Welcome to Reddit's own amateur (ham) radio club. If you are wondering what Amateur Radio is about, it's basically a two way radio service where licensed operators throughout the world experiment and communicate with each other on frequencies reserved for license holders. Enter VFO mode on the radio. The manual explains how. Select a frequency that is valid for GMRS use. Press PTT. The Wouxun Part 95 radios sold by BTWR with VFO modes have special firmware that has the FCC limits baked into it. The firmware knows the GMRS frequencies, the power limits, the offset and bandwidth limits. 3-30MHz Low Distortion Sinewave Signal Generator. The Si5351A Synth in the VFO/SigGen kit produces a squarewave output. Starting in firmware version s1.03 the processor can control the 6 relays in the 6-band Relay-switched LPF kit.This feature can be used to automatically select a LPF depending on the VFO operating frequency, to optimally remove .
You do not have to remove the VFO. Make sure rig OFF and UNPLUGGED. Remove top cover..be careful of the speaker wire. You can either leave in place or remove the bottom cover. The VFO enclosure is obvious. Stand rig in the service position. You will see a small rectangle "door" on what is now the top of the VFO. You only have
Metal enclosures and cabinets for housing electronics, gas supply or plumbing come in many shapes and sizes. Each has either a specific use case, or a variety of applications.
