communications (HF/VHF/UHF), ELTs and SELCAL,
plus TCAS I/II and TACAN. Release 3, targeted for
September 2019, will include the features of Releases 1
and 2, plus GPS position simulation.
Technical specifications include a frequency range
from 200 kHz to 2 GHz and six-plus hours of battery life
from a device weighing 4.5 pounds. The SDR-OMNI will
come with a two-year warranty. Accessories include a
directional antenna, a telescoping antenna, an RF Cable,
VSWR calibration kit and a transit case. The device
includes a USB port, Wi-Fi and an audio jack. It can be
used as a handheld device, mounted to a tripod or placed
on workbenches and tables with a "kickstand." Thanks to
the Wi-Fi capability, it can be controlled from an Android
or iOS device, or from a laptop. Testing results are saved
and can be shared in several file formats.

Trans-Cal Industries
Trans-Cal Industries offers avionics and test equipment,
computer peripherals and industrial process controls,
including a popular line of altitude encoders. New for
2018 from Trans-Cal is the model SSD120-35C-RS232
series altitude digitizer/encoder, with an altitude range
from -1,000 to +35,000 feet.
The devices are all-solid-state, providing rugged and
reliable measurement of air pressure and conversion to
industry-standard data. They output one ICAO (grey
code) data stream and on two asynchronous serial RS232
ports, the type of interface commonly used by ADS-B
Out surveillance equipment, GPS navigators, autopilots,
transponders and other avionics. Six serial data protocols
are available, selected through internal shunts or via
software.
The SSD120-35C-RS232 is approved under FAA
TSO C88a and ETSO C88a, and has been tested to
conform with MIL-STD-704E and RTCA DO-160E.
Operating voltage is 10-33Vdc, and the operating standard
temperature range is -20 to +70 degrees Celsius. It weighs
4.3 ounces, comes with a 42-month warranty and has a
calculated MTBF in excess of eight years.
"We're now producing and able to ship them,"
Trans-Cal President John Ferrero told AEA Convention
attendees. "It's our same electronics, just repackaged into
a less-expensive solution. You get the same overall quality
you've come to know from Trans-Cal. This unit was
designed and developed to compete head-to-head with the
least expensive of the altitude digitizers on the market."

The SSD120-35C-RS232

The Trans-Cal SSD120-35C-RS232 is a direct pin-forpin replacement for most in-service ACK units; adapter
plates to simplify installation and minimize installation
also are available. Warranty coverage includes direct
replacement by the company: Upon verification of a
covered failure, the unit is replaced with a new one, which
comes with a new warranty.

TruTrak Flight Systems
TruTrak got its start in 1999, and by 2000 had produced
its first autopilot prototypes. In 2002, the company started
shipping its first product, the DigiTrak, and has sold more
than 10,000 autopilots since then. Until the last couple of
years, all of its products targeted the experimental aircraft
market. But in 2017, it began selling its Vizion autopilot
as a PMA'd device available with an FAA STC. At the
2018 AEA Convention, TruTrak President Andrew Barker
updated attendees on current and future STC approvals,
and more.
"As of right now, we have approvals for (Cessna
models) 172, 175, 177, (Piper) PA-28 and PA-32s,"
he said. "That's around 65 models in total we have
approval for."
