I too totally agree. I see no reason why we can not vote on the designers decision with our support dollars. Personally, I am giving all mine to P3E.
The fact that they are "designing the ground equipment too" is of no comfort to me. My S band gear is on the tower and operating.
If AMSAT thinks this is such a great decision then let them find the money to support it without the majority of us.

Rick,
I am in _TOTAL_ agreement. I live in the suburbs of Tampa/St. Pete and never had an interference problem on my 3 foot dish. I have used the same dish to log well over a dozen WiFi access points in that immediate neighborhood. With properly designed equipment, all that trash on 2.4 ghz goes away with some elevation. What won't work is helixes with multiple sidelobes, and surplus dishes that let one whole polarity of noise right thru the back.
Everyone knows I'm a big supporter of AMSAT, but I gotta call it as I see it. It makes me think of "bait and switch" to collect money for a project featuring such a popular mode and then drop it.
The loss of Mode B on AO-40 caused a lot of the hardcore AO-10/AO-13 types to walk away, and that was tough to overcome. Now that we have, and we have people wanting S band, we leave them behind too. Even if it's a sound engineering decision (and that hasn't been proven to me) it's a horrid marketing decision. Bad mojo for a organization that lives on the donations of it's members.
Sorry if this causes any pain to those involved with Eagle, but I needed to get it off my chest.

While AO-40 was still alive and I was working it from deep within "Silicon Valley", an area blanketed by WiFi, 2.4GHz cordless phones, etc., I discovered that a parabolic dish with a properly positioned and designed patch feed (slightly under-illuminating the dish and having no significant side-lobes) would bring in AO-40's S-band downlink very nicely and cleanly.
Of course, other feed or antenna types such as helical antennas/feeds were useless in that environment.
I have to admit that I don't buy the "too noisy" argument.
