PSK-31 on an iPad: A Personal Journey
1:30 PM
Kristen McIntyre, K6WX
Technical Coordinator, East Bay Section, Pacific Division, ARRL

"Sometimes frustration, not necessity, is the mother of invention. In this case, it motivated me to create a PSK-31 implementation for the Apple iPad. In many ways, iPad is an ideal platform for digital modes. While the code is still incomplete, it was a fascinating journey through the PSK-31 specification and protocol, signal processing theory, other people's code, and sleepless, coding-impassioned airplane flights through Asia. This culminated in the first six QSOs that we know of using iPad being done in late January 2011 at Amateur Radio Technology Day. Join me as I take a look back at why I did this, some of the inner workings of PSK and other signal processing pieces, and where it might lead in the future." [edit]

At the SLAC National Accelerator Laboratory


SLAC has graciously given us use of a large indoor and outdoor activity area, including a large auditorium and a picnic area to practice and demonstrate our amateur radio skills.


With beginnings in October, 2004 at the Sunnyvale Baylands Park, to our present location at the SLAC National Accelerator Laboratory starting in January, 2005, the many individuals involved over the years have made the Am - Tech Day experience an interesting one, indeed.


The activity's duration, spanning most of the day and into the evening, allows Amateur Radio Operators and their friends to attend before, and/or after, any additional daytime/evening tasks and activities they need to accomplish.


Please bring and wear your Ham Radio organizational name badge if you have one! We will also have temporary name badges available for your use.


The participant supported lunch with hamburgers, hot dog's, veggie burgers, chips, soft drinks, etc., will be on hand to enjoy.


Even if you don't have a radio or antenna to bring, come anyway, and get to mingle, make new friends, and have a chance to use some of the gear other hams have set up. Bring your family and friends!


We usually have at least one lecture on the latest ham technology. But if the lectures don't interest you, mingle with the crowd, and you'll surely find another ham that can teach you about operating in general or about the latest cool thing.

Amateur Radio Technology Day — Notes & Directions


SLAC is providing the space, but you bring all the equipment and food you need. A BBQ grill, charcoal, and refrigerator are available.

  • Show a photo ID at the gate, and sign-in at the table inside the building.
  • AC power supplies and amplifiers must be UL-listed, have a similar safety endorsement, or be approved by the SLAC Electrical Safety Officer.
  • A limited number of AC outlets are available inside and outside, but since we're not allowed to plug power strips into extension cords, bringing along a 35'-100' extension cord with multiple built-in outlets would be quite helpful.
  • Gel-cell batteries 50 amp hours or less are allowed, so long as there are no exposed conductors. Use electrical tape, shrink-wrap, or similar materials to cover the terminals. No wet-cell batteries or car/truck batteries are allowed.
  • Alcohol, firearms, flammable liquids, and other dangerous weapons are strictly prohibited.

We have free use of this great site, but we need to comply with the SLAC, OSHA, and fire marshal safety rules. For those who are curious, we need to comply with NFPA-70E and OSHA 1910 (subpart S) electrical safety regulations.


Amateur Radio Technology Day can be reached easily from Highways 101 and 280. SLAC is located off of Sand Hill Road, less than a mile east of Interstate 280 (towards the bay).

  • From U.S. 101, turn west onto either University Avenue or Embarcadero Road, then turn right (north) onto El Camino Real and then left (west) onto Sand Hill Road, and continue approximately 2.6 miles west, turning left at Saga Lane.
  • From Interstate 280, turn east (towards the bay) onto Sand Hill Road, and proceed approximately 0.8 mile, turning right at Saga Lane.

Once you turn onto Saga Lane, turn left after the guard shack onto Loop Road and follow the signs to the parking lots below Panofsky Auditorium, located around the bend (Parking lot C). Park and walk up the concrete path to the buildings.
