Why are rigs so small? I think it's Art Collins' fault. And card tables. Look at typical ham gear of the mid-to-late 1950s, and you'll see receivers and 100-watt-class transmitters that took up most of the top of a standard office desk, and whose combined weight ran 150-200 pounds. For example, the classic Heathkit Mohawk/Apache pair took up a space about 40 inches wide, almost a foot high and over a foot deep. And you better have a substantial operating desk to hold them, because of the weight.
Then in 1959 came the revolutionary KWM-2. While not the first manufactured amateur SSB transceiver, nor even the first 80-10 meter one, it was revolutionary. A complete 100 watt SSB station in a box smaller than most receivers of the day. Sure it needed an external power supply, but that could be tucked away out of sight since it had no operating controls and was very small and light. Such a rig could be tucked away in a small space, or even set up on a card table with straining it. Fast forward less than a decade, and many rigmakers were making their version of the KWM-2. Heathkit had the SB-100/101/102 series, which were about the same size as the KWM-2 and followed the same basic design ideas. Yet an SB-101 with power supply, speaker and CW filter cost less than the Apache/Mohawk combo. For high power, add the Heath SB-200 amp - $200 and the same size as the SB-101. This reduction in size, weight and cost is why SSB replaced AM and why transceivers replaced separates for most hams. Hamshacks could move out of the basement and into the living space, and high power (particularly on 'phone) no longer meant a six foot rack or two and a second mortgage. For many hams it meant the ability to have a much better station than they had thought possible, due to space and cost limits. It all started with the KWM-2 73 de Jim, N2EY ************************************** Get a sneak peek of the all-new AOL at http://discover.aol.com/memed/aolcom30tour _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
