While your local repeater has not seen the need for using newer advancements, others now have transistors, Phone patches, Microcomputer controllers, Voice mailboxes, IRLP and/or EchoLink access, RF backbones for linking, remote bases ...
I understand keeping what works but that does not mean that we should not explore new possibilities at the same time.

Interesting to note, our local repeater doesn't see the need to continually push the envelope, yet when we put one on a spacecraft, we seem to need the latest technology, not always available to the ham that just wants to go out in the backyard and operate without having to spend umpteen dollars to build up a station. Like the guy working HF with a simple transceiver and a vertical, some of us just want to operate and don't have the time/interest/money to spend building the station it requires to work some of the more exotic modes. I haven't seen any L band radios in my price range and S band seems to have lost interest (even though I'm told it was pretty simple to get on to)

This is intended to be an honest question that I've wanted to ask, but I don't want to spark controversy or long threads that monopolize the reflector. I have a feeling this could go either way, so I'm just asking politely that the thread not go that way! It's not my intent.
Anyway, I'm just curious why it seems that every new satellite project proposed seems to be bigger and more complex than the last? I keep hearing about exotic modes and uplink/downlink bands for P3E.. software defined transceivers, etc. etc. and what it looks like to me are more and more failure points. I understand the need to push the limits of technology as a justification for our very existence, but personally I feel like the designs are overly complicated and highly priced. I'm not ready to switch my earth station to SDRs, for instance.. I'm dubious about putting one into orbit.. then again, I'm not skilled enough to make those sorts of decisions.
What I'm getting at is that Oscar 7 proved how reliable older technology can be.. For the price of one of the phase 3 birds it seems like several Mode B linear transponder sats could be put up, or a few more FM sats. I personally would much rather see a modest mode B sat in AO-40s intended orbital pattern than to try to wrangle parts for microwave.
Did it get too easy for people or something?
Wouldn't it be better to separate out some of the more experimental stuff from the old standbys? That way a failure of one whole sat would still leave something usable for the same money spent. My vote would be to piggyback a completely independent analog satellite onto P3E "just in case".
Like I said, please, I'm looking for a real, thought out response.. I didn't write the above to be a critque or to troll or anything like that, I am just curious because it seems to me, as an outside observer, that after the failure of AO-40 the direction was to go bigger and even more complicated, which left me cold considering what I had done at my station to work AO-40. Even when AO-40 was up I felt it was very odd that time and money were spent on components and systems that were never used (did the solar panels ever deploy?) Yes, I know the sat was damaged, and that explains a good bit of it, but it still felt like some things were wasted. Emphasis on "felt".. I couldn't know the real process that resulted in the decisions made.
If someone could help me understand why the direction is the way it is maybe I could get excited about the bigger sats, but I think you get more "bang for the buck" with the smaller less complicated birds. My favorite so far is PCSat I. Mostly off the shelf hardware and I had a very easy time digipeating APRS through it. One of those in an elliptical orbit would be a hoot!

P.S. - One last plea, this isn't a troll! I'm worried people will think it is.
