Tonight I was successful in getting the L/U digipeater on CO-65 to respond to me, but was not able to decode it despite 10 over S9 signals at TCA. Uplink was UISS to AGW Engine to my KPC9612, IC910, KJ6KO amp, with about 30w at the antenna, a M2 35 element yagi. I'm interested if anyone outside of JA has had any luck with this, and what was being used to decode it?

The UHF and VHF uplink and downlink use GMSK modulation:
CO-65 GMSK 9k6 digipeat
GMSK is now scheduled on every weekend over the world wide. You can digipeat via CO-65 GMSK 9k6.
In Cute-1.7 + APD II, we provide the following services using 1200MHz uplink and 430MHz downlink, on a trial basis.
1. Real-time relay communication service 2. Message box service
1267.6MHz high-speed packet communication (GMSK-9600bps) is used for uplink. 437.475MHz high-speed packet communication(GMSK-9600bps) is used for downlink.
The GMSK modulation is used in the D-STAR radio with the AMBE codecs i don't know if the CUTE data can be decoded in the digital data frames with the Icom D-STAR radio?
