DSW-150 is a automatic T/R switch senses transmitted RF (as SwitchBox) and switches your antenna from receive to transmit using a relay. It shorts your receiver antenna input to ground to protect your receiver. Instead of using RF sense to switch the antenna, a control line input lets your key/keyer or PTT line switch the antenna. Works on all modes — CW, AM, SSB, FM, and digital modes.
