Electronics Two Way Radio

I'm not familiar with this particular product, but, since the latest bunch of Chinese made crap has over a 70% return because of not working, I would be suspect of any electronic devise made in China.
I speak of these no good digital TV converter boxes.

Kenwood#39;s ProTalk PMR446 hand-held radios are rugged enough for use day after day and simple enough for non-technical workers to use like any ...

I am in the process of launching a new electronics brand. The products will be two way radios and accessories. I am stuck right now coming up with a name, and would appreciate suggestions. Thanks!

Sparks communications can use lightning bolts on both sides. Or "Ham it up" if you are selling ham radios stuff. "Both ways communication" "Open Channel" "Chirp Me " Good Luck

Price: $69.99

Bundle includes pair of radios with belt clips, headsets, desk charger, and battery packs/adapter
Features include five animal call alerts, roger beep, channel scan, vibrate alert, monitor and more
NOAA weather alert radio with scan for severe weather and other emergency alerts
42-channel GMRS radio with up to 36 mile range and 142 privacy codes
eVox with three sensitivity levels for hands-free, voice-activated transmission

How is it doing that ?
It only does it when my guitar has volume in it.
I use two amps (preamp and a cabinet)
I have a lot of electronics in my room (Tv, FM Radio, Computer, amps, cellphone, etc...)
It's really weird.

Its like when a computer picks up waves exerted by a cell phone, so the computer will have random lines run through. The radio wvaes are traveling through the air and more than likely the amps absorb them.

I have two radios (cd/tape/radio) that my puppy decided to chew the power supply cords to. I don't know how to repair them nor do I need them laying aroung my house while I try to get them repaired...so is there somewhere I could take them where they would be recycled or fixed and given to someone who needs it?

Absolutely! Check with your city. They may have a recycling center that accepts electronic devices. Look in the telephone book under recycling. I found a place within a mile of where I live in the telephone book. I didn't use the city facility because it is about 15 miles away.

The PA amp's brand is Grommes Precision Electronics, model PST60. Its output is a single 60 watts RMS. Two homemade "PA speakers", with full-range 15-inch drivers that seem to have been made for guitar amplification (specs unknown but they look at least 30 years old), are connected in parallel to the amp. These speakers sound lousy while projecting voice (though they sound okay projecting acoustic guitar music, which makes me think they are guitar amp drivers), so I'm thinking of getting a smaller pair of actual modern PA speakers.
The impedance load for the PA amp is rated at 4 - 8 ohms (I imagine using two speakers wired in parallel vs. using one speaker, correct?). If I bought two PA speakers whose impedance are 8 ohms, would the in-parallel 4 ohm load be okay? This drop in impedance would cause the wattage of the amp to increase by how much?
I'm considering two Radio Shack 10" PA cabs, with an RMS rating of 75 watts/160 watts peak.

Thanks in advance for any help!

Lowering the impedance to half will increase the output by 3 dB. (this comes at the cost of a little more distortion).

Also keep in mind that not all speakers are created equal, as some are more efficient than others, so if you are replacing a single more efficient driver with two less efficient ones, you may not notice any difference, other than some added distortion. If the cabinets are smaller, its probable they are less efficient. (Most speakers have an efficiency rating i.e. 88dB, so you can use that for comparison).

Buy from some place with a liberal return policy, and try it out. You can always bring them back if you don't like the sound.
