Modification of PLJ 1601 C Frequency Meter, installing TCXO JYEC 13Mhz
In this video we modify an inexpensive Chinese frequency meter PLJ-1601, install TXCO JYEC 13 Mhz. As a result, we got a fairly accurate device for little money. A new reference generator was installed instead of the original, no additional components were needed. The final accuracy in the range of 0.1-60 MHz was +-1 Hz, 60-1200 MHz accuracy +-64 Hz.
