−	The Portsdown team have developed an RF output switch capable of switching the low level output of the Portsdown filter modulator board to separate amplifiers for the 70, 144, 437 and 1255 MHz bands. Note due to high insertion loss, it is not recommended to use the switch above 23cms.	+	The Portsdown team have developed an RF output switch capable of switching the low level output of the Portsdown filter modulator board to separate amplifiers for the 70, 144, 437 and 1255 MHz bands.
