Linear Amplifier Relay Switching at Jennifer Iva blog

Linear Amplifier Relay Switching. Required rf and relay sequence. After a few milliseconds delay, say at time t1, an “amp relay” line on the transceiver’s rear panel closes, in effect notifying the amplifier to prepare. Key closure, ptt line, or voice start (vox) at radio. The switching can be done by relays or some kind of electronic rf switches. Solid state linear amplifier external keying relay. I am building the t/r switching circuit for an hf linear amplifier covering 80m band to 20m band. This keying relay allows older linear amplifiers to be used with newer transceivers by providing a. The text below covers electronic circuit to sequence and speed separate relays (like dual vacuum relays) and describes how to sequence mechanically ganged contacts like those in open frame. The crydom ssr now drives a pair of potter & brumfield rtb14012f relays, one for antenna switching and one for amp keying. Their contacts are rated at 12 amps at 240 volts. This page deals with the entire system, including radio rf output. These can damage some transceivers. Many linear amplifiers have the feature to detect the carrier. Older linear amplifiers often deployed t/r relays which ran on higher dc voltage or even on ac voltage.
