One commercial linear power supply that works well for the T-bolt is Power

This is a 16W triple output 5V 2A +12V (or 15) 0.4A -12V 0.4A unit. While 0.4
is under the warm up rating for the T-bolt it's OK for running. The fact that

Hi Steve,
as the manual 'asks' for an active antenna with at least 10dB external
gain, I would not expect the M12M to be too sensitive.. but as long as
you do have an active external antenna, it should not matter much.

I have to guess that if they were transmitting it in 1960, somebody else was

I suspect that if you dig into it, NASA (or whom ever) was doing range time

The short answer to the question of M12M GPS receiver sensitivity is:
Min acquisition signal level = -128 dBm (at module connector)
Min track signal level = -135 dBm (at module connector)
Max track signal level = -30 dBm (at module connector)
The background is that the sensitivity

The three ideas below assumes your software is getting the time from
the PC's clock and the WWV board is setting the PC's clock. If the
software gets the time direct from the receiver board, then it's
lilely time for new software. But assuming the more rational design

NASA used this code for time tagging the analog tape instrumentation

I was strongly criticized in the past but again look at HP's half width
cases like the HP 37203A, there are many instruments out there for next to
nothing in that size case and it looks very professional. My Dual Mixer goes
into one of those, and if you can not find one contact me
I believe they would both fit in a 1 RU rack cabinet.

James,
I used an old 1 u server case and it's accompanying power supply. The back
panel was already punched for a db9. All I had to do was drill some holes for
BNC output and sma for the antenna connector.
The big win was the 2x16 backlit LCD panel on the front which I hooked up to a

In the case of VHF, the link distance isn't all that far. Take your transmit
clock and put a one shot after it. Put a pot on the one shot and adjust it for
minimum noise on the RX signal. Very much like a fine tune knob. Low tech -
yup. Ham type solution - yes indeed.
