How to make the receiving or transmitting distance of the walkie-talkie farther? I have a small PHS smart relay station from PHS. Can it be converted into a walkie-talkie relay station?

If you change it, then you are a master, a master, a master. First, the modulation method of PHS is different from that of walkie-talkies. Second, the frequency of PHS is around 1.8-1.9GHZ, and the bandpass and PLL of walkie-talkie relays are around 130-470MHZ. Third-party software is also not compatible unless you have superb software programming skills. Based on the above, if you want to change it, your monthly salary should be no less than US$100,000 per month. What I’m talking about is not that you throw away the circuit board inside and put two walkie-talkies in it and it will be converted!
