1. [Amps] Band switching (score: 1): Author: "hermans" <on4kj@skynet.be>; Date: Sat, 11 Mar 2006 12:20:39 -0000; Hello All, Might be a stupid question...... To avoid using old ledex to swich the tank coil, why one doesn't use relays or PIN diode ? What are approximatively the voltage that can be expected on the; /archives//html/Amps/2006-03/msg00267.html (6,560 bytes)

The voltage rating needs to be at least twice the HV, so we're talking something like 6kV and 20amps f; /archives//html/Amps/2006-03/msg00282.html (7,605 bytes)
