Operation 
 

To operate your FT-Meter you just, well, operate. The meter has no controls and requires no input 
from you. Simply use your transceiver normally, and your FT-Meter will continuously display the 
selected parameters. 

 
Application Notes 

 

Base Station Use 

 

Your FT-Meter can go practically anywhere on your operating desk. The three foot cable gives 
you a lot of latitude in where you place it. Some obvious choices are on top of the radio or beside 
your computer monitor.  

 

Mobile Use 
 
The FT-Meter is ideal for mobile operation. You can mount the meter on the dashboard with 
Velcro tape in any convenient location. The meter is 

much

 easier to read than the radio's display, 

especially if the radio is mounted at any distance from the driver's position. 
 
If you choose to connect the 12 vdc input to light up the meter, be sure to use a fused power line 
(not provided by LDG). LDG recommends a 1 amp "fast blow" fuse. 
 
Mobiling with the FT-Meter is great, but don't be distracted by its beautiful face; keep your eyes 
on the road! 
 
Other Applications 
 
LDG designed your FT-Meter specifically for the Yaesu FT-857 and FT-897 transceivers, and 
does not recommend using it in any other application. However, the meter is in fact simply a 500 
micro-amp meter movement; the calibration potentiometer gives you a range of .5 - 2 ma. If you 
choose to use it in a different application, take care not to exceed the maximum current 
specification; the meter movement will be damaged or destroyed by current in excess of this 
specification.
