Subject: BF-100 no longer works with SmartSDR 4.2.18 (Flex 6700)

Hi all,
Has anyone else had problems with the SureFire BF-100 bandpass filter after updating to SmartSDR 4.2.18?
I use a Flex 6700 with the BF-100 connected via FTDI USB cable (C232HD) on the accessory port. It worked fine on previous versions.

Now:

  • When USB cable is set to Bit mode → Panadapter works normally (signals visible), but the BF-100 does not switch bands at all.
  • When set to CAT mode → No signals in the panadapter and BF-100 does not switch.

Anyone else seeing this with 4.2.18 + BF-100? Any solutions or workarounds?
Thanks, 73, AK1MD

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
