Re: [time-nuts] Low Drop Out Voltage Regulator

Linear Technology LT1170 It's an integrated switcher, you need an inductor and a schottky diode (and a couple of capacitors and resistors) but it will run with a small heat sink and will help extend battery life. It's available in several packages, I prefer the modified TO-220 (5 pins) The

John, The unit shipped with Austron's 1150 OCXO - a VERY nice oscillator. I also believe that they sold a bunch of these units to the US Navy for portable references to sync up Subs. Rob -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Ackermann

Re: [time-nuts] Low Drop Out Voltage Regulator

Hi Brian, One fairly elegant solution is to use a DC-DC converter module. The 50 watts you need is a bit high but possible. The Vicor VI-200 (100W) and VI-J00 (50W) http://www.vicorpower.com/products/dc-dc/converters/ would suit. They are expensive but do turn up on eBay. Typical input range is

Re: [time-nuts] Austron 1210D Manual Update

Interesting historical note - if you look at P37 of your scans, it shows a Sulzer 1150 OCXO. Austron acquired the OCXO product line from Sulzer, and continued to manufacture in house for several years. Austron then sold to Datum, Datum to Symmetricom. Chuck Norton I believe purchased the

Hi John, Not heard that one before. It is always possible that there was some batch selection, but unaware of this during my time (July '85 to Dec '88). Rob -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Ackermann N8UR Sent: 09 March 2007 13:29

[time-nuts] Need some help with Motorola Oncore VP Back in Binary mode

Hello I need a little help I bought a Oncore VP board with 8 channels for my Z3801 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItemitem=250082966589sspagena me=ADME:L:RTQ:US:1 Motorola P/N: B8221Z1116 This has a battery in it. It was tested by the seller by placing in the NMEA

Re: [time-nuts] Need some help with Motorola Oncore VP BackinBinarymode

This is a receive only interface, (Bill K8CU web pages) to monitor the Oncore receiver (something I designed a while back to play around with). The program that Randy informed you of, TAC32, will communicate with the receiver and you will be able to change the unit to a 6 channel operation,

Re: [time-nuts] Austron 1210D Manual Update

PMEL is the correct term in the Air Force. It stands for Precision Meteorological Electronic Lab, it the branch of the Air Force that does test equipment calibration. The 1210D was standard test equipment for labs that did not have rubidiums and cesiums, which was quite a few. When I worked

Re: [time-nuts] Austron 1210D Manual Update

Close, but not quite. PMEL is an acronym for Precision Measurement Equipment Laboratory. They are metrology labs tasked with maintenance and operation of the standards for electrical (voltage, current, resistance, frequency, and time) as well as mechanical standards for weight, pressure, etc.
