    It is also best if you can use PTT keying, Instead of RF keying.

    Yes, I understand the TX/RX relay will eventually quit working due to hot switching when using RF to key the amp.

    Another issue is using them on heavy duty cycle modes, such as FM, at full power.
    I ordered two 4" muffin fans to resolve that concern.
