Local #interference makes #reception below 5 MHz impossible.
But this solution with a miniwhip #antenna and mixing this signal out of phase, the #QRM is almost gone.

March 3th 1980, it was legal to use #CB #radio in the #Netherlands.

In the first weeks, more than 300000 licences were sold but only 22 channels were available.

The result: very crowded channels.
Hear the mess of #channel 14.

With this mod, you will have a #RTTY #decoder
New is the terminal #display to have a larger read back window.

#conditions are bad today but here is a small #demo with Pinneberg #weather #station

There was a time I really loved it.
Hearing signals from westcoast W7/VE7 via #longpath

Greyline around December 14th.

Forever gone

In between some appointments, I stopped near a small forest for a #test in a #QRM free area
There only was some QRM from the #SI4732 itself but I could #decode #Pinneberg good on #longwave 147 kHz

Have some time to install the newest #firmware on the #SI4732 #radio

This video shows #RTTY decoder of Pinneberg #weather station at a speed of 50 baud on the 30m band.
