DDS-VFO
A 21st Century upgrade for the better CB transceivers of the era just past.
— No more SSB drift
— Scan
— VFO
My desire is to also add DSP to the RX side. (West Mountain hadn’t seen that on a CB, yet, and kindly offered circuit diagram advice).
Am in initial stage of putting this together (a DX-99V2 with a different board than earlier model shown in video).
Expect that price of parts & labor may come close to initial price of these radios years ago — but these radios now have years of use on them — so it’s sorta like an 5.0 Coyote into an older Mustang.
Goes well then a newer DX-959b is next.
DSP on TX side not needed as dynamic noise-cancelling mics are what these were designed to use. Internal DSP for RX removes need for external device, and should improve audio over integrated speaker.
Someone with a beloved C148 ought to also look into this. Used units of this type past specific brand are available if a suitable candidate can be acquired.
— This isn’t less expensive than a Q5/QT60 unless one can do all the work himself.

DSP Kit
*VIDEO* Italian DSP Kits Fit this into or onto an old favorite. (You techs fill in what fumble-thumbs like me won’t deduce from an analysis of this unit; size & reliability). Link is a good demonstration of effectiveness. DSP is the 11-Meter game-changer for mobile use on-highway. That one...

SKIP Problems in Noise Abatement.
The discourtesy of screwing up AM-19. The understood Truckers Channel. Got 39 to 119 other channels before we consider freeband. The thread is not to whine and moan, but to introduce others new to CB how to deal with Skip overwhelming local comms. The exigencies of the road. Your experience...
