Hi Jack, do you have any links where we can see that info about the *pi pico 2*? afaict, news has been released that the original Pi Pico has been bumped from 133MHz to 200MHz. I don’t see anything

All: I've also experimented with the XIAO processor from Seeed Studio. It's about the size of your thumbnail and costs $5: It has 256K of flash and 32K of SRAM with 19 general I/O pins, ADC/DAC pins.

Just looking at the T41 and K9HZ repos and I can't find the gerbers for either the normal encoder or dual encoder board. I already have the normal encoder board obviously but I am interested in

All: I just read that the RP Pico 2 is now capable of running at 200MHz, up from 133MHz earlier. Using CMake, the new speed setting in the compiler is a symbolic constant:

Here is a revised version of the V66.4 calibration PDF. Al AC8GY

Thanks Albert, SDT66_3 was the first build of the code that actually worked properly for me, appreciate all the hard work from yourself, Jack, Bill, Oliver and the others who have contributed to the

Hi Everyone, Had some good feedback on the versions 66.1 and 66.3. The attached update fixes the known problems. Fixes include issues with the SSB transmit cal and power levels, which were caused

With 1kHz from a signal generator into the audio hat and the radio in TX mode I'm not seeing any IQ output from the hat. The three clocks seem to be present although I'm not sure what frequency they

Good news, checked again tonight and I didn't get any error messages. The problem happened on my home desktop and my work Windows 7Pro laptop, thankfully I'm not having any problems now. When it did

I also get no audio out with audio generator to audio hat. I also get no output on cw so maybe I have something else wrong dave, n3ds

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
