ICE/ISEE-3 to return to an Earth no longer capable of speaking to it
From Emily Lakdawalla of The Planetary Society:
"So ISEE-3 will pass by us, ready to talk with us, but in the 30 years since it departed Earth we've lost the ability to speak its language. I wonder if ham radio operators will be able to pick up its carrier signal -- it's meaningless, I guess, but it feels like an honorable thing to do, a kind of salute to the venerable ship as it passes by."

The 64 m subnet is committed to support the International Sun Earth Explorer (ISEE-3) spacecraft. The uplink and one of the downlink frequencies will be respectively, 2090 and 2217 MHz. As these two frequencies fall outside the normal DSN transmit and receive bands, the 64-m antennas present new filter requirements, which are analyzed.

I have made a comment on the EME reflector about whether or not someone was capable of the contact. So far I have a couple of replies that capability exists. Now to do the math and see if it is a reasonable attempt.
