2. Re: [Amps] triode or tetrode (score: 1): Author: Jim Hoge <knowkode@verizon.net>; Date: Thu, 26 Aug 2010 20:45:35 -0700 (PDT); I haven't made up my mind as to buy or build. If I build, I know it will take me too long to complete the project and I will have a tendency to upgrade components above and beyond what would be adequ; /archives//html/Amps/2010-08/msg00397.html (8,252 bytes)

Re: [Amps] Ebay selling CB amps (score: 1): Author: Jim Hoge <knowkode@verizon.net>; Date: Fri, 18 Feb 2011 09:55:13 -0800 (PST); I would think so and because they charge listing fees, they are effectively a virtual consignment store. BTW, craigslist does too, against their policy. Jim W5QM _____________________________________; /archives//html/Amps/2011-02/msg00137.html (7,674 bytes)

Part of the problem is licensing. To get the material, one must be a certified installer. It's a cl; /archives//html/Amps/2012-03/msg00227.html (8,276 bytes)

A spherical radiator is a true isotropic radiator until it is affected by its relationship to ground, other structures, the mast upon which it sits, and its feedline.

Re: [Amps] Silicone hose from Flex Technologies (score: 1): Author: Jim Hoge <knowkode@verizon.net>; Date: Fri, 20 Jul 2012 10:43:53 -0700 (PDT); The purpose of a chimney is not to absorb RF radiation but to direct airflow. The only specification that really matters is whether or not it will survive the ambient temperature of its environment.; /archives//html/Amps/2012-07/msg00230.html (8,310 bytes)
8. Re: [Amps] Silicone hose from Flex Technologies (score: 1): Author: Jim Hoge <knowkode@verizon.net>; Date: Fri, 20 Jul 2012 14:08:38 -0700 (PDT); Point taken. With the exception of a chimney pulling double duty as an anode resonator such as in K5GW's 432 amp, the chimney material shouldn't be conductive or rf absorbant. _______________________; /archives//html/Amps/2012-07/msg00233.html (10,303 bytes)

I've heard the claims from some who run stock that they are capable of such numbers. I had a boss who was an ardent cber ask me to fix his mobile solid state amp.
