Hey all thought I would post a new element I have been playing with,? had some good audio reports with this one after some testing I have decided to keep it. JLI Electronics (

Hi Everybody, I just uploaded a file which describes a hardware and software modification to the uBITX to interface a resistive keypad.? See kb1oiq_ubitx_keypad.pdf if interested. Enjoy! Thanks,

What are you using for an antenna? Vince.

David Thanks for very important information. that is my mistake. i plan release version 1.0 from version 0.35 with fixed it. Thanks again, David. Ian KD8CEC 2018-02-07 7:49 GMT+09:00 David S via

Thanks guys! Roy WA0YMH

Turned the output down to about 8 Watts and have made 4 contacts on 160 with great reports. Will add a larger heat sink to be safe.

No need to add a library for si5351 support when using Allard's Bitx40 code that is version 1.20 and beyond (including all of the 2.* releases, and Farhan's uBitx code) The si5351 support is compiled

OK guys, my bad on Allards raduino sketch.? after a nap and some diligence i realized i did not have the Pinchange library installed. this is the first time i have ever seen a library installed

I don’t have a spectrum analyzer but I think your right. Without the LPF installed I’m seeing over 20 Watts out on 160m and with it I see 12watts out so a lot of signal outside of the 160m band is

Bill: I think what you are seeing is the "normal" variation in the output of the MOSFETS. Some are better than others at RF. Gordon's suggestion to turn back the drive is probably the right

Right I could do that and use it just on 160m. So as is I’m seeing about 2 amps on 80m and it goes down as I switch to the higher bands. So going lower from 80m to 160m I jump over an amp to

Bill, if you're worried about your finals just turn the drive back a bit.

Did you read the documentation for 1.27.7? Allard does a great job documenting exactly what you need and how to get it. You need to add that library into the IDE. Marco - KG5PRT [email protected]>

Doing some testing with my uBitx on 160m with a 160m LPF attached to the output. I’m seeing about 15 Watts out but the current draw is running very high at just over 3 amps. So not usable on 160m at

Use a new Raduino version that has SI5351 routines built in?? I was written to help those problems. I uses a lot less memory and avoids all the problems with libraries. You probably want all the

UPDATE:l GIVING UP TODAY on the dons shuttle sketch i tried allards 1.27.7 without pesky library issue now it spews off a pinchange interrupt issute. final exit 1 arduino nano. drink time, <JK? DAVE

Ian Now on version 0.35, another great increase in flexibility, thanks, I been trying the memory function, storing the FT8 frequencies, a small wrinkle, whilst the correct frequency is recovered from

Sorry...I found the hex files Thanks!

Ian, ?Any chance of including the hex files so we can just upload with Xloader? Thanks! Mike WA3O

Ok, i need a pointer here. i got bitx40 last week so i plugged in the raduino portion. bad connector on nano but i will fix that, no problem.? i dont care for green so i plugged a blue/ white 16/2
