FM Satellites consume much more energy than a linear satellite.

FM is 5khz wide at the very most. How many SSB transmissions can you fit in one 5khz slot? Two, easily without each operator stepping on each other. 

Instead of transmitting 20 watts ERP on FM to have a near noise free uplink/downlink, a few watts SSB, CW, SSTV etc would make better use of a satellite and it's resources. 

If you were to channelize one or two birds with 3 channels each, the life span of those birds might be half that of the rest of the fleet that is always zooming over our heads. It would be "nice" for a while but a waste of resources. I suspect that we would still have those that would monopolize the birds....but you have that anywhere on ham radio too. 

I'm new to this satellite operating...only a little over a week into this. I tried many years ago to listen for ISS but was unsuccessful and didn't have the time or resources to track ISS and everything else in space. I didn't realize it was so easy to hit a satellite with an HT and a portable directional antenna, but there is more up there ....just wish the gear was not cost prohibitive in some cases...but baby steps!

If I can't always make a contact, I just copy down the call signs that I hear and their grid squares. That is a thrill all on its own when you look to see where everyone is located.

My daughter's are fascinated that one can talk to the hams on ISS. What was icing on the cake for them was one night ISS passed over head...it was a week ago at night. I had my HT tuned in and was listening. I even tried to make a contact but 10 watts, a rubber duck antenna and a busy night as ISS flew over...I don't think anyone heard us, but my daughter's were fascinated to see it zoom by over head and hear them on the radio at the same time.

That is what part of the hobby is all about.

So why not channelize the next gen of FM sats so there’s more than one channel available per pass. That would spread the users and reduce the congestion. And while we’re at it, have a dedicated rover channel where only rovers throw out callsign and grid and all others are responders, not initiators of QSOs.

Mark,

I totally agree. Sharing is the main issue that isn't happening enough
on "the Easy-SATs". The experienced Rovers are well aware of NOT
hogging a pass and they try to avoid doing that. But, they can't help
when a pileup ensues when they are at a rare location. And, there are
many Chasers that only have FM capability and they need to be
accommodated, as well.

It's just the nature of having a single-channel resource that can be accessed
from much of NA and possibly thousands of Hams at the same time. Only
one signal can get in and be readable at any moment as we know. That is
pretty much the formula for chaos and mayhem.

I don't claim to know what the solution is, but trying to prevent certain
users from having access to the SATs they support is not it.

Not suggesting the sats should be "off limits." I'm suggesting that users should be courteous and welcoming to others, especially newcomers. That means not hogging the bird.

My comment still stands. Making SATs "off-limits" for "certain users"
for "certain reasons" makes no sense and couldn't be enforced. Besides,
those users are just as much AMSAT Members as everyone else and 
have been the biggest supporters for many years. My 2 cents.

What is the primary reason we are all working for the good of AMSAT?

"To build satellites, and to disseminate information about them to the planet.”

We’re not a “contest club.” That’s icing on the cake for those interested. 

We need to welcome those new to this aspect of the hobby. Give ‘em prime time. 

Working only five days a week - during less-trafficked passes - would be a blast 
for award-seekers.

them the most.
