Heathkit HD-1410 Instruction Manual page 2

The HD-1410 is a compact Electronic Keyer with a built in AC power supply, mechanical paddles,
sidetone oscillator and speaker in one package. It is designed and styled to complement the "SB"
Series and is compatible with virtually all modern transmitters and transceivers, as well as most
older rigs.
The following features make the Electronic Keyer versatile:
"Iambic" operation – Lets you form many Morse code characters with less wrist movement
than is required with keyers that lack this feature. If the two independent paddles are treated
as one, operation is identical to single-paddle keyers with dot and dash memories. Dots and
dashes are self-completing, and proper ratio is always maintained.
Built-in sidetone oscillator and speaker with adjustable tone and volume.
Headphone jack an the rear panel that silences the speaker. Receiver audio is fed to the head-
phones by a separate rear panel jack.
Built-in paddles have excellent "feel" and easily adjustable for tension and travel.
Solid-state output eliminates the bounce and sticking problems associated with relays.
Weighted cabinet to prevent the keyer from sliding on the operating surface.
Rear panel jacks are provided for an external key and for operation from an external battery
(polarity protected) for portable operation. The line cord disconnects from the Electronic Keyer
for battery operation.
Front panel "Hold" switch allows transmitter tune-up.
Low profile styling and small size permit the Electronic Keyer to be set in front of most Ham rigs
and not block controls or take up valuable space. The versatility and reliability of this Keyer will
make it a welcome addition to your Ham station for years to come.
