[Yaesu] FT-1000D firmware upgrade

[Joe Subich, W4TV]

Jim, 

Which version of ROM does your FT-1000D use?  Hold the 1.5 and 7 
buttons while turning on the radio.  This will perform the "Las 
Vegas" test and display the firmware version. 

Firmware version 6.0 is the latest available for the unit.

If you have Firmware version 6., try adding a 1.5 K resistor from 
serial out (pin 2 of the CAT DIN) to ground.  The FT-1000D (and 
FT-990) use an open emitter transistor to drive SO.  It does not 
include a "pull down" resistor.  The input of many TTL to RS-232 
converters (including the ARRL Handbook design) that use 7407 TTL 
buffers are not pulled down well enough to be reliable.  The 
"missing" pull down is independent of the firmware version.  At 
some point, Yaesu began adding the pull down to production units.
