Hi, Mark, Yes, I have observed this. If your frequency is adjusted to be within 10 Hz. of the channel carrier frequency this is supposed to be inaud...
RadioJoe, Paul nailed it with his comments. You have to consider the antenna impedance when optimizing the transmitted power and the impedance of a ...
Classically, the function of a choke coil connected from the antenna output of a transmitter to chassis ground is to prevent an electrical hazard in ...
Can we please get back to the topic of the original post and help and encourage Pat to get on the air. Griping about the power/field strength limits ...
Pat, Don't get hung up about the impedance of the coax. For practical purposes in part 15 (in the US this means license free radio) considering the ...
Regarding the proximity of the two transmitters, please consider operating them on different frequencies. This will eliminate problems of constructiv...
Mark, My comments re AM "fidelity" were directed to the technology and for support I included measurements of my system. There is nothing inherently...
Mark asked "Is the response of 20-17000 HZ the frequency response of the transmitter itself or what you are getting on the air?" The audio response a...
Mark, Very interesting post and thanks for sharing your thoughts and experiences. AM is still my preferred way to reach out, including to my most im...
TheLegacy, Someone who I consider wise once told me "Freedom includes the ability to make an ass of yourself." Perhaps those who broadcast "objectio...
What's going on here? A post questioning the appropriateness (is that a word?) of some alleged Part15 stations' broadcasts has devolved into examples...
Way off topic question and advice for RadioJoe. Did you ever solve your hum problem with your KnightKit broadcaster? I did so for mine. The problem...
Thank you very much for report on your testing of various FM "car" transmitters. Sorry, but I think it is not workable to promote range beyond a few ...
Thanks for the report and glad you had the chance to meet Bill Baker. I look forward to the day (not going to happen?) when the rest of us can run a ...
