今のところ CO-65 GMSK 9k6 digipeat に成功しているのは日本だけのよう
です。外国でも追試が行われていますが、まだ成功した局はないようです。
今朝(Mar.1) のパスでは、自局を含め 3局がデジピートに成功しました。

When it is the elevation more than about 30 degrees,
you will be able to digipeat your GMSK signals.
And you need to give power more than about 10 watts,
and it's necessary to use a pre-amp for downlink
because the output power from CO-65 is 300[mW].
This is VERY VERY weak output power from CO-65.
