6500, transverter and AR2 Preamp
Fast forward to today, I sold the Icom-9100 to finance my flex-6300 trade up to a flex-6500. I still have the antennas and the preamps. I have also added two transverters, both Elecraft, one VX432 and a VX144 and have them built, aligned and tested. So now I’m trying to figure out how to go about getting power to the preamps and removing power when transmitting and utilizing my 6500 for SAT work.
I have two options I think…
1) power the amps through the coax again.
2) power them via external connector.
I’m leaning the external connector but do not know how to handle the power off when transmitting, I’m assuming a sequencer, but what one? How do they work? What connections to the radio do I need? Does the sequencer provide power to the preamps?
Looking for some guidance, instruction, information on the subject and if anyone has done this how did you handle the situation?
Thanks
David

Hi David, there are a few options out there to handle what you are trying to do. Take a look here: http://www.w6pql.com/amplifier_control_board.htm and Here: http://www.w6pql.com/lna_sequencing_and_protection.htm.

SSB makes excellent mast mounted preamps that are both RF sensing and have a control line for putting them in bypass mode when transmitting.0

Advice.. not sure this is the place but here goes... I have a M2 Sequencer model S3, I have a AR2 Preamp model MSP432VDG-160, I also have a Elecraft XV432 transverter..
Trying to determine the wiring for this setup. I'm think this is correct but would like someone to verify it for me..
S3 - (I do not know what the jumpers should be set to)
Pin 1 = +12V
Pin 2 = Key line outside??
Pin 3 = Ground for 12V
Pin 4 = to terminal B on connector of AR2 preamp (provides ground to AR2)
Pin 5 = to terminal A on AR2 (provides +12V)
Pin 6 =
Pin 7 = Center key??
Pin 8 =
Pin 9 =
Where I'm confused the most is I assume there is a key line to be used.. right now there is a key line from the 6500 to the transverter, so from the transverter there would be a key line there to the S3 sequencer.. but there is a shield and a center connector.. which goes which... outside shield = ground? and center is control?
Second part of my question would be what jumper settings to set in the S3 Sequencer? Does the FLEX provide Ground to TX?
