I considered that. Unfortunately the Heol Designs units don’t emulate the
SV6-CM3 and the Ace receivers were not a direct replacement. So it seems they
have nothing to offer at this time.

Heol Designs offers replacement boards for Trimble GPS receivers.

Heol Design's GPS receivers are based on the Copernicus II high performance GPS

The TSIP protocol is the same one we all know and love. But some of the values

sends them. I suspect that, alone, would make dropping in a

Due to the stickers, I don’t see anything with MX on it, but I presume you mean

the -x1 kind of implies that it’s TSIP, and from sniffing the GPS traffic in a
prior exercise, I can confirm that it is.

On the chip with the "MX" marking on it, what f/w version does it show
(usually v5.02 or v5.10)? I have a couple of CM3's configured for TAIP output,
but I have the programs for switching them to TSIP or NMEA.

I recently added code to Lady Heather to support up to 10 external com links
(serial or TCPI/IP). One is the receiver port, one will be a TICC, and two
are "echo" ports. One echo port echoes all the raw data sent by the receiver
and the other does the same thing except the data is formatted
I did see that one, but I am hoping I can procure something that isn't
from an overseas surplus scrapper. If I can't find anything else, then I
guess it's my only choice. Unfortunately, the Heol folks don't have
anything to offer here either. It's not a WNRO problem, as the week and

If your friends don’t have a CM3 spare, there is one on eBay item 141712522709.
It might be worth pulling the GPS part and testing it stand alone as there have
been numerous week number roll over problems surfacing. If that is the case for
yours then a replacement gets you nowhere.

I’ve had an intermittent problem with my ET6000/9390-6000 GPSDO where the
reported error (the FRQ: display on the LCD) initially is OK (low E-12’s) and
then creeps up to the limit (~500), and the tracking and locked LEDs go out.
I’ve spent some time troubleshooting this and it seems confirmed th
