BAOFENG UV 3R+ 144/440 Modified for 220 Mhz ?

Someone on Ebay is selling (what they call) a Baofeng UV 3R+ "Triband" HT that covers 144/220/440 for $50.  The exact listing is "Triband Radio transceiver (144,220,440) modified tri"

1. Has anyone modified any Baofeng for the 220 Mhz band?

2. What diodes needed to be cut?

3. Did anyone buy this "Triband" radio off of EBay and how is its performance on the 220 Mhz band?

4. Can other Baofeng radios be modified for 220 Mhz?

5. Is it worth taking apart the radio and doing the modification (if possible)?


Thanks in advance

It is not a hardware mod it is a software flash. I have a 220 to ten meter remote base and a local ham flashed his uv-3 for the 220 mod.  Only one problem is due to the transmitter matching components the radio will only transmit with ~50 milliwatts of power and no more, however the receiver performance is around.  .30 uV which is just fine.

Do you by chance have a link about this? I was planning on getting a Baofeng UV-5RAX for 220, but I might go this route instead, as I have a UV-3R laying around here somewhere...
