Connected a BME280 sensor to the #Meshcore transceiver Heltec V4.
SDA goes to GPIO 17
SCL goes to GPIO 18
Vcc = 3.3v
Needs some calibration 😄

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.

During the UHF and up #contest we made some QSO on 122 GHz (wavelength is 2.5mm) between #Netherlands and #Germany
RF power was only 0.5 mW (-3dBm) in FM F3E.
#QTH is JO21XC
Also #10GHz experiments

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

Indeed. Only 1 wire
You can add a resistor and capacitor as filter but rtty decoding works also without that RC filter.
