It can connect to the computer via RS-232 for control if you want to. The TenTec 538 Jupiter is a stand-alone radio. I need to know the really dumb stuff like does it have to be hooked up to a computer ALL the time, or just when you’re setting it up? Can you help? I know less still, and virtually nothing about SDR. It is being held in the second-hand section of a dealership that doesn’t usually carry Ten Tec equipment and therefore doesn’t know much about it. I was drawn to your site because I have been offered a 2nd hand Ten Tec Jupiter 538 if I can get the money together by Saturday afternoon. In our conversation we spoke of many features of the radio which may be of use to owners.Īs shown below, Paul’s words are in block italics. Over the past decade, Ten-Tec has come out with several firmware upgrades for the Jupiter, adding features such as AM, transmit roll-off frequency control, 60-meter operation, and (with a hardware modification), a CW receive capability plus the ability to plug in a PS-2-type keyboard for CW transmit capability. The Jupiter is an early example of “software-defined radio,” meaning that critical processing steps are done in the rig’s firmware rather than with hardware dedicated to specific tasks such as demodulation.
This great rig has been in their lineup for over a decade and was discontinued only recently. Paul, GM4ULS, and I exchanged several emails in August, 2013, about the Ten-Tec Jupiter, which Ten-Tec lists as their Model 538 HF transceiver.
