Ten-Tec Model R4020, 40 & 20 Meter Dual Band QRP CW Transceiver New in Box

This transceiver was purchased by a Ten-Tec collector and was never opened or built.

It is in the original box with the instruction manual.

Description:

The Ten-Tec R4020 is a popular, compact, two-band (40 & 20 meter) QRP (low-power) CW (Morse code) transceiver kit, known for its great field performance, good audio, sensitivity, and features like RIT, attenuator, CQ caller, memory, and selectable filters, making it ideal for Parks on the Air (POTA) or SOTA, often praised as a great value despite lacking some modern features like AGC. It runs on internal batteries or an external 9-12V supply, delivers around 5 watts, and is highly recommended for portable operations, say users on Q R P e r.

Key Features & Characteristics:

Bands: 40m & 20m.
Mode: CW (Morse Code).
Power: ~5 Watts QRP, battery-operable.
Controls: VFO tuning, AF Gain (side tone volume), Attenuator (strong ~30dB), RIT (Receiver Incremental Tuning).
Display: LCD showing frequency and other info (full frequency displayed, which is a plus).
Filters: Selectable CW filters (e.g., 400Hz, 900Hz) for good selectivity, plus wider for general listening.
Convenience: Built-in CQ caller (paddle-activated, sends CQ + call sign) and memory storage.
Design: Compact, portable, but knobs protrude; audio often best with headphones.
Build: Made by UK Kits for Ten-Tec.

Why It's Popular:

Excellent Value: Offers rich features for its low price point.
Field Ready: Great for portable activations (POTA/SOTA) due to size, battery operation, and good performance.
Superb Audio: Users praise its sensitivity, low noise floor, and audio fidelity, making weak signals audible.
