Along with the 5W PA kit, I also ordered a new MCU for my U3S with the latest firmware, as this supports the external switching functions I intend to use to add an antenna changeover relay to give an ongoing antenna feed out to a receiver - in my case an FRG-100.
But enough! You dont want to hear me chatting about this, so, here are the pictures of the build so far...
|The bagged kit. Good strong bags!|
|Capacitors fitted. The quality of the PCB can be seen here|
|Fitting the resistors. This kit is rather resistor heavy!|
|All the 1/8w resistors fitted except one (a later mod)|
|The 2W 0.33r resistor and the preset installed|
|5V regulator and IC socket now fitted|
Before I get too far into the semiconductors, I really should finish the rewire of the mains distribution for the bench! The 4-way socket is being replaced with a 6-way. And the earth pins on the ESD plugs, which is what has damaged the safety shutters on the 4-way panel, are going to have a bevel filed into them! At least the workshop lighting has now been replaced with the new LED strips. If only now I could get used to the new location of the light switches!
