Does Flex hardware tally when SSDR has connected?
Im integrating our second remote Flex transceiver at the Tampa ARC. This one is a 6500. In our 6400 system, we have the rig connected to essentially monobanders through an external antenna switch controlled by Green Heron Everyware. Users there manually switch antennas and when they are finished, they ground all antennas via the antenna switch, disconnecting them from the radio.
On this second transceiver, the antenna will be a tribander and a OCF dipole. Since the radio has two antenna inputs, we dont need an antenna switch. However, this means that when the radio is not being used, the antennas stay actively connected to the radio.
Ive purchased a Paradan "automatic" Dual Antenna Disconnector (Dual Antenna Disconnector | Paradan Radio ) to disconnect the antennas from the radio when it is not in use.
Best practice is to leave the radio powered up with 12vdc and not physically "turned off". When a user is finished using the rig, he just closes SSDR on his PC and leaves the rig available for the next user.
The Paradan device can sense when 12vdc is applied to its connector and automatically connect the antennas. When 12vdc is removed, the device disconnects the antennas automatically with no user input needed. This is what I'm looking for! However, there is one problem: We never turn off the radio's 12vdc power and we never "remotely" press the front panel power button on the radio with the rear panel "soft power" switch. This means that the Paradan device would not be able to do its job.
Is there a hardware signal from the transceiver that I can attach a buffered relay to that turns on when SSDR connects and turns off when SSDR disconnects? Per the hardware manual, there is a 5vdc signal on a pin on the AUX connector. The manual does not elaborate when this voltage is present. This signal would then control the Paradan device to automatically connect and disconnect and ground both antennas from the rig when it is not in use. This functionality is important to us as we are located in the Lightning Capital of the USA, Central Florida.
I am not interested in a Node Red flow or other external additional interface devices... We want to keep this simple and automatic. All I need is either a dry contact to ground or a voltage to present itself in a hardware connector on the back panel of the radio when SSDR connects and go away when SSDR disconnects from the RF Deck.
Does this rig have that capability? I would test this, but the rig is not where I can easily access it at the moment to poke around with a voltmeter on. Im assuming the factory people would be able to answer this question.
Important Note: We DO NOT turn off the rig or remove DC power from it when we are not using it... This seems to be the best practice and has given us great stability. We only connect and disconnect SSDR to use the rig.
Thanks in advance for any input on how to integrate this solution.
