I sent out five of those new display driver boards about a week ago and only saw posted that Terrance got his working as was able to use a 3-foot long display cable without display-T41 errors/lockups. ?Anyone else built it yet? ?I know i didnt publish an assembly manual before i headed out of the country but the thing is pretty simple and i did send out a note re how to make it work on 5v or 3.3v. ?
Anyone else? ? I think its a winner but would like to know so i can get parts and boards ordered to send these out before Hamvention

Bill, I have not had time to get to it: working on the book, update helping my grandson study for his pilot exam, etc. As soon as I can i will try it out.

Got it yesterday, heading out to the workshop to build it. May
have missed your note on 5v/3.3v.

Completed the build for 5V. No shorts, no opens, and all
connections traced and ok. However, with the Board in place, no
Display. Checked it twice and made sure that both connectors were
fully seated. The system still works without it, so no harm. I'll
try again later and check some voltages.

It is now working. I reflowed all of the connector pins and
verified that there was 5V on the out connector. Apparently a bad
solder joint, they looked fine though. I was able to compile and
load Ver66.9 with Faster with LTO, 528 MHz, and Dual Serial. This
would only run at 600MHz prior to the Driver board. Still not sure
why defining TCXO causes the 528MHz issue. I'll make a longer
Display cable and try it, current one is ~3".

However, with the Board in place, no Display. Checked it twice and made sure that both connectors were fully seated. The system still works without it, so no harm. I'll try again later and check some voltages. On 3/31/2025 6:36 AM, Oliver KI3P via groups.io wrote: On Sunday, March 30th, 2025 at 2:47 PM, Robert Luken W3RDL via groups.io <now.w3rdl@...> wrote:
Got it yesterday, heading out to the workshop to build it. May have missed your note on 5v/3.3v.

Anyone else built it yet? I know i didnt publish an assembly manual before i headed out of the country but the thing is pretty simple and i did send out a note re how to make it work on 5v or 3.3v. Anyone else? I think its a winner but would like to know so i can get parts and boards ordered to send these out before Hamvention ? Dr. William J.
