I checked my notes and found that I did not record any free-running
tempco values. My observations were based on the scale factors I had
to use to get the temperature and DAC graphs in Lady Heather to
overlay each other. I initially
Hi
LH can get a bit confused about OCXO tempo. It's not really the software's
fault, as you point out - the data just isn't there.

Ummm…… e….. wasn't the ARC-164 the original HAVE QUICK radio? They
certainly came out in both HAVE QUICK I and HAVE QUICK II versions.
Yes, that was 30 years ago….

Several years ago I bought a very nice 24U EMC screend cabinet at auction. It

was a shipborne havequick timing reference. I still have the
I think what I'll do is collect some data on a batch of TBolts that I have
soaking here. It seems to me there's enough information that, over time, the
tempco can be accurately determined. I mean, when you see LH plots with glaring
diurnal patterns in both temp and DAC it's easy to roughly

It was certainly one of the very first radios with it - but there was also
a non HQ version (the most obvious sign was that the synthesizer slice just

The ARC-164 most certainly existed long before HAVE QUICK came along. My only
point was that HAVE QUICK didn't exist before the ARC-164 got it.

Hi
The OCXO is a dumb version. It does not talk to the TBolt. There's no way to
check it in software. There are a few examples out there that have late model
stickers on the outside and earlier parts on the inside. There's pretty much no
way to know what you have without opening up the box.

The real answer to that is going to be a that depends kind of thing. The
population of units in the basement are all within 20% of each other as

Hi Tom,
but they could have achieved the same exact result by using scientific
notation such as:
2.3E-010
or:
2.30E-010
or:
23E-011
to note the higher internal resolution in the later case.
I realize that one can easily parse these raw outputs, if one can write
python or C etc
