[R-390] Balanced input on higher bands correction

[Jordan Arndt]

Hi group and Happy Holidays...

Sometime back I responded to a post stating that my 390As all had an issue 
above 15-16Mhz when connected to my ~90 foot wire via the balanced antenna 
input...

The problem was not the antenna or the balanced input. The real problem was 
that I was temporarily using an 18" jumper to ground one side of the 
balanced input connector to the chassis.

Once I replaced the 18" jumper with a 2 inch wire grounded to the mounting 
screw just below the balanced input connector, the sensitivity was restored 
from 15 to 32 Mhz. In fact, I'm surprised at how much of a difference the 
length of that connection made...

Live and learn...!
