There may be an increased market for an entry-level HF rig that will only cost about as much as a 2m FM rig, because more will now choose to start out on HF. You can, if you want to, stick several hundred bucks into a CB rig. You can also get one for about forty bucks. The latter type will be single mode (AM only) with zero bells and whistles. The former will be AM/USB/LSB and include such extras as some form of RIT, dual power supply (AC/DC), an actual S-meter rather than a bunch of LEDs as a signal strength indicator (if any at all), some basic DSP functions, and reception of NOAA weather channels. The top-of-the-line CB base stations cost far more than a 2m FM rig as it is. But what could be included? Probably SSB/CW only, maybe just a couple of bands (which ones?), probably 10-20 watts out (PA transistors are significant part of the component cost of a rig). Probably only ceramic filters, but maybe with a high first IF a la Alinco (they might be one of the firms interested in this market). Maybe 80/20m to use the image response to make it easier to build, or 40/15m, so the user can just use a 40m dipole? Sounds to me like you just desribed the Ten-Tec Scout with its modules for different bands, except that the price tag does not rival that of a CB rig. Frankly, I don't think we'll see $40 ham HF rigs, ever. Take one of those $40 CB rigs and modify it for use in the AM portion of 10m and see how it performs, and you'll quickly understand why. You get what you pay for. I can, however, see a $200-$300 single-band HF rig (on other than 10m) with limited mode selection and few if any bells and whistles. I exclude 10m from that statement because those have already been offered in the past - see Radio Shack HTX-10 for example. 73 DE John, KC2HMZ Other bands, particularly 15 and 20, have been offered in the past by Belcom, Tokyo HiPower, Mizuho and others. I think more of this kind of thing will surface in the near future. |
