Newbie - Selecting handheld dapanattoni on 22/1/20
Greetings Newbie & welcome to Ham Radio!

It would be best to purchase a decent handheld. The cheaper makes and models tend to not comply with FCC spurious/harmonic emission level requirements and can possibly interfere with other radio services. The cheaper models don't hear as well and are more prone to overload and interference. Yes, you do get what you pay for. I am not permitted to give specific advice as to what to purchase.

Importantly, there is much more out there to listen to. A good investment is a software defined receiver. This, and wire antenna, will allow you to hear from 0 to 1 GHz (and more). You will find that AM broadcasting is not all talk shows, but has much to listen for; same goes with shortwave broadcasts. You can also listen to ham AND see their signals on the panadapter of the receiver. This will give you a more rounded view of the radio spectrum and will lead you on a new path of discovery.
Roger beep KI5SGT on 18/12/19
Roger Beeps are not illegal to use. Repeaters use them. There are times when a roger beep is very handy. If a station is mobile and on the fringe of reception, say on 10 meter SSB, the mobile operator's voice may not be heard in the distance, but the roger beep is audible enough to let other station know the mobile station has stopped transmitting.

It is unfortunate that roger beeps are so closely associated with CB radio. The beep is a tool that can be used, especially if the "beeping" signal is weak. However so, a beep to some hams is like hearing "10-4 good buddy"; it's just not "proper ham talk". If you use the beep, be braced for the wrath of the crusty.

As far as the use of phonetics, try to stay on the list of the internationally known phonetics, especially when signals are weak, or if there is interference. There is no FCC rule about using a specified list of phonetics, so have fun, but if you use other phonetics, watch out for the crank who needs a topic to complain about.

Have fun and get on the air.....beep!

Sweep Tub amps and freq. response gordyburdo on 5/11/19
Sounds like normal power output on the higher bands.

100 Watts drive sounds a little high for such an amplifier. If you can, plot the input power versus the output power, on a graph. Start with 10 watts drive and make a power output measurement at 10 Watt increments (of drive). The relationship between the two should be linear (a straight line on the graph). Near the top of the graph, it should curve (amplifier reaches saturation). Use an input power along the straight line of the graph to operate your amplifier in a linear fashion. Operating at, or past the saturation point will increase (transmit) intermodulation distortion, resulting in an abnormally wide signal.
