AMEN brother!

I called CQ multiple times on AO-7 in CW last night between 145.940 and 145.944 (downlink), and NOBODY was tuning down that far. I found that very disappointing, as I did the close proximity of all the stations on FO-29 and VO-52. 

I believe a lot of us could have made a lot more contacts on the linear satellites if we'd just used the passband.

Thanks for this post Drew!

73 to all,
