Re: [Flexradio] TXOut Delay.
I've been using my Flex 5000 with a SB-200 and installed Harbach soft-key for several years. Whatever is the default keying delay setting is what I've been using and neither rig has coughed up any hair balls over the past 5 years.

Re: [Flexradio] TXOut Delay.
Seeing as I am using two of these devices in series I am good to go here. I can understand the relay closure and setting issue. My understanding was the Grid voltage dropped when keyed? Or am I thinking of something else? I am trying 50 ms. I am not seeing any real difference in how my rig responds with the increased setting. I may try an even less aggressive setting here.

Re: [Flexradio] TXOut Delay.
Page 9 of the Flex5k manual discusses the keying line limitations and shows an intermediate ckt to be used called the "Protective PTT circuit between TX1-3 and Amplifier". The relay you use "external" to the Flex should handle whatever voltage/current parameters are required by your rig. If you have a -125Vdc line to be keyed, use a relay with contacts rated for that voltage or better. A 30-50ms delay should be fine... 73...Jordan VE6ZT - Original Message - From: "Jim Barber" Cc: Sent: Monday, September 02, 2013 8:18 AM Subject: Re: [Flexradio] TXOut Delay.

Re: [Flexradio] TXOut Delay.
I've been running 5 ms and seemed to have no problems there but am cautious which is the reason for my inquiry. I have a Harbach Electronics Soft-Key installed in the SB 200 and also am using a AmpKeyer in line as it provides a standby mode and I was gifted it. I have noted the 50 ms and am trying that as it seems like an idea that will be gentler on the 572b tubes. On Mon, Sep 2, 2013 at 7:01 AM, Lee Mushel wrote: > Interesting thread.
