Controls & Indicators
The front-panel controls for the T-4XB include:
1. Main Tuning Knob: Determines the operating frequency of the device. It features a scale from 0 to 25 KHz, with a main scale divided into 5 KHz steps. The scale can be adjusted by pressing and rotating it while holding the tuning knob.
2. Transceive Switch: Selects the VFO responsible for the operating frequency when used with the R-4B. It has positions such as SPOT, SEPARATE, RCVR, and XMTR, each affecting the operation of the transmitter and receiver.
3. XTALS Switch: A five-position switch for selecting additional crystals. In the NORM position, it allows band switching except for the 1.8 – 3.0 range. Positions 1-4 activate additional crystals for corresponding frequency ranges.
Installation / Setup
The setup highlights for the device include various connection points such as a power supply connector, MUTE socket, antenna connections for receiver and transmitter, and grounding screw. The device also includes connections for Anti-VOX, sidetone, and VOX delay control. The dimensions are specified as 140 x 237 x 295 mm, with an overall depth of 311 mm. For proper operation, a good earth connection is required, and specific connections are necessary for transceive operation with the R-4B receiver. A suitable microphone with a wide frequency response and directional characteristics is recommended for optimal VOX operation. Additionally, when using a linear amplifier, certain connections must be made as per provided diagrams.
Operation
The manual describes the operation and basic usage steps for the T-4B and T-4XB models. Both models support SSB with switchable sideband, telegraphy with automatic switching from receive to send by pressing a key (semi BK), and carrier-controlled amplitude modulation. They can be used on amateur bands from 160 to 10 meters and other non-amateur frequencies like MARS.
The T-4B is designed for transceive operation with the R-4B receiver on the frequency determined by the receiver. The T-4XB is a complete transmitter that can operate in transceive mode with the R-4B or independently for receiving and sending. A switch on the T-4XB allows choosing between transceive operation and independent frequency setting, with either the TX or RX VFO determining the working frequency in transceive mode.
The T-4B can also function as a crystal-controlled transmitter for use in radio networks, MARS stations, DX operations, or as a beginner’s transmitter. Both devices include features like a side-tone oscillator, automatic switching from receive to send in CW, automatic level control to prevent overdrive, a switchable instrument for displaying anode current or relative output, two quartz lattice filters for sideband selection, a switching device for receiver muting during transmission, and VOX or PTT control for AM and SSB.
For transceive operation with the R-4B, a connection between the INJ socket on the T-4B or T-4XB and the INJ socket on the R-4B is necessary. The T-4B and T-4XB are suitable for use with a microphone that has a wide and even frequency response, preferably with directional characteristics for optimal VOX operation. A suitable microphone connector S-260 is included with the devices.
The T-4B or T-4XB should be connected to a good ground, with a grounding screw located at the rear of the chassis. When used with a linear amplifier, necessary connections are detailed in the manual, and AGC voltage can be taken from pin 3 on the power supply connector if available.
The main tuning knob on the T-4XB determines the operating frequency, with a scale from 0 to 25 KHz and a main scale divided into 5 KHz steps. The TRANSCEIVE switch determines the VFO responsible for the working frequency when used with the R-4B. The XTALS switch with 5 positions switches additional crystals, allowing operation on additional ranges.
The rear panel connections include an antenna connection (SO 239 coaxial socket), a receiver antenna connection leading to the antenna relay, a receiver mute connection that mutes the receiver during transmission, and an ANTI VOX/SICETONE connection for ANTI VOX input during reception and side-tone output during transmission.
