A quick google suggests the ST4148 is a zener diode but I think it's as everyone says a 1n4148 100V 1A rectifier. The datasheet says 1V Vf. I think the ST prefix probably indicates the manufacturer?

I'm going to have a look in town on wednesday while we are in and I might buy one out of curiosity. If nothing else I think it could be possible to mod it with a variable capacitor and I might see if there are any strongish signals here in the frozen wilds.
