DRM - Reception logs | Kenwood TS-440 |
New test performed today in portable conditions using :
- Sony ICF2001D (with batteries) + its telescopic indoor ant
- IBM Thinkpad 570E
- 5600pF capacitors between RX ans mixer input
- Mixer outside receiver, with 9V batterie
=========================================
Todays conclusions:
- The noise caused by the computer supply/charger
is coming into the RX thru the soundcard connection.
Will have to work on shildering everything better.
=========================================
9H35 - RTL - Without
computer supply.
Very good results
