That's right. I've fixed in svn. > Second, in what applications are multiple receive and transmit channels > are used? They aren't used in tunnel.py right?

However, because I was a lazy bum, I didn't add the conditionals that distinguish between TX_SINGLE and TX_DUAL. You'll need to add the appropriate `ifdef TX_EN_0 and TX_EN_1 gating in usrp_std.v. [Please send a patch.] And send your new config file too. I assume it's going to be usrp_std_config_1rxhb_1tx.vh Thanks, Eric _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
