Mandated by regulation as a low power device, the range on these radios is much greater when combined with a signal amplifier, or “Linear” Amp. It is not advocated using a linear amp, however for the most part, enforcement of the restrictions are few and often only when an illegal ...

Well in reality it tries to trick your radio or amplifier into thinking everything is perfect. Meaning the Antenna system has the same impedance (usually 50 ohms) as the radio antenna output (so239). That way the radio or amplifier can not worry and send full power down the transmission ...
- Hallicrafters HT-30 exciter, HT-31 linear amplifier, and SX-96 receiver - Central Electronics 10B and 20A exciters, plus receiving adapter - Lakeshore Phasemaster Junior transmitter Now I grant that these rigs weren't inexpensive, and that there was a far wider selection of AM gear. But ...
and still do a good job of preventing signals 20 kHz and 40 kHz removed from the desired signal from encountering an amplifier or second mixer that might introduce nonlinearity. Many manufacturers adopted an up-converting architecture with a first IF above the signal frequency, allowing for cheaper...
For the simple purpose of linear amplifier testing, perfect sine waves are not required; this note on distortion is merely for reference in case it is needed for a different application. The circuit consists of an op amp oscillator and three buffers. The gain is set by Rg and Rf; we ...
TurnAFCback on and peak the signal withFINE TUNE. While switching the signal generator step attenuator over three 10 dB steps, adjust M5 and L1 for best accuracy over the 20 dB meter range. L2 and L3 also affect accuracy by changing the IF amplifier operating point. If necessary, adjust ...
