Seamless Integration of Outdoor Tuner

ChrisNia

I have a dual antenna coupler/tuner with the following I/O
+/- power supply
+12 volt signal wire to initiate tuning
+12 Volt signal wire from Coupler during tuning (Back to radio/it powers an led on control box while tuning is in progres)
+Antenna selector cable +12 volts = ANT 1 0V = ANT 2
+12 power source

I am using the Flex 8400 / PGXL / TGXL / Antenna Genius with Output module

Currently I have the output module switching power to tuner based upon band selection in the antenna genius table


Is there a way to program FLEX 8400 accessories port to send a tune command to coupler (+12V) if "TUNE" is selected in SMART SDR and inhibit transmit RF while +12 signal (In use) is being received from tuner?

Thank you

In furtherance to the previous post , I can confirm that the Antenna Coupler uses the same protocol and wiring as Kenwood and Icom outdoor tuners.

There:

Tune button
In Tuning LED indicator|
3 Position Switch for Antenna A or B
Setting switch to Middle grounds both antenna

is this a commercial tuner or home brew? I love the construction.

It is made here locally in Greece by a professional Electrical engineer, it has excellent characteristics;

It uses the ICOM protocol.

1KW DUAL MEMORY AUTO ANTENNA COUPLER

1. 1ΚW PEP (SSB) FOR 25 METER LONG ANTENNAS (1.6 - 30MHz)
2. 50 MEMORIES IN EACH ANTENNA OUTPUT (“A” AND “B”)
3. ANTENNA CHANGE WITHOUT RETUNING!
4. "TUNED" START UP AT THE LAST USED FREQUENCY!
5. MEMORY STORAGE WITHOUT USING BATTERIES!
6. RECEIVING COMMANDS FROM ICOM , ALINCO AND KENWOOD
7. 6pF OUTPUT CAPACITOR STEP!
8. DIRECT CONNECTION OF A DIPOLE BETWEEN OUTPUTS "Α" - "Β"!
9. GROUNDING OF NOT USED ANTENNA WHILE OPERATING THE OTHER!
10. GROUNDING BOTH ANTENNAS WHEN 12V SUPPLY IS CUT!
11. PROTECTION FROM STATIC DISCHARGE WHILE OPERATING!
