I searched the site for this and did not find it IRFZ24 SiHFZ24

This appears to be the final transistor being used by Yeti in the 485Dragon radio.

Digi Key has them for $1.50 in singles I am sure it drops the more you buy just like Mouser. Since the search function did not turn anything up I thought it would be good to start this one.

Mouser shows it as "844-IRFZ24PBF".

Buck apiece if you buy ten.

All the ratings have to do with using it as a switch. The specs say nothing about using it for RF.

Gotta learn how to translate the switch mode specs to RF-amplifier performance.

I hear you I feel like I am taking 2 steps back for each step forward. It is truly confusing to a shade tree electronic hack like me. LOL Right, when I think I have a clue I get confused! LOL Lucky for me I learned how to laugh at myself and most of the world while very young! LOL

http://www.vishay.com/docs/91076/sihf9530.pdf This is the IRF9530 what do you think about it? Also take a look at this one IRF9540 it is showing a dissipation of 150W's and is T-220AB package. Obviously, it is not listed for RF use.
