Hello.. Recently I purchase a pxton 2 way walkie talkie on amazon to use on a trip and I need some guidance in regards to reprogramming the walkie talkie.
I change the frequency from the factory setting VHF to UHF 400-470MHz with the two software, 888S and BF-480.
Through my trial and error I notice something strange and I can't seem to figure it out. Google search didn't help.
1. When I use the 888s software to change the frequency from VHF to UFH, 400-470MHz and change all the channels to FRS channels, I get a scratchy/static noise when I turn on the walkie talkie. It sounded like a tv channel not receiving any signal like in the old days. I can communicate with one another but you can hear static noise on the background and when the walkie talkie on standby mode, it has the scratchy noise. I play around with the squelch level and it didn't help.
2. On my 2nd trial I use the software that came with the walkie talkie, BF-480 (Chinese version), I program it exactly as above and it work.
No scratchy noise when turn on or on standby mode. The communication is clear, no static.
Now the strange part is when I used 888s to read the walkie talkie, the reading came out differently see below.
Here is a screenshot of the setting with BF-480, notice that it is set to UHF with the frequency between 400-470MHz.

Here is the reading I get from 888s software after the walkie talkie has been reprogram with BF-480: The frequency range shows VHF 2 (245-246 MHz)
I don't understand why the Freq Range is showing VHF2 on 888S, when the walkie talkie has been program to run on UHF 400-470MHz as shown above.
Since I am getting different reading, I do not know if my walkie talkie is set to run on UHF 400-470MHz frequency or VHF2 245-246MHz.
Any insight or suggestion is highly appreciated. Thanks in advance for the help.
