    ICOM IC 720a

    I just bought an IC 720a at a hamfest. It's in really good condition. My question is that when it is turned on, it takes a few minutes to come on
    and start tuning to the band..(the klacking sound). Is that normally how the 720's start up? Thanks.

    Yes. The 720 has a mechanical band switch that the microprocessor ratchets around with a solenoid. When you first turn the radio on part of its power on self test is to find the beginning of the band switch.

    Thank you for your information...I have been a tech for 15 years and I am studying for my general ticket. I am new to HF rigs so I just wanted to be sure.

    I have an IC-7072 interface that allows you to slave an R-70 to the 720(A). If interested, get in touch.

    The R-70 has better interference-fighting controls than the '720 does. With the EX-7072, you can control the '720's operating frequency by means of the R-70's tuning dial. It's like having two receivers in one.

    Go here and read N3WXW's review of the setup:
