Upload new #firmware v2.11 into the #ESP32 #SI4732 mini #radio toy. New features on #RDS (RT, PT, PI) and freq database (#SSTV #FT8 #CB). Still no #CW as mode available but bandwidth at 500Hz is selectable. #hamr #hamradio #AmateurRadio #arduino #software #antenna #FM

The #SolarPanel inverters are working full throttle this time of the year. No #emergency #communication possible. "Your antenna is interfering my TV!" #hamradio #hamr #AmateurRadio #radio #interference #QRM #solar #GSM #4G #5G #WiFi #police #ambulance #FireDepartment

Playing around with FT8CN on the #Android #phone and #QMX #QRP #transceiver Seems to work for #portable use First make the mandatory #FT8 QSO for valid operation before #CW and #SSB fun starts. #hamradio #hamr #AmateurRadio #POTA #SOTA #WWFF #antenna

Installed v2.20 #firmware on the #SI4732 #radio The most useful new feature for me is direct #frequency input by pushing (hold) and turn the encoder dail knob. #hamr #hamradio #AmateurRadio #antenna #HF #shortwave #software #cheap #portable #SOTA #POTA

How compares a cheap #SI4732 #receiver to the legend #Belka ? Let's go to this nice place in the #forest away from #QRM sources I was able to hear weak #signals on the Belka (Q5) but absolute nil on the SI4732 Also nothing on my #kiwiSDR at home #hamradio #AmateurRadio #hamr

Compare noise level #SI4732 vs #Belka #radio #receiver SI4732 starts #receive at around -125 dBm and Belka -135 dBm Also much more birdies on the SI4732, hard to find a decent clean #frequency #hamr #HamRadio #AmateurRasio #measurement #HF

A new #firmware (v2.23) for the #popular #radio #SI4732 is just released with again some nice features. #FM de-emphasis (on region). All #RDS #EEPROM #backup And nice new #signalisfanart and S/N #meter #hamradio #hamr #AmateurRadio #WiFi #arduino

Building the #QRP labs QLG2 #GPS receiver for my QMX transceivers. Let's do some #WSPR test with these devices. Already a good 3D fix inside the house. #hamradio #hamr #AmateurRadio #SOTA #POTA #WWFF #portable #antenna #HF #propagation

Bad #HF #propagation So playgeound time and connecting the #Belka #receiver to HDSDR. Please use an 1:1 transformer to protect the receiver. Just in case. #hamradio #hamr #AmateurRadio #SDR #radio #IQ #computer #software
