These corrections and updates apply to the original article presented at the
Microwave Update'99 Conference in Plano, Texas and published in the Proceedings of
1. On page 127 of the original article, Figure 1 shows the Synthesizer programming
results for the desired 11,360 Mhz LO frequency. The Figure incorrectly shows that
the M register settings for both M4 and M3 are controlled by Pin 1 of the 3216 Synthesizer
chip. Instead, the correct pins are as follows: M4 (Pin 13), and M3 (Pin 10). These
are shown correctly in the web page version of the article, in Part One.
2. The original article inadvertently omitted a necessary Modification
to the X5 Multiplier which requires the addition of two tuning stubs. Lack of
this modification will result in low LO output to the Tx and Rx mixers.
