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. The PC-122 LED meter has been interfaced into the Icom IC701 large analogue meter and adjusted to read correctly. The Yellow Dotted PC-122 is a great performer with the Kenwood MC-85 Microphone which is a direct…
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…
DDRR Antenna for 40 Meters Ham Band Lesson for CB
A 40-10 Meter DDRR Antenna – a Lesson for Hams and CBers – Vertical & Horizontal Polarity. ‘DDRR’ means “Directional Discontinuity Ring Radiator” antenna See CQDX11.com for my other articles on CB DDRR Antennas HERE. This article was one of a few that gave me the impetus to build and design my own DDRR! CB Radio DDRR HERE -1.1:1 SWR 56 Ohms impedance – 12 ” high – 104″ long Copper cable – 8″ gap & 8″ tap from upright along radiator. Its like a joke but it WORKS like a 9′ S/S Quarter Wave Whip!!      This antenna consists of a…
