hi,
thanks to all responders .there are three on the same board.the model is a th-26 handheld 2m.i've checked all the surrounding resistors and nearby passives .i think its a power supply problem.i dont want to power it up yet until i find out what this part doesi dont want to take another one of these ants lol out and check it out of circuit.smt is not my thing.i've searched for a free schematic so if anyone out there's got the schematic that'll be great .i'll take on board what you guys have said many thanks for taking the time.
