The swr into the resister climbs to about 2:1 on some parts of the band and is 1.5 on others. And variable twin PBT allows you to either narrow the IF passband, or shift the entire passband to eliminate QRM. All the controls are intuitive to use. You can choose from 3 background colors and 2 font styles to suit your preference, in addition to a large operating frequency readout. The AT-7000 works with any Icom radio that supports AH-3 or AH-4 Icom antennas.
Researching the units repair, I found it tedius to send in for what turned out to be a simple repair; The units controller chip, (a one-time programmable custom programmed IC), utilized an on-board A/D for SWR measurment without overload protection. The AT-7000 will tune all HF bands with the exception of the bottom half of 80m and all of 160m. I’m impressed!! Now to upgrade my ticket and I’m good to go! The same button turns the Compression On or Off also is used to adjust the Transmit Bandwidth Filter. Like other owners, I had the stock microphone reworked by AB5N.I’m sure most agree that to give an honest review requires ownership, not hearsay.
