[time-nuts] Austron Oscillator Products

[skipp isaham]

Hello to the Group,

I picked up three or four Austron Inc (Austin Texas) Crystal 
Oscillators, all appear to be Model 1170.  52.000000 MHz and 28 VDC 
operation. The two power feed-through (capacitor type bulkhead) 
connections are clean, bare and unsoldered, so I'm assuming these units 
were never used.

The trusty Fluke Multi-meter indicated one of the two connections (XE1) 
was near/same as chassis ground, so input power (+28Vdc to XE2) was 
applied. Metered initial current was about 154 mA and the unloaded J1 
output looks like a very clean sine of at least 6 to 8 Vp-p and nearly 
spot on 52.00xxx initial start up.

There are two SMA jacks (J1 & J2), both seem to have the same output 
wave form.  Date of MFG is 10/81 and the part number is 302549-88

Little info on the current status of Austron seems to turn up in my 
initial web searching. These type of search results often mean the 
company is gone and/or swallowed up ("merged") by another company.

Would anyone here on the group have a basic history or Austron and 
possibly some data on their crystal oscillator line. I did see other 
oscillator models offered on Ebay as well as other products.

Based on the current draw, visual appearance, date of MFG and it being a 
high precision oscillator, I'm assuming it's got an internal oven, 
although it didn't start to get warm after the initial 20 min power on 
time.

Thank you in advance for your replies, see some of you at Hamvention 2024.

cheers,

skipp
