Understanding Ham Radio Bands


Ham radio bands are portions of the radio spectrum allocated for amateur radio use. Each band corresponds to a specific range of frequencies, typically identified by wavelength in meters or by frequency in megahertz. Lower frequency bands have longer wavelengths and tend to travel farther, especially at night, while higher frequency bands often allow for local or line-of-sight communication with less interference.

The characteristics of a band are shaped by several factors:

  • Wavelength: Longer wavelengths travel farther and bend around obstacles better.

  • Propagation: How signals reflect, refract, or are absorbed in the atmosphere.

  • Time of Day: Some bands work best during daylight, others at night.

  • Solar Activity: Higher solar activity can enhance high-frequency propagation.


160 Meters (1.8 – 2.0 MHz)

How it works:
Known as the "Top Band," 160 meters behaves like the AM broadcast band. Signals can travel hundreds of miles at night through groundwave and skywave propagation, but daytime range is usually much shorter due to absorption by the ionosphere.

Best for:

  • Long-distance nighttime communication.

  • Experimental antennas and low-frequency propagation studies.

When to use:
At night for regional to continental contacts, especially in winter when static is lower.


80 Meters (3.5 – 4.0 MHz)

How it works:
A strong nighttime band with excellent regional coverage. During the day, it is mostly limited to short-range contacts due to ionospheric absorption.

Best for:

  • Nighttime nets and ragchewing.

  • Emergency communications covering a few hundred miles.

When to use:
Evenings and nighttime for stable, reliable communication.


60 Meters (5.3 MHz)

How it works:
This is a shared band with specific channels and power limits. It often bridges the gap between 80 and 40 meters, working well for medium-range contacts both day and night.

Best for:

  • Emergency communications.

  • Consistent regional coverage.

When to use:
When 80 meters is too noisy or dead during the day, and 40 meters is too long-range for your needs.


40 Meters (7.0 – 7.3 MHz)

How it works:
A versatile band with excellent regional coverage during the day and long-distance capability at night. Often considered the "workhorse" of HF.

Best for:

  • Daytime communications over a few hundred miles.

  • Nighttime DX (long-distance contacts).

When to use:
Day for regional nets, night for chasing distant stations.


30 Meters (10.1 – 10.15 MHz)

How it works:
Primarily used for digital modes and CW (Morse code). It offers stable propagation nearly all day and night with low noise levels.

Best for:

  • Long-distance digital and CW contacts.

  • Quiet band for low-power operations.

When to use:
When other bands are noisy or crowded, especially for digital modes.


20 Meters (14.0 – 14.35 MHz)

How it works:
The most popular DX band. Signals travel worldwide during daylight and into the evening. Propagation is influenced by solar activity.

Best for:

  • Worldwide communication.

  • DX contests and expeditions.

When to use:
Daytime for global contacts; remains open later during high solar activity.


17 Meters (18.068 – 18.168 MHz)

How it works:
A quieter band with less congestion. Offers good long-distance propagation during daylight hours and is less affected by contest activity.

Best for:

  • Relaxed long-distance contacts.

  • Avoiding heavy competition for contacts.

When to use:
Daylight hours, especially during solar peak conditions.


15 Meters (21.0 – 21.45 MHz)

How it works:
Excellent DX potential when the solar cycle is favorable. It can open early and stay active through the afternoon.

Best for:

  • Worldwide contacts with small antennas.

  • High-energy contests and pileups.

When to use:
Late morning to late afternoon during active solar conditions.


12 Meters (24.89 – 24.99 MHz)

How it works:
Similar to 10 meters but slightly more stable. Offers great DX when propagation is favorable, often with less noise.

Best for:

  • Daytime DX.

  • Experimenting with small portable antennas.

When to use:
Daylight hours during solar peaks.


10 Meters (28.0 – 29.7 MHz)

How it works:
When the solar cycle is strong, 10 meters can provide worldwide communication using very little power. At solar minimum, it works mostly for local and regional contacts.

Best for:

  • DX during solar peaks.

  • Short-range communications at other times.

When to use:
Daytime during high solar activity for DX; local use otherwise.


6 Meters (50 – 54 MHz)

How it works:
The “Magic Band” that can act like HF or VHF depending on conditions. Sporadic-E propagation can allow long-distance contacts unexpectedly.

Best for:

  • Surprise DX openings.

  • Local communication when HF is poor.

When to use:
Late spring and summer for sporadic-E; local year-round.


2 Meters (144 – 148 MHz)

How it works:
Primarily line-of-sight VHF communication, but can reach farther via tropospheric ducting. Common for FM repeaters, simplex, and satellites.

Best for:

  • Local and regional voice communications.

  • Emergency response and public service.

When to use:
Any time for local contacts; watch for rare tropospheric openings.


1.25 Meters (222 – 225 MHz)

WOUXUN KG-UV9D Plus — Full in-depth review (7-band coverage including air band)

The WOUXUN KG-UV9D Plus sits in the category of affordable, feature-rich handheld transceivers aimed at hams who want more than the usual dual-band radio. It’s one of those radios that advertises "multiband" capability without pretending to be a professional base rig — the idea is to give radio hobbyists a lot of receive coverage, solid transmit on the amateur bands, and a handful of useful extras like dual receive, memory channels, and a user-friendly form factor. This review walks through the KG-UV9D Plus from design and audio to RF performance, usability, and who should consider buying one.

Exterior, ergonomics and construction

The KG-UV9D Plus strikes a balance between compactness and control. The case is slightly larger than the smallest HTs, which is a good thing here: there’s room for a more generous speaker, a larger display, and sensible button spacing. The front panel layout is logical — a central channel/volume knob, a decent-sized display with backlight, directional buttons, and a row of programmable keys. The keypad is tactile and usable with gloves, though the rubberized keys collect dust over time.

Build quality is respectable for the price. The housing is ABS plastic with a textured finish. It feels robust in normal use, though it’s not an overbuilt mil-spec unit. The antenna connector is a standard SMA or SMA-female type (depending on the market), and the battery locks in tightly. Expect a radio that will survive pocket drops and field use but treat it with care around water and hard impacts.

Display and user interface

The display is bright and clear enough for quick reads of frequency, mode, and battery. Menu navigation is straightforward: short presses for main actions, long presses for secondary functions. The KG-UV9D Plus exposes a fair number of functions without forcing you into deep menu dives, and programmable keys let you keep the features you use most at your fingertips.

Menus are a little dense compared with premium rigs, and the manual menus can be slightly inconsistent in terminology. If you’re patient and willing to learn the button combos, the UI becomes second nature quickly. For many users, desktop programming software will be preferable for initial channel setup.

Receiver coverage, including air band

One of the headline features is wide receive. The radio typically covers multiple bands enabling monitoring of broadcast FM, public service frequencies in many regions, shortwave slices, and the aviation VHF band for listening to aircraft traffic. For people who want to listen to air band transmissions, the KG-UV9D Plus can be a fun little monitor. Important: for aviation communications, this is a receive capability only — transmitting on aviation frequencies is illegal and dangerous unless you hold the appropriate licenses and equipment approvals.

Receiver sensitivity and selectivity are very good for a handheld in this price bracket. Weak signals come through with good clarity, and the AGC behavior is acceptable. On crowded VHF/UHF amateur repeaters and simplex channels, the receiver filters handle adjacent signals reasonably well, but you won’t get the narrow, sharp filtering of higher-end rigs. Squelch and tone decode (CTCSS/DCS) work as expected and help with noisy repeater environments.

Transmit performance and power

Transmit power is typical for an HT: selectable low, medium, and high power levels. On high you’ll get the sort of output that will work well for local simplex and repeaters when you’re in town or on a hilltop. Antenna matching is important; using a decent stubby or aftermarket antenna makes a surprisingly large difference in both transmit reach and receive quality.

Audio, speaker and microphone

The speaker is larger than small cheap HTs and puts out clear voice audio with good midrange presence. Clarity at moderate volumes is excellent for decoding weak repeater audio and listening to air band transmissions. Microphone quality is also good for everyday use — voices sound natural and intelligible into local repeaters. There is often an adjustable microphone gain setting, which helps with handheld to mobile transitions if you switch to a different mounting setup.

Battery life and accessories

Battery capacity is competitive for the class. With periodic use and moderate transmit duty, you’ll get a full day of typical operation. If you do heavy transmitting (for example net control or long ragchews) battery drain accelerates — consider carrying a spare battery or using a higher-capacity aftermarket pack for extended outings. The package includes a charger, belt clip, and programming cable. Aftermarket accessories such as better antennas, speaker mics, and extended battery packs are widely available and worth considering if you want improved performance.

Programming and memory features

Channel memory, CTCSS/DCS, programmable scans, priority channels, and dual watch are all present. The radio supports memory groups and has enough individual channel slots for most casual to intermediate users. PC programming software speeds setup dramatically and is recommended unless you enjoy entering frequencies by hand on the keypad. For net operators, the scanning behavior and priority channel options are helpful.

Durability, reliability and real-world use

In everyday use the KG-UV9D Plus is dependable. Many owners report years of satisfactory service with routine care. It’s not waterproof unless specifically specified, so avoid extended exposure to rain. The radio tolerates vibration and temperature swings common in field use, and the battery contacts remain reliable over time.

Who should buy the KG-UV9D Plus?

Limitations and tradeoffs

  • It is not a high-end transceiver and does not have the advanced filtering, front-end protection, or transmit linearity of premium handhelds.

  • Menu structure and user labeling are occasionally confusing. If you’re impatient with button combos, programming with a PC is almost mandatory.

  • Waterproofing is typically limited; don’t rely on it for heavy marine or wet-weather use without protective measures.

  • For users needing extended transmit range, a mobile rig or higher-power setup will outperform any handheld.

Final verdict

The WOUXUN KG-UV9D Plus delivers a surprising amount of capability for its price. It’s not pretending to be a pro rig, but for amateur radio enthusiasts who want a versatile, easy-to-use handheld with wide receive coverage (including aviation monitoring), reasonable transmit power, good audio, and solid battery life, it is a compelling option. It shines as a daily driver for local communications, emergency preparedness kits, and portable adventures. If your priorities are top-tier sensitivity, military-grade durability, or professional filtering, consider stepping up in price. But if you want a lot of features for the money and a radio that’s useful right out of the box, the KG-UV9D Plus is worth a close look.
