WA3RNC TR-45L QRP Transceivers Are No Longer Available To Order

Standard Version TR45-L	TR-45L "Skinny" Version

Both versions have identical circuitry and PC boards. Both have an internal speaker. The standard version has the speaker on the left side panel. The “Skinny” speaker is on the rear panel.

• The TR-45L is a 5-band 5-watt CW transceiver covering the 80-75, 40-, 30-, 20-, and 17-meter bands.
• Full band coverage is provided, with the transmitter optimized for the CW band portions.
• The receiver is provided with both narrow and wide band IF filters, and CW and SSB detectors.
• Precision optical encoder utilized for long-life smooth tuning.
• An illuminated front panel meter shows “S” units on receive, and power output (forward or reverse) while transmitting. The meter also will display the battery state of charge.

• A “High VSWR” warning indicator will illuminate if the SWR exceeds about 2:1.
• The transmitter output is adjustable from a few milliwatts to 5-watts with a front panel control.
• RIT is provided to adjust the receive frequency up to + or – 5kHz from the transmit frequency. An amber warning LED is provided to show when RIT is active.
• Two VFOs for each band are provided with recallable memories.
• A built-in mode-B iambic keyer is adjustable from about 5 wpm to 45 wpm with a front panel speed control.
• Dual keyer memory messages record and playback. Each message has a 25-word (PARIS standard) storage depth.
• Separate straight key and keyer paddles inputs are provided on the front panel. Both can be connected and used with no switching required. Always ready for SKCC contacts…
• A front panel adjustable notch filter is provided to null out interference.
• A front panel RF gain control is provided.
• Operates from a nominal 12-volt power source requiring up to 1.7 amps on transmit, and about 120 ma on receive. An on-off switch is provided.
• Tuning speed is easily settable from 1 Hz to 1kHz per step with 64 steps per revolution.
• A selectable dial lock is available to prevent inadvertent frequency changes.
• A built-in speaker provides more than adequate volume.
• There is a knob or switch for every function – no confusing back menus!
