"Any Band" Direct-Conversion SSB/CW Receiver Kit, No enclosure Regenerative 4-Band SWL Receiver Kit, includes front panel, no enclosure. Universal Low-Noise Broadband RF Preamp Kit, Untuned It certainly can provide more than QRP output levels if conditions warrant.Click on the small picture for a larger one (if available)Ĭlick on the Model Number for a SPEC sheet As I plan to use the rig for QRP this is mostly academic. I found that into a 50ohm dummy load I could generate up to 40w output for 80m, 35w output for 40m, 30w output for 20m and so on, down to about 15w output on 10m. This results in differing output wattage dependent on antenna resistance and frequency. If you're going to run QRP then no worries because you won't be running the power input up to a point that could trip the final, Maximum input power is marked by the thick line on the Input Power meter (about 70w). The SWR will affect how much output drive you can use. Unfortunately this can't necessarily be done into a dummy load unless you're match is near 1:1.

After you're matched up you can bring the power up to where you want to operate.

Better yet use a frequency analyzer to tune QRM free.

Find and open frequency (wait, listen, wait again, listen) and while holding the Set Drive button apply just enough power using the Drive knob to give you some RF out for matching your antenna.

Turn the radio on by pushing in the RF Gain knob (it is the on-off switch).

Turn the Drive knob down (counter clockwise), select your band.

I spoke with a ham I work with who has rebuilt one and he said it's not difficult, simply time consuming (but he repairs electronics all day so YMMV).

It doesn't slip (yet) but it's kinda stiff so I expect a PTO rebuild to be in my future. The Ham I purchased mine from said it had been rebuilt. From web searches and reviews its most common problem is a PTO that has to be rebuilt every few years. It also has easy band changing and nice filtering. This resulted in a simplified design and good selectivity but without the IF there is no AGC so be ready to work those RF/AF gain knobs. It doesn't use a superheterodyne receiver but a direct conversion receiver (Ten-Tec called it a double direct conversion receiver). It has a built-in power supply that runs off 115-120v mains.

It doesn't require fiddling with a resonant tank circuit of the typical tube radios of the era to work out resonance. In the simplest sense it was an ideal radio for the Novice Licensed HAM operator of the 1970s.

The Ten-Tec Century 21 is an interesting transceiver.
