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.

See if there is something that helps here.

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.
The purpose of life is to live it, to taste experience to the utmost, to reach out eagerly and without fear for newer and richer experience.

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.
Thank you... I will check the site out. 73
I have an IC-7072 interface that allows you to slave an R-70 to the 720(A). If interested, get in touch.

Slave an R-70 to a 720A means what exactly? Thanks...73
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.Originally Posted by K8TAE
