Telemetry parameters (eqns)

[OK1ALX]

Hi

I might still overlooking something, but iam having hard time to update the equation parameters for the telemetry for station OK1ALX-1.

This is the sentence iam trying to send:
EQNS.0.05,0,0,0.05,0,0,0,0.5,-25,0,1,0,0.03,0,0  as you can see it here: http://aprs.fi/?c=raw&call=OK1ALX-1
also tried the long version:
EQNS.0.050,0.000,0.000,0.050,0.000,0.000,0.000,0.500,-25.000,0.000,1.000,0.000,0.030,0.000,0.000  with no effect at all :(

What is the problem, is there something wrong? It is not first time iam doing this, but the server doesn't react properly to my attempts :)
This is station with same telemetry script: http://aprs.fi/telemetry/?call=OK1COM-1 the parameters are correct there. This is how it should be on mine as well.

Thanks for any tips!

You're most recent EQNS was:

EQNS.0.050,0,0,0.050,0,0,0,0.5,-25,0,1,0,0.030,0,0

This would be the following parameters per value by my eye-balls:

0.050,0,0
0.050,0,0
0,0.5,-25
0,1,0
0.030,0,0

Did you really mean to apply the factors to the square of the raw values?  The equations are a*v^2+b*v+c where each tuple gives a,b,c.

Even so, I don't see that at http://aprs.fi/telemetry/OK1ALX-1

My APRSIS32 instance shows:



Are those the values you think you should be getting from the following?

2012-05-12 12:45:06 UTC: OK1ALX-1>APRS,LOCAL,qAR,OK1LOL-1::OK1ALX-1 :EQNS.0.050,0,0,0.050,0,0,0,0.5,-25,0,1,0,0.030,0,0
2012-05-12 12:45:36 UTC: OK1ALX-1>APRS,WIDE2-1,qAR,OK1LOL-1:T#021,141,47,146,000,000,00000000

Hi Lynn,

your results are correct, but somehow aprs.fi doesn't apply that.

73!

There was a bug in the equations processor, it's cleanup functions were
slightly too effective, making 0.05 a 0. Should work now!

Good deal! Glad you found the explanation, and even better, the fix.
Sounds like my -0 SSID remover that was causing shorter callsigns to
match longer wildcards (W4XY was matching a W4XYZ* wildcard).

We don't say it enough, but aprs.fi is a completely AWESOME
implementation! Thank you Hessu!
