To quote Dave VE3KCL from QRSSKnights list:

I am the guilty one transmitting the glyph on 10 bands from a garden U4B solar and battery powered garden dipole.
The antenna is a 3 band fan dipole at about 15' so off resonant antenna penetration is quite poor.
Below is a snippet of the Basic code with tx frequencies.
The transmission frequency varies as the voltage level of the battery from every 20 minutes to once an hour.
