[VK2TPM] Generating RF with an osmo-fl2k VGA dongle
marxy's musing on technology /////////////////////////////////////////// Generating RF with an osmo-fl2k VGA dongle Posted: 30 May 2018 11:55 PM PDT http://blog.marxy.org/2018/05/genera...ga-dongle.html I've continued to play with the cheap ($10) USB VGA dongles which can be used as a fast digital to analog converter. Working with Ross, VK1UN, we've been climbing the learning curve ofÂ* GNURadio Companion to generate the samples we need to transmit modulated RF. The fl2k_file command line tool needs a file with 8 bit signed samples. These are clocked out at 100M samples per second by default. |
