[Flexradio] Flex-5000A TX1, TX2, TX3
Tim . can you please confirm if this is correct??? Looking for some further explanation of TX1, TX2, TX3. The manual could still use a little help or a good example. I want to use TX1 and TX2 as a sequencer. I want TX1 to control transmit/receive relays, TX2 to control 8877 amp. I think: TX1 delay 250 TX2 delay 150 Will cause: TX1 to switch 250ms before the Flex actually transmits TX2 to switch 150ms before the Flex actually transmits Resulting in: T/R relay to switch, followed by amp to key 100mS later, followed by Flex to transmit another 150mS later. Is this correct (or backwards)? 73 Kevin ___ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
Re: [Flexradio] Flex-5000A TX1, TX2, TX3
That isn't how the TX relays operate. it isn't a sequencer. When you press (assert) PTT, the TX relays close immediately. If there is a time delay value set, then RF is not transmitted until the delay time period expires. Example: TX Relay-1 is connected to an AMP and it has a TX time delay of 100 ms. ANT-1 is connected to the amp I press PTT The amps keys immediately No RF is allowed to egress the ANT-1 until 100 ms pass after pressing PTT. I hope that clarifies how it works, but I suspect that is not how you had intended it to operate. -Tim --- Tim Ellison, W4TME Product Management, Sales Support FlexRadio Systems^(TM) 4616 W Howard Ln Ste 1-150 Austin, TX 78728 Phone: 512-535-4713 Ext. 223 Email: t...@flexradio.com mailto:t...@flexradio.com Web: www.flexradio.com http://www.flexradio.com logo /Tune In Excitement^(TM) PowerSDR^(TM) is a trademark of FlexRadio Systems/ On 9/6/2011 4:50 PM, Kevin Hobbs wrote: Tim . can you please confirm if this is correct???

Re: [Flexradio] Flex-5000A TX1, TX2, TX3
TX1/TX2/TX3 do work as a sequencer (see Eric Wachsmann's 5/31/2011 reply to the FlexEdge reflector titled TX1 -2-3 info?). Tim's example is correct for a single TX line connected to an amp. However, TX1/TX2/TX3 are sequenced when using multiple TX lines with delays. In other words, TX1, TX2 and TX3 do not all turn on (connect to ground) simultaneously. Here's how the sequencing works when TX1, TX2 and TX3 are all selected for a given band: Push PTT 1. Flex 5000A switches to transmit, but no RF out 2. TX1 On (no delay) 3. Wait TX1 Delay 4. TX2 On 5. Wait TX2 Delay 6. TX3 On 7. Wait TX3 Delay 8. Flex 5000A RF Out Starts Release PTT 1. Flex 5000A RF Out Stops 2. Wait TX3 Delay 3. TX3 Off 4. Wait TX2 Delay 5. TX2 Off 6. Wait TX1 Delay 7. TX1 Off 8. Flex 5000A switches to RX **TXn On indicates that TX port n is connected to ground causing the relay to close; TXn Off indicates that TX port n is open (not connected to ground) causing that relay to open. This is exactly how you want a sequencer to behave. This also works if only pairs TX1/TX2, TX1/TX3 or TX2/TX3 are selected. Just skip the appropriate steps above involving the unused TX port and its delay. 73, Clay W7CE On 9/6/2011 2:28 PM, Tim Ellison, W4TME wrote: That isn't how the TX relays operate. it isn't a sequencer.

Re: [Flexradio] Flex-5000A TX1, TX2, TX3
And, every time restart PowerSDR it seems to untick my TX3 setting for 6m and leaves only TX1 ticked? Does it not like using 2 TX ports on 1 band? -Original Message- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of Kevin Hobbs Sent: September-04-11 1:11 PM To: flexradio@flex-radio.biz Subject: [Flexradio] Flex-5000A TX1, TX2, TX3 Hi Looking for some further explanation of TX1, TX2, TX3.
