Re: SPI speed set to 10 MHz
Jack is at ham fest and has limited access.? I am going to lock variables down for programming safety and try to speed up processing.? I am looking for upgrades also.

This could be a simple oversight in library modification, since it is buried one directory level below and would not affect functionality.
I don't have hardware built to test, but I verified through adding a pragma message that in the lib RA8875\_settings\RA8875UserSettings.h
that?SPI_HAS_TRANSACTION is defined.
MK20 case sets MAXSPISPEED = 22000000UL
MK66 should be able to do the same (pending wire-up limitations, etc)
Currently not defined and it falls through to default.
Might make things a little snappier.? Might be a place to tune out possible harmonic issues. Speed might be limited to wire length and routing. Might be a total don't care. Might be that I am out to lunch figuratively, because I am literally.
Thought I would pass along the observation before I forget, and if this is an area for improvement, that others don't wait until I get around to building.
Also same if/else type statement in "_utility", but that doesn't appear to be used in the JackAl code.

Re: CW Operators: Something to think about before you drill your case
Al's going to post his template. The only catch is that the logal has to remain unchnaged Jack, W8TEE

Re: JackAl Compatibility with uBITX v5
I posted yesterday that we expect some changes but not many. We have two new boards on order and will not know for sure until we test those... I will report what we find.

I haven't yet had a chance to dig into the details, but given the change in the uBITX IF to 11.059 MHz, is the JackAl board still compatible?? Are there other changes that might be relevant here?? I'm filling my JackAL BOM and just ordered my 4th? uBITX, this one v 5.

Jack, I really would appreciate your advice as to whether the above procedure for mounting the Teensy and its audio board is correct.? Yes I have studied your photo of your arrangement but it is essentially a top view and does not show anything under the Teensy board.? Soldering errors on expensive Teensy and audio boards are hard to correct. (Expensive when you add to freight to Downunder).

Mike, please look at
and scroll down to Paul's solution.? "replacing the pde.jar"
Paul supplies a pde.zip enclosure and instructions.
We all should take notice of how the original poster of the problem (Redgeneral) in the pjrc forum provided concise details of the issue.

Just got mine yesterday Feb 5 and ordered it right before they left for the holidays.

Mike and All:
An attachment with the error messages is a good start, but more than that is always needed when you do a bug report. We need to know details, like:
What PC is hosting the Arduino IDE? How much memory does your system have?
What is the op system and which release (e.g., Win 10)? What is the directory path that holds the IDE? What is the directory path to the JackAl INO source code file? What release of the IDE are you using. What release of the JackAlV???? are you using?
There are probably others I will think of as I press the Send button, but this is a start.
Mike: all of your errors appear to be Java related. Those likely occur before the IDE is loaded. I would check your Java installation first.

We have ordered two units for testing and Al is looking at the schematics, but we just found out about this today. We'll look into things as quickly as we can.

I have iDC connectors, and SMA connectors, encoders, and probably other stuff available.

Ron,
It look correct by your picture. ?You will not use any of the connectors pre-installed but you¡¯ll be soldering (using header pins or directly) to JP1 and JP2 which should be empty through holes on the right side of the display if the display ribbon is at bottom. ?JP2 only gets the INT signal and JP1 gets the rest.

Finally got my 5" display from buydisplay, but it doesn't look much like the pictures in the manual, (slightly blurry photo). Mine came with a tiny connector, but no labels, and the left edge appears to have mounting holes for 3 edge connectors.
Wonder if anyone has more detail on connecting displays?
Thanks
