SteppIR tx inhibit

This simple circuit, adapted from the N8LP version, cuts the TX enable line in the tx/rx whilst the SteppIR is tuning. When running a linear amplifier it is an essential requirment to avoid the “whilst retuning” transmit power being exceeded.

Read your transceiver manual to understand how to use the output from the relay to inhibit transmit
