There are better circuits though, which are crystal-locked so that they don't drift. However, AM transmitters require very good grounding, and long wires, but to comply with IC RSS-210, I cannot use long wires or have extensive grounding systems. For example, 10 feet of wire with my signal on 1700kHz only covers around Rolly View Rd / TWP 494 (east of Leduc) but the FM TX on 107.3MHz covers up to Leduc Common on a good day at 33 feet and full 0.01W power out (not ERP. Again, to comply with RSS-210 - that's exciter-only. With the power amp turned on, it can go up to 50W TPO) - and grounding isn't AS important, just HAAT. Which is why FM is better suited to flea-power projects.
I dream that one day the CRTC will finally respond to my letters, but I have mostly given up on the hope of having them pay attention to my attempt at a low-power community station. So I'll stay within the RSS regulations and everything will be fine. Well, unless they approve one of those new Edmonton stations in the same frequency region.
I find that it is much easier to get a license for non-broadcast frequencies. That way, you only have to deal with the technical side of things, whereas with broadcast, you have to deal with technical and the social-political side of things.
And once again, I am rambling and going off on odd tangents. |
