Subject: One-Way In-Car Radios


The current practice at VRG/FFCS events for on-track incidents or disabled cars in harm’s way is to

use black flags at each corner station, indicating all drivers are to slow to 75-90% of race pace and return to pit lane so that emergency vehicles and on-track assistance can be dispatched.  In many instances, difficulty discerning the non-contrasting black flag from background clutter or drivers otherwise missing the black flag (as well as the Checkered Flag), cause additional loss of track time.  Drivers who have missed flags also must typically report to the Driver’s Committee, who often assess penalties.


A Radio Solution:

Many oval track racing organizations use in car radio receivers (Nitro Bee and Raceceiver) with earbuds to notify drivers of on-track emergency situations and other relevant information.   These receivers have limited range for road course use, and therefore a new style of receiver (Scan Ceiver X16) with an external antenna has been tested by FFCS at several tracks with successful results using a 5-watt handheld radio transmitter.  Use of these radios by FFCS participants will be voluntary at all events starting in 2023.


The radio of choice for the series is:

  • Scan Ceiver X16

  • Compact design (2” x 4”), with external 1” antenna built in

  • 3.7v battery with 24 hours life on full charge via USB

  • Volume control and automatic squelch

  • 16 channels with voice prompt and has a programmable scan function

  • Channel frequency range: 400.000 to 470.000, programmable with downloadable software.

  • Push to talk button is disabled


Use & Application method:

  • FFCS is licensed to use two channels.  Channel 1 is 451.8000, and Channel 2 is 456.8000.

  • We will use Channel 2 and when purchased you should request this frequency.

  • An FFCS official will monitor the track’s flagnet (race control) frequency.

  • The FFCS official will rebroadcast the following information from race control over the radio:

    • Green Flag

    • Double Yellow (Full Course Yellow)

    • Black Flag All

    • Black Flag (with car #)

    • Red Flag

    • Checkered Flag

  • This information is advisory only; actual on-track flag conditions take precedent.

  • While racers are on the false grid the FFCS official will conduct a radio test so that racers can confirm operation of the radio and confirm volume is set.

Known issues:


Drivers Affected:

  • Any drivers competing in the FFCS events may voluntarily use the radio receiver during all on track sessions.

  • Drivers with existing 2-way radios may tune/program their own radio receiver to the 456.8000 frequency used by FFCS.  Note: when using this frequency, push-to-talk transmissions will not be allowed, as they will interfere with FFCS communications to drivers.
