>From Flex Radio advertising statements:

"Full duplex operation also allows very high speed (<10 ms) T/R switching
for CW and TOR digital modes."

"This is most notable when operating full break QSK at 40 WPM where you can
actually hear between the characters".

How can these statements be correct if the lowest latency is 86MS as
measured by W2RF?   Along with the other statements made on this discussion?

Al,

Perfectly well put!

I remeasured the current PwrSDR RX latency, using the delay from
known beacon transmissions, with DSP 4096/256:

192khz  1024buf   86ms
 96khz   512buf  152ms
 48khz   256buf  247ms

73 Ed W2RF
