[TenTec] Audio improvements on Argonaut VI

[Greg S]

Carlos-
It is very interesting, the differing opinions between operators on this subject. I think the other fellows who have commented have given some good ideas on headphones. I think my Argonaut VI has the best received audio of any rig I have ever used.... and I have owned over 80 different HF rigs over the past 20 years. I hope you can give your Argonaut 539 another go. Yes, there can certainly be some "digital artifacts" heard in the audio while turning the VFO. The 539 is certainly not alone there. But your Corsair doesn't. It is a MECHANICAL VFO. (That occasionally needs maintenance.) I operate my Argonaut VI like many of my older , mostly analog rigs. Increase the AF gain, and "drive" with the RF gain. Seems to work for me. Hope some of our comments help you re-evaluate your 539.

 Hi,
 
 I just bought an Argonaut VI and got
 disappointed with the received audio
 (when comparing it with a Corsair II).
 
 When monitoring with headphones it
 improves a lot, but there is some hiss
 in the background, even without antenna
 and the RF gain all the way to the
 left.
 
 Do you guys think that I might have a
 damaged audio amplifier? Is there an
 easy way to improve the received audio
 with the in-built speaker? PBT/BW/NR
 settings are OK, I even performed a
 factory reset.
 
 Using headphones, I can hear a weak
 pulsing noise when rotating the
 frequency encoder. Is there a way to
 eliminate that ?
