- I have a TenTec station Omni VII, Centurion, RX-320D, Model 715, and some of their receiver kits. I also have a pair of Palstar tuners, only one of which is on line with the transceiver right now. I

- Antenna "tuners" (matchboxes) do not really tune (resonate) an antenna -- they just match its impedance to the Tx or Rx. This is generally not very important at the sub-milliwatt power levels encount

- The Ten Tec Antenna Tuner Tuner kit is a noise bridge with a fixed 50 ohm reference to compare to the Antenna. It has an audio modulation inserted on the Noise signal to make the match point stand ou

- I may use it on the transceiver as you suggest... but what about what Charles says about not needing a tuner for a receiver (only.) Maybe on receiver-only it is a solution looking for a problem. I wi

- On events like Field Days, I have seen a tuner improve the signals some 3 dB, or maybe it was the combination of signal plus improvement in QRM, (lowering of the noise floor). For listening when the

- James, The answer is, it depends on the tuner, and the band conditions. Most tuners today simply match the SWR but don't really add any bandpass selectivity. However if you use a link-coupled tuner,

- Rick, DJ0IP, makes excellent points. The common ham tuners from the factories are Tee circuit here in USA, a high pass type, so no help against harmonics of your signal or another signal. The link co
