If the performance are to low, then you have probably a failure on the input filter Sun, 02 Jun 2013 16:04:10 GMT tonyvanacker http://uk.groups.yahoo.com/group/pmsdr/message/1729 http://uk.groups.yahoo.com/group/pmsdr/message/1729 After 3 days of testing and again testing I not cant get any higher then 2.1.8 firmware The recieving in compare to my icom pcr1500 or my kenwood ts-480sat on Sat, 01 Jun 2013 09:41:05 GMT Martin Pernter http://uk.groups.yahoo.com/group/pmsdr/message/1728 http://uk.groups.yahoo.com/group/pmsdr/message/1728 Hi group, we can use theLibUSB-Win32 USB Drivers for Win XP/Win7  also under Windows 8 without modifications. here a brief summaryto install the driver Thu, 30 May 2013 04:00:48 GMT Jonny Dingo http://uk.groups.yahoo.com/group/pmsdr/message/1727 http://uk.groups.yahoo.com/group/pmsdr/message/1727 Thank you, Martin and Daniele for your assistance.  It's not very bad really, but some of the stronger signals do get mirrored, as I think both of you are Wed, 29 May 2013 15:00:20 GMT Martin Pernter http://uk.groups.yahoo.com/group/pmsdr/message/1726 http://uk.groups.yahoo.com/group/pmsdr/message/1726 Try to press S2 and plug in the USB cable.

You can maximize the image suppression  in HDSDR (or Winrad) with the Wed, 29 May 2013 08:56:08 GMT buzzatronus http://uk.groups.yahoo.com/group/pmsdr/message/1722 http://uk.groups.yahoo.com/group/pmsdr/message/1722 I am encountering signal harmonics in the 10 MHZ range. The amateur 30 meter activity is often mirrored from 10.150+ thru about 10.230 MHZ.
