The LimaSDR selfmade transceiver

In January 2014 I build a LimaSDR Transceiver for all shortwave bands. It works with PowerSDR Software. You need a very good sound card for this transceiver. I need four weeks to finish the transceiver.

Frequeny: 250 kHz to 30 MHz
Output: Lower bands 2-3 Watt upper bands 1 Watt.

Tha costs was:
100€ parts
30€ Case and knobs
40€ Low pass Filter
15€ Cable

The LimaSDR transceiver works great. But you need a really big computer and a very good sound card to use it good. It was a lot of fun to build the transceiver. But I’am a fan from old heavy radios. I miss the knobs on a SDR transceiver. I think about to sale the Lima.
