AVT2831 UK

The system is used to measure the frequency in the 4-160MHz range. It can be used as a radio frequency meter or as a scale for a TRX transceiver device, e.g. 144MHz (2m). The system allows programming any offset (subtracting or adding) of the frequency measured by the intermediate frequency or another value determined during programming of the processor. It is not possible to set this frequency during operation of the meter, therefore a programmer for AVRs and BASCOM-AVR is required for correct programming of the processor.

The device is particularly useful for amateur radio players and radio amateurs

Selected parameters:

• measurement in the range of 4-150MHz
