Baofeng BF-T1 (BF-9100) on Facebook

"1. When using the amateur radio band of 70cm, then the 2nd harmonic is approximately -30dBc (dB relative to carrier). No detectable 3rd harmonic.
2. These radios appear as though they can be used on the 2m amateur radio band, by going into the programming system.
HOWEVER! When transmitting on 2m. The fundamental is very low and the 2nd and 3rd harmonics are GREATER than the fundamental. Therefore I conclude that these radios must not be used on frequencies, different to those stated by the manufacturer."

BF-T1 measurements via SDR dongle (so take them for what they are worth):
"I have received and programmed the Baofeng T1 but i may have some problems with it. While it works correctly in the UHF it outputs only very low power in VHF."
I agree with Jim:
"It isn't designed to TX on VHF. You should only program VHF frequencies for RX only. For example NOAA weather radio reception."
You can pick one up for cheap on Amazon:

Baofeng BF-T1 (BF-9100)

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)
Direct link to BF-9100A/BF-T1 Manual (.doc).
Also, it has CHIRP support.
