It seems you have to let the carrier going down and give you reply after meaning having to exercise a strict discipline on that sat and my 
guess is it will hard to achieved on this FM one channel sat... When someone is calling another station don't transmit and let the exchange 
process completed before calling or answering someone else.

I don't agree with the idea that an FM one channel LEO is better than a transponder one. On VO-52 we can have up to 10 QSO'S on a single 
pass at the same time. On a FM repeater satellite it is only one at the time and SO-67 is attracting more users as he's much more powerful 
than the other cube and numerous new-comer get on with dualband mobile rig with no headphones resulting in a lot of feedback loop.

It is an entry sat as probably the next one! Could be frustrating sat will be a more appropriate name... ZOO sat can also fit very well and 
if SO-67 usage does not come more disciplined he will never be an easy sat but a hard sat making quite impossible to have some sort of any 
decent short chat other than callsign/report/grid exchange IMHO it is not what someone who want's to work on the sats need. I still does 
not understand the AMSAT-NA one single channel FM sat project. There is already very small tranponder board available made by William 
PE1RAH 
Why not using one on the next AMSAT-NA satellite?

P.S. One of William transponder is actually on VO-52 with another one YES 2 transponder on the same sat! Is it possible to have some sort 
of combo on the next AMSAT-NA project no need to have fancy toys just plain transponder and FM cross band repeater on the same cube both 
options will be satisfied as they can be activated in alternance as AO-51 is working actually.
