traced to high-frequency interference, but unless there is a loudspeaker in the system that might unexpectedly burst into hard rock music from the nearby radio station, it is common for engineers to overlook this source of inaccuracy and blame the manufacturer of the amplifiers or data converters...
89-Amateur-Radio-Amplifiers (http://forums.qrz.com/forumdisplay.php?89-Amateur-Radio-Amplifiers)Lots of ham still utilize high power vacuum tubes in their final amplifiers. Often heard that there are few companies actually building new vacuum tubes theses days, maybe just Russia and China of ...
IMPORTANT!: If you want to connect an amplifier to this exciter please first make sure that output power is set correctly and does not exceed maximum allowable input power of the amplifier. See appendix for additional tips on connecting amplifiers and consider using a small 1-2dB attenuator. ...
