Next weekend the VHF UHF SHF contest season is starting.
Before we can start I have to do some repairing and preparation.
Today I went to Jaap PA0T. One of my 1144 MHz preamps with a smd hempt fet in is broke. These smd fets are too small for me and Jaap would like to help. We were lucky. It was not the fet that was caused the problem but a loose contact. We also looked to one of the driver pa’s. It would not switch. It was repaired before and a switch transistor made bad contact. This was a easy repair but hard to find.
