INTRODUCTION
The Proset-K2/K3 is the result of collaboration between
Elecraft and Heil Microphones to produce a high-performance
headset and boom-mounted condenser microphone optimized
for the Elecraft K2 and K3 transceivers. The Proset – K2/K3
provides excellent frequency response and gain.
Note: The ProSet-K2/K3 is supplied ready for VOX operation.
If you wish to use Push-to-Talk (PTT, you must supply a
suitable normally-open switch and male 1/4” connector. This
connector attaches to the AD-1-K microphone plug adapter
supplied.

SET UP AND OPERATION FOR THE ELECRAFT K3
Important! The following applies only to an Elecraft K3. See the next page if you have an Elecraft K2.
No internal hardware changes are required to use your
ProSet – K2/K3 with the Elecraft K3. Setup consists of
connecting the microphone using the adapter provided,
plugging in the headphones, setting MENU commands and
making other front-panel adjustments.
Note: The jumper blocks and 5.6 k resistor supplied with
your microphone are not used. They are required only when
using the ProSet – K2/K3 with an Elecraft K2.
The K3 can receive microphone input from either front
or back panel connectors. Select the front panel connector as
follows:
1. Tap
M E N U
and locate
MIC SEL
with VFO B.
2. Select
FP.L
or
FP.H
with VFO A.
3. If
FP.H
is displayed, tap the
1
button to toggle the
display to show
FP.L
.
4. Tap the
2
button as needed to display
bI AS
. (This
turns on the bias voltage required by the ProSet –
K2/K3 microphone.)
Plug the 1/8” microphone plug on the ProSet-K2/K3
into the gray jack on the AD-1-K adapter.
If used, plug your PTT switch into the 1/4” jack on the
AD-1-k adapter. (The PTT switch is optional.)
Plug the AD-1-K adapter into the K3’s MIC connector
and the ProSet – K2/K3 headphone plug into the K3’s
PHONES connector.
Chose a voice mode (AM, FM, USB or LSB) your K3
is equipped to operate. Set the K3 power level to 5 W and
make sure an appropriate dummy load or antenna is attached
to the K3. Hold
V O X
to select either PTT or VOX
operation.
Press your PTT button or, if using VOX, speak into the
microphone. You should observe movement on the K3’s
power meter. Adjust the K3 front panel MIC (microphone
gain) and CMP (compression) controls as needed.
This confirms that your microphone is working. Refer to the
K3 Owner’s manual for adjusting your K3 for optimum
results. See Basic Operation, Voice Modes, SSB, AM, FM as
well as Advanced Operating Features.
In Case of Difficulty
If you have problems getting your ProSet – K2/K3 to
operate with your K3, first confirm that you have enabled
the external microphone bias (see the first step of the above
procedure). If this does not correct the problem, please
consult Troubleshooting in your K3 Owner’s Manual.
Also, please feel free to email us at
with your questions.
