Re: if you go with export you can have a howl lot of fun
::sigh:: We have met with several occasions with Jim Peng, JR, and several others from RCI, and several other engineers from RCI in National City, CA. in fact, we have several photos with us in them to prove it. Almost all, in fact I can't think of one off the top of my head that doesn't have a filter for 54Mhz. I keep seeing a rant and rave from this guy about harmonics. Harmonics are only one small part of the equasion. Yes, radios generate harmonics...can we please move on? Every transmitter of any type of amplifier AC, DC, AF, RF generate harmonics!!!!! If you actually take the time to run a spectral purity test, you'll see that most of the radios that you are talking about are still down by at least -35db. NOT BAD CONCIDERING that most HF amateur radio amplifiers with a PI or PI-L network are down by about -35, to -38db or so. Check out Ameritron's website, and check out their specs. Yes alot of Cb'ers do operate things incorrectly, that's why it's CB, anyone can connect a radio and amplifier and go with no concept or a very brainwashed theory of how RF circuitry actually works, get a wattmeter and see a zillion watts out of a IMD splatter box. If you're going to sit here and post after post after post talk about connecting low pass filters to mbile amplifiers, and how a radio is generating harmonics, at least provide facts and documentation to back up what you are stating. I welcome everyone's input, but when it's down-right a statement, such as the sky is purple, without any significant documentation, or research, it gets rediculous. Once again, I agree, a export radio with a disabled AMC isn't the cleanest radio in the world, in fact far from it. Keep in mind, many AM transmitters don't have an AMC circuit by design.
Instead of going on and on and on about harmonics, why not discuss something like an export radio's wide receiver bandpass, or extremely high gain in the front end, and IF filtering that is way too wide? How about some solutions? We already know that a good ol' truckdriver special galaxy doesn't compare to a Harris, or an Icom 7800, Yaesu Ft-1000D, etc, but we're comparing oranges and apples here.
Some things about exports that I don't like is the horrible quality control, and horrid receivers. I have talked with RCI, who by the way makes and manufactures galaxy, ranger, connex, mirage, virage, and many others, and offered suggestons for these problems. They will do nothing. So I come up with creative ways to correct some issues, like a gasfet for the front end, lowering the gain in the 1st RF amp, narrowing up the IF stage and increasing gain there.
My point is, let's keep it postive on the forum, please. <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/roll.gif ALT=":rollin">
