Introduction
These reference circuits are intended to help engineers understand current amateur technology for the purpose of interference mitigation. We have researched existing amateur stations to help the engineering communiuty understand what we are using in terms of power level, bandwidth, antenna gain, and receiver sensitivity. Practical, in terms of consumer economics, and practical, in terms of setting a milestone, are often entirely different.
