[time-nuts] T-Bolt oven / LH question

[Bob Camp]

Hi

If you leave the unit off power for a couple minutes, does the +12 current
start at something higher than 150 ma? It should be well above 500 ma at
turn on. If not, then the oven in the OCXO isn't doing it's thing.

Subject: [time-nuts] T-Bolt oven / LH question

Hello all,

I recently purchased a ThunderBolt on eBay. I believe the T-Bolt's
oscillator oven is not operating correctly. But, having never used a T-Bolt
or Lady Heather software I'm not sure.

Why I believe there is a problem:

1.    The T-Bolt's external case is barely warm (my guess about 100F)

2.    The positive 12 volt power supply current remains steady at about
155mA

3.    The temperatures displayed on LH software.
             Near the top left of the screen in white 22.29C
            Underneath in red -16.3C
             At bottom of screen above graph 16.2C


Question, is this normal? Do I need to enable the oven or change a
temperature setting?
Thanks in advance.
