Last time i introduced the Delta M2 Desk Microphone. This post is about the Delta DFC100 wireless frequency counter from the same company.

Although the DFC100 is called a wireless frequency counter it can also be used as a regular wired counter. On the back panel are 4 connecting possibilities.
Two pieces SO-239 connectors for direct connecting to a transceiver and antenna. Next to these is the slot to connect  a 12 Volt DC source.
Last but not least is the connection for the antenna for wireless measurement of the frequency from a transceiver. This antenna is included in the gift box and has a length of approx. 62 cm.

The display reads the frequency in the range from 0.5 – 50 MHz in blue LED’s. On the left hand side is a switch to select wireless measurement on/off. On the right hand side is the general on/off switch.

Manufacturer Delta is based in the USA. In the gift box is a USA 110 Volt AC/DC adaptor. For operation in Europe is is necessary to use a 12 Volt DC adaptor with EU plug. When we used a switching power supply it resulted in a ‘noise’ in the receiver. Maybe this was a one time event.
When using a very cheap KIM KE600 adaptor there was no noise to be heard.

The Delta DFC100 wireless frequency counter is a good counter, easy to use. The extra option for wireless measurement of the transmitted frequency can come in handy.
Do not forget to use a good functioning 12 Volt DC adaptor.

Below is a part of the user manual that shows the specifactions for the Delta DFC100 Wireless Frequency Counter.
