Unfortunately, we do not sell or support either model of radio that you have, so I am basing my response off of the limited information I was able to find online this morning.
I was able to confirm that the Uniden radios are a set of consumer radios that are designed for use in Australia and New Zealand. The specs say that the radios have 80 different UHF frequencies to choose from, but I was unable to locate a full list of what those 80 specific frequencies were. Either way, these radios may not be legal to use outside of Australia & New Zealand. This is something you will need to check locally if you are planning on using them elsewhere.
That being said, there’s really only one way to make these two radios compatible. You will first need to find out which frequencies are being used on the Uniden radios (I would suggest reaching out to Uniden directly for this information). Once you have the frequency information figured out, you will need to obtain the programming software and cable for the Baofeng model, and program the Baofeng radio to match accordingly.
I wish I had a simpler solution for you, but unfortunately, there’s not really an easier way to accomplish this with the two types of radios you have. Different types of radios use many different default frequency lists, so most radios are not compatible by default.
If you have any other questions, just let us know. Thanks!
