Hello all, I am about to attempt to dabble in the GNURadio/USRP World, and am primarily interested in the HF ham bands. More specifically for PSK operations. To further that effort, I am curious if, as with the BasicRX and BasicTX daughtercards, I would still have to construct some sort of external filtering, RF frontend, and pre-amplification circuits with the LFTX and LFRX boards. Or, can they be used directly, with all selectivity, filtering, and frequency selection done with GNURadio S/W? Thanks folks. Lots of interesting things going on here. Sam. -- View this message in context: http://www.nabble.com/USRP-Daughtercards-LFTX-and-... Sent from the GnuRadio mailing list archive at Nabble.com.
