Dave, K7PDW here. I have the same problem with the same driver #20 plus another problem. My PROii drops out of USB-D back to USB and that cause my SignalinkUSB to loose connection to the radio. Seems like the "set rig" command sets the radio back to some kinds of a default setting.

Hi Dennis,

Current driver #20: Started with rig set to wide 3.ok filter. Changed mode then freq, it changes the width to the medium 2.4 k filter. Note that changing the mode alone changes the filter.

Driver #16: Same as above, as soon as you change the mode it changes the filter width to the medium 2.4k filter.

I tried some of the non-legacy drivers but not all of them work, most don't and I get errors with most of them or they work while in LOGic but when I shut LOGic down and re-launch I get errors. Its been awhile since I brought this up but since #20 was working without error I was fine, and still ok.

I did get #46 to load and it did the same thing, also tried the driver that supports changing the filter width (#48 or #49), it worked keeping the filter width as set. These drivers don't work for long giving errors or not functioning with set rig, some of the controls don't toggle when operating the rig. Like changing to split on the rig doesn't toggle the radio button in the rig control window, several other function changes on the rig don't change the radio buttons in the rig control window.

Sometime ago I put every driver for the IC-756 through a function test and recorded the results for all the features....misplaced that "pile" of post-it notes. I'll do that again after I do a clean install of Win 10. I may have some baggage on this PC that could be causing some issues. Currently running Win 10 but only did the upgrade. My PC is a Lenovo (don't buy one) and it has a mess of programs that it doesn't know it needs, nor does Lenovo, or the upgrade procedure they published, or the driver webpage, basically you cant figure out what is needed or not. Anyways, getting off subject.

Note also that the same thing occurs with my IC-746Pro, driver #16. Same steps as above, changing mode alone changes the filter to the medium filter.

Dave,

Ok, well as someone with a 756ProII i'm curious if you attempted any of the other drivers, like #46 or #48. Curious if they load and run without errors. The non-legacy drivers have been an issue for me, and apparently not many Icom users on the forum so don't get much feedback either way as to how they are working for them. I'm functioning just fine with #20 and set rig works great as well as the important stuff. The filter re-setting was getting old, but, I thought maybe there was a setting in LOGic buried somewhere that I didn't know about. Anyways if you try the other drivers let us know.

Dave,

Ok, well, wow. That's a mouthful of issues. I haven't used the digital modes for quite some time so can't say if the same issues result here. The filter issues of course do. I used to run JT65, WSJT, and a host of others without issue. Don't have experience with the SignalLink. I run dual CT-17's, one for the 756ProII and one for the 746Pro which solved issues from running both on one CT-17 with CI-V Transceive on in both rigs as they "followed" each other, I called it nuisance tracking. I'm curious and will try some digi this weekend and report back any issues.

Good Luck, 73, de Brad
