| TX power | 4 / 12 W (4 watts AM (the legal CB limit) and 12 watts PEP on single-sideband, with a variable power-output control. The DX-959 is FCC Part 95 certified and license-free to operate at these levels; any modification beyond them is not legal on CB.) |
| Modes | AM, SSB (USB/LSB), PA |
| antenna | SO-239, 50 ohm |
| mic | Front 4-pin microphone connector (standard CB wiring) |
| ext pa | Rear external-speaker and PA-speaker jacks (for PA mode) |
| dc in | 13.8 VDC negative-ground vehicle power (fused red/black lead) |
| power req | 13.8 VDC negative ground (vehicle power). |
A full-featured 40-channel AM/SSB mobile CB at the legal 4 watts AM and 12 watts PEP SSB, with a five-digit frequency counter, a large illuminated four-scale meter, automatic SWR with a high-SWR alert, talkback, a roger beep, a clarifier, RF and mic gain, and PA mode. It has a good reputation for receive performance and a two-year warranty.
It is a standard-size SSB chassis, larger than an AM-only rig, with no FM and no weather channels. Audio is through the chassis speaker plus rear jacks rather than a fancier audio system, and the frequency counter can tempt out-of-band or over-power modification, which is illegal on CB.
The Galaxy DX-959 is a long-running, full-featured 40-channel AM/SSB mobile CB, distinguished by its five-digit frequency counter and large illuminated meter. It runs the legal 4 watts AM and 12 watts PEP SSB and includes automatic SWR, talkback, a clarifier and PA mode. For an operator who wants SSB and the full Galaxy feature set in a dashboard radio it is a standard recommendation; the cheaper DX-949 drops the frequency counter, while FM-equipped CBs are the choice for those who want the newer CB FM mode.
The Galaxy DX-959 is a long-running, full-featured 40-channel AM/SSB mobile CB radio for the 26.965-27.405 MHz citizens band. It is a genuine FCC Part 95 radio, license-free to use, and runs the legal 4 watts on AM and up to 12 watts PEP on single-sideband, with a variable power-output control. Its signature feature is a five-digit frequency display, which is what separates it from Galaxy's lower-cost DX-949.
Beyond the counter it carries Galaxy's full feature set: a large illuminated meter with four scales (signal strength, AM modulation percentage, power and SWR), an automatic SWR circuit with a high-SWR alert LED, variable talkback with its own volume, a roger beep, a receive clarifier for SSB, a noise blanker and automatic noise limiter, RF and mic gain, a three-position tone control, a dimmer, and a PA mode with rear speaker jacks. The antenna connection is a standard SO-239 and the microphone is a front 4-pin connector, and it runs on 13.8 volts of vehicle power.
Published receiver figures are solid for a CB: about 0.5 microvolts sensitivity on AM and 0.25 on SSB, with 65 dB image rejection and 60 dB adjacent-channel selectivity. It is a standard-size SSB chassis with no FM and no weather channels, and the frequency counter can tempt out-of-band or over-power modification, which is not legal on CB.
It remains in production, including display-color variants such as the DX-959B with a blue faceplate. The lower-cost Galaxy DX-949 is the same radio without the frequency counter, and the desktop Galaxy DX-2517 is its base-station sibling, though the 2517 is a 10-meter amateur radio rather than a CB.
