Application Notes

The TW-1 is primarily intended for visually impaired hams, and those of us more "experienced"
hams who must resort to bifocals, making small meters hard to see at any distance.
The TW-1 is also very useful for special situations when you need to "watch" more than one
meter, as when you are tuning the output stage of a vacuum tube transmitter or amplifier. With
your TW-1 in Tone mode, you can easily watch the plate current meter on the transmitter or
amplifier while listening to the power output on your TW-1 in Tone mode.
The TW-1 is perfectly suited to mobile use. Simply install it in a convenient location near your
operating position, and provide 12 volts DC through a fused line (fuse not included; LDG
recommends a 2 amp fast-blow fuse). SWR Tone mode is especially useful when tuning a
"screwdriver" antenna while watching the road. LDG strongly recommends pulling over to a stop
before adjusting your antenna, but we realize that not everyone does this; you know who you are.
