A friend brought a Kenwood IF-232C Serial Port Interface to me a while back asking for a little assistance with repairing it. He had replaced multiple components in it but it still wasn’t working properly. When hooked up to a Kenwood TS-850 radio and a computer, the computer could not communicate with the radio or […]

Testing the New IFR 1500 Inverter Board Before Installing the FET’s
Update to IFR Inverter Board Recreation Project
The project of building in Inverter Board for the IFR FM/AM-1500 Service Monitor from scratch is moving along pretty nicely. At the moment, I’m simply waiting for a supply of IRF521 FET’s to arrive, at which point I’ll just have to add two of them to this board, reinstall the board, and test the machine. […]

I tried to patch it up and replace the burned out FET, but the board is pretty much a “goner.” The power supply is still getting “bogged down” with this board in place, and […]
Now Designing and Building PCB’s In-House
2018 is off to a decent start already, considering that I’ve already accomplished my first personal goal of gathering the “stuff” and setting up to design and build printed circuit boards (PCB’s) in-house. Quite handy for turning designs into actual prototypes and working PCB’s without having to send off the design for someone else to […]
