[TenTec] Future of Radio (Was) ARRL product review test change

[George, W5YR]

While "some" radios do use 12-15 KHz for IF-DSP, others now use 36-40 KHz
and do a much better job, in addition to using 32-bit processing and 24-bit
ad/da conversions.

But you are correct: when DSP processing is effective at "conventional"
IF's of around 455 KHz and above, we should expect to see much better
performance in many areas.

Faster, but affordable, processors appear to be the key . . .
