Also remember that when a relay is rated for say 24V it will work within a range between 17V and 36V (specs may differ). So when you've a +/-18v PSU you may be able to power both audio and relays from it. Unless you're building a complicated device like a mixer or so, I think a separate PSU for relays is overkill.

Telecomms. spec. relays should be used. I used "Type 47" relays in a preamp, with good results. I have also used reed relays. Polarised relays still need a diode; they are polarised with a magnet to reduce the switching current in the coil, increasing sensitivity.

Modern small relays rated for audio have the right kind of "rare metal" contacts that are self cleaning to a degree. However reed relays designed for audio excel at this task. They also switch quickly with little bounce. Off topic: test fixtures often use mercury wetted reed relays to produce pulses with sub nanosecond rise time and no bounce.

Both the receive audio and the transmit audio will be routed to a recording device. Normally, audio will be routed from the external speaker output to the recording device. However, when the Push to Talk is activated, audio from the microphone will be routed to the recorder instead of the audio from the speaker.
