I have ordered the transistor and capacitor for my texas star dx 500. Once I replace these is it safe to test the keying function without being hooked up to the radio just to check it? Thanks again!!

Got it! Thanks for being so helpful to me and my lack of experience.

Thank you again!!

This is top of pcb board?

Thank you!

Thanks.

Thank you nomadradio

Thank you for the reply. I don't know much about schmatics. Can you tell me the name of the part each final pin goes to? Thanks
