+Layout Changes
+- Move all of the following to the upper left side of the board, and 
+    lay out like on page AN85-2 of app note
+      - C284-C287, C296-C298
+      - U205
+      - L203, L204
+      - D201, D202
+      - R204, R205
+- Move C282 to top side, right near U209 pin 16
+- If possible, move C280 and C281 to top, near U209 pins 7 and 15
+- Put direct traces between top layer decoupling caps and power pins
+    of U103
+- Put C130-C135 on top layer (this avoids vias in filter)
+- Add a little space between L102 and L107.  Same for L105 and L109.
+    This gives better IQ isolation.
+- R21X labels are on vias (on back)
+
+Part Value Changes, same footprint
+- C284, C286 (4.7uF ceramic) are now X5R, and are 35V or 50V rated
+- R204 is now 9.53K, 1% metal film
+- L203 is a 1206 Ferrite Bead
+- R95 is now 1K
+
+Footprint Changes, same part
+- C47, C126, C208, C228 changed from 1206 to 1206P to get polarity indicator
+
+
+Part Changes, different footprint
+- C284 changed from 0603 to 1206, same part as C286
+
+Schematic changes, added parts
+- Added C296, C297, C298 to switcher
+- Added C42, place it right next to U7
+- Added C270, R252, R253, place them near U208
+- Added C254, should be placed right at U207 pin 14
+
+
+Schematic changes, removed parts
+
+
+Connectivity changes
+- U207 now on 5V_COM (was on 5V_RX)
+- Switcher now on 6V_TX (was on 5V_COM)
+- Got rid of 3_3V_SW, now on 3_3V_COM net
+
+
+
+Open Issues
+- 3 attenuators (make chip attens) (at source or at dest?)
+- Remove transformer in LO-testing path
+- Loop filter
+- Separate 3 TX enables
+- RSSI?
+- LNA Layout
+- Examine all RF paths
+- Bypass L113, L114
+- T2, T100 line straightening
+- Revisit RX enables
+- Transformer in LNA path?
+- Add power amplifier
+- 64 Mhz termination and filtering? keeping it clean?
+- Open up space on left of U2 -- too much coupling
+-
