The manual for the Drake FR-4tr covers the setup, operation, and troubleshooting of the frequency readout device designed to interface with specific R. L. Drake transceivers. It provides detailed instructions on installation, including unpacking, location, and connection procedures, as well as operational guidance and troubleshooting tips for ensuring proper grounding and addressing potential issues with frequency readings.
Manual Overview
The Drake FR-4tr manual provides detailed guidance on installation, operation, and troubleshooting of the frequency readout device designed for R. L. Drake transceivers. The manual emphasizes the importance of proper installation to avoid service issues, including ensuring adequate ventilation and grounding to prevent interference from RF fields. The installation process involves connecting the FR-4tr to the transceiver using a supplied interface cable kit, with specific instructions on routing and securing cables. For operation, the manual outlines the use of a band switch to select the appropriate frequency band, noting that the readout will display an internal conversion number until the transceiver is powered and warmed up. Troubleshooting guidance includes checking grounding if frequency readings are unstable during transmission. The manual also describes the FR-4tr’s internal sub-circuits, including signal conditioners, time base, counters, and power supply, providing a schematic for further technical reference.
Quick Issues Covered
- Diagnose power-up failures with FR-4tr frequency readout.
- Calibrate FR-4tr for accurate frequency display on Drake transceivers.
- Use schematics for circuit tracing and troubleshooting FR-4tr issues.
Overview
The model FR-4tr is a frequency readout device designed to work with amateur radio equipment, specifically interfacing with the TR-3, TR-4, TR-4C, and TR-4CW series of transceivers manufactured by R. L. Drake Company. It provides both transmit and receive frequency displays and can be used at a fixed station or operated from mobile or portable power, except on the 10-meter band.

Installation / Setup
The installation of the FR-4tr involves several key steps:
1. Unpacking: Carefully unpack the FR-4tr upon receipt and report any damage to the carrier immediately.
2. Location: Ensure the vent holes on the top and bottom are not blocked and do not remove the feet to allow air circulation. Avoid extending the supplied cables.
3. Connection to R. L. Drake Transceivers:
– Place a soft cloth on your workbench and turn the transceiver upside down.
– Remove the six black screws from the bottom of the unit.
– Use the interface cable kit to connect the FR-4tr to the transceiver, following specific steps to attach cables and screws as outlined.
– Route cables appropriately and replace the transceiver bottom.
– Position the transceiver normally and place the FR-4tr within cable reach, often on top of the transceiver.
– Connect the phono plugs to the appropriate jacks on the FR-4tr and power it with 105-130 VAC.
4. Grounding: Use a properly grounded station setup to prevent frequency reading issues due to RF fields. A ground post is provided on the back panel for this purpose.
Operation
Once connected to your transceiver, the FR-4tr is ready to read out frequency. After applying power to the transceiver and to the readout by placing the POWER switch in the up position, set the three-position BAND switch in the proper position as indicated:
– BAND SWITCH POSITION
– 10 m: Norm
– 15 m: Norm
– 20 m: 20
– 40 m: Norm
– 80 m: 80
Note that the readout will display a meaningless internal conversion number when the transceiver is off or until it warms up.
