IMPORTANT WARNINGS

READ THIS MANUAL CAREFULLY to learn all of the features of the CTX-10. Understanding

that you’ll want to use the radio immediately, we’ve included several Quick Start Guides

right up front.

SAVE THIS MANUAL as it contains important safety and operating instructions.

FCC INFORMATION This equipment has been tested and found to comply with the limits

for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed

to provide reasonable protection against harmful interference in a residential installation.

This equipment generates, uses and can radiate radio frequency energy and, if not

installed and used in accordance with the instructions, may cause harmful interference to

radio communications. However, there is no guarantee that interference will not occur in

a particular installation. If this equipment does cause harmful interference to radio or

television reception, which can be determined by turning the equipment off and on, the

user is encouraged to try to correct the interference by one or more of the following

measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and receiver.

•Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

•Consult the dealer or an experienced radio/TV technician for help.

CAUTION: Changes or modifications not expressly approved by

AeroStream/CommRadio could void the user's authority to operate this transceiver under

FCC regulations.

WARNING RF EXPOSURE! This device emits Radio Frequency (RF) energy. Extreme

caution should be observed when operating this device. If you have any questions

regarding RF exposure and safety standards please refer to the Federal Communications

Commission Office of Engineering and Technology’s report on Evaluating Compliance with

FCC Guidelines for Human Radio Frequency Electromagnetic Fields (OET Bulletin 85).

WARNING HIGH VOLTAGE! NEVER touch an antenna or internal antenna connector

during transmission. This may result in an electrical shock or burn.

WARNING! NEVER operate the transceiver while driving a vehicle. Safe driving requires

your full attention—anything less may result in an accident.

CommRadio CTX-10 User Manual – Rev PRELIMINARY 05 APR 2018

NEVER apply more than 20 V DC, such as a 24 V battery, to the power input jack on the

transceiver rear panel. This could cause a fire or damage the transceiver.

NEVER let metal, wire or other objects touch any internal part or connectors on the rear

panel of the transceiver. This may result in an electric shock or could cause a fire or

damage the transceiver.

NEVER expose the transceiver to rain, snow or any liquids.

DO NOT use or place the transceiver in areas with temperatures below –10°C (+14°F) or

above +60°C (+140°F). Be aware that temperatures on a vehicle’s dashboard can exceed

+80°C (+176°F), resulting in permanent damage to the transceiver if left there for

extended periods.

Introduction

Thank you for purchasing the CTX-10 amateur radio transceiver. Tracing its

evolutionary roots to the commercial/military/avionics worlds, and borrowing

receiver and design elements from the highly successful CommRadio CR-1 and

CR-1a receivers, the CTX-10 is the latest product from the mind of Don Moore,

N0HDX.

The CTX-10 was designed to be rugged and user-friendly with a minimum number

of user interface interactions to produce the desired system functional change.

Standard equipment user replaceable internal Lithium Ion batteries provide power

for a day’s casual operation. The ability to provide operational power and

simultaneously recharge the batteries from most any 5 to 20 VDC source provides

low-cost portable expansion capability and unlimited field operation. Standard

equipment internal wide-range automatic antenna tuner and CW keyer provide

everything you need for full functionality in one lightweight, die-cast aluminum

package with no need for supplementary cooling solutions during high duty cycle

operations.

It is the purpose of this manual to provide you with one source for basic through

advanced operations, trouble-shooting, fielding notes and FAQs. This manual will

be maintained as an up-to-date online PDF document, suitable for printing or

reference on most any electronic device.
