Some interesting stuff about the Baofeng BF-T1 that Ivan Hazelton shared* on the original BF-T1 post:
Good news! With the programming cable you can program this little rig with 20 channels 400-520MHz and 130-174MHz. Now be aware that the antenna is ... sub-optimal for the 130-174MHz so a suitable replacement will need to be MacGyvered. It'll be great to have a little, >$20, 4oz, disposable, dual band rig. It goes by another name BF-9100A, and the software to program it can be found here or direct linked here (.rar file). The cable does use a fake PL-2303 serial chip, so you'll also need the drivers off the same page, or direct linked here (.rar file).

Once the USB driver was installed I opened the 9100 software and changed the com port to COM3 since it was the only one showing as available and was able to read and write to the radio.
