146 MHz RB-TV
UK radio amateurs with full licenses have been given access to an extension of the 2mts band between 146 and 147 MHz but only for experimental modes. This is done on a temporary basis and you will need to do an on-line application for a NoV to your current license using this link:

The RSGB band plan now includes (and encouraged) the use of Reduced Bandwith Digital ATV (RB-TV) using 500 KHz centered on 146.5 MHz.
RB-TV is not possible using "normal" DATV equipment and requires the use of equipment developed specially for the mode.
Other equipment needed includes:
- Filters
- Power amplifiers
