PLL upgrade board on K2 7109

[EMD]

I think I created a solder bridge between the 1/8W resistor RB and the 3rd pad under the resistor, on the PLL upgrade board.  I have tried to wick up the excess solder but I still cannot determine if this is okay or that the 2 pads should be separate.

  Ed,

Check the schematic.  You will find that one end of RB is connected to
both RC and RD, and further connected to pins 2 and 3.

The troublesome one is usually RE which is close to one end of RC -
those two points should not connect together.

Okay I'm getting ready to install the PLL upgrade board and it looks to me like this has the potential of being a problem.  I have test fit the Thermistor PC board and I can see why the instructions call for the board to lean slightly towards U6.  The problem I see is the position of RFC14 and the PC board.  Any tips in getting it installed correctly.  One thing I have done is to make sure the leads coming out of the board make a tight 90 degree bend out of the board as to give me better spacing on RFC14.

  Ed,

Your tight 90 degree bends alone will do the job.  There will be space
for RFC14 and the capacitor at its end too even though it is a tight fit
for the capacitor - it is not too tight.
I just finished a K2 RF board a few minutes ago, and had put RFC14 and
the capacitor in yesterday and had no problem.
