User’s Manual 144MHz Band 300W Power Amplifier Model HL—355VIQ( TOKYO HY—POWER LABS, INC. The HL—355VKX is a 144MHz Band Linear Power Amplifier with the maximum output power of 300W (320W max,), designed with Tokyo Hy—Power’s accumuiated VHF technologies. Four pcs. of high gain RF FETs, RD70HVF1, by Mitsubishi Electric are used at final stage in the parallel push-pull amp. form. Due to its high gain HL-355VKX accepts wide range of drive power from 1W to 50W, achieving 25W to 320W of output power. This is a completely solid-state amplifier capable of handling all transmission modes. There is a built-in super low noise GaAs FET RX pre-amp that helps operator receive weak DX signals. 1. Main Features 1. Latest LDMOS FET: 2. Adoption of Multi—Protections: it incorporates four kinds of protection circuits developed by our own advanced technologies. This sophisticated protection gives you a warning (shut-down) before getting into any trouble. 3. LED Output Level Meter: LED bar graph on the front panel indicates an approximate output power to monitor transmission status. 4. Low—Noise RX Pre—Amp: It incorporates a low-noise RX pre-amp utilizing a performance-proven GaAs FET. More cozy VHF communication can be enjoyed with the HL—355VKX. 5. Auxiliary Remote Controlling Function: A jack for the connection with a remote controller (optional HRC-GO) is provided on the rear panel. Remote controlling of the power supply, the RX pre-amp and so forth can be controlled in the remote location. 6. Large Aluminum Heat Sink Large heat sink of our original extrusion design effectively radiates the heat generated at the final FET transistors. 2.

With the first push, the switch will be locked, turning the power ON. And POWER LED lamp lights. With the second push, the knob will be released to turn the power OFF. 2 RX AMP Power switch for RX preamp. RX amp works independently regardless of ONIOFF positions of POWER switch. 3 MODE (FM/SSB select) Switch for selecting time lag of RF key circuit, when changing from TX to RX (stand-by). When pressed for SSE/(CW), time delay is one second, and when released for FM/(AM), there is no delay. 4 PROT (Protection LED) Protection circuit will trip for high antenna SWR (when reflected power is 30 W or wigher). 5 POWER LEVEL Six LED lamps indicate approximate TX power level of amp. If all six is lit, output power is approximately 250 W. ® L._._.: 6 TX W (N, Input Connector) Connect the coaxial cable from the transceiver. Any kind of radios such as handheld, mobile, and base station use can be combined. 7 A001 (Accesson/1 RCA Jack) Hard-key connection socket when TX to RX change over is made without time delay. (Desirable for SSB/(CW)) If DC voltage of +3V~+15V is applied to center pin, TX amp will be switched to TX ON state. (Refer to manual of your radio for positive DC voltage pin assignment.) 8 A002 (Accessory 2 RCA Jack) Hard-key connection socket to use in the same manner as ACC1 . lf center pin is grounded through control circuit of your radio, TX amp will be switched ON without delay. (Refer to radio ‘5 manual.) 9 DC13.8 V (DC Power Connector) Connect to regulated DC power supply or 12 V battery system using included DC power cord. (Red is positive and black is negative.

Various Protections When the following Protection trips, ”PROT" LED will light and amp will be shut down. 1 Over Temperature (LED lights solidly) When the internal temperature reaches 70deg. C or above, “PROT”LED will light. (Leave the amplifier in STAND BY mode until temperature descends well.) 2 Over Voltage (LED blinks in series two times) When DC line voltage exceeds 16V, “PROT” will light, and LED blinks. (Check the DC power supply. If the RF stray is the suspect cause of failure, use some clip—on ferrite cores at both ends of DC power cables.) 3 High Antenna SWR (LED blinks) When the reflected power from antenna exceeds 30W, “PROT” will light, and LED blinks. (Check the antenna SWR.) * When the “PROT” above trips, turn off POWER switch once and check the suspect cause of failure. Turn POWER switch on to reset the amplifier. 6.
