Sure is , The ATAS-100 does not work on 80 meters. I am including an 80
meter Comet QE Antenna...You should know this if you are using an ATAS????

N4ATS

Oh, by reading the Subject line, I was under the impression that you were
highlighting the 80 meters band of the radio. I didn't really read the list of
things you have for sale. BTW - I'm not using an ATAS. I use my FT-100D at home
and only on VHF/UHF.
