So the current set-up is:
1). Wilson 2000 antennas on included 10” shafts on the Peterbilt mounts. The shorter whip, but 1.5”+ probably has to come off (to match 55” height) as antennas are on Hustler QD
2). Factory coax left alone.
3). Power run from BATT box with ANCOR 10/2 Duplex. Reduced to 12-ga at near end. POS fused at BATT.
Fat big ferrite toroid DC distribution box.
4). Ferrites for each power lead: radio & speaker.
5). Ferrites at each end of audio cable to speaker. (“Secured” lines to box with some zip tie deviltry before placing in console rear).
6). MORGAN SYSTEMS 411b BANDPASS FILTER from radio
7). RG8 jumper to PALOMAR ENGINEERS COAX FILTER
8). Radio is now the GALAXY 99v2 plus a ASTATIC 636L dialed in for it as done by Clays Radio Shop some years back.
Low Power: 02.25W, modulates 15W
High Power: 15.00W, modulates 30W
Compare this to
Eldorado828 super clean install in his KW 880. (President Walker thread). The 680 has the same cab and is greatly similar to this PACCAR sister. That’s the expected look.
But, heh-heh, THIS one has the coveted endless echo, robot voice and sooper-annoying Roger Bip. And big ol’ boomin’ Galaxy audio.
The Eldo may LOOK good, . . . but someone’s haulin’ cash, and someone’s haulin’ trash.
(Okay, worked that
red out of my neck).
Coax Box Filters are shown with covers removed in a post above.
Speaker now slid forward as lines shortened.
Re-check of DC power and antenna tuning with truckstop meter are next.
