Well, that's interesting. I have examples of both obvious pascals and the other units both on weather stations deployed by my own county's ARES/RACES group (reasonable: N3ESS-2, N3XRV-2, W3AHR-2, unexpected: AA3QN-2, N3NTP-2), and they _did_ mention something at a recent meeting about getting replacement weather sensors for some of the deployments. But, even so, _no_ station in my area is reporting in 10s of pascals, as specified by APRS 1.0.1.<br><br>Andrew Pavlin, KA2DDO<br><br><div><div id="SkyDrivePlaceholder"></div><hr id="stopSpelling">Date: Sun, 4 Nov 2012 21:31:53 -0500<br>From: ldeffenb@homeside.to<br>To: aprssig@tapr.org<br>Subject: Re: [aprssig] barometric pressure units<br><br>

Greetings, all.<br>
<br>
There seems to be a discrepancy between the APRS protocol
specifications and what stations are actually sending regarding
barometric pressure values. The APRS 1.0.1 specification says on
pages 64 and 67 that pressure should be reported in tenths of
hectopascals (or tens of pascals), but most stations (at least
in my area) seem to be transmitting pressure in pascals. But
there are other stations transmitting other units (what units
could a pressure of 8272 be?).<br>
<br>
Is this a bug, or a change in the specification that I haven't
found in the newer revisions of the protocol specification?<br>
