    1. My 4th Argonaut. They keep getting better.

      Posted by Carl on 18th Nov 2014

      I have had my Argonaut 6 for a bit over a week now. I have participated in 2 sprints. I learned to use it via the front panel first. It was easy to get the hang of it. Then I ran it with N4PY software. If felt and sounded like my Eagle via the software. It behaves well with my LP-Pan-2 panadapter and NaP3 software. I can go simple or complex. It plays well. It is everything I had hoped for. So 505, 509, 516 and now a 539...a nice line-up.

    2. Amazing box

      Posted by Haney Howell on 20th Aug 2014

      The Argonalt 6 is like going back to the future. I purchased a 505 qrp rig in Denver in 1979 and placed it next to my Drake C line. I could not believe the quiet receiver. I still have the Omni D I purchased soon after along with an Orion and Corsair.31.

      It now appears that Ten Tech has brought back much of the early magic while using the new technology. For an old ham (since 1958). it's the best of both worlds. An amazing box that's easy to master. I've worked 50+ countries in just a couple of weeks, and constantly get great review on the SSB audio. I purchased the 6 kc filter and glad I did.

    3. More Value than the Price Suggests

      Posted by Jim KM5M on 21st Jul 2014

      As with all Ten-Tec purchases, the Argonaut VI delivers much more value than the price suggests. It's a high-performance American-made QRP transceiver in a very compact package. Not having quite the "street appeal" of the Argo V, the smaller Argo VI sports an improved user interface. The receiver is HOT, QSK is PERFECT, and receive audio is THE BEST. The only additions might be CW memory, a jack for relay keying a tube-type amplifier, and a speaker jack. I look forward to a long and happy marriage with my Argo VI, as I've had with my other T-T rigs. Every one is a keeper.

    4. Argonaut 6

      Posted by Ron Davidson on 17th Jul 2014

      Wow! What a receiver. I also have an Omni V, and the Argo 6 runs rings around it. Fun to operate and easy to use.

      Now, I wish the 418 amp would go on sale!!!
