Re: Transmit IQ Calibration
Al, I was using Ver66-4 and was successful doing the Frequency C
and Receive IQ Cal. All Bands were -75 to 80 Db. I had moved the
Temp display to the Top but it was cutting off the top of the
Fonts so I moved it up a few pixels. When I rcompied, I got a
message about updated libraries available and foolishly click ok.
I was not able to compile(some variables not found). I tried
chasing them down, but finally gave up. So I reset the Teensy back
to Blink and reloaded all of the libraries, including Teensyduino.
Finally compiled but system hangs at the Splash Screen. Today I
tried 66-7, compiled with "Faster wit LTO", 528MHz, and Serial. It
compiled and hangs on the Splash Screen and nothing on Serial
Monitor. I normally use Dual Serial, so I tried that and it
doesn't even get to the Splash Screen. Not sure what to try next.

My guess is that you are using one of the optimize options that
minimizes memory, and something is overwriting another variable
or the stack.
Try the settings above and see what happens.

Thanks
Al.? I have loaded the new SW after erasing the Teensy memory.?
The T41 boots with version 66.8, even though the zip file says

? It's a single hop from here.? Strong signals.? I had put away the MFJ loop before I heard they were on 15M too.

Re: Bill's SSB Contest Station J62K 28.452
The “59” thing is automatic but most signals really were 59…. Repeats were more due to noise. ?
