Lots of cheaper HF stuff like the G106 can be controlled, and there seems to be one or two CAT VHF/UHF radios you can find used for less.
Any Baofeng can be connected to a raspberry Pi with a soundcard and a few passives, it can't be tuned but it can send and receive audio on a manually configured channel, and you can use multiple at once if there's only a few channels of interest in your area.
A HackRF and some filtering and an amplifier will work, it might not be the best quality audio, but we've got AI enhancement now so that's not the worst thing.
Might be able to get this thing: https://www.lilygo.cc/products/t-twr-plus to do what you want without too much trouble.
And of course, for RX only there's RTLSDR.
