Texas Star DX-667V
750W/62A with onlyToshiba Transistor
(2) IRF520 driving (4) 2SC2879
Variable Power W/SSB Delay
Meter-RF Relative Output Indicator and lights during transmission
Red "POWER" Button turns the unit on and off.
White "REC AMP" Button turns the receive amplifier on to provide 6dB of gain for your receiver. This will work independently of the power button -- that is, the white button may be pressed "on" even when the red button is "off." The oscillator may be operated without any output to the antenna. You will be able to hear the signal in your receiver. This may be useful to adjust your electronic keyer or to practice your Morse Code "off the air."
Green Button reduces power on all models. On models DX 400V and DX 500V, it also activates the RF Output Knob.
Yellow "DELAY" Button reduces power and adds delay to the transmit/receive relay to accommodate different transmission rates for break-in keying operation. On models DX 400V and DX 500V, this button adds delay but does not reduce power.
RF Output Knob controls RF output level when the Green Button is engaged. On the DX 667V only, the RF Output knob is operational at all times.
Meter is an RF Relative Output Indicator and lights during transmission.
A Crystal made for series operation must be installed into the holes labeled "X-1" near the top of the oscillator board. The frequency should fall between 28.0 MHz and 29.7 MHz.
Key Jack for 1/8" miniature phone plug is located on the rear of the unit for connection of the telegraph key.
Power Cables are also located at the rear. The red lead connects to the positive side of the power supply, and the black lead connects to the negative side.
Antenna Connector (SO239) for 50 ohm antenna is located on the rear.
Radio Connector (SO239) for 50 ohm output to the receiver is also located on the rear.
For technician work like the tune up conversion Texas Star Amplifiers do not key up
It needs to be performed before using the amplifier it's a two weeks turnaround time for technician work
So we can provide that great service to our customers high quality
