DIY: Easy 2m Dipole Antenna | Dipole antenna, Ham radio

As for ham radio, the FCC has allocated a specific set of frequencies that start at the AM radio band at 1.6 MHz and end at 1240 MHz. This range includes two radio frequency bands, Very High Frequency (VHF), and Ultra HIgh Frequency (UHF), each of which has its pros and cons This 5-watt speaker can be turned into your own DIY ham radio speaker in comparison to factory radio speakers. It performs way better while offering louder and clearer sound quality. Best of all, it comes with minimal background noise, making it more comfortable for use at night

Made by RCA, the speaker is under model number PROX33AV, Radio Shack catalog number 40-5000. This eight ohm speaker is designed for 15 watts RMS, 30 watt peak audio and is more then ample for Amateur transceiver duty. The speaker has full rich sound and brings to life SSB and CW audio. I was amazed that an inexpensive book shelf speaker could. Among all the ham radio projects that I have waiting on my drawing board, I find that this one fits the goal in the preceding paragraph perfectly. The Project's Purpose. I needed to protect the sensitive front end of my QS1R SDR receiver when transmitting with my IC-7200 barefoot Rather, it is the voltage drop through the radio—as much as 2 volts in some cases. This can cause some powered speakers to operate erratically. ☜Return☜ Non-DSP Powered Speakers. The audio output in modern transceivers seldom tops 3 watts, which is barely adequate especially in a noisy mobile environment After checking the cross-over network, these 2 speakers are cut off below 70Hz but only up to 3,500Hz. This is the average range that any good ham radio can produce. The tweeter is a 2 1/2 inch monopole ribbon tweeter. It's cross-over allows only the range between 2,600Hz and 25,000Hz to pass to the tweeter, and frequencies above 15,000Hz.

What attracts a lot of people to amateur radio is that it gives you the ability to make your own gear. Scratch-building hams usually start by. You can make your own simple AM radio antenna using a piece of wire. Use a small diameter insulated wire, such as a 20 or 22-gauge, and cut it to a length of at least 15 or 20 feet (4.6 or 6.1 m). To boost the reception, coil the wire in a circle and use zip ties or electrical tape to keep the coil from unraveling 468 divided by 5.90 = 79' 3. The number 468 divided by the frequency above is the formula for calculating a half wave antenna length used all the time by Amateur radio operators in building many different kinds of antennas. You'll need about 435 feet of wire for this antenna plus appropriate length of coaxial cable
