There are at least three advantages for external operation.

Ordered a small heat gun today. Has 2 temperatures and I am sure the low is

You left out IBOC, especially IBOC on AM at night. The FCC brass has zero

It is not cynicism if it is the truth.
The previous head of the FCC was none other than the son
of Gen. Colin Powell: Michael K. Powell.
The same Powell who allowed Verizon (and other telco's)
to stop sharing their lines and as a result made the
price of DSL skyrocket.

Truly impressive level of cynicism...

The FCC is a lackey of the present administration, which has a desire to
show movement re broadband internet for all. The
broadcast/telecom/communications industry is bypassing real competition
by simply getting the government to do by fiat what competition would do
at less cost and more utility.

The only thing they are worth is a 6 inch linear accelerator.

Back in my pre-time nut days my 5345 was both counter and lab reference
standard the 10.mhz output went to a D/A so all my instruments were referenced
to the 10811 in the 5345

One option was an ECL gate oscillator with a crstal in a T05 sized can.
TTL output oscillators of that era had too much jitter to be useful even
for short time intervals.

I have seen 2 different variations of this oscillator.
There is one that was used in the 1210D standard
that has a BNC connector besides the 9-pin connector
and this unit has EFC input on the 9-pin connector.
The second does not have

Hi
Another way to filp that around is that the same ADC's begin to degrade if the
broadband phase noise isn't at least in the 150's. With an 18 db penalty for
multiplying, that puts you into the 170's for phase noise out of the TBolt.
Even if the TBolt OCXO is that good (doubtful) building a mu

Whilst the close in phase noise of the ADC used in the TSC5115 may be
comparable with that of a 74AC04 the phase noise floor of such ADCs is
degraded when clocked by a 74AC04:
