CWOP data

Post by meadowlark »

For some reason my CWOP latitude and longitude is not registering correctly during the CWOP upload. I was using the latest Beta copy.

The coordinates for my station are: longitude 39.01.57 N and latitude 95.42.54 W - with that data entered in the configuration of Cumulus it changes the last two digits during uploading - in other words CWOP is showing
longitude 39.01.95 N and latitude 95.42.89 W.

Here's the "raw data" copy -

CW2327>APRS,TCPXX*,qAX,CWOP-2:@081849z3001.94N/09543.89E_098/004g007t043r000P000h57b10250eCumulusWMR928

The CWOP format for co-ordinates isn't degrees, minutes and seconds, it's ddmm.hh, where hh=hundredths of a degree. So I think it's correct. Well, most of those are correct, I've no idea where the ones with the completely different co-ordinates came from - were you experimenting?

No experimentation Steve. The only thing I had listed incorrectly was I had the latitude and longitude turned around, but it still remains that when my data string is uploaded to CWOP, the location coordinates of my site are not what is entered in my Cumulus configuration.

so 57 seconds = .95, and 54 seconds = .90 (but it's coming out as .89)

What's the problem ?

I'm confused now as to what you think the problem is. Most of those lines are correct. On these lines:

CW2327>APRS,TCPXX*,qAX,CWOP-1:@081945z3901.95N/09542.89W_065/005g005t049r000P000h51b10240eCumulusWMR928

Cumulus is getting your co-ordinates correct, according to what you have said.

But on other lines, e.g.

CW2327>APRS,TCPXX*,qAX,CWOP-3:@081934z3901.95N/09417.10E_116/007g010t048r000P000h51b10240eCumulusWMR928

Your longitude has gone East and changed value, and I can't see any way that Cumulus could be doing that by itself.

Some times I am just a tad bit slow, but after taking a closer look at what I thought was a problem, the solution became very evident. CWOP perimeters for latitude and longitude have to be entered LORAN and then they're converted by CWOP and appear as they should. I was not using the LORAN data.
