Recently, I set up FLDIGI
to work with the FLEX 5000A. I have made a few contacts including one with QRQcw member, Nathan KO6U. The reports have been good and I do like how it keys the Flex, however I have a "latency" problem which must be fixed before any full QSK QSOs can be made. If any one contacts some one using the FLEX 1k or 5k with FLDIGI, please pass along their call as I would like talk about their CW (A2) configuration. Currently, I am using UA9OV's "CWTYPE" and it exhibits very low latency with either Flex model. Flex has their own cw keyboard called CWX as part of their main software package but when the turn around response is reduced for QRQ, the element and space timing is no longer is acceptable (in my opinion). This will be fixed but in the meantime, CWTYPE is my choice for the now.
Here is the configuration I used with the FLEX:
Added another sound card (simple USB sound adapter - 8 bucks) and it's LINE OUT feeds LINE IN of the FLEX A to D. This avoids using virtual audio cables (VAC) and their inherent latency. The FLEX mode is set to SSB/USB and then the mixer for the USB adapter and FLEX are used to set drive levels (which works fine) for 100 w out. The latency appears to be caused by FLDIGI (using Windows version) rather than the FLEX because this same LINE IN has been used for other modes and I have not found it to cause delays of the magnitude I have now. I hope this is not true and FLDIGI is as responsive as CWTYPE.
