[CQ-Contest] Testing Stubs (score: 1): Author: ludal@dmv.com (Dallas Carter); Date: Fri Aug 1 18:03:55 2003; Mike, It's virtually impossible to evaluate your problem from the description of your hookup. It is very possible that you are suffering from common mode RFI. I would do some experimenting with the g; /archives//html/CQ-Contest/2003-08/msg00067.html (10,145 bytes)

5. [CQ-Contest] Testing Stubs (score: 1): Author: k4sb@earthlink.net (K4SB); Date: Sun Aug 3 15:56:35 2003; Trick I use is to put on 1 pl259, and then measure the stub with the 259 at a very high harmonic of the frequency I want. For example, 20th harmonic of 7.0 is 144 mHz. You will find the dip extremely; /archives//html/CQ-Contest/2003-08/msg00078.html (8,125 bytes)

[CQ-Contest] Testing Stubs (score: 1): Author: k6ll@juno.com (Dave Hachadorian); Date: Mon Aug 4 11:02:04 2003; Peter, The paint cans look like a great idea, but I am trying to understand the pictures. Why are there two coax connectors on the can, rather than one? Is it just to eliminate a coax tee? It looks l; /archives//html/CQ-Contest/2003-08/msg00089.html (8,373 bytes)
