Configuration, RRC 1258 / K3 Twins with resistor on mic bias strapping
« on: 2022-02-09, 16:15:04 »
I have purchased a preowned set of RRC1258 units that were factory strapped by Flex. I notice on the Control unit there is a small resistor on the mic bias strap instead of a straight strap and also the J2 Jumper was set to open (9V) instead of the common 8 V position.
I want to use them strapped as Yaesu FT2000 so it will work with the Electric mic I will be using for the Flex 6600. I changed J2 to provide the 8V mic bias vltg to be provided by the RRC unit. Should I be using the resistor also or just strap the mic bias as shown in the RRC manual for the FT2000.
Also, I am "assuming" that the FT2000 is the correct use for also using cw and mic only to drive the Flex 6600. No other use for the RRC boxes is intended.
Thanks for any help
