I've never used CHIRP and I am very confused. I just purchased a JT270M and can read from radio to CHIRP, but not write CHIRP to the radio. Jetstream advised me that CHIRP and the 270M will not work with WIN 10. I will not get into the quality of support from them in this section.

I do have a machine with WIN7 on it and I get the same issue. I did get the VV898 software to load the 270 M ( 1 test freq)but with errors (No ALPHA Tag). Jetstream suggested a different prolific driver, but as of yet, nothing has been offered to me from them to use. I am fair with computers, and I wish to determine the following:

1) Which OS to use

2) Which driver do I use for the prolific driver (USB w/chipset)

3) Any other suggestions that you may have.

Thank you!
