Let's try spaces instead of tabs for the tables.

Here's a summary of the sums of the scale readings (side1 plus side 2). 
Keep in mind that I may have switched scales from band to band but it is the
relative numbers in each row are all on the same scale.

Band    JMB    Direct    4to1    1to1
          Sum   Sum	      Sum     Sum
160      X        84         71        75
80       73       62         67        65
40       124     87        108       84
30       93       75        101       88
20       73       149       61        42
17       140      117      135       117
15       75       80        80        80
12       50       49        57        55
10       70       65        73        67
6         X         44        44        45
  
Here's a summary of the differences of the scale readings.  The smaller the
better. The direct case is pretty poor except for 160m and 6m.

             JMB       Direct    4to1      1to1
