IOW, it would add too much to the cost of a rig. STANDARDIZATION, nearly all of it industry standards, make up nearly everything in the component parts of any manufactured and nearly every home-built radio equipment for at least the last half century. Everything from fasteners (nuts and bolts) made to English and metric industry standards, vacuum tubes, resistors, capacitors, inductors, transistors and diodes (of the 'registered' 2N and 1N prefixes). The standardization being discussed was about things like power connectors and the possible feature of the rig not transmitting outside the licensee's privileges (such as no 'phone in the CW/data subbands). btw, many of the parts in consumer and amateur electronics today are "house numbered", particularly ICs, and replacements can be a real problem. 2) The rigmakers don't want any more interoperability, because it means less sales Aeronautical Radio, Inc (ARINC) was once solely a commercial company engaged in providing air-ground communications with aircraft before our government got its act together and created the air traffic control system. They still do that but ARINC is better known to commercial avionics equipment makers as an industry Standards Group that, by common agreement of members, establishes standards on all civilian avionics equipment. Key factor there is "common agreement of members". 'S Meter' levels aren't really standardized as to receiver input signal levels except as a 'common use' standard and a recommendation by the IARU. Even if S meter readings were standardized, differences in antenna systems would make the readings meaningless on an absolute scale. Yet most are under the impression that all S Meters are calibrated/scaled alike (they aren't) and routinely report their S Meter readings in QSOs. :-) Who are "most", Len? None of my homebrew receivers or transceivers has ever had an S meter. Yet I give signal reports as part of most QSOs. Amateur radio equipment, especially transceivers, are designed and made for stand-alone use. Most are, but not all. For example, the Kachina 505DSP, introduced about a decade ago, requires connection to a computer. Same for the Ten Tec Pegasus, introduced about a year after the 505DSP. The inexpensive PSK31 transceivers commonly known as the "Warbler" is another example. More recently, some software-defined rigs have been produced that require computer connection to operate. Peripherals are relegated to outside-the-antenna- connector devices or different speaker boxes and other audio processing things. Isn't being "outside" the definition of "peripheral"? Many rigs nowadays have numerous *internal* options as well, such as filters and firmware upgrades. These are almost always manufacturer-specific if not model-specific. At least one company (Elecraft) makes their transceivers available with a wide variety of internal options that can be added at initial construction, or later. For example, their basic K2 transceiver is a 10 watt CW-only 80/40/30/20/17/15/12/10 rig. Options include an antenna tuning unit, SLA battery, analog and DSP audio filters, SSB, 160 meters/second receiver antenna input, noise blanker, 60 meters, 100 watt amplifier, and serial port. Their other products offer similar options. But they are all specific to the manufacturer. www.elecraft.com The external connections are standardized as to power input (AC standards from the power distribution infrastructure or DC power from the auto industry), Not on amateur gear. Some use Molex, some use PowerPoles, some use other connectors for DC power. computer interface connections (USB, serial, parallel) if those are included for read-out or computer control, and 'open-source' connections such as automatic antenna tuners made by the originating manufacturer or by independent suppliers. Microphone, headset/speaker, morse key connections still aren't standardized fully, not even as de facto standards; that allows more sales of adapters for that small niche market. :-) My point exactly. I'm puzzled about all this palaver over some bandplan automatic lock-out on frequency control and transmitting. What's the puzzlement? It's just a proposed feature. Allocations of amateur frequency and modes for same aren't locked to any standard but the common-agreement terms of the ITU-R. Sub-band allocations are always at the discretion of the national radio regulating authorities and may change at any time dependent on that nation's politicking for sub-band use. :-) The idea was that the rig could prevent an amateur from accidentally transmitting where s/he wasn't supposed to. Not just out-of-band but out of subband, even when the handy frequency chart isn't available, or the operator doesn't look at it. 73 de Jim, N2EY |
