Changelog

A new eLMS function now obtains service contour data from the FCC Contours API based on GLOBE30 terrain data and stores in an eLMS table.

Contour maps for FM engineering applications filed after September 25, 2019 and filed in LMS now use eLMS contour data whenever possible.  This will hopefully resolve some of the issues that we have been having with the previous method of calculating field strength curve distances (which was done locally) causing some strange artifacts on contour maps (such as the "wings" effect on deep nulls in directional antennas).

As HAAT and ERP is not manually entered on LPFM (Schedule 318) forms like they are with other broadcast services, many times the information carried on an FCC form is incorrect as it may reflect the previous location.  

This enhancement adds functionality that on all LPFM (FL) applications with type codes MOD, MODA, CP and CPA, eLMS will call the FCC Contours HAAT API to obtain correct HAAT and then use that HAAT to calculate new ERP. 

New schema field table reclms_fmeng haat_elms_calc will indicate "Y" if this method was used.

eLMS is a product of REC Networks in an effort to improve on the raw data product currently offered by the Federal Communications Commission for broadcast applications filed in the FCC’s License Management System (LMS).  eLMS parses the information directly from the filed applications and then places it into a database that can be used throughout the REC system universe.

eLMS Enhancements – First weekend project.

REC is working on a major project to address the shortcomings of the raw data that is provided by the FCC since FM radio converted to the LMS system on September 25, 2019.  

Rebuilt system to obtain listener counts.  Information on Twitter playlists now display correct counts.

Built new interface to Disogs to get cover art for Delmarva FM (REC-FM).  The system will cache cover art.  Any cover art that we do not have, the system will attempt to retrieve the cover art from DIscogs.

We will eventually build a similar ability for J1.

This cover art only covers what is viewed on the recnet.com home page and on the J1/Delmarva FM popup "J-Player".  The mobile app, TuneIn and Roku get their cover art from their own system sources.  

If no cover art is available, the Delmarva-FM logo will be displayed. 

A new widget appears on the left sidebar of the recnet.com website which displays any non-operational conditions that are currently reported on the REC Operational Status Page (recnet.com/motd). 

New functionality has been added for when scheduled database updates take place, the Operational Status Page and Status Widget will get automatically updated with an orange "Updating" status.  The Status Page will give details of which databases are being updated.

REC placed a couple of emergency fixes into various systems this morning to deal with the ongoing bad information coming from the FCC on LPFM records.

Modified back office systems and FCCdata to regard a station in which the app_antenna.aant_antenna_type_code from LMS is blank.  Normally, this is the field in LMS that designates an antenna to be directional or nondirectional.  Systems will treat blank entries as nondirectional facilities.

Did a complete rebuild of the system used to obtain travel reports for JR East Japan Railway.  

We have returned JR EAST to on-air, website, Twitter and the mobile app.

There may be some additional table building necessary to determine any new English language nomenclature used by the railway.

Installed some modifications and added monitoring to support the site changes at JR East in order to obtain train delay information for the Kanto region.  Modifying the code on an ongoing basis to handle the new delay status messages from JR East.  Any JR East delays that the system is able to decode will be displayed.  All issues will be logged.  

Until the new JR East interface is stable, we have curtailed all tweets from the JR East interface to the @j1_travel Twitter account.

We will be working on numerous bugs reported on myLPFM 2.0.  This includes reports of missing contour maps, nonfunctional census information and false positives in results.

ETU: Sunday 9PM ET.

Determined and cleared the issue that was causing the false positive result.  The Channel Search was not properly handling some LMS applications.  

Determined and cleared the issue that was causing the lack of contour maps.
