When radio-amateurs make world-wide contact, both sides confirm this connection by sending "post"-cards named SQL-cards, stating the details of this event (transmitting frequency, power, type of transmission, date/time and more..)

I found a font used by a print-shop that I want to use also, but after days of trying to find this font, I'm out of ideas.

My interpretation of this font is a font with a glow, shade and slight depth effect but no luck so far. Any ideas

Looks kinda like Boris Black Bloxx by Manfred Klein.

Unbelievable ..... I think you are spot on. Thanks for your help. Very much appreciated
