OPTIMOD-AM 9200 VERSION 3.0 SOFTWARE ADDENDUM

About This Addendum

This publication is an addendum to the Optimod-AM 9200 Version 2.0 Upgrade Instruc­tions and to the 9200 Operating Manual. It describes improvements to the 9200 added by
versions 2 and 3 software. It should be used in conjunction with the main 9200 Operating
Manual and the 9200 PC Remote Software V3.0 Operating Manual.

• The 9200 Operating Manual Addendum contains complete information about Ver-

sion 2.0 features not described in the main 9200 Operating Manual.

• The 9200 PC Remote Software V3.0 Operating Manual contains complete instruc-

tions for installing, configuring, and using 9200 V3.0 PC Remote Software.

• If you are upgrading an existing 9200, please refer to the included 9200 Version 2.0

Upgrade Installation Instructions for information on how to replace your 9200’s
ROM. This information is equally applicable to version 2.0 and 3.0 ROMs.

Version 2 Software

Version 2.0 includes:

• New presets for HF broadcasting

• Day and Night positive peak control for improved nighttime coverage

• Front panel security lockout.

9200 HF Presets

The HF presets have been designed to meet the exacting needs of international shortwave
broadcasters: one preset is for general programming (voice and music), one is for voice
programming, and the third is for voice programming in the presence of extremely poor
propagation conditions, including jamming.

The presets share the 9200’s unique receiver equalizer, which compensates for receiver
high-frequency rolloff and dramatically increases speech intelligibility, but they go a step
further. Your sound will benefit from a dynamic presence lift and considerably less bass
than that offered with the 9200 presets for medium wave transmission, maximizing intel­ligibility on narrowband radios. What’s more, the presets’ well-controlled bass can help
reduce your transmitter’s power consumption and increase the life of expensive power
tubes.

Of particular importance to the high-power HF broadcaster is the 30dB/octave highpass
filter. This is adjustable from 50 to 100Hz in 10Hz steps. Regardless of cutoff frequency,
it always includes deep notches at 25 and 35Hz to protect the power supplies of certain

high-power transmitters. Broadcasters transmitting primarily speech programming may
want to set this filter’s cutoff frequency relatively high to further maximize tube life and
minimize power consumption.

The three HF presets are derived from two basic presets,
each with full

MAXIMUM

All presets are initially set for 4.5 kHz lowpass filtering, 50 Hz highpass filtering, and a
gentle bass rolloff. However, like any other 9200 factory preset, you can adjust these (and
many other) parameters and save the result to a user preset. For example, the 4.5 kHz
lowpass filter provides a very steep rolloff, so HF broadcasters may find that they can set
it to 5.0 kHz without causing objectionable adjacent-channel interference.

The 9200 has a bypass facility that includes the lowpass filter, highpass filter, and a safety
clipper (with user-settable threshold). This allows you to make transmission system
measurements through the 9200 while protecting high-power transmitters from damage
due to application of inappropriate levels or frequencies.

Orban’s analog Optimod-HF 9105 has achieved widespread acceptance amongst the
world’s most prestigious national HF broadcasting organizations. The HF 9200 presets
have been tuned to sound as close as possible to the 9105, and we believe that they will
be equally proficient

LESS/MORE control. The third, “flame-thrower” preset called HF

is identical to HF VOICE except for a much higher LESS/MORE setting.

Day and Night Positive Peak Control

V 2.0 has separate day and night positive peak settings, providing you with the highest
fidelity during daytime broadcasts and the largest signal coverage at night, when higher
levels are processing are appropriate to cut through skywave interference.

In V 1.0 software, the
setting was applied to the output at all times. Version 2.0 replaces the single positive peak
control with separate
