I have got like 6/10 DS10 that are out of range of RFXCOM even thou they are only like 10metres away.

I asked bert and he mentioned that DS10A The 310MHz sensors use a cheap transmitter that is not crystal controlled and they transmit sometimes far from the 310MHz center frequency.

so I'm wondering do i swap them out for the 433.92 equilvalent or just mod an external antenna.

question is, does anyone have an idea how to mod?

Hello ,

Here you can see the mod of a ds10a to 433.92 (dutch)
if you are planning to mod some off these ds10 i can made a tranlation for you.
But the pictures are speaking for them self (i hope)
