The CW beacon on FO-29 does still function. We are definitely fortunate that FO-29 still works and works very well. It is clearly the most popular linear transponder satellite due to it's wide passband and high orbit.
I would note that we are not starved for linear transponders. There are 7 in orbit and active and 4 in orbit awaiting activation plus at least one more scheduled for launch this year (Nayif-1). As far as FM satellites, there are three in orbit with two of those available 24/7 and a third with an errattic schedule. However, between now and January, three more FM satellites are scheduled to launch (Fox-1Cliff, Fox-1D, and RadFxSat/Fox-1B).
The issue, of course, is the orbits of these satellite don't approach the 1460km apogee or 1330km apogee of FO-29. We can blame debris mitigation rules for that! Hopefully we will find a way to get some higher orbiting satellites up in the future (including GEO/HEO).

This past weekend, I made three ARRL/AMSAT Field Day QSOs via FO-29 (JAS-2). Nothing noteworthy about that, except that FO-29 will be 20 years old on August 17th. We're very fortunate that its linear transponder still works. The CW beacon and digital transponders are no longer functioning.
Two more of the satellites carrying the bulk of amateur satellite communication are well beyond their design lifetimes. SO-50, our main FM transponder satellite, will be 14 years old in December. Then, of course, there is AO-7, whose linear transponders miraculously are still functioning some of the time. In November it will be 42 years young.
Educational and research satellites are well and good, but amateur satellite communication is still overly dependent on aging space hardware. To those who are building new amateur communication transponders, especially linear transponders in the UHF and VHF bands, best wishes for success. I wish there were more of you. Maybe there will be.
