1. [TenTec] Home brew RF power attenuators (score: 1): Author: Ken Brown <ken.d.brown@hawaiiantel.net>; Date: Mon, 31 Dec 2007 17:48:32 -1000; I also built an attenuator from 2 watt carbon composition resistors. My application was a Kenwood TS-440 driving a SGC SG-500 amplifier. The ALC circuitry in the TS-440 made the keying envelope funny; /archives//html/TenTec/2007-12/msg00857.html (10,745 bytes)

Mouser for some and Surplus Sales of Nebraska. Although the latter is a bit pricey but they do have the parts and values often needed. They also have some non-induc; /archives//html/TenTec/2007-12/msg00858.html (12,504 bytes)

They were very easy to make. I just bought some 300W dry dummy loads from Vectronics. Then drilled a hole under the SO239 for BNC connector.

Re: [TenTec] Home brew RF power attenuators (score: 1): Author: "Lyle Dunlap" <qskqrq@grics.net>; Date: Tue, 1 Jan 2008 08:03:20 -0600; A few years ago, in the mid 60's I had an occasion to need some attenuation. I simply turned to a Hallicrafters bulletin (12) pages that gave Attn in Db from .1 in .1 steps to 100 watts. Two tables:; /archives//html/TenTec/2008-01/msg00002.html (8,069 bytes)

Johnson" <geraldj@storm.weather.net>; Date: Tue, 01 Jan 2008 11:18:13 -0600; I have found the 3, 5, and 7 watt metal film resistors perform well at RF and will tolerate a ten times power overload. They may ignite their surroundings when treated that way but that is not enough; /archives//html/TenTec/2008-01/msg00011.html (9,824 bytes)
