WA8LMF  UI-View  Webserver

WARNING 1:  This page links to a server hosted on a PC connected to a low-bandwidth (300K/sec) consumer cable modem account. Due to limited bandwidth of this connection, images may occasionally fail to load. If one or more of the maps fail to appear, hit "Refresh" or "Reload" on your browser toolbar. 

WARNING 2:  Disable automatic image resizing in Internet Explorer 6.x or Firefox. The maps sent by this server are likely to be much larger than your browser window. The automatic downsizing for large images provided in these browsers will make the thin lines and small details on the maps an illegible blur if not turned off. With resizing turned off, you will have to scroll down and/or to the right to see all of the maps.

Background on the WA8LMF Webserver Setup

The webserver produces a multiple map display.

• On Map 1 "Western US 30M HF", I am combining off-air 30-meter HF position reports (mine and everybody else's) as heard in Pasadena, along with posits for myself only from the Internet system. 
   
• On Map 2 "L.A. Metro Area", I am combining off-air southern California posits (mine and everyone elses) received off-the-air on 144.39 Mhz 2M VHF, with posits for myself and others from the Internet system. If i am out of town, this map will continue to show the greater Los Angeles area without me.
   
• On Map 3 "Follow Me", I display ONLY Internet posits for myself, and anyone else within about 25 miles of my current position received via the APRS Internet system, combined with 2M monitored off-air in the L.A. area and 30M HF monitored off-the-air. This map scrolls to track me as I move. If I am out of town, this map follows me. It may also show the local APRS activity in the area I am in (if the local activity is reaching the APRS Internet system). 

This display, served by the UI-Webserver component of UI-View,  is created by three copies of UI-View32 running simultaneously on the same computer. All three instances are connected to APRS Internet servers using filter ports set to receive JUST my own callsign and nearby stations.  

A Kantronics KAM dual-port TNC listening off-the-air to 30M HF 10.149.3 MHz (with a Kenwood TS-50) AND two meters 144.39 (with a Kenwood TM-221) is connected to the AGW Packet Engine Ver 2004.1108 . AGWpe separates the HF and VHF streams received from the TNC via a single serial port. Instance 1 of UI-View has the AGW port mask set to accept only the HF stream. Instances 2 and 3 of UIView have the AGW port mask set to accept only the 2 Meter stream. 

     NOTE:  This is a lousy HF receive location with a horrendous noise level from a leaking cable TV trunk (not my provider!). A dipole made from two 30-meter Hamstick mobile whips mounted back-to-back about 20 feet (6 meters) above the ground is used for HF receive. The dipole's broadsides face south-west and north-east (toward the majority of the rest of the continental US).

All three instances of UIview are set to capture a map automatically every 2 minutes.  Only the first instance is running the UI-View webserver. I have modified the original UI-View "special pages/index.html" code to insert all three map images into the webpages served by the first instance.

• Instance 1, a.k.a "Western US 30M HF", shows a static map captured from Precision Mapping 6.0 zoomed to show about 2/3rds of the U.S. (Range scale is 900 Miles.) 
   
• Instance 2 , ak.a. "Los Angeles Metro Area 144.39 MHz", shows a static map captured from Precision Mapping 6.0 zoomed to show the greater Los Angeles area in southern California. (Range scale is 32 miles.)
   
• Instance 3, a.k.a "Follow Me", is a scrollable dynamic map generated by the PA7RHM mapserver plug-in for UI-View. This utility captures maps from the Microsoft Expedia webserver, and makes them usable with UIview. The display is zoomed to  a 10-mile range scale and is set to follow my mobile (WA8LMF with no SSID) as as I travel throughout North America. The display on this map is a combination of activity monitored off-the-air from 144.390 MHz in Pasadena, CA, and an Internet feed filtered to show me, and any other station within about 20 miles of my current position.  (This display uses the JavAPRS filter command "filter f/WA8LMF/30 -p/CW" .) As I move about the country, out of range of the off-air receiver, the Internet feed will continue to provide a current position display. 

All of this is running under Windows 2000 running on a Via 1GMHz micro-ITX motherboard with 512MB of RAM connected to a Linksys WCG-200 "Wireless Cable Gateway" combination cable modem/router/4-port switch/WiFi AP. Details on the "Ham Super Server" setup that runs this site are here.
