At one time the original Kenwood D710 has the possibility to add a keyboard.
It was the TM-D700 and Kenwood missed the mark with the lack of PS2 capability on the TM-D710.

John Hansen at Coastal Chipworks had a keyboard adapter for the TM-D700, but never one for the TM-D710.At one time the original Kenwood D710 has the possibility to add a keyboard.
I'm sure there is, you could do something like how Ethernet (or AlohaNet which is even more applicable) works, but it only goes so far...
There are also the transmit-only nodes, what should be done about these? Also if there are more than one weather stations within radio range, which one gets which slot without coordination?
Definitely time slotting would help, but yeah, it depends if that node also has a receiver. The nodes that have receivers could work with the transmit only nodes (btw, that would be interesting, is there a bit in the spec that tells whether a transmitting node is transmit-only? That could be useful to help work around collisions.)
DCdconn ON|OFF Default: OFF
OFF RS-232 cable Pin 8 is permanently set high (default).
ON RS-232 cable Pin 8 follows the state of the CON (or DCD) LED.
DCDCONN defines how the DCD (Data Carrier Detect) signal affects pin 8 in the RS-232 interface to your computer or terminal. Some programs such as PBBS software require that DCDCONN be ON. DCDCONN also works in the RAWHDLC and KISS modes. In RAWHDLC and KISS, no packet connections are known to the PK-96. With DCDCONN ON, the state of the radio DCD is sent to the RS-232 DCD pin (pin-8). This may be necessary to some Host applications that need to know when the radio channel is busy.
