how wide a bandwidth can I send via DAX?

Simon Lewis

loving my Flex 6500 btw

very impressed by it - i really love the pandapters

quick question ... how wide a bandwidth can I send down DAX??

Can't see to find how wide FLdigi will decode for example or cw skimmer in pileups

any ideas?

apologies if its a common question .. I did a search and could not see an answer

thanks

Fldigi will decode up to a 4Khz bandwidth. Multipsk in "direct IQ mode" will detect RSID's over a 192 Khz range. .  CW Skimmer with Smart SDR will decode pretty much the entire CW portion of each band via the SDR Bridge .

DAX provides about 10kHz of real bandwidth in a 24ksps payload that gets upsampled to 48ksps in you are using Windows sound cards.  There is a raw_iq command that can be sent if you are using the SmartSDR TCP API which will expand this to 20kHz of bandwidth as IQ data.  DAX data is centered on the slice receiver that the DAX channel is associated with.

DAXIQ provides 24, 48, 96 or 192 ksps IQ data with approximate bandwidths of 80-90% of the sampling rate.  DAXIQ data is centered on the panadapter that the DAXIQ channel is associated with.
