[TenTec] TenTec Digest, Vol 156, Issue 4

Yes, it used to be much worse.
It is now 350 mS unless there has been some VERY recent change.

Barry, if you say it's better, please specify who measured it and
approximately when.  
Otherwise I strongly disagree.

I am quoting recent measurements by Rob Sherwood.
Somewhere buried in 10,000 emails I have a recent email from Rob confirming
this.
It was while running one of the big contests earlier this year.

I'm not talking about old 5000 rigs, I mean the new flagship line, 6xxx.

Rick, the latency on the latest SDR offerings has come WAY down, especially
on the Flex 6000 series.  They ARE contest capable.

I agree on the knobs.  I applaud the Flex Maestro interface panel - I think
it's a harbinger of products to come in the future, where many vendors can
offer various front panels that can be interfaced to many different SDR
types.  Or someone could write the code to use an Orion front panel to
control an SDR, etc.

For me, the draw of the direct sampling SDR radios (ANAN, Flex 6K) is that
their receivers simply sound better than the best superhet/dsp i.f. radios.

With the introduction of the not-overly-impressive IC-7300, perhaps we'll be
seeing several direct sampling (DDC/DUC) bundled in a fully knobbed
self-contained box in the next 1-3 years.
