Has anyone coupled a wireless adapter to a TBolt so that it can be accessed
from a computer in another room. This would be convenient for me if it
could be made to work.

Pretty much any Bluetooth serial adapter should do it. Running a cable
would be cheaper though.

Anyone else lose an 18x?
I assume you have tried power cycling them.
I lost one a while ago. Similar. It just stopped doing anything useful.

Here is my two cents worth
20 mv output, sure sounds like something is broken.
It should be fixed before it is modified.
The 2.49 volts on the Red input voltage seem LOW, More Vcc maybe.
The Grn labeled wire, FreqCtrl input should be about 1/2 VCC for testing.
If you do 'need' to modify the

I agree with Warren. The VCC seems way too low. Interestingly, noone else
seems to think so,
or did not notice it.

Not so, if the resistor values are correct this is the voltage that one
should get.

It was noticed, but it is consistent with the resistor values used in
the circuit.
The crystal current is determined by the dc emitter

You can always try to see how it performs with a cheap crystal, padding
out the ESR with a resistor to determine the ESR limit at which the
circuit fails to oscillate.
The crystal current doesn't depend strongly on the crystal operating
Q(as long as the circuit oscillates), so using a cheap
You can estimate the crystal current by measuring the RF voltage across
the 15pF cap in the oscillator circuit and estimate/measure the varactor
and trimmer capacitors.
Alternatively, temporarily replace all these caps with a 33pF cap
connected from the inductor in series with crystal and ground.
A couple more thoughts;
Is the VCC (Red wire) current draw correct?.
Should be 1.3 ma (per the schematic values) with the 470 Ohm and
more like 7 plus ma with the 47 ohm.
AND I don't remember seeing, IS the Freq real close AND can it be tuned by the
cap and Green wire voltage?

Attached plot of jump in my Z3805. Looks like there was a jump and
then then a rapid track back to the normal frequency drift. Comments

A man with one clock knows what time it is;
A man with two clocks is never quite sure.

Thus one cannot arbitrarily increase Vcc without considering the consequences
...
True, but with the AC voltages as low as they are, I do think it is safe to
think that the crystal current should be higher.
I was not suggesting to arbitrarily rise the Vcc, I was asking any chance it is
at
Warren
I agree, it's certainly possible that the external circuitry should have
a higher operating voltage than 5V.
A crystal current of 50uA to 1mA or so might perhaps be expected for a
typical 10MHz overtone crystal.
Unless some non standard crystal cut with exceptionally high ESR is used.
I just saw your schematic of the rest of the buffer circuit. Sorry I missed it
early.
The Osc Vcc is shown driven from a 510 Ohm resistor, and with the total current
thru the 510 res at under 2 ma,
Looks like Osc Vcc should be at more like 4.0 volts instead of 2.49 volts.
