It will go into instantaneous meltdown and release amber to permanently seal in you and all radio frequency emissions.

Or it will give you an error message for out of band and not go into transmit. The antenna, depends. Worst case the mismatch will cause a very high reflected signal which will damage your output amp.

If it's a fairly modern radio it likely just won't transmit. My ICOM T70A just displays "OFF" when you try to transmit out of band. And of course it is illegal to do so. Since it will receive out of band I have a couple of marine channels programmed in that I scan along with nearby repeaters. Just for fun, because I was already sure it wouldn't transmit anyway (the manual says so) I tried the PTT button on one of these frequencies and that's what happened.

Some of the new low cost Chinese radios can be programmed to talk out of band if you get them direct from the factory. I believe they can't be sold in Canada or the USA unless this capability is disabled, but I might be wrong.

Just out of plain curiosity and nosieness, why do you want to transmit on 149 mHz which is a Federal area of activity?

Default Why 149 mHz?

I assume nothing. 149 mHz is not an amateur frequency anywhere. The band is 144-148 or 144-146
all over the world. My question was one reflecting curiosity, as I stated.

Default out of band

The Baofeng hand held sold on Amazon and a bunch of other sites is 40 bucks, dual band vhf uhf and transmits 136 to 170 something and the usual uhf spectrum without band lockouts. Pretty interesting radio really and works rather well.

He has this same post on QRZ.com. It is his only post since registering back on 7-9-12. His call sign is not listed on the PARA website. Not all of us assume such when his call sign is not a US call sign block.

It's a Philippine callsign for what it's worth. In any case having no idea what sort of radio he has nobody can answer that part. When it comes to the antenna at 1MHz or more out of band the SWR would be prohibitive, a radio's protection circuit would fold back power to little or none even if the PLL could be opened that far which in itself is doubtful.

Default commercial fisherman perhaps

Yea perhaps he's a commercial fisherman. The commercials use 2 meter radios much of the time that have the band limits removed, going up and out of the 2 meter band for their secret frequencies. Could be any of a number of reasons he wants to go where most people don't go.
