Hi Mal,

I use a usb to rs232 adapter cable.

Mine is a Gembird UAS111 & I purchased it from a local PC outlet in Blackburn.
The makers website is www.gembird.eu

The ideal chip for compatibility is a Prolific PL-2303.

No other progs running, meter mid scale, cpu 2 Ghz seems ok, sound card CMI 8738/C3DX AUDIO DEVICE (C-MEDIA)  NO CONFLICTS

There seems to be a rx decode problem although the sigs appear on wfall

Win7 unltimate

Mal,

 

What  sound card  are you  using  ? 

 

Audio  meter  should be   round  mid   scale  

 

CPU  should  NOT be in the  RED

 

there  is no  problem  with the  level  of the signal

 

Any other  prog's  running  ? 

 

73- G,

hi GRAHAM

 

tnx info

strange thing is that I cannot decode ur signal which is weak but visible also PA0WMR very strong and audible. Both signs between red lines in  waterfall, wonder why no decode

what is optimum input reading on volume meter

need some other EU STNS further away for interest and long haul tests
