Put a t/r relay in the antenna, and switch the speaker. Remember to switch in a resistor load in place of the speaker. I think the SX-99 has 500 ohm and 8 ohm outputs, you might bridge a 680 ohm resistor across the receiver's high impedance terminals.
You should be feeding the receiver's 300 ohm balanced antenna input with a balun. You will enjoy a noticeable reduction in noise and increase in spurious signal rejection. 73 de Bill, ab6mt [EMAIL PROTECTED] ----- Original Message ----- From: "Bob Peters" <[EMAIL PROTECTED]> To: "AM" <[email protected]>; "Boatanchors" <[EMAIL PROTECTED]> Sent: Monday, April 16, 2007 2:03 PM Subject: [AMRadio] SX-99 Mute Hay guys does the SX-99 have anyway to mute???
