! K9AY and 4-way Bi-dir beverage Controller
*''' This controller allows you to control:'''
** Simply K9AY - [link|https://remoteqth.com/k9ay-loops.php] (could be only over coax)
** K9AY++ RF box - [link|https://remoteqth.com/k9ay-loops-bpf-preamp.php] (coax + ctrl cable)
** Bi-DIR beverage TWO directions - [link|https://remoteqth.com/two-wire-beverage.php] (only over coax)
** Bi-DIR beverage FOUR directions with 4-way switch - [link|https://remoteqth.com/4-way-switch.php] (only over coax)
** You can use some features for more RX antennas

!RX ANT WAY switch
* '''There are two ways how to connect your RX antenna controller to your TRX (RX).'''
** 1. Using RX antenna port on your TRX. (Rear panel on your TRX or in Menu) [Example|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/new/controller_k9ay_4way_rx_way_switching_cable_connecting.png]
** 2. Using TX ANT port on your TRX (ANT1) and switch antennas by the controller. [Example|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/new/controller_k9ay_4way_rx_tx_way_switching.png]
'''Add 1:'''
'''{.redka#id color: #f23f37; font-size: 200%}⚠{/} MUST be RX ANT ONLY PORT on TRX, no TX!!!'''
* RX ANT NIIN and OUT on your TRX:
'''Add 2:'''

'''TX signal way during TXing:'''
'''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: RED LED TX must light ON when you TX!!! Do not forget to connect PTT RCA cable from TRX to Controller'''


* '''You can use RX antenna switch on Controller.'''
** this is ideal for TRX without RX only antenna port
** also for the rest TRX for fast RX antenna switching
** fast switching between TX antenna and RX antenna by knob on Controller
* '''If you want to use this feature you MUST use PTT IN to control relay for TX antenna!'''
*''' There is easy PTT loop on rear panel between two RCA connectors.'''
** PTT control works only in sniffer mode.
* '''PTT can continue to your PA over this box.'''
** works also when the controler is OFF
** there is no delay
** compatible with 5V PTT logic (as OM-power PAs)
'''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: PTT must be used!!!'''
!!'''RX SOURCE knob for fast switching of the RX way'''
'''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: RED LED TX must light ON when you TX PTT!!!'''

* '''There are two ACC connectors'''
** RJ45 and SUB-D
** First 8 wires are the same.
* ['''Please read this instruction, use ONLY Copper wires'''|https://remoteqth.com/wiki/index.php?page=CAT-5+and+CAT-6+control+cable+notes]
'''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: RJ45 is NOT LAN connection!!!'''

!Jumpers settings
!! Direction LED diode indication
* [bigger picture|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/FP_4.png]

!!K9AY or 4-way Bi-DIR switching matrix
* Select between switching matrix.
* K9AY and 4-way Bi-dir system do have different switching matrix table.
* [bigger picture|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/FP_1.png]

!!K9AY over coax
* This is for simply K9AY not for K9AY++ (there is switching over the control cable)
* '''SHORT jumpers''' for K9AY direction switching over the coax
* [bigger picture|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/FP_2.png]

!!4-way Bi-DIR beverage settings
*''' SHORT jumpers''' for right 4-way Bi-DIR beverage orientation. '''More here:[link|https://remoteqth.com/wiki/index.php?page=Antennas+configuration+-+feeders+positions]'''
* [bigger picture|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/jumper-4way_big.png]

!ANT Rload fine tune
* '''This is function is only for K9AY feeder with Variable Rload part.'''
* There are two ways for fine tunning of Rload. 
* Please check some more info about Feeder box of K9AY++ [on this link|https://remoteqth.com/wiki/index.php?page=K9AY+feeder+with+BPF&action#Rload_checking_the_resistance]
'''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: Final Rload resistance may vary with the direction switching. This is caused by thin GND wire between controller and RF feeder box. If the changing is lower than 10 % than all is OK, if more, than more GND wires are recommended. Using CAT-5 FTP (shielded) cable can be big advantage in this problem.'''
'''{.redka#id color: #f23f37; font-size: 200%}⚠{/} NOTE: For final tunning and measuring, please connect control cable as well also the coax one!'''


!Internal BPF and preamp PCB
!! This board is only in 4-way system controller. In K9AY++ set all this BPF and Preams are in K9AY++ feeder.
* It means that if you want to use K9AY++ controller also for 4-way beverage system, than you will have BPFs and Preamp ONLY for K9AY++
* If you want yo use this internal PCB board, than it is better to buy 4-way system controller + simply K9AY feeder.


!! Preamplifier GAIN
* With the '''variable ATT''' you can set gain of the Preamp as you need.
* '''Range is 0 to 17 dB'''
* [bigger picture|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/internal-pcb/deska_red_1.png]

!! Preamplifier BIAS
* With this '''trimmer''' you can set right bias for the transistor.
* Bias vs IP3 and gain parameters are there: [OK2ZAW's blog spot|https://ok2zaw.blogspot.com/2015/09/rx-ant-switching-b-ox-part-2-preamp-ip3.html]
* recomended bias is 45 to 70 mA for 13 V+

!! BPF bypass
* You can use one of '''three BPF (160, 80 or 40m)''' or you can'''ByPass''' it for wideband operation
* Controller by switch on the front panel - number 4 on [controller|https://remoteqth.com/img/ZAW-WIKI/k9-bidir-controller/controller_k9ay_4way_popisky.png]
