Saw this project today, ordered the pcb's straight away! Sourcing the components right now but I'm having some questions regarding some components, especially because there often are multiple versions. I have found an old basestation in our shop collecting dust, a tecpro MS721, from what I understand this basestation is working with the beltpacks right? So that is the thing where I'm collecting parts for. Here are my questions: What is a good substitute for Farnell – 2309743, since it is no longer in stock?Can the testpoint (TP1) be done in another way? 15 euro's for 1 testpoint (I need to buy 100) is a bit much...The TL072,NE5534, J175, BC547 and MPSA14G don't really list the letters/numbers after the part, so does it mather which version to get?I picked, in this order, the TL072CP, NE5534AP, J175-D26Z, BC547B, MPSA14 (farnell 1574389) I scored a nice deal on the prints on JLC PCB, and I might have some left in the Netherlands once I'm done, I'm willing to sell those if anyone is interested!
