1. [TenTec] Wall transformers (score: 1): Author: jkbelt@spiritone.com (Jim and Kate Belt); Date: Fri, 17 Jul 1998 08:44:33 -0700; Hi All: Recently I put a Logikey K3 keyer into operation. The manual says not to use wall type transformers since anything over 14 volts DC is apt to fry the unit. I had planned on using the MFJ 1313; /archives//html/TenTec/1998-07/msg00171.html (7,482 bytes)
2. [TenTec] Wall transformers (score: 1): Author: geraldj@ames.net (Dr. Gerald N. Johnson, P.E.); Date: Fri, 17 Jul 1998 10:01:02 -0500; Some wall warts are regulated, most are not. The CMOS loads of the keyer would let that 18 volt one ride at 18 volts and very likely fry to keyer. 73, Jerry, K0CQ -- FAQ on WWW: http://www.contesting; /archives//html/TenTec/1998-07/msg00172.html (6,962 bytes)
3. [TenTec] Wall transformers (score: 1): Author: rrossi@btv.ibm.com (Ronald D Rossi); Date: Fri, 17 Jul 1998 12:32:11 -0400; The key is (usually) looking at the wording on the wall-wart. If it says 12VDC at 200mA it is likely unregulated. Checking it open circuit as you did is a definite giveaway. -- 73 de KK1L...ron (rro; /archives//html/TenTec/1998-07/msg00173.html (8,007 bytes)
