What do radios do? - HTC EVO 3D

I just need to know what does flashing a custom radio do?! Will this make my signal strength on my phone better and faster?

I don't think there are any *custom* radios. Radio images are very low level and very few developers pose the background/knowledge to correctly reverse engineer and modify.
On the forum, people post "custom" .zip files which contain different versions of official radio.img files.
Personally, I rarely update the radio.img as I generally just don't bother given too many other things to do. Some people notice an increased signal with a newer radio version, some people notice a decreased signal with newer radio versions.
Hope that helps!

Yea, radios can either help you, or make it worse, and most radio updates happen with normal ota releases,
And those normally get thrown into custom roms as the devs release new versions, etc

actually, majority of ROM releases, at least from what i've seen around the XDA dev board do *not* include a radio update in the actual ROM release .zip file. I know cm definitely doesn't and I'm pretty sure myn and xhausx do not.
Generally, in the ROM OP there will be a link to a radio thread where somebody maintains either the actual radio images inside of flashable .zip files or maintains the links to these files.
I have such link in my ROM OP thread pointing to a CDMA radio thread: http://forum.xda-developers.com/showthread.php?t=1193101

Radios work differently for different people. It usually depends on where you are located. You can try different ones to see which works best for you, but some custom roms will specify the best radio for that rom.

Just thought I'd throw this out there. Flashing a radio is a good way to potentially brick your device. Always be careful and make sure to verify the md5 checksum. Also make sure that the radio is for your device as in cdma or gsm. Flashing a gsm radio to a cdma device will brick your phone and vice versa. There is little to no margin for error when flashing a radio, reading the users feedback may or may not help but I always recommend it.

so as a general rule of thumb, is it a good idea to be up to date with the latest radios or not?

my personal opinion, since the risk is high and i'm fairly busy with other projects, i don't worry about being as updated on the radio as i do other components .. although, everybody is different.

If your experiencing slow/data speeds, unclear phone calls, sms or text msgs are slow to send and receive or your signal keeps switching from 3g to 1× are some of the signs of a radio that might need to be downgraded or upgraded. Radios work different according to area, cell tower location, distance and also network availability. Also take into consideration that hardware and software also play a role in how effective a radio upgrade or downgrade would be, as in mods or kernel's flashed or changed threw various other methods of modifying ones phone be it done by the rom flashed or the roms user. Its good also to keep in mind that any particular radio will do wonders for some and be a waste of time for others. It just a dangerous gamble. Its the one true time were you are truly putting your device at risk. Don't get me wrong if done properly the procedure can be excuted rather quickly and successfully. However the risk should not be taking lightly. The reason why I post this is Ive seen what a wrong or bad/corrupt radio can do and trust me its nothing you want to experience. So I'd suggest just setting some time aside to read upon how to flash a different radio for your device cdma/gsm and the correct method according to how you unlocked your phone as in team win or htc's unlocked method. As far as is it necessary to always stay up to date with the latest radio well it depends on you and how your current radio is performing for you and as I previously posted its always helpful to read the users feed back on the radio. Hopefully this helps somehow.
