Welcome

Yet another site about Ham Radio. Mainly with information about my 'Home Brew' stuff
... and some useful information (at least for me ;-) with links to other sites.

Some content specifically meant for local use is in Dutch

FT8 HF transmit power PA0ROB

On the HF bands PA0ROB always uses 5 Watt transmit power.
In this way I can compare different broadcasts over time.

Never say never (or always). In special or rare occasions I may reduce power.

Fan Dipole for 160m-80m-60m-40m-20m

In this new version of the Fan Dipole, the 160m band must be included... (for many decades the lowest radio frequency band allocated for use by amateur radio)

Main goal is to end up with a fan of resonant dipole antennas on all the included bands.

My garden is to small for full-size 80m and 160m band dipoles, so I had to shorten and or fold (and even combine) some dipoles.

NLX204 op een Raspberry Pi 4B - 4GB

Vanaf begin 2020 draait NLX204 (was MMX411) op een Raspberry Pi 4B - 4GB.

Met name de afhandeling van de diverse dashboards gaat hierdoor merkbaar sneller.
