How to Build a Preamplifier Transmit Receive Sequencer Circuit Diagram? This is a simple circuit and this circuit is useful in amateur radio VHF and UHF work where a mast-mounted antenna Preamplifier is used for receiving. The kit controls T-R switching and change-over relay sequencing so that high RF levels are prevented from accidentally being applied to the preamplifier during switching intervals.
