Is there anyway to interpret the frequency range of these radios just by looking at the radio?

According to the Icom website...136 to174 mhz for VHF F-11 radios
& 400 to 470 mhz for UHF F-21 radios.....software program is the same.

Well that part I knew. But for UHF it's not 400-470 continuous though. It's split in 2 ranges. 400-430 and 440-470. And I was wanting to know if there's anyway by looking at just the radio to determine what range the radio covers?

Thanks for your earlier response.

tactcomm easier to go to ebay and for about $20.00 get either a 9 pin serial or USB cable.

n8dhw, there is no real way just looking at the radio, you can call Icom and have them look up the serial number, but for the most part, since 400-430 is goverment use you will find that most of these that you find will be the 440-470 split which will cover ham and commerical.

Are you looking at some?

I'm looking at this one on EBay 251190758443. I sent the seller a message and he thinks its 400-430 but didn't sound sure. That's why I was asking if there was anything identifiable on the radio itself that would tell me.

Thanks

Get the seller to send you a picture of the label on the back of the radio.
On that label will be the FCC ID number.
Take that number and go here: http://transition.fcc.gov/oet/ea/fccid/
That should show you the frequency range for that radio.

He has a picture of the back of the radio in the listing. I will look at it and try your link. Thanks

Good radio, but way over-priced without an antenna. The F11/F21's also have an issue with the battery contacts going on/off in high vibration applications.

Look at a F43 like 190781317152- you would be much happier. The -86 version is for 380-430 military apps, and won't cover GMRS, The common splits are 450-512 and 400-470. Both will do what you need.
