"R. Ton" <[EMAIL PROTECTED]> made an utterence to the drakelist gang ---------------------------------------------------------------------- Just a quick note... Man, what a difference! I found a pair of 1-ohm 1-watt resistors. Still have some problems that indicate that the T/R relay needs replacing so have just placed one on order. I'll leave the radio off until that arrives, but I can tell already that this is the right track. Many thanks!
