RF demodulators give you the raw signal like a stereo without a graphic equaliser,........
" It is more accurate than most talk-back systems because it samples the AM audio after it has passed through the AM circuitry of your CB radio"
demodulator audio is not how it sounds when listened to over the air on a radio with its agc + RF & audio filtering,
10-20 wraps of wire around your coax, germanium diode and some headphones is all you need.
Regular headphones seem to work well. Only issue i have had was when using a .010-.001 capacitor to roll off the high frequencies. Every time I add a cap the impedance miss match was horrid. Using the diode only the quality was decent!It would take high impedance headphones like the old crystal type to get much volume and even then it would be hard to hear yourself over yourself. the frequency response of those old crystal headphones wasn't the best either.

Incoming Region Produces X3 Solar Flare |
May 15, 2024 @ 14:55 UTC |
Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned |
