Last night I measured the voltages on the serial lines with a DMM. The TXD 
coming from the GPS was a solid -5.9 V. The RxD was 0 V.

Hi Greg,

I'm using a 12 V 7 Ah gel cell for the power and have a small Trimble magnetic 
puck antenna connected just for testing.

hi

i got and compiled the latest heather from Mark... v5.01.

you can tell her that it is a moto receiver.  there is a lot of discovery
commotion on the screen at startup.
i run it on a pi-3.

good luck

Re: [time-nuts] TAPR GPS Experimenters Kit

[Chris Waldrup]

Hi,

I have my board packaged up and am trying to get it working. 
Last night I built the cable to split out serial, 1 PPS and power. 
My unit powers up, and the 1 PPS and RxD LEDs are flashing and the green power 
LED is solid on. 
However I can't get serial to work and the TxD LED isn't flashing. 
I verified the pinout of the cable I made with a DMM. Pins 2 and 3 are swapped 
between connectors so the RX is going to TX for each of the two lines and pin 5 
ground is the same on both D sub 9 connectors. 
I have tried Lady Heather, Tboltmon, and even just pulling up hyperterminal and 
I'm getting nothing. 
My settings are COM1 9600 8-N-1 and I'm using a Dell laptop that has an actual 
serial port and am running XP.
When I'm Thunderbolt Monitor program, the green TX LED icon on the screen 
flashes and when it does the RxD lights on the M12+.
Just no TxD coming out of the M12+.
Has anyone else had a problem with this? If so is it fixable?
Thank you. 

Chris

Re: [time-nuts] TAPR GPS Experimenters Kit

[Gregory Beat]

I am looking for a spare Alubos ABP 800 series enclosure (115mm length),
mounting flanges are not required.
Some time-nuts readers noted in April, they had "extra" Alubos 800 enclosures 
(Bopla).

The TAPR GPS Experimenters kit (Synergy SynPaQ/E) used a custom Alubos case --
115mm in length with mounting flanges.

Contact me "Off List" regarding availability.

The Alubos # ABP 800 series "off-shelf" lengths are 100mm and 150mm.

RG-58 is very lossy at GPS signal frequencies.

The sweet spot on the cost/performance chart is RG-6.  It's widely available 
as low loss cable TV.  It's slightly larger diameter than RG-59.  It's 75 
ohms, but the loss due to mismatch is small relative to the cable loss.

[time-nuts] TAPR GPS Experimenters Kit

[Donald E. Pauly]

We are finishing a pair of HP5061B cesium standards which we have up
and running.  We would like to acquire a GPS disciplined oscillator
with 5 or 10 mc output for comparison with the cesium clocks.  1 pulse
per second would be nice but is not mandatory.  A roof antenna with
preamp that could drive 100 feet or so of foam RG-58 is required.
Does anyone have such a device that needs a new home?  If not, what
should we look for on eBay?

hi

I have been having great results with my M12 and Lady H.  I (foolish me)
had tried to cobble up a Perl program at first...  just browse through some
of the 400+ pages of heathgps.cpp to see why that was a bad idea!  Both my
M12 and my Tbolt are controlled by Heather running on two PI3s.

Now, i would like to get a Lucent RFTG-u REV-0 to run using the PPS from
the M12.  there is a nice PPS interrupt driven arduino sketch on the Sync
Channel Blog.  I'd love to hear from anyone who is also trying this.

Re: [time-nuts] TAPR GPS Experimenters Kit

Jerry -

I rarely use "raw" Oncore M12 commands these days, using one of the 3 common PC 
programs: Lady Heather, TAC32/SynTAC, M12Oncore(old Moto pgm).

How are you routing that 1 PPS signal?  Does your front LED pulse?
I wire 1 PPS to the DCD pin (DE-9M, standard RS-232), TAC32 can be configured 
for "which pin" (DE-9M) to sense that PPS signal.  
This is why I prefer to use Mark Sims' Lady Heather or Rick Hambly's TAC32.  
TAC32 program has a quick setting for config. receiver as Timing or Navigation.

IF you continue to have issues, perform the Hardware Reset (Lady Heather).
That will return your receiver to default factory with cleared settings.

Greg, Funny.  
Some of the Lucent boxes have been in strange places as well.  
Can you please check your PPS to see if you get a signal when in that other

Re: [time-nuts] TAPR GPS Experimenters Kit

[Gregory Beat]

Received a note from John Koster, W9DDD that TAPR had one complete GPS kit left.
https://www.tapr.org/gps_exp-kit.html

Received #CAB083 (2.1mm DC Barrel Jack to Bare Wire/"Pigtail") this morning via 
AirMail.  
https://www.moddiy.com/products/2.1mm-DC-Barrel-Jack-to-Bare-Wire-%28Open-End%29.html
Took about 10 minutes to finish building 2 adapter cables for the two kits.
I will have to post photos.

I used an old Linksys router power adapter (12VDC, 1A) for power and an old 
Motorola ANT62301 "HockeyPuck" antenna (Marine screw-base) on the patio (some 
obstructions).
http://www.dvq.com/stan/041127/TN-491B-motorola-gps-antenna.pdf

I could not get TAPR/CNS Systems TAC32 software to work under latest update of 
Windows 10 (I'll have to ask Rick, W2GPS about that).

Lady Heather, version 5 came to the rescue (Thank you Mark Sims).
Lady Heather recognized the Motorola M12 receiver quickly.

I performed a Hardware Reset and then started the Standard Survey.  
After about 10 minutes it was tracking, and continuing survey.

I did read the old coordinates and date from one M12 receiver  
it last operated in 2014 and its coordinates placed it in middle of Indian 
River, west of Melbourne, FL (Space Coast).
Many laughs about why the last report was in river:
1.) dropped off a barge or boat
2.) partially recovered from a Falcon 9 booster
3.) throwing contest from shore
