Press Band to Save/Exit – You can test new setting but must restart (Pwr Off/On) for changes to be memorized

Menu Settings:

Screenshot of the standard menu with factory settings. Some adjustments can be made to these settings to improve the way the transceiver works to suit your needs.

COM Port:

FX-9A_HF_9_Band_QRP_transceiver-5Serial connection to PC – uses TS-590 Protocols

The rig control using HRD only. The radio uses the TS-590 commands and the speed is 115200.

Any homemade rig cable using USB to serial converter and a 3.5mm connector should work.

The pins are:
Tip – pin 3 TX
Ring – pin 2 RX
Sleeve – pin 5 gnd

The unit can be used for JT65, PSK, RTTY and SSTV, using standard software packages available on line (FREE).

This port is also used for HRD software for PC control.





Ant (BNC): 50Ω antenna connection Key: (iambic keying mode A and B)
Mic: Dynamic Type Power: 3.5mm Power connector
Phones: Headphone socket Com Port: 3.5mm Jack
Phones: Headphone socket  

Internal PCB

To access internal board – take off side covers but DO NOT remove screws on back of case as they hold final transistor heatsinks and transmit board to case.

Be aware of a small black wire on right side which connect control board to receive board, it can be un-clipped easily. If it is unseated, you will not hear receive signals. Gently reseat it.


source code modify at 19-Feb-2017

modify the broadband CW mode LO and BFO frequency settings, to solve the problem of false signal reception.
