Beppe, You are probably going too low on one of the buffer settings if you are hearing buzzing with that machine. Try using the following settings for the buffers: Audio-512, DSP-1024, DMA-512. Let me know if that works. The DMA settings are on the Delta Control Panel Hardware Settings Tab.

I have immediately noted the very low latency (near real time) of this professional card. (buffer set to 256) The bad results is med/high noise background (BUZZZZZZZZZZZ) in receive and trasmit mode also ! In RX the BUZZZ level is mixed in band noise without antenna connect, inaudible when the antenna is connected. In TX the noise it is very high and confused/mixed with the speech. Playing with EQ / COMP and Compander with no results. The audio (SSB) chain is the same used with the "older" Extigy, without any type of noise: - Mic SM-20 Icom - Preamplifier/noise gate/compressor from W2IHY The "machine" is P4 - 2,9 - 1GBram (with Realtek on board sound card used for digital) The Extigy is installed again also, but without audio connection (only the USB is connected). Any suggestions........? Thanks !
