Ultimate CB Radio – 43AX05

I have become interested in building the ULTIMATE CB RADIO – 43AX05 This based on an existing CB Base Station I have already that works well on TX & RX. The ubiquitous Uniden PC-122 Yellow Dotted HYBRID Icom IC-701 Building the ULTIMATE CB RADIO (43AX05) from my Uniden PC-122 Mobile CB radio built into an ICOM IC-701 Ham radio with all interior components removed.

Scanner Data Decoding by Discriminator output

Discriminator output Decoding from Radio Frequency Scanners. The Discriminator output from a scanner is the raw, unfiltered signal that a scanner produces before it is sent to the audio stage for output through the speaker — also called the “baseband audio.” This discriminator source is required for applications such as Trunker, T4Win, UniTrunker, and DSD. Most scanners must have a simple modification made to them to feed the discriminator output to Data Slicers, or in the case of UniTrunker, a soundcard. Note that for providing a signal for ACARS decoding, a connection from an earphone or speaker output is all…
