Re: Yaesu 8 pin min din - JUMA PA1000

Hi Billy,

Pse check that you have set JUMA PA1000 for BCD band data. Push the PAGE button until you are on Band Data page and select BCD with the up/dwn buttons.

You may also need to set something in FTDX10, like in FT-891 menu item 16-15 to "LAMP" (Linear Amplifier).

Re: PA1000 Standby/Off power

Ian, I have tested only 100W but I don't see any problem with 200W thru PA1000 when it is STBY or power OFF. The TRX connector is connected to ANT connector via T/R relay and a 100nF capacitor.
