that we have been using, we expect the HAB’s flight to last a little more than 2 1/2 hours. The HAB should reach an altitude of about 110,000 ft before the balloon bursts and the parachute on the flight platform brings HAB-4 back to the ground at a safe speed. The above predictions will likely somewhat different from HAB-4’s actual flight path. Based upon the predictions, HAB-4 will be traveling approximately 42 km between its takeoff point and landing near Marlborough, MA.

HAB APRS Packet Information

Aprs.fi will store and display a copy of all of the APRS AX.25 packets transmitted by HAB-4 during its flight. Of particular interest to the STEM element of the flight will be the Balloon’s data on atmospheric temperature and pressure conditions at different altitudes.

All you need to track HAB-4 during its flight is Internet access and a web browser. Just click on one of the aprs.fi links here to see HAB-4’s current location and altitude. If you have an APRS ground station, you may also be able to receive HAB-4’s telemetry directly during the flight.

We will post updates on launch plans and the flight in the Youth Forum on our website.

You can join us for the launch. Here’s a map showing how to get to our launch site.

June 2019 Contest Notes

The beginning of June marks the unofficial start of Summer. There are still the various state QSO parties you can work (see Contest Calendar dot com), but the weather is finally nice! Wouldn’t you rather get out of your shack and operate in the great outdoors? June is a great month to operate VHF/UHF from a mountaintop, QRP portable from a picnic table, or with your friends on Field Day.

June Contests

ARRL June VHF Contest [1800Z June 8 to 0259Z June 10]

Exchange: Maidenhead grid square (RST is optional)

Go to the top of a mountain with your all-band, all-mode radio. I’ve done VHF contests QRP with an FT-817 (now being sold as the FT-818). These radios are not very economical with your batteries, but since I was driving to the top of the mountains when I did this I could bring all the power I wanted. No problem! Other radios such as the FT-857D offer the same all-band and all-mode features but have 100 watts.

I’ve always been partial to Icom radios (if I can’t use an Elecraft), so the IC-7000 was a go-to radio for me. Same deal with being something of a power-pig. But, if you’re operating from your car then you have no problem.

Finally, if you do have a hankering for Elecraft, the KX-3 can take an internal 2-meter module that allows you to run on both 6m and 2m. If you can’t bring a whole power plant worth of power with you then this is an excellent option.

ARRL Field Day [1800 June 22 to 2100Z June 23]

Exchange: 11A NH (“11 Alpha New Hampshire” on phone)

The NARS club is going all-out (again) this year planning an 11A. There is so much going on for this event that I won’t even try to give you a synopsis here. To catch up go to the Field Day page and see the fine article written by Fred.

I can’t emphasize enough how wonderful Field Day can be to someone a little tentative on the air. Field Day is a very relaxed event, and there will be a whole host of Elmers present that WANT you to get into the game. We will sit with you, explain everything, let you make some contacts, give suggestions and encouragement, and generally have fun because YOU are having fun!

Please come to the June main membership meeting, and the June Tech Night to receive the full orientation. If you can’t make those meetings, no worries. The point of the meetings is to help the members feel comfortable and informed (and safe) during the event. There will be additional instruction before on-air activities begin.

Until next time

This concludes the June contest notes. I hope all of you with a portable radio will try to get outside and make a few contacts. SOTA, POTA, and IOTA all have programs that reward the adventurous. Get out there and get a little sunshine!
