Alex VE2AMT and Jacques VE2EMM. |
||||||
Jacques makes a first test with the oscilloscope. |
||||||
All problems must be found. | ||||||
This homemade device is useful to check if the Doppler reads all the 8 antennas. | ||||||
A paper is stuck on each Doppler on the test bench. | ||||||
It is necessary to measure the voltage of each antenna separately. | ||||||
|
||||||
Checking the Max 204 in the switcher. | ||||||
|
||||||
The final test. |
||||||
We have to test the voltage of all four antennas. | ||||||
We use a VOM meter on each antenna. | ||||||
This antenna is not reading. | ||||||
The voltage is 4.45 volts when an antenna is reading. | ||||||
