Automatic antenna switching (2025/05/17) 
I am using the now defunct MFJ/AMERITRON Remote Coax Switch RCS-10
(May 28, 2024 MFJ AMERITRON RCS-10 antenna switcher repair)

After switching the band of the radio with four antennas to switch.
I often accidentally forget to switch the RCS-10 antenna switcher

So I was searching the Internet for a solution to solve the problem.
OK2ZAW Jan Sustr'sHamparts.shopindicates certainty, emphasis, etc.BCD to 16 converterI found something called
Product to obtain 16-point output from BANDDATA at LINEAR terminal of YAESU radio

69 euros approx. 11,000 yen 4,300 pesos
 
Ordered after numerous email exchanges with OK2ZAW Jan
Shipped Czech Republic (Czechia) on April 11 and arrived in Ozamiz on May 16

Wiring the 15-pin DSUB that was ordered together with the FTDX3000 while reading the FTDX3000 manual
Switch the band from 1.9MHz to 50MHz and confirm that the INPUT to OUTPUT works properly
Next, check the RCS-10 schematic that Jan sent me.
Fortunately, the RCS-10 has eight input terminals.BCD to 16 converterConnect the output of
