If you use a microHAM Interface with a Yaesu FT-9000 and are contemplating the "PEP" firmware upgrade, the new firmware creates an incompatibility with all microHAM interfaces. The original FT-9000 firmware did not use (did not implement) CTS/RTS handshake on the CAT port. As such, microHAM DB37 cables (microKEYER, microKEYER II, MK2R/MK2R+) do not include connections for RTS/CTS between the keyer and the FT-9000 and DB15 cables (USB Interface, II, USB Interface III, DigiKeyer) do not include "fake handshake" or an RTS pull-up resistor to keep the transceiver "happy." If you have a Yaesu FT-9000 (any version) with "PEP" firmware, you will need to disable the handshake by setting Menu 36 (CAT RTS) to "Disable" in order for the FT-9000 to respond to any CAT input. This change in the Yaesu firmware may also result in problems with some software that does not provide RTS/CTS handshake in the built in FT-9000 support when used with a "normal" serial port (but not with a microHAM interface). ______________________________________________________________ Dx4win mailing list Home: http://mailman.qth.net/mailman/listinfo/dx4win Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
