In a VHF (Very High Frequency) diagram, two mixers are typically used for frequency conversion to improve performance and selectivity. The first mixer down-converts the incoming VHF signal to an intermediate frequency (IF), allowing for better filtering and amplification. The second mixer can be utilized for further processing or to shift the signal to a different frequency band. This dual-mixer setup enhances the overall system's sensitivity and dynamic range, enabling more effective signal processing in communication systems.

VHF is in the range 30 to 300 MHz.
VHF radios work by the line of sight principle

One can purchase VHF two way radios from many places. Examples of such places are Dino Direct, Pirates Cave, DH Gate, Merit Line, and Digital 2 Way Radios.
Eleven TV channels are in the VHF spectrum. My count is 12 in the USA (2 -13).
You need a VHF radio antenna, a VHF radio receiver and of course a station broadcasting on the VHF frequency.

To connect 2 mixers together for seamless audio mixing, use a stereo cable to connect the main output of the first mixer to an input channel on the second mixer. Adjust the levels on both mixers to ensure a balanced sound.
Digital TV signals are transmitted on VHF starting on channel 2 and ending at the top of the UHF spectrum channel 69. At one time the plan was not to use the VHF band but it didn't work out that way.
The VHF channels go from 2 to 13, so there are 12 of them. So, 19 + 12 = 31.
The speaker in Concrete Mixers thinks they are interesting and impressive.
You need a VHF/UHF antenna (channels 2 to 60 ). Check out: http://www.fcc.gov/cgb/consumerfacts/digitaltv.html
A VHF ocsillator is a very high frequency ocsillator (30-300MHz). It oscillates (swings back and forth) at a VHF frequency.
VHF is in the range 30 to 300 MHz.
CQ VHF Magazine was created in 1996.
