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
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。

Yes, the uplink frequency is 1267.603MHz.
Up 1267.603MHz / Down 437.475MHz, GMSK 9k6
Unproto APRS via JQ1YTC

 Up         Down
1267.576   437.484  AOS
1267.603   437.475  TCA
1267.630   437.466  LOS

CO-65 continue doing ON of a transponder all the time
for these periods in March 2009.

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.
