While every voice is different, these guidelines from Heil will serve as satisfactory starting
points for operation. Read the particular transceiver's operating manual for more details.
Icom 746/756 Pro, 7600/7700/7800
Set Treble to +4, and Bass to -4. Use COMP Wide/Mid/Nar for high-fidelity, HC-5, or
HC-4 (DX) emulation.
Yaesu FT-1000MP Series
Set Menu 5-9 to 6.0, and Menu 7-7 (SSB-T) to 100-3100 for high fidelity, 300-3100 for
DX. Leave Menu 4-4 off, or try selection "3."
Note: The FT-1000D, the predecessor to the MP series, does not have any DSP and,
hence, no DSP equalization. However, the HC-6's articulation is such that it sounds great
on the FT-1000D, still a popular transceiver among elite DX operators.
Yaesu FT-950/2000, FTdx5000/9000
Set EQ1 to 200 Hz, -8 dB, EQ2 to 900 Hz, -4 dB, and EQ3 to 2000 Hz, +6 dB, all with a
bandwidth of "2." Remember that there are separate "Processor On" settings. Use SSB
Transmit Bandwidth menu for high fidelity (100-2900 Hz), everyday (HC-5) operation
(300-2700 Hz), or DX (HC-4) work (400-2600 Hz).
Set the equalizer to "2" for everyday operation, or "9" for DX and contest work.
Set TX EQ as follows: 0.05 to -12, 0.1 to -10, 0.2 to -6, 0.4 to -2, 0.8 to 0, 1.6 to +4, 2.4
to +6, and 3.2 to +10.
Set TX Bandwidth to 3000 Hz, and TX EQ to "C" for everyday operation, or "H" for DX
and Contest work.
Set Menu 19 (DSP TX EQ) to "C" for fidelity, Hi Boost 1 for everyday operation (HC-5
emulation), and Hi Boost 2 for DX work (HC-4 emulation). Set Menu 20 (TX
Bandwidth) to 2.4 kHz in most cases, or 2.0 kHz for extreme DX work. Note that the
transmitter bandwidth will not expand beyond 2.4 kHz.
Ten-Tec Orion II/Omni VII
Set TX Filter Bandwidth to 2700 Hz, LF Roll-off to 200 Hz, and TX EQ to 0 for fidelity,
-6 for everyday operation (HC-5 emulation) and -12 for DX/contest work (HC-4
