1. [CQ-Contest] Help for pull-up resistors (score: 1): Author: PaulKB8N@aol.com; Date: Tue, 4 Mar 2008 14:39:46 EST; Sorry, this is a bit off topic, but I can't find anything in the K-3 archives on this. I've have a new K3 coming in tomorrow and want to do antenna switching via the band-data outputs. I've purchased; /archives//html/CQ-Contest/2008-03/msg00089.html (7,526 bytes)

Re: [CQ-Contest] Help for pull-up resistors (score: 1): Author: "Dick Dievendorff" <dieven@comcast.net>; Date: Tue, 4 Mar 2008 19:49:45 -0800; One end of each of four resistors goes to the four band data lines (output from the K3 DE-15 accessory jack, input to the W9XT card). The other end of each of the resistors goes to +12V. They "pull"; /archives//html/CQ-Contest/2008-03/msg00107.html (9,156 bytes)

Tie one end of all four together to the terminal +12VDC. At the other end of the resistors, one of each goes to input terminals ABCD, tied to the wires coming from the K3; /archives//html/CQ-Contest/2008-03/msg00110.html (8,255 bytes)

Re: [CQ-Contest] Help for pull-up resistors (score: 1): Author: "Dick Dievendorff" <dieven@comcast.net>; Date: Tue, 4 Mar 2008 21:16:34 -0800; Maybe it should be pulled up to +5V, I'm not sure it matters that much. The W9XT BCD-10 schematic shows logic levels of 0 and 5V. The Elecraft K3 Owner's manual (on the Elecraft web site) says that t; /archives//html/CQ-Contest/2008-03/msg00111.html (10,488 bytes)

I like this statement from Hollywood land :-) Radio PTT is often pulled to +14V, data lines mainly to +5V TTL level. 73 de Mario, S56A,; /archives//html/CQ-Contest/2008-03/msg00117.html (7,553 bytes)
