A new sample of bright flat radio spectrum sources selected at 8.4 GHz and consisting of objects brighter than V= 17 is discussed. The sample was selected with three purposes in mind: (i) to find low-luminosity BL Lacertae (BL Lac) objects with radio luminosities comparable to those of BL Lacs selected at X-ray frequencies; (ii) to investigate the differences between BL Lacs and other flat radio s...
