[Hallicrafters] 50 KHz Signal generators (Audio)

[JM/CO]

Hertz is hertz. Doesn't matter where it comes from. Other considerations are
the output voltage, whether or not modulation is possible / required, and
the termination impedance of the generator. This is usually 50 or 75 ohms
for RF generators, and 600 for audio, sometimes higher, but hardly ever
lower.
