10m and 12m transceivers: maximum performance on the HF bands
Discover the power of the 10-meter and 12-meter bands with our high-quality transceivers, specially designed for radio amateurs who want to get the most out of their transmissions. These bands belong to the HF frequency range and offer surprising possibilities for long-distance communication – especially during favorable propagation conditions.
Whether you're just starting out or have been an active radio amateur for years, a good 10m or 12m transceiver provides you with a versatile piece of equipment ready for connections all over the world.
Why choose a 10m or 12m transceiver?
- Worldwide communication in good ionospheric conditions
- Compact and powerful: ideal for home or portable use
- SSB support (USB/LSB) for efficient voice transmission
- User-friendly: also suitable for novice radio amateurs
- Perfect for experimenting, DXing and contests
What makes these tires so interesting?
The 10-meter band (28,000–29,700 MHz) is known as the "Magic Band" due to its unpredictable nature and enormous range during active sunspot cycles. The 12-meter band (24,890–24,990 MHz) – one of the WARC bands – offers stable daytime performance and is ideal for those looking for that little bit of extra flexibility between 10m and 15m.
Both bands are well suited for single-sideband modulation (SSB) and are used worldwide by radio amateurs for contests, DX traffic and propagation experiments.
Who are these transceivers suitable for?
Our 10m and 12m transceivers are perfect for radio amateurs, DXers, and DIYers who want targeted communication on these popular HF bands. With brands like Yaesu, ICOM, Kenwood, CRT, Anytone, Alinco, and President, you're guaranteed reliability, excellent audio quality, and intuitive operation.

What is SSB and how does it work?
SSB stands for Single Sideband and is an efficient way to transmit voice over radio. Instead of transmitting the full AM signal (which transmits both the upper and lower sidebands, as well as the carrier), SSB uses only one of the two sidebands – the Upper Sideband (USB) or Lower Sideband (LSB). This halves the required bandwidth and requires less transmit power to send a clear signal.
USB or LSB? What you need to know
In SSB, a fixed distribution is usually maintained:
- LSB (Lower Sideband) is used as standard on the lower HF bands below 10 MHz – such as the 160, 80 and 40 meter bands.
- USB (Upper Sideband) is common on higher HF frequencies, such as the 10, 12 and 15 meter bands.
This distinction is important for correct communication between operators. If transmitters and receivers use different sidebands, they cannot understand each other.
Why SSB is so popular among radio amateurs
- Efficient use of spectrum: SSB uses less bandwidth than AM.
- Economical in power: With less output you reach greater distances.
- Ideal for long distance communications (DX): Especially during favorable propagation.
- Widely applicable: From amateur radio to maritime and aviation communications.
Please note : This always requires precise antenna adjustment.
A minor disadvantage of SSB is that it's more susceptible to interference, and the signal requires precise tuning. Even the slightest shift can make a conversation sound unclear. Modern transceivers help with this with digital filters and fine-tuning knobs.
Applications of SSB
- SSB is used worldwide in:
- Amateur radio (HF communications)
- Maritime communications (such as on the 2182 kHz distress frequency)
- Aviation (for overseas flights on HF)
- Military radio communications
Fun fact
The choice to use USB on higher frequencies and LSB on lower frequencies was made without any technical necessity – it was essentially a kind of agreement (arbitrary). This division was later adopted worldwide so that everyone uses the same format. This prevents confusion and allows you to easily communicate with other radio amateurs, anywhere in the world.
