Thanks Bill, Looks like you get the same results with your F-1500. The high cut-off I can set is also 3650Hz. Wonder if Dudley or Tim could comment on this if this is a limitation of the F-1500 or PowerSDR. I was getting into this when I was trying to setup a MaCRO for Win-Warbler which handles a 4khZ spectrum. It looks like the maximum bandwidth on TX is 3650Hz. Correct me if wrong please.

Message-ID:<4f39a391.6060...@comcast.net> Content-Type: text/plain; charset=ISO-8859-1; format=flowed John, I have found that the Flex CAT documentation is not all that accurate. Some commands don't work as documented or return unexpected results. According to the ZZTH command as documented in CAT_Command_Dictionary.pdf, sets or reads the TX Filter High setting within a range of 00500 to 20000; The documentation indicates you get get the current ZZTH setting by sending ZZTH; My Flex 1500 returned ZZTH03100; . This corresponds to the the "Transmit Filter High" value of 3150 found on my Setup, Transmit tab. If I try to enter 20000 as a "TX Filter HIgh" value on the setup, Transmit tab, it drops back to 3650. Sending ZZTH20000; to the Flex1500 gets no response. Sending ZZTH04000;, ZZTH03000; etc gets no response. It is either broken or mis-documented. The ZZTL; command for setting the "TX Filter Low" exhibits the same behavior, you can read it but you can't set it. These results are not all that surprising based on my experience with the PowerSDR CAT commands. It appears that the commands get documented, more or less, but it also appears that nobody ever tests the commands to see if they actually work.
