1. Re: [Amps] copper or silver in tank circuit? (score: 1): Author: G3rzp@aol.com; Date: Fri, 17 Jun 2005 03:01:49 EDT; Peter -- It may be a semi-conductor because Cu2O rectifiers were used in battery chargers in the early 1950s. Copper Oxide rectifiers were invented in the USA in the early 1920's. The British Westing; /archives//html/Amps/2005-06/msg00130.html (7,591 bytes)
2. Re: [Amps] copper or silver in tank circuit? (score: 1): Author: G3rzp@aol.com; Date: Thu, 16 Jun 2005 09:17:23 EDT; I think the idea is that silver oxide and silver sulphide are conductors, while copper oxide isn't. So the coil Q stays up after the atmosphere has been at work on it. Wheter or not you can tell the; /archives//html/Amps/2005-06/msg00121.html (7,160 bytes)

Re: [Amps] Gas Regulator Tubes (score: 1): Author: G3rzp@aol.com; Date: Fri, 20 May 2005 18:17:12 -0400; My understanding is that some of the miniature tubes had a radioactive source in them that had alimited half life. This was to ensure starting under dark conditions. So the actual starting voltage mi; /archives//html/Amps/2005-05/msg00220.html (7,089 bytes)

Usual problem is that the air reservoir isn't big enough for continuous tool use. A lot de; /archives//html/Amps/2005-05/msg00108.html (7,277 bytes)

(score: 1): Author: G3rzp@aol.com; Date: Tue, 3 May 2005 09:16:36 EDT; One should also bear in mind that the 'professional' point to point ISB links (such few as are left now!) are typically rated at -36dB on PEP for a 2 tone test, so the results look pretty good to me.; /archives//html/Amps/2005-05/msg00021.html (7,098 bytes)
