Re: [Flexradio] TXOut Delay.
Interesting thread. I suspect that the topic is simpler than people might want it to be. When I started to use the Flex3000 with a rather heavily used SB200 some three years ago I wondered about the possibility of mixing tube and solid-state voltages and was told to not worry about it. But being a conservative person I bought a Sunlight isolation relay box (no longer available), never adjusted anything and have never had any problems. But then I've long felt that people tend to be overly cautious which can lead to wanting to be taken care of. 73 Lee K9WRU - Original Message - From: Jim Barber audio...@q.com Cc: flexradio@flex-radio.biz Sent: Sunday, September 01, 2013 10:14 PM Subject: Re: [Flexradio] TXOut Delay. 50ms is probably around the minimum for an SB-200.

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.

Re: [Flexradio] TXOut Delay.
If you don't care about arcing the relay contacts or generating a burst of nasty, broad signal when you key up, then of course you'd be right. If your transceiver could handle the switch voltage/current/inductive spike of the amplifier relay key line, you'd be right again. In your case, though, since the SB-200 uses a 120V relay coil, I somehow doubt the F3K's switching transistor would tolerate that for long without the isolation box. Perhaps someone from Flex knows the actual spec. Not sure how overly cautious applies here? 73, Jim N7CXI On 9/2/2013 7:01 AM, Lee Mushel wrote: Interesting thread.

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 audio...@q.com Cc: flexradio@flex-radio.biz Sent: Monday, September 02, 2013 8:18 AM Subject: Re: [Flexradio] TXOut Delay.

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.
