The WJ9J DTMF Controller is...
t
he World’s
MOST
versatile and intelligent DTMF controller board! There is so much more that this board can do other than just control relays! This comes
COMPLETELY assembled
.
This just doesn't turn on outputs when you send 1 digit (as other Chinese controllers which
just use a 8870 chip and a 4-16 decoder and have no brains built in.)
eBay no longer allows me to post links, but search the manual name "WJ9JDTMFControllerV3 ddns"
Some of the applications are:
A
p
plications
:
Remote DTMF On/Off Control of 8 outputs with current status sent back. No longer will you have to "blindly" send DTMF commands.
Remote Base Control of frequency or
ANY
radio with an up memory channel on the microphone.
Camera Pan - Tilt - Up/down control mode
Provide extra features for your existing repeater controller.
Beacon Radio Controller
Repeater Controller Identifier Mode
DTMF Squelch (keep radio quiet until it receives a specific call)
Secure Public Address Application
Logging of DTMF to PC with 1-WIRE output
Solar site control applications with extremely low power requirements.
Some more details around functionality:
Functional Specifications
:
Ability to transmit Morse Code id to identify the transmitter if the status occurs through RF transmitter
Frequency Agile control of ANY radio that has a memory channel up button on the radio. Agile control for between 2 and 255 memory channels
In remote base applications, some outputs assignable to enable RB PTT, and receive enable
Ability to pulse any output with programmable length
Enable a Camera Mode where a 5 and a digit pressed holds on an output as long as the second digit is pressed.
2 modes of CW ID when enabled, Repeater, and Foxhunt Mode.
Supports 1-wire data representation of DTMF digits, for interfacing with a PC, or controlling other devices. It sends a byte via 1-Wire every time a digit is pressed. Other controllers and computers can log this data, or capture if you wish. It is up to you to decide if and how you want to use this feature.
All of the features can be programmed and changed via DTMF. You don’t need to hookup a computer to change.
All changes are saved to EEPROM and do not disappear during a power failure.
A 2 digit or 4 digit password can be created and assigned as active.
This password can be enabled or disabled. No reprogramming is required.
Application notes provide a way to hookup to phone line for control
All outputs can be latched or pulsed. When pulsed, the length of pulse is programmable.
Multiple outputs can be changed in one DTMF sequence.
Programming Configuration Options can be acknowledged by an “OK” message CW (or not)
ON / OFF state can be remembered for same state as before on a power up or can be set to a specific state. This is great if after a power failure, some things need to be on, and some off. In other words, a specific state can be memorized and remembered. Or you can just have it be just as it was when it lost power.
CW callsign identifier can be programmed with DTMF.
CW identifier can be turned on or off.
CW identifier can be sent when a status is or output is changed (or not).
Hardware Specifications
:
8 Logical outputs capable of sinking 100 mA for controlling external relays or devices.
LED Status Indicators are provided for each Logical output.
LED Status Indicators are switchable to an off state for stealth mode or for solar powered applications.
The power is on/off switchable in case you need to power off without unwiring. The switch applies to the screw terminal 12V input only.
LED Power and DTMF Digit Valid Indicator.
Screw Block Terminals for outputs.
Screw Block Terminals or coaxial plug / jack for power supply.
Screw Block Terminals or 1/8” audio jack for audio connection (plug not included).
Power supply: Between 3 and 30 volts.
Current < 8 mA at 12V with the LED status off and < 4 mA when at 3 Volts. Great for solar powered sites.
A relay board is available from a third party vendor.
Comes with Coaxial Plug for DC connection.
Size: 2-9/16" X 3-15/16"
Weight: 2.1 oz (Can be less than 1 OZ with special order without screw terminals)

Coaxial construction 50 Ω Dummy Load with SO-239 UHF Socket
Useful for Amateur/Ham/CB radio use and RF experiments
Brief Description
This dry dummy load has been designed to provide constant 50 Ω impedance to a radio transmitter to allow off air tests and experiments.
The coaxial construction creates a load that presents a more stable resistance to the transmitter output over a wider range of
frequencies, testing has shown the following SWR measurements using a RigExpert AA-230 Zoom, +/-:
3.8 MHz - 1.01:1
7 MHz - 1.02:1
30 MHz - 1.07:1
50 MHz - 1.16:1
70 MHz - 1.22:1
145 MHz - 1.60:1
Constructed from high quality PCB material and using 20 x 1 KΩ 3 Watt Metal Film or Carbon Film resistors (see photos)
the dummy load while air cooled is capable of absorbing RF energy of 40-50 Watts continuously for 1 minute, and up to 100 Watts for several seconds. The load can also be mounted in a can with oil for longer use at 100 watts. Mounting holes in the PCB can accommodate 4/40 bolts that will allow the load to be mounted on a can lid. Some details on how to do this are in the user guide (available on request prior to sale if needed).
Connection to the dummy load is via a high quality SO-239 UHF Connector mounted on the PCB. Overall dimensions are: 2.5" diameter, 3/4" thick (PCB sandwich, excludes SO-239)
