- Local QRM reduction
- It is not always possible to tackle the sources of local QRM. What remains is trying to reduce the noise level by means of your antenna system.

- DSPBOX
- DOS Freeware, DSPBOX is an attempt to code the Texas Instruments DSK 'C50 in such a way
to make it behave like a commercial DSP noise reduction unit, like the
NIR-12, the TimeWave 599+ and others. Not only the noise reduction function
has been implemented, but automatic notch, AGC and Band Pass have as well.

Priority listing
- You will find on these pages my experiences and results on antennas and local/non-local QRM/noise reduction. Using a broadband vertical active magnetic loop and a home made / designed broadband amplifier. Two vertical magnetic Alford loops are used in an array.
Analog and Digital Signal Processing and a dual phase coherent Software Defined Radio (SDR) are used. By PA0SIM
