The rest of the day and night was spent working on the interface to the Quadra amplifier. I must have spent ten hours on it and still had no joy in getting it to work. I am determined not to let it beat me, but I might take some time away from it to regather my thoughts. The problem is this amplifier is a Barrett 2075 which is basically a rebadged Yaesu FL-1000 Quadra. Barrett has changed the band switching from parallel BCD to serial 16-bit I2C-bus. I am attempting to bypass the serial and connect directly to the internal Quadra Band-Data 2 parallel BCD connection but the amplifier is very difficult to work on. Also when you read things like this about the connection diagrams in the Quadra manual “It is known that the Band Data 1 connection information from the Yaesu Quadra manual is incorrect in at least some instances. So proceed with caution until the Band Data 1 connection information is verified” it makes you wonder that any one has succeeded in interfacing this amplifier to anything? As well as this I am using a third party software program that seems to be working OK but I can’t get the band change data out of the PC parallel port. Never mind, I’m sure I will figure it out shortly.
Tomorrow I was planning to go to Auster Emperor Penguin rookery for the day but with the way the weather is today I think I will postpone the trip for finer conditions.
These ads have started to appear in our news papers and we are getting nervous about whether they will let us back in to Australia?
