I know this may cause interference problems, but I like to tinker with things. I need a rink a dink am amp for my tx. A non linear would be just fine. I went to the panaxis webpage, but they only had plans for sale. Can anybody tell me where I can get one at, am amps are very hard to find for myself, at least

Hi Travis,

Are you looking for a kit or just for plans?

Travis -- a non-linear r-f amplifier used on a normal AM signal does more than create interference. It also distorts the modulation envelope to the extent that the audio from an AM receiver tuned to that signal can become unintelligible, and even painful to listen to at any reasonable volume.

Experimenting is educational, but probably you shouldn't expect really good results from this particular experiment.

I am looking for a kit. If I could find a ready made one that would be great. Since I'm only trying to test amps is the reason I'm trying to get a regular one. I find linears are virtually impossible to locate.Travis Allred,

Travis,

In order to properly amplify an AM signal, you need a linear amplifier. A linear amp (theoretically) only amplifies the signal, and does not affect the waveform. So, what you put out of the amp should be an amplified copy of what you put in. In practice, this isn't always true.

With very little research, here is what I found. Ramsey Electronics offers an AM amplifier for experimental use only (LPA-1) for $64.90 plus shipping. It is a kit with a maximum rated output of one watt.

If you are using this amp on your Part 15 station, be aware this usage is strictly illegal for station operation over the air. The potential for harmful interference is pretty great. A station would have an increase in signal of 10 db. That's from -10 on a VU meter to 0. That's a lot of increase in signal (about a 120+ percent increase in range, theoretically. If your station goes 1 mile now, your new range would be approx. 2.25 miles). So, be careful and have fun.
