If the meter needle vibrates will indicate the working of the circuit and the RF emission. A different approach could be, to connect the oscillator with the Antenna and Ground terminals of a CW receiver that could be tuned with the crystal frequency in order to determine the RF oscillations....
Depending on the 2 meter and 70cm frequencies you choose for tuning your antenna, you might have to compromise a little. I got lucky, because I was using 147.060 MHz and 442.100 MHz, which just happened to both yield a length of 19.08 inches for the longer of the two 3/8″ rod elemen...
There are some antennas available in market but i am not sure if only using the antenna will resolve the issue. Can you please suggest signal booster and any circuit to increase my reception of FM signals? 0 Reply Author Swagatam 3 months ago Reply to Pradosh Hi Pradosh, You can try...

The present invention relates to the fabrication of [Bi4Ti30i2]x - [CaCu3Ti40i2]i-x composite thick film with improved dielectric results making them suitable for use in substrate material as the production of patch antenna. The method includes; synthesize a nanocomposite powder, which can ...
(aka a Noise-Cancelling Passive Loop). If you've been following our previous posts you'll know that we recently started selling the "YouLoop" which is designed and produced by Youssef from Airspy. The YouLoop is a passive loop antenna designed for HF reception, but also works well up ...

That’s it, your wireless speaker box system is ready and may be used for listening to any audio transmission without connecting wires across a radial distance of more than 50 meters, if the antenna is made large enough, the range may be well increased to beyond 90 meters. ...
The loud speaker can be a small 8 ohm 1/2 watt speaker. S1 is a four pole double throw switch with return lever action. S2 is an integral part of a 10K volume control with switch. The antenna is simply a long telescopic antenna (not to exceed 7 feet), which could be a normal car...
The signal received by the second antenna is subsequently provided to a resonance circuit created by L1, L2 and the varicap C2. This allows the meter to be precisely tuned to the specific transmitting frequency which needs to be measured. With the inductance values shown for the coil in the...
