We have left the old traces, connectors etc in exactly the same place. The software is backwards compatible with the previous versions. If your board has 12 mhz, you have to just edit that one line to change the second IF.
I have also written a new calibration rountine that makes it easy to calibrate without needing any instrumentation in the shack. You set the dial to the frequency of a known station, get into calibration mode, and then keep spinning the tuning knob until you are zero-beat with the known signal.

Specifically, the tx/rx LEDs that came with the custom case kit, and the N8DAH

be installed without having to scrape, cut and solder the fine traces?

of the pan-adapters I've seen around as well.

Anyway, this seems like a pretty good evolution of this radio!

I understand it is possible to change the display in the uBITX so that it shows transmit frequency.  But this may involve some painful (for me) wrestling with the Arduino IDE, Memory Manager and the new CEC software.  So I may leave well-enough alone.  Unless someone can tell me how to do this EASILY.

I have always preferred my dial to show my my TX carrier frequency whether or not it is suppressed. There are fiducial marks to show where to set for receive (USB or LSB).

If you operate near the (sub)band edge pay closer attention.

Transceivers are more often setup for the dial to to show the center of the SSB passband and often considered to 1500 Hz from the (suppressed) carrier.

In the end, you have to know how the radio you are using is configured. Either way (tx or rx reading) will work but if you are not aware which way your radio works you could transmit outside your license assignment. Your entire emitted signal is supposed to remain inside those prescribed band edges.

   well, you might be right, but when you zero beat a heathkit to a 100

   kHz marker, and subsequently tune in a CW signal, you will be

   transmitting on a DIFFERENT frequency from what your dial shows.       So I don't think you are correct for a heathkit SB-102, which I used

       No.

       You dial your receiver just the right amount off from the other

       station's zero beat so that either (a) you are set so that your

       transmitter will be on the other station's frequency and you can

       hear a nice tone from the other station or

       Either way.....you are NOT transmitting precisely where your

       dial says....because typically you are offset by about 800 Hz.

       My heathkit works the same way.

When I get a chance, I'll check one of my icom's and see what I do, but I suspect many rigs work exactly this way, so that it becomes easy to be right on frequency of the other station, and also hear WWV zero beat precisely at 10.000000 MHz.   If they worked some other way, WWV would not zero beat at 10.000000, or alternatively you would not be transmitting on the same frequency as the CW station you had put in the ccenter of your audio filter passband.
