Good Tropo conditions on Friday July 23rd, 2021 on 144 MHz.

Reception of the beacons IQ2MI in JN35WW (first time heard) and OY6BEC in IP62MD.

Beacon reception 23072021

IQ2MI-BIQ2MI/B is the Europe highest VHF Beacon, located at “Capanna Margherita” refuge, at 4560 m asl. The power is only 500 mW into a dipole !

Below, you can hear the recording of the beacon received on July 23rd, 2021. There is a transverter 144 > 28 MHz in front of the FT-857, so that the “real” frequency is 144.415 MHz, not 28.415.

Morse code translation :
V V V de IQ2MI/B JN35WW BAT 13.82V SUN 14.03V TIN 29C TOUT -32C www.arimi.it

Message format :
“V V V de IQ2MI/B JN35WW BAT nn.nnV SUN nn.nnV TIN xxC TOUT xxC www.arimi.it

VBAT = battery voltage
VSUN = photovoltaic panel voltage
TIN = radio box temperature (°C)
TOUT = external temperature (°C)

You will hear that there is another beacon on the same frequency, it is DB0JW in JO30.
Well, I have some doubts about the outside temperature… -32°C mid day during the summer (even if the altitude is high) ?

Now, heading north to the Faroes Islands, the 2m OY6BEC is located in that radome, in IP62MD :

OY6BEC-B
