Thanks
 

Lotsa times it is the Key Up Transistor that fails in radios. One of the little small 3 legged black moon shaped things. Don't ask me which one it is in a 2510. Someone else here will know.

Good luck
 
I sure would like to know what one that is. Hope it is something simple like that, but when I key up it don't even close the recieve, it still recieves when I key up ot cross the mic pins... I know what pins 4 & 5 Does! channels..

Please help
 
Impatience and radio doesn't mix well. It is a decent radio that is worth getting fixed. Send it to a shop, like Roger Bird if you can't fix it yourself. He is 'da man' when it comes to these radios.

If you want to look at the schematic and figure out where the keying transistor is, here is the Service manual & Schematic link:
