| Automatic Band Decoder Switch for Low Pass Filters of Extrenal Power Amplifiers | |
| With this switch you will be able to switch automatically the low Pass
Filters of your external Transisto/7Mosfet PA. The advantage to manual band switching of this switch is that always the correct LPF will be selected during transmitting.The PIC device will measure the RF output frequency and select very fast the correct low pass filter. |

| ESD Safe USB Microscope for inspection pcb´s and assembly/soldering of SMD components | |
For the assembly AND SOLDERING of Surface Mount Components and
inspection of printed circuit boards I have modified a high resolution USB microscope! The original stand of the microscope was
replace by a very "thick scrap epoxy materaial plate" of 10 mm and the working
area is 370 mm x 240 mm now. |
