Post subject: | Lake Mead NRA / Hoover Dam |
On a recent visit to Hoover Dam and Lake Mead, near Las Vegas, I discovered a VHF trunking control channel. It appears to be a two-site VHF P-25 trunked system, possibly to cover both the Hoover Dam area and likely the Lake Mead National Recreation Area. I had received reports of hearing the control channel from site 2112 on 172.1375 MHz, and I found the control channel for site 2122 on 172.1375 MHz loud and clear at the Hoover Dam via a close call hit on my Uniden 436 scanner. I was unable to pick up the control channel from site 2112 on my visit. It only shows two sites on the air right now, and no users were seen affiliating or using the system while I was monitoring. Both the Hoover Dam police and Lake Mead NRA operations were on their normal VHF conventional channels. Here is what I found via PRO96COM: System ID : A52 WACN : BD000 Tower Number (Decimal): 2-122 Tower Number (Hex) : T027A Flavor : Phase 1 -Tables #Format: Table ID,Base Freq,Spacing,Input Offset,Assumed/Confirmed,BandWidth,Slots 00,171.00000,0.01250,-7.47500,"Confirmed",0.01250,1 01,171.00000,0.01250,-7.30000,"Confirmed",0.01250,1 02,171.00000,0.01250,-7.16250,"Confirmed",0.01250,1 -Frequencies #Format: Channel,Usage,Frequency(/Slot),Input Channel,Input Frequency(/Slot),Input Explicit(1/0),Hit Count "02-0089","c",172.11250,"02-0089",164.95000,0,0 -Neighbors #Format: TowerID,TowerIDHex,System ID,Channel,Frequency,Tower Name 2112,"T0270",a52,"01-0091",172.13750,"" |
