[time-nuts] Motorola GT+ and UT+ Receivers Available

2012-07-11 Thread John Ackermann N8UR
TAPR has obtained a small number of used but tested Motorola GT+ and UT+ receiver boards. The gang here is probably most interested in the UT+, which is an 8 channel receiver with 1PPS nominal accuracy of 50 nanoseconds. TAPR is selling the UT+ receivers for $25 plus shipping, and the GT+ for

[time-nuts] Proper setup of a Trimble Thunderbolt

2012-07-11 Thread Gary Fiber
I purchased a Trimble Thunderbolt. Is there a web page or does someone have a set of written steps to set up the Thunderbolt? There are quite a few adjustments available for it and it makes sense to me not to reinvent the wheel. I have googled and got some results using Tboltmon. Have tried

I would like to put my Thunderbolt into a chassis with power supply and would like to have the most favorable thermal environment since the unit is somewhat temperature dependent. I was thinking of mounting the unit in insulating material, but am worried it will get too hot to the point the

10MHz output you mean, not 19MHz, surely it was a typo. Yes, best to use LadyHeather: learn how to use and you will have the best monitoring utility for the TBolt. On Wed, Jul 11, 2012 at 5:18 PM, Gary Fiber gfi...@comcast.net wrote: I purchased a Trimble Thunderbolt. Is there a web page or

Yes it was a typo meant 10 MHz. I've got the readme for Lady Heather and will go through it. I was hopeful someone had any needed basic settings for the Thunderbolt otherwise I will leave it as it came out of the box from the seller. Gary Fiber K8IZ Sent from my iPad On Jul 11, 2012, at 10:36

I have mine in a nice case along with the switcher supply. Am debating on the need of including a small fan. I made a shelf from 2 sided PCB material and mounted the Thunderbolt onto that shelf. The switching power supply sits below the Thunderbolt mounted to the case bottom. Gary Fiber K8IZ

I tried putting my thunderbolt in a styrofoam box. It got hotter than I liked and didn't seem to perform any better than when I left it in a cardboard box. I worry about the long term implications for component life as the temperature goes up. Sent from my iPod On 2012-07-11, at 5:15 PM,
