I did a quick five minute test (it’s late here) with an audio signal generator and likewise got no TX output. Roger G8JWT

Hi Al, Tried your suggestion regarding the tone using Ver066_3. Applied a 1K tone to the mike jack, keyed the PTT no audio. Audio into the audio card but nothing coming out on the scope. Tried with a

*** That's probably because they belong to Bill K9HZ. There are boards that he designed that have become de facto standards for V12. I think - his PA, his LPF, his LPF control card, his BPF. Those

Hi Al, Thanks for clarifying the need for the user supplied audio tone during xmit IQ cal. I will give that a try and report back. Rick, KN4AIE ________________________________ Sent: Thursday,

Bob, Attached is a report showing what I did on 6M. See the chart on pg 2. dave, n3ds [email protected]> wrote:

To Everyone having problems with SSB calibration, especially SSB PA power. I did not make it very clear that a signal must be applied to the Mic jack. I will emphasize this in the final version of the

Al, 66.3 seems to have improved the button response but hasn't cured TX calibrate issue. All I can see on my spectrum analyser is a very low level carrier around -90dBm. Roger G8JWT

I started to wind the coils for the 6m band and am confused about L601, L603, and L605. The directions say L601 and L605 are 39nH, 5" 24AWG, 5 turns on a 1/8" drill bit. However, L603 is 24nH, 4"

I can view and down load PDF's fine. I think some of the V12 Schematics in PDF format are missing from Git Hub though. Tim W4YN

Whose PDFs and from where? The fact that there don't seem to be others with the problem, perhaps your viewer isn't working correctly. Can you view PDFs from other sources? Jack, W8TEE

Over the last couple of days I've made attempts to view the .pdf files, both on my Ubuntu desktop and a Win& laptop at work.? The .pdf are not working, instead I have this message: Unable to render

Actually you can mix and match the earlier version boards with the newer versions… check the upgrade paths on my GITHUB here: T41/T41_Upgrade_Paths at main · DRWJSCHMIDT/T41

Hi Al, Tried your latest release 066-3 and still cannot get IQ xmit cal to work. RF is a little better but no tone or very low. Thinking I might have a problem I loaded in a release from 01-07-25,

This version fixes the button response problem in Receive Cal and a couple of other small issues. Al AC8GY

Same thing here. Very weak carrier at -80dBm. Nothing more. G8JWT

Just started the xmit cal, also no tone on PTT, seems like a weak carrier is present. Previous version 3 or 4 weeks ago, Olivers release, worked ok on xmit using my tiny SA. Rec cal works fine. Rick,

Thanks Al and Oliver for the new code and instructions. I have run through the freq cal and receive cal with no problem. I have a receiver/SA hooked up to the Ant1 out, and am, in the Calibrate TX

I reset the Teensy and loaded the version 66.1 S/W. Everything seems to work. I did the Frequency Calibration with a GDO @10MHz and got ~0.1Hz error. However, when I tried the Receive IQ Calibration,
