Live Scanner Feed Updates

Our live Scanner feed is now being simulcast at Radio
Now you can listen at the alternate location just the same as you always have.
There are no plans to remove the current Radio Destiny feed, so feel free to use either method. The multi-format streams even support satellite internet!

With the new feed there’s added benefits, not only can you select
your player preference but there’s also an archives section that records the streams! So if you miss something there’s a way to go and hear what happened from several days ago, this is especially useful since a lot of the local news agencies are not covering what they used to.

Here's the link-

HEAR - Hospital Emergency Ambulance Radio

Our local heroes depend on a couple frequencies to get the message through when they are responding from the scene to the hospital. If you watched TV during the seventies you may have remembered the hit show "Emergency". Squad 51 this is Rampart; Minus the sideburns not much has changed in 30 years! Ambulances still report their patient's condition and ask for permission to administer meds via radio. The warbling noises heard were the ECG (Electrocardiogram) 12 lead transmissions, those classic sounds can still be heard on the Sullivan County Trunked system.

Some hospitals block all transmissions on their radios unless a specific DTMF tone is received. DTMF tones are the sounds you hear after pressing numerical buttons on a telephone in-call. Now since many of the agencies around here don’t radios with the telephone looking keypads they cannot "encode" into the hospital channel. The solution adopted by the Johnson City Medical Center is to have a designated dispatcher monitor a frequency, listen to traffic, then open the squelch on the hospitals radio by transmitting the appropriate DTMF tone sequence. "Johnson City MEDCOM" operates on 155.205, and is sometimes referred to as "MEDCOM 205". They conduct a weekly radio check on Monday mornings starting at 9:00 AM. If you're listening to 155.205 and hear a unit ask to be encoded, immediately switch to 155.340, you will be able to follow the conversation. However, sometimes the report may be relayed via the 155.205 frequency.

Johnson City Medcom benefits from two remote based receivers, these radios listen for traffic on 155.205 and 155.340 and retransmit anything heard on a UHF frequency. Listening to these can be useful if you live far away enough to not be able to hear the ambulances calling in their report.

The FCC previously set aside designated channels for medical use referred to as medcom. These frequency pairs are used nationwide but may sometimes be shared with secondary users such as business or public safety. Medlfight uses MED9 for flight following and patient condition reports back to their base at Wellmont’s hospital in Bristol, VA (BRMC). If you live too far away to hear the repeater you can listen to the repeater's input frequency, that way you can be sure you don’t miss any of the transmission.

Since a lot of hospitals monitor 155.340 for reports they sometimes use the CTCSS squelch (Tone) on their radio. Many of the hospitals rely on a remote base placed a strategic location like atop a mountain to facilitate the communications link in rugged terrain. Most hospitals simultaneously listen to an alternate channel; these would be used in disasters or in the even of equipment failure on the 155.340 frequency.

WEMT moving to Holston Mtn

The FCC recently authorized local television station WEMT to move its transmitter from Viking Mountain in Greene County, TN to Holston Mountain
in Carter County, TN. The station expects the move to be completed some time in 2010. In related news WCYB was granted a temporary authorization to increase their transmitting power 400%. I'm guessing they underestimated how many people in the fringe areas had snowy reception, reception with a signal strength too low to handle the digital transition. We'll keep you posted on any changes, look forward to segment on antennas and learn to make your own TV/Scanner antenna.

Scott County Earthquake

Scott County, Virginia had a Magnitude 2.9 earthquake on August 14th.
We'll all hope we never have a "Major" earthquake in this area, but should the
worst occur having the right frequency can be more than just recreational.

While too numerous to list here, any agency may be operate for a different cause.


  • School Bus frequencies - Evacuations, shelter ops
  • Water Companies / construction / highway depts. - Debris Removal / Rescue Ops
  • CTAF Aviation - Survey, Fire Support
  • State Police - Security, Perimeter Checks
  • Fire Departments - Food and Water Distribution / Fire Patrol
  • Highway Departments - Bridge Inspections
  • Amateur Radio - Message Relays, General Welfare Traffic for civilians, shelter ops
  • Power Companies - Rescue Operations collapsed buildings (bucket trucks)
  • Forestry / Game Fish - Rescue Ops, Security, Food and Water Distribution.

These are just sum rough examples, there are established emergency plans we'll elaborate on in
the future.
