the T41. MY K9HZ 20W PA, 100W PA, LPF, Antenna Tuner, etc are all my design that I sell for multiple radios in addition to the T41... so the only thing I don't provide with those are the gerbers.

I think - his PA, his LPF, his LPF control card, his BPF. Those cards are in a different area of his github. - Jerry, KF6VB |

Re: T41 BPF 6m confusion
Yeah that's probably wrong. See the instructions. It follows Olivers report.

The directions say L601 and L605 are 39nH, 5" 24AWG, 5 turns on a 1/8" drill bit. However, L603 is 24nH, 4" 24AWG, 7 turns on a 1/8" drill bit. How can 7 turns require less wire than 5 turns and how can 7 turns have less inductance than 5 turns? Bob W3RDL -- This email has been checked for viruses by Avast antivirus software. www.avast.com |

Re: [AmateurRadioBuilders] RP Pico 2
Check: Earlier Picos could be overclocked at 150MHz, but that overclocking often comes with caveats about doing that. Jack, W8TEE

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 about the Pi Pico 2 though? Having said that, the Pi Pico 2 is interesting because¡ - it already clocks at 150MHz - it has FPU and DSP on the arm cores - is available as a ¡®W¡¯ version already (for about ?6.60 in the UK) with 4MB flash and 520KB RAM I won¡¯t be surprised if a speed bump for Pico2 is announced later, but it has taken some time for that to come for Pico(original), and the Pico2 has not been out that long, so I guess we wait and see.

The Pico W has 26 I/O pins, 2Mb of Flash, and WiFi/Bluetooth support. No price was given for the Pico 2 nor did it say anything about WiFi/Bluetooth support, but the standard Pico W is about $8-$10.

Alternative to Pico?
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. I have used earlier versions of this microprocessor and is compatible with the Arduino IDE and libraries...I haven't found a library yet that didn't work, but there may be some. I use this over the Nano--the clock is 2x faster, a lot more memory, and a much smaller footprint. I don't know if it speed is fast enough for T41 I/O duties.

RP Pico 2
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: PICO_USE_FASTEST_SUPPORTED_CLOCK=1. I don't know if the Arduino IDE recognizes this or not. There's been interest here in using the Pico as a second I/O processor in the T41. The Pico W has 26 I/O pins, 2Mb of Flash, and WiFi/Bluetooth support. No price was given for the Pico 2 nor did it say anything about WiFi/Bluetooth support, but the standard Pico W is about $8-$10. If I see additional info, I'll post it here.
