As noted in the earlier post my earlier I had a Z3801A in which the
receiver would err out after as little as 20 min. this was 6CH Motorola
Oncore which had I guess reached end of life after 20 years and 15,000
hours. A friend offered me a used 8CH Motorola VP-Oncore on the
condition I report out on what was involved in using the newer receiver
in my older Z3801A.
Here is what I have observed so far. The 8CH VP Oncore version is pin
and command compatible with the Z3801A ( and likely other 6CH Oncore
based GPSDO's) and the three (apparently) more popular programs ( HP
SatStat, Z38xx, and GPSCon).talk to the receiver so far without error I
have not tested all the commands but all of the standard stuff seems to
work. Basically this was a plug-n-play-n-survey upgrade.
The only question mark so far is the software does not report all 8CH
being tracked? Not sure yet if that is just a software limitation or if
there is a command I need to send the receiver to enable the other two
channels.
More positives . the VP receiver was billed as having a better front end
and seems to be living up to that ..SS reports are on average at least
20 points higher First time I ever saw all 6 channels with SS above 150
at the same time and occasional SS's above 200. The receiver PPS
comparisons to GPS are much less variable and erratic than the old 6CH
receiver was.
More of the used 8CH VP Oncore receivers may become available in the
next year. Not sure what the etiquette is here about posting things but
if there are no objections I will let everyone know. These are pulls
from older handheld units and apparently USA built complete with full
up serial number tags and version 10 firmware.
Insight on enabling and showing all 8 channels in the receiver status
window appreciated.
