  Sorry for late comment.

  In the middle of this January, I QRVed on UO-14 from KH2 Guam and
tried to watch how the QRM comes, with my friend in Guam who can
understand philippino language.

* QRM was when the UO-14 was just over YB area. But It was not so much
  strong. I can pass my voice with my 40W uplink with 6ele Yagi.
* When the UO-14 comes over DU area, QRM became much heay! My friend
  said that these QRM might be come from telephone-use of inter-province
  communication at the local area of DU.

  I tried to access the UO-14 when it was at the east of Guam, and
much surprised "How iteasy to access!". My 5W uplink with 6ele Yagi
was much enough for access. I did not try with my ruber-duck whip
but it might be could Hi.
  Now I can understand why the VK hams can talk each other via FM birds
with just HT and whip. The problem is only "QRM" on uplink.... x-p

  I also tried to send APRS packet from KH2, but due to my PC setting,
I could not confirm that my packet reached to PCSat or not... Hi.
