"Jeff Siegel" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Everyone has given me more food for thought. When doing some googling I did find some simple circuits for handling the high voltages so, that's always an option...if needed.
73, Jeff -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Dennis Monticelli Sent: Tuesday, October 23, 2007 12:40 AM To: [EMAIL PROTECTED] Subject: Re: [drakelist] An Introduction & a question about keyer for T-4XB "Dennis Monticelli" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Take heed of the neg vs pos keying that Garey talked about and also the absolute voltage. The old Hallicrafters TO keyer with its mercury wetted relay will key anything, even high current together with high standoff voltage if you install the right RC snubber. The Nye Viking ESK-001 is kind of hard to find but it features both neg and pos (switchable from the rear panel) >300V transistor switches, making it one of the few transistor keyers that can easily handle both cathode keying and grid-block (like the Drakes). I have both a TO and the ESK-001. Be careful of the modern IC keyers on the market. Many of them do not handle neg keying and their max voltage is typically under 50V. You could always build a HV interface circuit if you wished. I did and use it with my low voltage keyers.
