USB BCD Cable - BCD code for 17 meter band supposedly incorrect

  • Updated 1 year ago
USB BCD (parallel FT245) cable - all bands except for the 17 meter band provide the correct BCD code. BCD code for 17 meter band should be 00110 but I get 00000 instead (which is the code for the 60 meter band).

Can anyone confirm my observation?

Are you sure you've tuned the slice to 17M, and not something nearby?  Assuming the cable is configured to track the frequency of the TX slice (there are several options), if the TX slice is tuned outside of the allowed band, the transmitter goes dark and zero will be emitted on the BCD cable.

I was tuned out of the 17m band :-( Thanks for confirming that it was me that was doing wrong ;-)

My AMP follows the radio and a BCD Relay board to 17 Meter just fine, check your Frequency as Dave has commented.

I connected directly to the bcd14 board and did not need a powered hub. It works great with no problems. You will be pleased.

joe,

Thanks for the info, that is what I needed to know.  I wanted to take advantage of the isolation between the radio and the amplifier that the opto isolator  provided.

Joe,

Sorry about the late reply. I was pre-occupied building another 2x LDMOS amp. I finally got the BCD14 and the C232... USB cable in house here. 

Will be giving them a try shortly. Did you have to give your BCD board 12v or does it get power from the USB cable?

Any other hints appreciated. I could look at the datasheets for both, but it's more fun to talk to another ham. :)

Thanks!

For what its worth i have the W6PQL amp connected to my 6500  with the USB BCD cable.  The BCD 14 gets its12 volts from the amp. the USB cable just supplies the drive to the Opto  devices.  The USB connection could not supply 12 Volts 5 Volts at best.. I also liked having the radio isolated from the amp as much as possible.  The system is working perfectly.

Hi Rob,
I used the 12 vdc from the amp control board, it doesn't require much amperage. The only thing I added was a front panel push button that toggled between grounds at either the bcd selection or the front selector switch, this gave me a front panel selection of manual/auto. You will be very pleased with the operation.
