146 MHz RB-TV: Difference between revisions

Revision as of 11:21, 16 February 2017

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:

http://rsgb.org/main/operating/licensing-novs-visitors/online-nov-application/146mhz-147mhz-nov/

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

Sam Jewell G4DDK, 8W amplifier kits, pcb, manual etc. http://www.g4ddk.com/144MHz8WPA.pdf
