HAM radio station - Veldhoven - JO21QK
FM DX

The FM band in my area is very crowed and even more powerful transmitters have entered this band last year. All available frequencies are occupied.

Maybe region Eindhoven has the highest populated number of FM transmitters of the Netherlands. Serious tropo DX is no longer possible.

So it’s time to focus on another part of the radio hobby.

A thunder strike destroyed my preamp. Only the ATF 54143 has been broken and replaced.

It seems that SMD becomes smaller each year. Or do my eyes decrease?

91.1 NDR Steinkimmen without preamp.

91.1 NDR1 Steinkimmen with preamp. Better signal/noise ratio.

BNR radio is the only station here using DARC around 75kHz.

It seems to be used by local public transport to inform the passengers on remote signs.

Another fine tool to predict planescatter and it works. This is my reflection to 96.6 SRF2 Rigi.

SDR-radio now supports Perseus SDR. The WFM filters works better than FM+ software. Also
Stereo and RDS decoder included with AF (alternative frequency).

The Geminids peak. With the tool MS Effectivity I can find the best reflection time and QTF.

SpectrumLab works much better as w-fm demodulator. You can make your own filter and IQ setup.
I prefer SpectrumLab over FM+ when digging in the mud or splatter ruins the DX.
