Find the excitement of High HF band!
28MHz ALL-MODE MOBILE TRANSCEIVER
The easy and smooth operation of DX-10 is inherited from popular Alinco amateur radio equipment series such as a large back-lit display, excellent transmit/receive audio, SSB modes, 6 banks with up to 60ch memories each, Dual-watch, Scanning, SWR meter, key-lock and more and more at No extra costs!
Alinco DX-10 features:

- Channelized, with “fine tune” Clarifier frequency adjustment
- Antenna Impedance: 50 ohms, unbalanced SO-239
- Frequency stability: plus/minus 1 ppm
- Microphone Impedance: 2 kilohms
- Built-in Time-Out Timer (TOT)
- Switchable S/RF Meter
- Power supply requirement: 13.8V DC plus/minus 15 percent (11.7 to 15.8V DC)
- Operating Temperature: Negative 22 degrees F to 122 degrees F
- Supply polarity: Negative Ground
- Current drain: Transmit 6A, Receive 750mA (maximum) 350mA (Squelched)
- Dimensions: (approximate.) 6.7 in. (w) x 2.04 in. (h) x 8.4 in. (d)
- Weight: 3.09 lbs. (1.4 kg)
The DX-10 covers the entire 10 meter band and operates on USB, LSB, CW, AM, and FM. RF power output is 25 W for SSB and 12 W for CW, AM, and FM. There is no subaudible tone function or split transmit/ receive feature for FM repeater operation.
The radio has power supply polarity and SWR protection. Current consumption is 6.5 A maximum, requiring a modest dc supply. Included accessories are the Alinco EMS-70 hand microphone, microphone clip, mobile mounting bracket, and mounting hardware.
The DX-10 uses an unusual frequency tuning arrangement. The radio has six memory banks that are preprogrammed at the factory, with each bank covering a span of 300 kHz using 60 memory channels. The banks are selected by the A B C D E F switch on the left side. Channels are spaced 5 kHz apart. For example, memory bank A covers 28.0 to 28.3 MHz, with CHANNEL 01 equaling 28.000 MHz and CHANNEL 60 equaling 28.295 MHz. A separate CLARIFIER knob adjusts the fine tuning of the frequency of each channel ±10 kHz in steps of 10 Hz, 100 Hz, 1 kHz, or 10 kHz. This tuning arrangement is much different than continuous tuning accomplished with a single knob, as found on virtually all other conventional amateur transceivers.
Front panel push button functions are: FUNC (function), RB/BP (roger beep/beep), NB/ ANL/LOCK (noise blanker/lock), DW/LCD OFF (dual watch; select another frequency to be monitored and the receiver switches between the two/display off), SCAN/SC LIST (scan/scan list), +10 kHz/HI-CUT (bumps the receiver up 10 kHz/high cut audio filter to reduce hiss), COL/TOT (display color/time-out timer), EMG/S/RF (switch to user-selected emergency channel/meter function). From left to right, the knob controls are memory banks A – F, mode, VOL/SQ (volume/ squelch), ECHO/TONE, RF GAIN/RF PWR, CLARIFIER, and CHANNEL.
In addition to the front panel controls, the DX-10 has a menu for 16 parameters such as microphone gain and sidetone level. Enter the menu setup by pressing and holding the FUNC button for 2 seconds. Then press FUNC repeatedly to select the desired parameter. The user has 5 seconds to rotate the CHANNEL knob to adjust the parameter. The display reverts to the tuned frequency in 5 seconds after a change is made.
ARRL Lab testing revealed some good results and some not so good. Let’s start with the good. Overall receiver sensitivity is very good. The two-tone third-order IMD dynamic range is only 73 dB at 20 kHz spacing. That’s not as good as recent multiband transceivers…. more
NO TRADITIONAL VFO, all frequencies are pre-stored in memory with adjustable fine tuning to fully cover the entire band.
