I found these circuit diagrams for VHF transceiver online, and am having trouble recognizing a number of the symbols. Would you please help me identify the boxed symbols?
Here's what I've got so far:
Drawing #1 (original image link):
The red box with CLK should refer to clock, but I don't know which type or if it even matters. Completely clueless on the blue box with L12.
I think that the red boxes labeled CuAg and CuL are likely wire coils of copper/silver and enameled copper wire respectively. The blue box appears to be a transistor of some kind but I don't know which and googling the label (looks like 25k1904) has gotten me nowhere. The yellow boxes should be inductors with a ferrite core but I don't understand the VK200 labelling. The purple box I'm thinking is a trimming potentiometer? The brown boxes are diodes but not sure if the 12V is referring to a specific type or just that they are connected to the 12V GND. And the green box is a switch ('preklop' translates to 'switch' from Slovenian) but RX izhad and +VRX are throwing me off there.
The pink, red, yellow, and orange boxes look like relays, but I have no idea wha kind. The blue box is a straight up mystery as is the green.
Lastly, was going to use Amazon & a local RadioShack to track down most of the items, but if y'all have any sourcing tips for small electrical components, they are all welcome.
Thanks in advance for any and all help!
