Hi Berndt, Thanks for code checked-in about the FT990 and sorry for the mispelling. This is right in time for the Hamlib 1.2.5 release. BTW, you made the same mistake I made couple of month ago, to post on discuss-gnuradio instead of hamlib-developer mailing list :-) No trouble on that, the Repl

You'll want to strip out the extra receiver. The default fpga is 2 rx and 1 tx. You probably don't need the second RX for your application. You also may not need the halfband filter on your receiver. In the past I've stripped down to a single RX and got utilization down to about 30%. You'll pr

G'day, I've updated code supporting the FT990 rig. It fixes a bug that caused set_mode() to interchange the RTTY and RTTYR modes. It fixes several bugs in get_channel(). in particular the reporting of transmitter parameters in split modes. Valid values for the channel parameter are channel nu
