I'm exiting the hobby for the foreseeable future. The following Ten Tec items are offered for sale on this list before going to auction. A rough photo of the complete station is available on the QRZ.

Wow, that's quite a sanctimonious and back-handed compliment if I ever heard one. The SDR-1000 may very likely become a "dinosaur" sooner than you think. The SDR-1000 certainly produces some good pe

The primary limitation is their use of a single PC microprocessor to accomplish many parallel tasks. It's a commendable start -- but when Flex and other manufacturers develop an SDR architecture tha

That's correct. Part 97 regulates the type and emissions of radio links, but not the type of non-radio control. Nor do I see anything within Part 97 that addresses "positive control" of the link to

By comparison, the Omni VII is similar in price to the popular Icom Pro-III when one factors in the power supply and auto tuner and no optional roofing filters. Icom does not offer optional roofing

Ten Tec's TCXO is actually quite good. You may only need to re-adjust it one last time after initial aging. I also retrofited mine and its frequrncy did not vary more than about 10-20 Hz over time.

This makes perfect sense if the 6 kHz 1st IF filter is selected for both AM and SSB modes. In AM, the LO carrier set point is placed in the center of the filter's passband, leaving 3 kHz on each sid
