OT: FS: Trimble Thunderbolt GPS Disciplined Oscillator

[Jim Sheldon]

For sale - Trimble Thunderbolt GPS disciplined oscillator with a 3 voltage power supply and the proper cable to run it.  All that would be needed to connect it to a K3 with the external reference board in it would be a SMA male to male cable and a powered GPS antenna capable of running on 5 volts.  Thunderbolt is Rev A, dated 4/11/03 and it has the 10 MHz splitter mounted so there are actually two 10 MHz connections available.  The GPS antenna connector is a type F female (cable TV connector) and the 5 volts for the GPS antenna is supplied through this connector.  Voltages necessary are +5 and +/- 12 DC.  Don't remember the current requirements off hand, but the power supply that will come with it has more than sufficient capacity to handle it.  It's a switcher but shielded and very quiet - I never did find any birdies from it even when it was connected to my K3's EXREF board.

The only reason I'm selling this is I've been given a Rubidium 10 MHz standard that will be a bit more portable and sufficiently accurate for my needs.

Asking $90 shipped anywhere in the US only (on the no-export list).  Included will be the Trimble "user manual" and some open source freeware control software called the Lady Heather control program that will monitor everything and actually set some of the parameters via the DB9 RS232 connector on the Thunderbolt.

Interested?  Reply off list - pix available on request - off list.  First "I'll Take It" off list will get it.

Cash, money order or PayPal accepted -

it is working fine.....

just spent the weekend at a shopping mall ham radio demonstration ... w3c....

I get the amp home and i head a bit of a rattle...
open the lid and a zinc screw drops out .... no washer yet ....

To disassemble or not ,....
  that is the question....

if the screw is part of a heatsink.... i better open it up ////
if it's part of a mechanical fixture maybe ....

what would you do ,.,,

i'm pretty certain what I'm going to do .
