The ALT-512: A new general coverage QRP transceiver

There’s a new QRP transceiver on the market: the twelve band ALT-512 by Aerial-51.

At first glance, you’ll see a similarity between the ALT-512 and the LnR Precision LD-11/Aerial-51 SKY-SDR. The LD-11 and SKY-SDR, are very similar, save the LD-11 is marketed to North America (via LnR) and the SKY-SDR to Europe. The SKY-SDR had several iterative upgrades, most importantly the dual-threaded software used in the firmware, which cut CPU latency in half. Both the LD-11, SKY-SDR and now the ALT-512 are made in Europe.

According to Aerial-51, the new ALT-512 is built on the LD-11/SKY-SDR platform, has the same chassis design but has many improvements over the SKY-SDR:

  • 4m Band
  • 2.4 in. Color Display
  • Improved receiver pre-amplifier
  • 2 transistors in the transmitter PA (was 1)
  • Waterfall in addition to the Pan-Adapter Bandscope
  • 4 additional front-panel buttons
  • User friendly front-panel adjustment of often used parameters (formerly embedded within the software menu)
  • FULL TS-2000 command set implementation
  • Built-in Sound Card; Digi Modes run using only one USB-2 cable connected to the PC. No additional hardware required.

If the ALT-512 performs as well as or better than its predecessor, it’ll certainly be a great little QRP radio and an excellent general coverage receiver for HF broadcast listening.

Pricing has not yet been posted, but Aerial-51 plans to make this transceiver available in the next few weeks.
