Argonaut V
IF-DSP QRP Transceiver

An IF-DSP software-defined radio for QRP!

Announcing the new Ten-Tec Argonaut V IF-DSP HF 20 watt transceiver. Another innovative software-defined radio from Ten-Tec. Argonaut V has the benefits and features of IF-DSP, in a modern 20 watt HF transceiver. Our philosophy is that "low power" need not be synonymous with "incomplete". Some low power rigs offer pieces as options. DSP as an option? Not with Ten-Tec. Some offer limited performance and features. With the new Argonaut V, we offer solid HF radio performance in a user-friendly format, competitively priced.

20 watts output power, all modes. SSB, CW and FM. Front panel adjustable from 1-20 watts output. AM operation at 5 watts carrier power (20 watts PEP). Metering measures forward or reflected power in switchable 2 or 20 watt scales.

A true general coverage all-mode HF transceiver. Receive .5 to 30 MHz continuous in user-selectable tuning rates of 10 Hz or 1 kHz. Transmit on all 9 HF ham bands 10-160 meters.

35 IF-DSP receive filters are built-in. No extra filtering to buy to operate any available mode!
Filters are 200 Hz to 1000 Hz in 50 Hz steps, 1000 to 2800 Hz in 100 Hz steps; 4 kHz and 6 kHz in AM. An additional 15 kHz filter is provided for FM mode operation. Shape factors all 1.5:1 or better.

This little rig is a PSK31 dream. No accessory boxes necessary. Simply connect audio cables from the audio in and audio out jacks to your PC sound card and you're on the air. That's right, no interface, no dropping resistors in the TX line - plug it into the sound card and get on the air. While already suitable for digital mode operation, a high stability TCXO and a rear heat sink fan kit are available as options.

Like other recent Ten-Tec HF transceivers, the Argonaut V is a software-defined radio. All functions and features of the rig are stored in Flash ROM. To add new features, simply visit our website, download the latest, and it's as if your rig rolled off the production line a few minutes earlier. Should the 60-meter band be allocated for amateur radio use, your transceiver will be ready the day the band opens.

Selectable metering functions. In receive, S-units. In transmit, selectable among 25 watt / 5 watt forward power scales, 25 watt reflected power scale, 1.0:1 to 2.5:1 SWR or collector current draw.

Band scan and memory scan. Memory scan has lockout feature for skipping constantly busy
frequencies. Band scan can be set to scan between two user-defined frequencies of any margin.
The operator can even program and scan memories for different modes.

CTCSS tone encode for 10 meter FM repeater access.

Heavy-duty cast zinc main tuning knob.

Variable CW transmit offset with tracking sidetone, adjustable 400-1000 Hz. Like all Ten-Tec rigs, Argonaut V is equipped with full QSK operation in CW mode. Built-in CW keyer with variable speed control, 10-50 WPM.

Argonaut V is equipped with a PTT hand microphone as standard equipment.
