It won't happen in a consumer-grade radio due to legalities, so there won't even be provision to enter keys even IF you could get them. Even software-based reception is a near absolute write-off. You'd have to intercept the 128 or 256 bit encrypted key & decrypt it before the next key update. When NS moves to the new system, it is likely that keys can be delivered over the air...and can be done at a time interval of their choosing....which will be certainly done at a time interval vastly shorter than the large time it would likely take to decrypt a key.
There will still be lots to hear. Maybe explore into areas that you haven't thought of before. The new system should bring better reception, and depending what part of CB you are in, it might be considerably better due to new tower construction. The PSR-800 is a very capable radio...you might want to wait for the new system to be built out before deciding to shed it.
