2. TAPR has no paid engineering staff
TAPR has no paid engineering staff. All the projects over the years were developed by hams who had an idea and brought it to TAPR for support or encouragement. Projects typically go through the process of building a few prototypes which get tested by a small group of those interested in the project. Once the design is finalized, TAPR does what in effect is a group purchase of parts which are then kitted and sold at a price that includes a small mark up to offset operating expenses.
TAPR is not just about projects and kits
TAPR provides ongoing communications - spreading the word - for all interested parties
Mail lists / SIGs
PSR - Packet Status Register quarterly newsletter
ARRL-TAPR Digital Communications Conference (DCC)
Hamvention forums and booth
Encouraging international amateurs to present at DCC or Hamvention forums

3. TAPR continues to push the envelope by producing HPSDR boards and kits, by supporting the early development of Codec2 and spreading the word via forums and the DCC. TAPR also supported the initial development of Whitebox. TAPR continues the expansion of Time and Frequency related kits.
TAPR is a community that provides leadership and resources to radio amateurs for the purpose of advancing the radio art.
