The very first Hamboree was held at that same site in 1977.


All of the above is loosely structured; no need to worry about formality. Everyone is welcome to join us, and though membership in the 3900 Club is not required, but is encouraged.

Thank you for being a part of our Sunday mornings!

Lifetime membership originally cost $1.00. Fifty years later, it is still only $5.00. There are no annual dues. Current membership is approximately 1500 & covers 31 states.

Beginning as a one-day gathering, it grew to two full days of activities. A large swap meet / flea market featured several full-line exhibitors, who brought a good stock of both new & used equipment. Seminars on varied topics of interest, license exams, ladies' programs, QCWA luncheon meeting, and Friday & Saturday night dinners, all combined to provide something for everyone, from novice to extra-class. Often, the ARRL Midwest & Dakota Division Conventions have been part of the Hamboree activities.

Following an extremely successful ARRL convention at the South Sioux City, Nebraska, Marina Inn, in 1974, the 3900 Club, along with two other local amateur organizations, decided to try a similar event.

A typical Sunday morning schedule is as follows:
(all frequencies are + or - QRM; times are CST)

Much growth in membership followed -- and some growing pains. FCC frequency changes, license restrictions, interference with other nets, and outside QRM all contributed to the net's inability to settle on the desired 3900 frequency permanently. For many years now, 3897 has been a stable spot for the Sunday morning gatherings, which begin at 8:00 Central time.

The following year it was first publicized as an annual convention.

The Radio Amateur is:

CONSIDERATE ..... never knowingly operating in such a way as to lessen the pleasure of others.

LOYAL ..... offering loyalty, encouragement and support to other amateurs, local clubs and the American Radio Relay League, through which Amateur Radio in the United States is represented nationally and internationally.

PROGRESSIVE ..... with knowledge abreast of science, a well built and efficient station, and operation beyond reproach.

FRIENDLY ..... with slow and patient operation when requested, friendly advice and counsel to the beginner, kindly assistance, co-operation and consideration for the interests of others. These are the hallmarks of the amateur spirit.

BALANCED ..... Radio is an avocation, never interfering with duties owed to family, job, school or community.

PATRIOTIC ..... with station and skill always ready for service to country and community.

The 3900 Club began in the 1960's as a Sunday morning net of a dozen ham radio operators in, and

around, the Sioux City, Iowa, area. The club was formally organized in September, 1969.

Since 2012, Hamboree activities have been scaled back to a one-day, more casual event, due to prevailing interest levels and economic conditions.

Our co-founder, leader, and net control for many years was Dick Pitner, WØFZO. His ability to take charge of any situation was enviable, and his leadership has been missed since his key was silenced in 1996. The net still uses his call as its own.

What Is the 3900 Club?

The 4th Sunday of each month is "Vintage Radio Day", when the tubes glow the brightest, and the 5th Sunday, if there is one, is "AM Net Day", and a short section of the net is run on AM to exercise this old-time mode.

Two board meetings are held each year, one on the Friday night prior to Hamboree. The second is in the fall at a time and location determined by the board members, with a general membership meeting and luncheon following.  Anyone desiring to have a copy of the minutes of those meetings can contact the current Secretary/Treasurer at
